⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Vancomycin hydrochloride capsules must be given orally for treatment of staphylococcal enterocolitis and C. difficile -associated diarrhea. Orally administered vancomycin hydrochloride capsules are not effective for other types of infections. (5.1) Clinically significant serum concentrations have been reported in some patients who have taken multiple oral doses of vancomycin hydrochloride capsules for active C. difficile -associated diarrhea.
Monitoring of serum concentrations may be appropriate in some instances. (5.2) Nephrotoxicity has occurred following oral vancomycin hydrochloride capsule therapy and can occur either during or after completion of therapy. The risk is increased in geriatric patients.
(5.3) Monitor renal function. Ototoxicity has occurred in patients receiving vancomycin hydrochloride capsules (5.4) Assessment of auditory function may be appropriate in some instances. Severe Dermatologic Reactions: Discontinue vancomycin hydrochloride capsules at the first appearance of skin rashes, mucosal lesions, or blisters.
(5.5) Prescribing vancomycin hydrochloride capsules in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug resistant bacteria. (5.6) The 125 mg strength capsules contains FD&C Yellow No. 5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons.
(5.7)
5.1Oral Use Only Vancomycin Hydrochloride Capsules for the treatment of colitis are for oral use only and are not systemically absorbed. Vancomycin Hydrochloride Capsules must be given orally for treatment of staphylococcal enterocolitis and Clostridium difficile -associated diarrhea. Orally administered Vancomycin hydrochloride capsules are not effective for other types of infections.
Parenteral administration of vancomycin is not effective for treatment of staphylococcal enterocolitis and C. difficile -associated diarrhea. If parenteral vancomycin therapy is desired, use an intravenous preparation of vancomycin and consult the package insert accompanying that preparation.
5.2Potential for Systemic Absorption Clinically significant serum concentrations have been reported in some patients who have taken multiple oral doses of Vancomycin Hydrochloride Capsules for active C. difficile -associated diarrhea. Some patients with inflammatory disorders of the intestinal mucosa also may have significant systemic absorption of vancomycin. These patients may be at risk for the development of adverse reactions associated with higher doses of Vancomycin Hydrochloride Capsules; therefore, monitoring of serum concentrations of vancomycin may be appropriate in some instances, e.g., in patients with renal insufficiency and/or colitis or in those receiving concomitant therapy with an aminoglycoside antibiotic.
5.3Nephrotoxicity Nephrotoxicity (e.g., reports of renal failure, renal impairment, blood creatinine increased) has occurred following oral Vancomycin Hydrochloride Capsules therapy in randomized controlled clinical studies, and can occur either during or after completion of therapy. The risk of nephrotoxicity is increased in patients >65 years of age (see ADVERSE REACTIONS , Clinical Trial Experience [6.1] and USE IN SPECIFIC POPULATIONS, Geriatric Use [8.5]). In patients >65 years of age, including those with normal renal function prior to treatment, renal function should be monitored during and following treatment with Vancomycin Hydrochloride Capsules to detect potential vancomycin induced nephrotoxicity.
5.4Ototoxicity Ototoxicity has occurred in patients receiving vancomycin. It may be transient or permanent. It has been reported mostly in patients who have been given excessive intravenous doses, who have an underlying hearing loss, or who are receiving concomitant therapy with another ototoxic agent, such as an aminoglycoside. Serial tests of auditory function… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse reactions (≥ 10%) were nausea (17%), abdominal pain (15%), and hypokalemia (13%). (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Avet Pharmaceuticals Inc. at 1-866-901-DRUG (3784) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to vancomycin hydrochloride in 260 adult subjects in two Phase 3 clinical trials for the treatment of diarrhea associated with C. difficile. In both trials, subjects received vancomycin hydrochloride capsules 125 mg orally four times daily.
The mean duration of treatment was 9.4 days. The median age of patients was 67, ranging between 19 and 96 years of age. Patients were predominantly Caucasian (93%) and 52% were male.
Adverse reactions occurring in ≥ 5% of vancomycin hydrochloride-treated subjects are shown in Table 1. The most common adverse reactions associated with vancomycin hydrochloride (≥ 10%) were nausea, abdominal pain, and hypokalemia. Table 1: Common (≥ 5%) Adverse Reactions a for Vancomycin Hydrochloride Reported in Clinical Trials for Treatment of Diarrhea Associated with C. difficile System/Organ Class Adverse Reaction Vancomycin Hydrochloride % (N=260) Gastrointestinal disorders Nausea 17 Abdominal pain 15 Vomiting 9 Diarrhea 9 Flatulence 8 General disorders and administration site conditions Pyrexia 9 Edema peripheral 6 Fatigue 5 Infections and infestations Urinary tract infection 8 Metabolism and nutrition disorders Hypokalemia 13 Musculoskeletal and connective tissue disorders Back pain 6 Nervous system disorders Headache 7 a Adverse reaction rates were derived from the incidence of treatment-emergent adverse events.
Nephrotoxicity (e.g., reports of renal failure, renal impairment, blood creatinine increased) occurred in 5% of subjects treated with vancomycin hydrochloride. Nephrotoxicity following vancomycin hydrochloride typically first occurred within one week after completion of treatment (median day of onset was Day 16). Nephrotoxicity following vancomycin hydrochloride occurred in 6% of subjects >65 years of age and 3% of subjects ≤65 years of age (see WARNINGS AND PRECAUTIONS, Nephrotoxicity [5.3]).
The incidences of hypokalemia, urinary tract infection, peripheral edema, insomnia, constipation, anemia, depression, vomiting, and hypotension were higher among subjects >65 years of age than in subjects ≤ 65 years of age (see USE IN SPECIFIC POPULATIONS, Geriatric Use [8.5]). Discontinuation of study drug due to adverse events occurred in 7% of subjects treated with vancomycin hydrochloride. The most common adverse events leading to discontinuation of vancomycin hydrochloride were C. difficile colitis (<1%), nausea (<1%), and vomiting (<1%).
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of vancomycin hydrochloride. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Ototoxicity : Cases of hearing loss associated with intravenously administered vancomycin have been reported.
Most of these patients had kidney dysfunction or a preexisting hearing loss or were receiving concomitant treatment with an ototoxic drug (see WARNINGS AND PRECAUTIONS, Ototoxicity [5.4]). Vertigo, dizziness and tinnitus have been reported. Skin and Subcutaneous Tissue Disorders : Severe dermatologic reactions such as toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome (SJS), drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP), and linear IgA bullous d… [Excerpted — this section continues on DailyMed.]

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS • Geriatrics: In patients >65 years of age, including those with normal renal function prior to treatment, renal function should be monitored during and following treatment with vancomycin hydrochloride capsules to detect potential vancomycin induced nephrotoxicity. (5.3) (6.1) (8.5) (14.1)
8.1Pregnancy Risk Summary Systemic absorption of vancomycin is low following oral administration of Vancomycin Hydrochloride Capsules; however, absorption may vary depending on various factors [see Clinical Pharmacology (12.3) ]. There are no available data on vancomycin use in pregnant women to assess a risk of major birth defects or miscarriage. Available published data on intravenous vancomycin use in pregnancy during the second and third trimesters have not shown an association with adverse maternal or fetal outcomes (see Data).
Vancomycin did not show adverse developmental effects when administered intravenously to pregnant rats and rabbits during organogenesis at doses less than or equal to the recommended maximum human dose (see Data). Data Human Data There are no available data on first trimester use of vancomycin in pregnant women to assess a risk of major birth defects or miscarriage. A published study evaluated hearing loss and nephrotoxicity in infants of 10 pregnant intravenous drug users treated with intravenous vancomycin for suspected or documented methicillin-resistant Staphylococcal aureus in the second or third trimester.
The comparison groups were 10 uninfected non-intravenous drug-dependent patients who received no treatment and 10 uninfected untreated intravenous drug-dependent patients. No infant in the vancomycin exposed group had abnormal sensorineural hearing at 3 months of age or nephrotoxicity. A published prospective study assessed outcomes in 55 pregnant women with a positive Group B streptococcus culture and a high-risk penicillin allergy with resistance to clindamycin or unknown sensitivity who were administered intravenous vancomycin at the time of delivery.
Vancomycin dosing ranged from the standard dose of 1 g intravenously every 12 hours to a dose of 20 mg/kg intravenously every 8 hours (maximum individual dose 2 g). No major adverse reactions were recorded either in the mothers or their newborns. None of the newborns had sensorineural hearing loss.
Neonatal renal function was not examined, but all of the newborns were discharged in good condition. Animal Data Vancomycin did not cause fetal malformation when administered intravenously during organogenesis to pregnant rats (gestation days 6 to 15) and rabbits (gestation days 6 to 18) at the equivalent recommended maximum human dose of 200 mg/kg/day to rats or 120 mg/kg/day to rabbits. No effects on fetal weight or development were seen in rats at the highest dose tested or in rabbits given 80 mg/kg/day (approximately 1 and 0.8 times the recommended maximum human dose based on body surface area).
Maternal toxicity was observed in rats (at doses 120 mg/kg and above) and rabbits (at 80 mg/kg and above).
8.2Lactation Risk Summary There are no data on the presence of vancomycin in human milk, the effects on the breastfed infant, or the effect on milk production following oral administration. Systemic absorption of vancomycin is low following oral administration of Vancomycin Hydrochloride Capsules [see Clinical Pharmacology (12.3) ]; therefore, it is unlikely to result in clinically relevant exposure in breastfeeding infants. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Vancomycin Hydrochloride Capsules and any potential adverse effects on the breastfed infant from vancomycin Hydrochloride Capsules or from the underlying maternal condition.
8.4Pediatric Use Vancomycin Hydrochloride Capsules are indicated in pediatric patients less than 18 years of age for the treatment of C. difficile associated diarrhea and enterocolitis caused by S. aureus (including meth… [Excerpted — this section continues on DailyMed.]

🧒 Pediatric Use ▾
8.4Pediatric Use Vancomycin Hydrochloride Capsules are indicated in pediatric patients less than 18 years of age for the treatment of C. difficile associated diarrhea and enterocolitis caused by S. aureus (including methicillin-resistant strains) [see Indications and Usage (1) and Dosage and Administration (2.2) ].
🧓 Geriatric Use ▾
8.5Geriatric Use In clinical trials, 54% of vancomycin hydrochloride-treated subjects were >65 years of age. Of these, 40% were between the ages of >65 and 75, and 60% were >75 years of age. Clinical studies with vancomycin hydrochloride in diarrhea associated with Clostridioides difficile have demonstrated that geriatric subjects are at increased risk of developing nephrotoxicity following treatment with oral vancomycin hydrochloride, which may occur during or after completion of therapy.
In patients >65 years of age, including those with normal renal function prior to treatment, renal function should be monitored during and following treatment with vancomycin hydrochloride to detect potential vancomycin induced nephrotoxicity (see WARNINGS AND PRECAUTIONS, Nephrotoxicity [5.3]; ADVERSE REACTIONS, Clinical Trials Experience [6.1] and CLINICAL STUDIES, Diarrhea Associated with Clostridium difficile [14.1]). Patients >65 years of age may take longer to respond to therapy compared to patients ≤65 years of age (see CLINICAL STUDIES , Diarrhea Associated with Clostridium difficile [14.1]).
Clinicians should be aware of the importance of appropriate duration of vancomycin hydrochloride treatment in patients >65 years of age and not discontinue or switch to alternative treatment prematurely.
🆘 Overdosage ▾
10 OVERDOSAGE Supportive care is advised, with maintenance of glomerular filtration. Vancomycin is poorly removed by dialysis. Hemofiltration and hemoperfusion with polysulfone resin have been reported to result in increased vancomycin clearance.
To obtain current information about the treatment of overdose, contact a certified Poison Control Center (1-800-222-1222 or www.poison.org). In managing overdosage, consider the possibility of multiple drug overdoses, interaction among drugs, and unusual drug kinetics.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Vancomycin is an antibacterial drug (see Microbiology [12.4]).
12.3Pharmacokinetics Vancomycin is poorly absorbed after oral administration. During multiple dosing of 250 mg every 8 hours for 7 doses, fecal concentrations of vancomycin in volunteers exceeded 100 mg/kg in the majority of samples. No blood concentrations were detected and urinary recovery did not exceed 0.76%.
In anephric subjects with no inflammatory bowel disease who received vancomycin oral solution 2 g for 16 days, blood concentrations of vancomycin were less than or equal to 0.66 ug/mL in 2 of 5 subjects. No measurable blood concentrations were attained in the other 3 subjects. Following doses of 2 g daily, concentrations of drug were >3100 mg/kg in the feces and <1 mcg/mL in the serum of subjects with normal renal function who had C. difficile associated diarrhea.
After multiple-dose oral administration of vancomycin, measurable serum concentrations may occur in patients with active C. difficile- associated diarrhea, and, in the presence of renal impairment, the possibility of accumulation exists. It should be noted that the total systemic and renal clearances of vancomycin are reduced in the elderly (see Use in Specific Population [8.5] ).
12.4Microbiology Mechanism of action The bactericidal action of vancomycin against Staphylococcus aureus and the vegetative cells of Clostridioides difficile results primarily from inhibition of cell-wall biosynthesis. In addition, vancomycin alters bacterial-cell-membrane permeability and RNA synthesis. Mechanism of resistance Staphylococcus aureus: S. aureus isolates with vancomycin minimal inhibitory concentrations (MICs) as high as 1024 mcg/mL have been reported.
The exact mechanism of this resistance is not clear but is believed to be due to cell wall thickening and potentially the transfer of genetic material. Clostridiumum difficile: Isolates of C. difficile generally have vancomycin MICs of <1 mcg/mL, however vancomycin MICs ranging from 4 mcg/mL to 16 mcg/mL have been reported. The mechanism which mediates C. difficile's decreased susceptibility to vancomycin has not been fully elucidated.
Vancomycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections [see Indications and Usage (1) ]. Gram-positive bacteria: Staphylococcus aureus (including methicillin-resistant isolates) associated with enterocolitis . Anaerobic gram-positive bacteria: Clostridium difficile isolates associated with C. difficile associated diarrhea.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Severe Dermatologic Reactions Advise patients about the signs and symptoms of serious skin manifestations. Instruct patients to stop taking Vancomycin Hydrochloride Capsules immediately and promptly seek medical attention at the first signs or symptoms of skin rash, mucosal lesions or blisters [see Warnings and Precautions (5.5) ]. Antibacterial Resistance Patients should be counseled that antibacterial drugs including Vancomycin Hydrochloride should only be used to treat bacterial infections.
They do not treat viral infections (e.g., the common cold). When Vancomycin Hydrochloride 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 taken 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 Vancomycin Hydrochloride or other antibacterial drugs in the future.

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Vancomycin is poorly absorbed after oral administration. During multiple dosing of 250 mg every 8 hours for 7 doses, fecal concentrations of vancomycin in volunteers exceeded 100 mg/kg in the majority of samples. No blood concentrations were detected and urinary recovery did not exceed 0.76%.
In anephric subjects with no inflammatory bowel disease who received vancomycin oral solution 2 g for 16 days, blood concentrations of vancomycin were less than or equal to 0.66 ug/mL in 2 of 5 subjects. No measurable blood concentrations were attained in the other 3 subjects. Following doses of 2 g daily, concentrations of drug were >3100 mg/kg in the feces and <1 mcg/mL in the serum of subjects with normal renal function who had C. difficile associated diarrhea.
After multiple-dose oral administration of vancomycin, measurable serum concentrations may occur in patients with active C. difficile- associated diarrhea, and, in the presence of renal impairment, the possibility of accumulation exists. It should be noted that the total systemic and renal clearances of vancomycin are reduced in the elderly (see Use in Specific Population [8.5] ).

14 CLINICAL STUDIES
14.1Diarrhea Associated with Clostridium difficile In two trials, Vancomycin Hydrochloride Capsules 125 mg orally four times daily for 10 days was evaluated in 266 adult subjects with C. difficile -associated diarrhea (CDAD). Enrolled subjects were 18 years of age or older and received no more than 48 hours of treatment with oral vancomycin hydrochloride or oral/intravenous metronidazole in the 5 days preceding enrollment. CDAD was defined as ≥3 loose or watery bowel movements within the 24 hours preceding enrollment, and the presence of either C. difficile toxin A or B, or pseudomembranes on endoscopy within the 72 hours preceding enrollment.
Subjects with fulminant C. difficile disease, sepsis with hypotension, ileus, peritoneal signs or severe hepatic disease were excluded. Efficacy analyses were performed on the Full Analysis Set (FAS), which included randomized subjects who received at least one dose of vancomycin hydrochloride and had any post-dosing investigator evaluation data (N=259; 134 in Trial 1 and 125 in Trial 2). The demographic profile and baseline CDAD characteristics of enrolled subjects were similar in the two trials.
Vancomycin Hydrochloride-treated subjects had a median age of 67 years, were mainly white (93%), and male (52%). CDAD was classified as severe (defined as 10 or more unformed bowel movements per day or WBC ≥15000/mm 3 ) in 25% of subjects, and 47% were previously treated for CDAD. Efficacy was assessed by using clinical success, defined as diarrhea resolution and the absence of severe abdominal discomfort due to CDAD, on Day 10.
An additional efficacy endpoint was the time to resolution of diarrhea, defined as the beginning of diarrhea resolution that was sustained through the end of the prescribed active treatment period. The results for clinical success for vancomycin hydrochloride-treated subjects in both trials are shown in Table 2. Table 2: Clinical Success Rates (Full Analysis Set) Clinical Success Rate 95% Confidence Interval Vancomycin Hydrochloride % (N) Trial 1 81.3 (134) (74.4, 88.3) Trial 2 80.8 (125) (73.5, 88.1) The median time to resolution of diarrhea was 5 days and 4 days in Trial 1 and Trial 2, respectively.
For subjects older than 65 years of age, the median time to resolution was 6 days and 4 days in Trial 1 and Trial 2, respectively. In subjects with diarrhea resolution at end-of-treatment with Vancomycin Hydrochloride Capsules, recurrence of CDAD during the following four weeks occurred in 25 of 107 (23%) and 18 of 102 (18%) in Trial 1 and Trial 2, respectively. Restriction Endonuclease Analysis (REA) was used to identify C. difficile baseline isolates in the BI group.
In Trial 1, the Vancomycin Hydrochloride-treated subjects were classified at baseline as follows 31 (23%) with BI strain, 69 (52%) with non-BI strain, and 34 (25%) with unknown strain. Clinical success rates were 87% for BI strain, 81% for non-BI strain, and 76% for unknown strain. In subjects with diarrhea resolution at end-of-treatment with vancomycin hydrochloride, recurrence of CDAD during the following four weeks occurred in 7 of 26 subjects with BI strain, 12 of 56 subjects with non-BI strain, and 6 of 25 subjects with unknown strain.
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term carcinogenesis studies in animals have been conducted. At concentrations up to 1000 mcg/mL, vancomycin had no mutagenic effect in vitro in the mouse lymphoma forward mutation assay or the primary rat hepatocyte unscheduled DNA synthesis assay. The concentrations tested in vitro were above the peak plasma vancomycin concentrations of 20 to 40 mcg/mL usually achieved in humans after slow infusion of the maximum recommended dose of 1 g.
Vancomycin had no mutagenic effect in vivo in the Chinese hamster sister chromatid exchange assay (400 mg/kg IP) or the mouse micronucleus assay (800 mg/kg IP). No definitive fertility studies have been conducted.
