Why two NDCs? The FDA registers this code as 0409-0120-01 — a 4-4-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the labeler segment → 00409-0120-01. Same drug, same package — only the format differs.

Label name DAPTOMYCIN 350 MG VIAL Ingredient Daptomycin

📖 What it is MedlinePlus · NLM

Daptomycin injection is used to treat certain blood infections or serious skin infections caused by bacteria in adults and children 1 year of age and older. Daptomycin injection is in a class of medications called cyclic lipopeptide antibiotics. It works by killing bacteria. Antibiotics such as daptomycin injection will not work for treating colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

2 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?

Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?

No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.

Why might an inactive ingredient be missing?

Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.

Can inactive ingredients matter?

Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

NADAC price history (per ea) — tap or hover for the price & month

Where does this data come from?

NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

🏛️FDA exclusivity

FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.

🧪Product / substance patents

Patents covering the active ingredient, product, formulation, or related drug features.

🎯Method-of-use patents

Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.

🛈 What do these terms mean?

Patent: Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent: Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent: Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent: A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label: A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity: FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV: A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS: Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating: FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity): The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions

Is there a generic version of DAPTOMYCIN 350 MG VIAL?

Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for DAPTOMYCIN 350 MG VIAL. See the alternatives section for substitutable, lower-cost products.

The FDA approved a generic — why can’t I get it at my pharmacy yet?

FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.

Why do different websites show different generic release dates?

Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.

What does “FDA listed” mean?

It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.

What does a patent or protection date mean here?

It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).

What does “current Orange Book estimate” mean?

It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.

Can a generic come out before the last patent expires?

Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.

Can a generic come out after the listed dates?

Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.

What is the difference between patents and exclusivity?

Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.

Why are there multiple patent dates?

One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.

Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.

Where does this data come from?

Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 00409-0120-01, not the drug overall. Other pack sizes report separately.

💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

📅 Q1 2025 – Q4 2025 · 4 quarters of data

( 1.3 ) • Daptomycin for Injection is not indicated for the treatment of pneumonia.

( 1.3 ) • Daptomycin for Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus . ( 1.3 ) • Daptomycin for Injection is not recommended in pediatric patients younger than one year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs. ( 1.3 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin for Injection and other antibacterial drugs, Daptomycin for Injection should be used to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

( 1.4 )

1.1Complicated Skin and Skin Structure Infections (cSSSI) Daptomycin for Injection is indicated for the treatment of adult patients with complicated skin and skin structure infections (cSSSI) caused by susceptible isolates of the following Gram-positive bacteria: Staphylococcus aureus (including methicillin-resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus dysgalactiae subsp. equisimilis, and Enterococcus faecalis (vancomycin-susceptible isolates only).

1.2Staphylococcus aureus Bloodstream Infections (Bacteremia) in Adult Patients, Including Those with Right-Sided Infective Endocarditis, Caused by Methicillin-Susceptible and Methicillin-Resistant Isolates Daptomycin for Injection is indicated for the treatment of adult patients with Staphylococcus aureus bloodstream infections (bacteremia), including adult patients with right-sided infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates.

1.3Limitations of Use This Daptomycin for Injection product is not approved for use in pediatric patients [see Use in Specific Populations (8.4) ] . Daptomycin for Injection is not indicated for the treatment of pneumonia. Daptomycin for Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus .

The clinical trial of daptomycin for injection in adult patients with S. aureus bloodstream infections included limited data from patients with left-sided infective endocarditis; outcomes in these patients were poor [see Clinical Studies (14.2) ] . Daptomycin for Injection has not been studied in patients with prosthetic valve endocarditis. Daptomycin for Injection is not recommended in pediatric patients younger than 1 year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs [see Warnings and Precautions (5.7) and Nonclinical Toxicology (13.2) ] .

1.4Usage Appropriate specimens for microbiological examination should be obtained in order to isolate and identify the causative pathogens and to determine their susceptibility to daptomycin. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin for Injection and other antibacterial drugs, Daptomycin for Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information is available, it should be considered in selecting or modifying antibacterial therapy.

In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Empiric therapy may be initiated while awaiting test results.

5.1Anaphylaxis/Hypersensitivity Reactions Anaphylaxis/hypersensitivity reactions have been reported with the use of antibacterial agents, including daptomycin for injection, and may be life-threatening. If an allergic reaction to Daptomycin for Injection occurs, discontinue the drug and institute appropriate therapy [see Adverse Reactions (6.2) ] .

5.2Myopathy and Rhabdomyolysis Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CPK) values to greater than 10 times the upper limit of normal (ULN), has been reported with the use of daptomycin for injection. Rhabdomyolysis, with or without acute renal failure, has been reported [see Adverse Reactions (6.2) ] . Patients receiving Daptomycin for Injection should be monitored for the development of muscle pain or weakness, particularly of the distal extremities.

In patients who receive Daptomycin for Injection, CPK levels should be monitored weekly, and more frequently in patients who received recent prior or concomitant therapy with an HMG-CoA reductase inhibitor or in whom elevations in CPK occur during treatment with Daptomycin for Injection. In adult patients with renal impairment, both renal function and CPK should be monitored more frequently than once weekly [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ]. In Phase 1 studies and Phase 2 clinical trials in adults, CPK elevations appeared to be more frequent when daptomycin for injection was dosed more than once daily.

Therefore, Daptomycin for Injection should not be dosed more frequently than once a day. Daptomycin for Injection should be discontinued in patients with unexplained signs and symptoms of myopathy in conjunction with CPK elevations to levels >1,000 U/L (~5× ULN), and in patients without reported symptoms who have marked elevations in CPK, with levels >2,000 U/L (≥10× ULN). In addition, consideration should be given to suspending agents associated with rhabdomyolysis, such as HMG-CoA reductase inhibitors, temporarily in patients receiving Daptomycin for Injection [see Drug Interactions (7.1) ].

5.3Eosinophilic Pneumonia Eosinophilic pneumonia has been reported in patients receiving daptomycin for injection [see Adverse Reactions (6.2) ] . In reported cases associated with daptomycin for injection, patients developed fever, dyspnea with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates or organizing pneumonia. In general, patients developed eosinophilic pneumonia 2 to 4 weeks after starting daptomycin for injection, and improved when daptomycin for injection was discontinued and steroid therapy was in…

7 DRUG INTERACTIONS

7.1HMG-CoA Reductase Inhibitors In healthy adult subjects, concomitant administration of daptomycin and simvastatin had no effect on plasma trough concentrations of simvastatin, and there were no reports of skeletal myopathy [see Clinical Pharmacology (12.3) ]. However, inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of creatine phosphokinase (CPK). In the adult Phase 3 S. aureus bacteremia/endocarditis trial, some patients who received prior or concomitant treatment with an HMG-CoA reductase inhibitor developed elevated CPK [see Adverse Reactions (6.1) ].

Experience with the co-administration of HMG-CoA reductase inhibitors and daptomycin in patients is limited; therefore, consideration should be given to suspending use of HMG-CoA reductase inhibitors temporarily in patients receiving Daptomycin for Injection.

7.2Drug-Laboratory Test Interactions Clinically relevant plasma concentrations of daptomycin have been observed to cause a significant concentration-dependent false prolongation of prothrombin time (PT) and elevation of International Normalized Ratio (INR) when certain recombinant thromboplastin reagents are utilized for the assay. The possibility of an erroneously elevated PT/INR result due to interaction with a recombinant thromboplastin reagent may be minimized by drawing specimens for PT or INR testing near the time of trough plasma concentrations of daptomycin.

However, sufficient daptomycin concentrations may be present at trough to cause interaction. If confronted with an abnormally high PT/INR result in a patient being treated with daptomycin, it is recommended that clinicians: 1. Repeat the assessment of PT/INR, requesting that the specimen be drawn just prior to the next Daptomycin for Injection dose (i.e., at trough concentration).

If the PT/INR value obtained at trough remains substantially elevated above what would otherwise be expected, consider evaluating PT/INR utilizing an alternative method. 2. Evaluate for other causes of abnormally elevated PT/INR results.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Limited published data on use of daptomycin in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage. In animal reproduction studies performed in rats and rabbits daptomycin was administered intravenously during organogenesis at doses 2 and 4-times, respectively, the recommended 6 mg/kg human dose (on a body surface area basis). No evidence of adverse developmental outcomes was observed.

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.

Data Animal Data In pregnant rats, daptomycin was administered intravenously at doses of 5, 20, or 75 mg/kg/day during the gestation days 6 to 18. Maternal body weight gain was decreased at 75 mg/kg/day. No embryo/fetal effects were noted at the highest dose of 75 mg/kg/day, a dose approximately 2-fold higher than in humans at the recommended maximum dose of 6 mg/kg (based on body surface area).

In pregnant rabbits, daptomycin was administered intravenously at doses of 5, 20, or 75 mg/kg/day during the gestation days 6 to 15. Maternal body weight gain and food consumption were decreased at 75 mg/kg/day. No embryo/fetal effects were noted at the highest dose of 75 mg/kg/day, a dose approximately 4-fold higher than in humans at the maximum recommended dose of 6mg/kg (based on body surface area).

In a combined fertility and pre/postnatal development study, daptomycin was administered intravenously to female rats at doses of 2, 25, 75 mg/kg/day from 14 days pre-mating through lactation/postpartum day 20). No effects on pre/postnatal development were observed up to the highest dose of 75 mg/kg/day, a dose approximately 2-fold higher than the maximum recommended human dose of 6 mg/kg (based on body surface area) 1 .

8.2Lactation Risk Summary Limited published data report that daptomycin is present in human milk at infant doses of 0.1% of the maternal dose (see Data ) 2,3,4 . There is no information on the effects of daptomycin on the breastfed infant or the effects of daptomycin on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Daptomycin for Injection and any potential adverse effects on the breastfed infant from Daptomycin for Injection or from the underlying maternal condition.

8.4Pediatric Use This Daptomycin for Injection product is not approved for use in pediatric patients. Safety and effectiveness of daptomycin for injection in pediatric patients below the age of one year have not been established. Avoid use of Daptomycin for Injection in pediatric patients younger than one year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs [see Warnings and Precautions (5.7) and Nonclinical Toxicology (13.2) ] .

Daptomycin for Injection is not indicated in pediatric patients with renal impairment because dosage has not been established in these patients.

8.5Geriatric Use Of the 534 adult patients treated with daptomycin for injection in Phase 3 controlled clinical trials of complicated skin and skin structure infections (cSSSI), 27% were 65 years of age or older and 12% were 75 years of age or older. Of the 120 adult patients treated with daptomycin for injection in the Phase 3 controlled clinical trial of S. aureus bacteremia/endocarditis, 25% were 65 years of age or older and 16% were 75 years of age or older. In Phase 3 adult clinical trials of cSSSI and S. aureus bacteremia/endocarditis, clinical success rates were lower in patients ≥65 years of age than in patients <65 years of age.

In addition, treatment-emergent adverse events were more common in patients ≥65 years of age than in patients <65 years of age. The exposure of daptomycin was higher in healthy elderly subjects than in healthy young adult subjects. However, no adjustment of Daptomycin for Injection dosage is warranted for elderly patients with creatinine clearance (CL CR ) ≥30 mL/min [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3) ].

🆘 Overdosage 76 words ▾

10 OVERDOSAGE In the event of overdosage, supportive care is advised with maintenance of glomerular filtration. Daptomycin is cleared slowly from the body by hemodialysis (approximately 15% of the administered dose is removed over 4 hours) and by peritoneal dialysis (approximately 11% of the administered dose is removed over 48 hours). The use of high-flux dialysis membranes during 4 hours of hemodialysis may increase the percentage of dose removed compared with that removed by low-flux membranes.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Daptomycin is an antibacterial drug [see Clinical Pharmacology (12.4) ].

12.2Pharmacodynamics Based on animal models of infection, the antimicrobial activity of daptomycin appears to correlate with the AUC/MIC (area under the concentration-time curve/minimum inhibitory concentration) ratio for certain pathogens, including S. aureus . The principal pharmacokinetic/pharmacodynamic parameter best associated with clinical and microbiological cure has not been elucidated in clinical trials with daptomycin for injection.

12.3Pharmacokinetics Daptomycin for Injection Administered over a 30-Minute Period in Adults The mean and standard deviation (SD) pharmacokinetic parameters of daptomycin at steady-state following intravenous (IV) administration of daptomycin for injection over a 30-minute period at 4 to 12 mg/kg every 24h to healthy young adults are summarized in Table 7. Table 7: Mean (SD) Daptomycin Pharmacokinetic Parameters in Healthy Adult Volunteers at Steady-State Dose Daptomycin for injection was administered by IV infusion over a 30-minute period.

Doses of daptomycin for injection in excess of 6 mg/kg have not been approved. (mg/kg) Pharmacokinetic Parameters AUC 0–24 , area under the concentration-time curve from 0 to 24 hours; t 1/2 , elimination half-life; V ss , volume of distribution at steady-state; CL T , total plasma clearance; C max , maximum plasma concentration. AUC 0–24 (mcg∙h/mL) t 1/2 (h) V ss (L/kg) CL T (mL/h/kg) C max (mcg/mL) 4 (N=6) 494 (75) 8.1 (1.0) 0.096 (0.009) 8.3 (1.3) 57.8 (3.0) 6 (N=6) 632 (78) 7.9 (1.0) 0.101 (0.007) 9.1 (1.5) 93.9 (6.0) 8 (N=6) 858 (213) 8.3 (2.2) 0.101 (0.013) 9.0 (3.0) 123.3 (16.0) 10 (N=9) 1039 (178) 7.9 (0.6) 0.098 (0.017) 8.8 (2.2) 141.1 (24.0) 12 (N=9) 1277 (253) 7.7 (1.1) 0.097 (0.018) 9.0 (2.8) 183.7 (25.0) Daptomycin pharmacokinetics were generally linear and time-independent at Daptomycin for Injection doses of 4 to 12 mg/kg every 24h administered by IV infusion over a 30-minute period for up to 14 days.

Steady-state trough concentrations were achieved by the third daily dose. The mean (SD) steady-state trough concentrations attained following the administration of 4, 6, 8, 10, and 12 mg/kg every 24h were 5.9 (1.6), 6.7 (1.6), 10.3 (5.5), 12.9 (2.9), and 13.7 (5.2) mcg/mL, respectively. Daptomycin for Injection Administered over a 2-Minute Period in Adults Following IV administration of daptomycin for injection over a 2-minute period to healthy adult volunteers at doses of 4 mg/kg (N=8) and 6 mg/kg (N=12), the mean (SD) steady-state systemic exposure (AUC) values were 475 (71) and 701 (82) mcg∙h/mL, respectively.

Values for maximum plasma concentration (C max ) at the end of the 2-minute period could not be determined adequately in this study. However, using pharmacokinetic parameters from 14 healthy adult volunteers who received a single-dose of daptomycin for injection 6 mg/kg IV administered over a 30-minute period in a separate study, steady-state C max values were simulated for daptomycin for injection 4 and 6 mg/kg IV administered over a 2-minute period. The simulated mean (SD) steady-state C max values were 77.7 (8.1) and 116.6 (12.2) mcg/mL, respectively.

Distribution Daptomycin is reversibly bound to human plasma proteins, primarily to serum albumin, in a concentration-independent manner. The overall mean binding ranges from 90 to 93%. In clinical studies, mean serum protein binding in adult subjects with creatinine clearance (CL CR ) ≥30 mL/min was comparable to that observed in healthy adult subjects with normal renal function.

However, there was a trend toward decreasing serum protein binding among subjects with CL CR <30 mL/min (88%), including those receiving hemodialysis (86%) and continuous ambulatory peritoneal dialysis (CAPD) (84%). The protein binding of daptomycin in adult subjects with moderate hepatic impairment (Child-Pugh Class B) was similar to that in healthy adult subjects. The volume of di…

💬 Information for Patients ~1 min read ▾

17 PATIENT COUNSELING INFORMATION Allergic Reactions Advise patients that allergic reactions, including serious skin, kidney, lung, or other organ reactions, could occur and that these serious reactions require immediate treatment. Patients should report any previous allergic reactions to daptomycin [see Warnings and Precautions (5.1 , 5.4 , 5.5) ]. Muscle Pain or Weakness (Myopathy and Rhabdomyolysis, Peripheral Neuropathy) Advise patients to report muscle pain or weakness, especially in the forearms and lower legs, as well as tingling or numbness [see Warnings and Precautions (5.2 , 5.6) ].

Cough, Breathlessness or Fever (Eosinophilic Pneumonia) Advise patients to report any symptoms of cough, breathlessness, or fever [see Warnings and Precautions (5.3) ]. C. difficile -Associated Diarrhea (CDAD) Advise patients that diarrhea is a common problem caused by antibacterials, including Daptomycin for Injection that usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, including Daptomycin for Injection, patients can develop watery and bloody stools (with or without stomach cramps and fever), even as late as 2 or more months after having received the last dose of the antibacterial.

If this occurs, patients should contact their physician as soon as possible [see Warnings and Precautions (5.8) ] , Antibacterial Resistance Patients should be counseled that antibacterial drugs, including Daptomycin for Injection, should be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Daptomycin for Injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be administered exactly as directed.

Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Daptomycin for Injection or other antibacterial drugs in the future.
