The Pharmacist’s Take By · Clinical pharmacist · Written

Amoxicillin is a penicillin-type antibiotic that kills bacteria by blocking how they build their cell walls. It is used for certain ear, nose, throat, lung, urinary and skin infections and, alongside other medicines, for H. pylori ulcers in adults; on the market since about 1974 and available as a generic, it is a familiar first choice. Most people tolerate it well, and loose stools, nausea or a mild rash are what they usually notice. Watch for a serious allergic reaction (trouble breathing, swelling, severe hives), which is more likely after a past penicillin reaction, so stop it and get emergency help. Also call your prescriber if a rash spreads or diarrhea turns watery or bloody, even months later.

Clinical pearls

  • Take it at the start of a meal to ease stomach upset, and finish the course even after you feel better.
  • If mononucleosis is a possibility, say so first, since amoxicillin very often causes a rash in people with mono.
  • If you take an oral blood thinner such as warfarin, your INR (a clotting test) may need checking, since amoxicillin can strengthen its effect.
  • Amoxicillin may make combined estrogen-progesterone birth control less effective, so consider backup contraception while taking it.

What Amoxicillin is used for

▾

Amoxicillin treats infections caused by susceptible, beta-lactamase-negative bacteria. The supported uses are:

  • Infections of the ear, nose and throat
  • Infections of the genitourinary tract
  • Infections of the skin and skin structure
  • Infections of the lower respiratory tract
  • Adults only: H. pylori infection and duodenal ulcer disease, as triple therapy with clarithromycin and lansoprazole
  • Adults only: H. pylori dual therapy with lansoprazole, for people who are allergic or intolerant to clarithromycin or whose bacteria are resistant to it (Amoxil tablets and several amoxicillin labels)
  • Acute uncomplicated gonorrhea (Amoxil and amoxicillin for oral suspension labels only), and only when the bacteria are known to be susceptible

How Amoxicillin works

▾

Amoxicillin is a penicillin-type antibacterial. It kills susceptible bacteria while they are multiplying by stopping them from building their cell walls.

Resistance happens mainly when bacteria make beta-lactamase enzymes that break amoxicillin apart. That is why it is only indicated for susceptible, beta-lactamase-negative bacteria.

Amoxicillin dosage

▾

Amoxicillin is taken by mouth, usually every 8 to 12 hours. Your dose depends on the infection, its severity, and (for children) body weight.

  • Take it at the start of a meal to reduce stomach upset.
  • Keep taking it for at least 48 to 72 hours after symptoms resolve, and at least 10 days for Streptococcus pyogenes infections.
  • People with severe kidney problems may need a lower dose.
  • H. pylori treatment is given with other medicines, usually for 14 days.

Follow your prescriber’s directions and the label.

Amoxicillin side effects

▾

The most common side effects in clinical trials were:

Common side effects

  • Diarrhea
  • Rash
  • Nausea
  • Vomiting
  • Headache (when used in H. pylori combination therapy)
  • Taste changes (when used in H. pylori triple therapy)

When to get medical help

  • Seek emergency help for signs of a serious allergic reaction (anaphylaxis), such as trouble breathing, swelling or severe hives.
  • Stop the medicine and call your doctor if a skin rash spreads or worsens, since severe skin reactions can occur.
  • Call your doctor if you have severe vomiting 1 to 4 hours after a dose, especially in a child, as it may be drug-induced enterocolitis syndrome (DIES).
  • Call your doctor if you have watery or bloody diarrhea, which can start even more than 2 months after treatment.
  • Report yellowing of the skin or eyes, unusual bruising or bleeding, confusion or seizures.

Amoxicillin warnings and precautions

▾
  • Serious allergic reactions: Anaphylaxis can be fatal and is more likely in people with a penicillin allergy history. Stop the drug if it occurs.
  • Severe skin reactions: Includes SJS, TEN, DRESS and AGEP. Stop if a rash progresses.
  • DIES: Protracted vomiting 1 to 4 hours after a dose, mostly in children under 18.
  • C. difficile diarrhea: Can range from mild to fatal and can appear over 2 months after treatment.
  • Mononucleosis: A high percentage develop a rash, so amoxicillin should not be given.
  • Resistance: Use without a bacterial infection offers no benefit and promotes resistant bacteria.

Amoxicillin interactions

▾

These are the key interactions:

  • Probenecid: slows amoxicillin clearance, raising blood levels.
  • Oral anticoagulants: INR may rise, so monitoring is needed.
  • Allopurinol: increases the rate of rash.
  • Combined oral contraceptives: may be less effective.
  • Chloramphenicol, macrolides, sulfonamides, tetracyclines: may interfere with amoxicillin’s killing effect.
  • Urine glucose tests: some tests may give false positives.

Interactions listed in the FDA-approved label

From the Amoxicillin prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.

  • Probenecid: Probenecid decreases renal tubular secretion of amoxicillin, which may result in increased and prolonged blood levels of amoxicillin.
  • Oral anticoagulants: Abnormal prolongation of prothrombin time (increased INR) has been reported in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken; adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation.
  • Allopurinol: Concurrent use increases the incidence of rashes compared to amoxicillin alone.
  • Oral contraceptives: Amoxicillin may affect the gut flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives.
  • Other antibacterials (chloramphenicol, macrolides, sulfonamides, tetracyclines): May interfere with the bactericidal effects of penicillin, demonstrated in vitro; clinical significance is not well documented.
  • Urine glucose tests (CLINITEST, Benedict's Solution, Fehling's Solution): High urine concentrations of ampicillin may cause false-positive urine glucose results, and this may also occur with amoxicillin. Use glucose tests based on enzymatic glucose oxidase reactions (such as CLINISTIX).

7 DRUG INTERACTIONS • Probenicid decreases renal tubular secretion of amoxicillin which may result in increased blood levels of amoxicillin. ( 7.1 ) • Concomitant use of amoxicillin and oral anticoagulants may increase the prolongation of prothrombin time. ( 7.2 ) • Coadministration with allopurinol increases the risk of rash. ( 7.3 ) • Amoxicillin may reduce the efficacy of oral contraceptives. ( 7.4 ) 7.1 Probenecid Probenecid decreases the renal tubular secretion of amoxicillin. Concurrent use of amoxicillin and probenecid may result in increased and prolonged blood levels of amoxicillin. 7.2 Oral Anticoagulants Abnormal prolongation of prothrombin time (increased international normalized ratio [INR]) has been reported in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation. 7.3 Allopurinol The concurrent administration of allopurinol and amoxicillin increases the incidence of rashes in patients receiving both drugs as compared to patients receiving amoxicillin alone. It is not known whether this potentiation of amoxicillin rashes is due to allopurinol or the hyperuricemia present in these patients. 7.4 Oral Contraceptives Amoxicillin may affect the gut flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives. 7.5 Other Antibacterials Chloramphenicol, macrolides, sulfonamides, and tetracyclines may interfere with the bactericidal effects of penicillin. This has been demonstrated in vitro ; however, the clinical significance of this interaction is notwell documented.

Before taking Amoxicillin

▾
  • Do not use it after a serious allergic reaction to amoxicillin, penicillins or cephalosporins.
  • Tell your prescriber about past reactions to penicillins, cephalosporins or other allergens.
  • Pregnancy: use only if clearly needed.
  • Breastfeeding: amoxicillin passes into milk and may sensitize the infant.
  • Children: infants 3 months or younger need modified dosing. H. pylori use has not been established in children.
  • Older adults: kidney function may be lower, so dose selection and monitoring matter.
  • Kidney impairment: dose adjustment is usually needed in severe impairment.
  • Phenylketonuria: chewable tablets contain phenylalanine.

Amoxicillin overdose

▾

Large overdoses can cause kidney problems, including crystals in the urine (crystalluria) and, rarely, kidney inflammation or kidney failure. The label says to stop amoxicillin, treat symptoms, and keep up good fluid intake. Kidney problems appear reversible once the drug is stopped, and hemodialysis can remove amoxicillin.

What Amoxicillin does in the body

▾

Amoxicillin has bactericidal (bacteria-killing) action against susceptible bacteria that are actively multiplying. It works by inhibiting cell wall synthesis. It is active against most isolates of several bacteria, including Streptococcus, Staphylococcus, E. coli, H. influenzae, Proteus mirabilis, E. faecalis, N. gonorrhoeae and H. pylori.

How your body processes Amoxicillin

▾

Amoxicillin is stable in stomach acid and is absorbed rapidly after you swallow it. Blood levels peak about 1 to 2 hours after a dose. It spreads into most body tissues and fluids, but not into brain or spinal fluid unless the meninges are inflamed.

Its half-life is about 61 minutes. About 60% of a dose leaves in urine within 6 to 8 hours, mostly unchanged. Probenecid can delay this.

How to store Amoxicillin

▾

Store at or below 25° C (77° F) . Dispense in a tight container.

Amoxicillin: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Amoxicillin — the kind of thing our pharmacy team would talk through with you at the counter.

What is amoxicillin treating?

▾
It is an antibiotic for infections caused by susceptible bacteria. These include ear, nose and throat, chest, urinary tract and skin infections. In adults it is also used with other medicines for H. pylori and duodenal ulcer disease. It won’t help with viral illnesses like colds or flu.

How should I take it?

▾
Take it by mouth at the start of a meal, which helps limit stomach upset. Follow the schedule your prescriber gave you. Finish the full course even if you feel better, because stopping early can let the infection return.

What side effects are normal, and when should I call?

▾
Diarrhea, nausea, vomiting and mild rash are the most common. Call your doctor if a rash spreads, if you have severe or bloody diarrhea, or if your child has repeated vomiting an hour or more after a dose. Get emergency help for trouble breathing or swelling of the face or throat.

I’m allergic to penicillin. Can I take this?

▾
Tell me and your prescriber first. Amoxicillin should not be used after a serious allergic reaction to penicillins or cephalosporins. Reactions can be severe and even fatal.

Does it interact with my other medicines?

▾
It can. Probenecid raises amoxicillin levels, allopurinol increases rash risk, and blood thinners taken by mouth may need extra INR checks. It may also make combined birth control pills less effective, so ask about backup protection.

Is it safe in pregnancy or while breastfeeding?

▾
In pregnancy, it should be used only if clearly needed. Animal studies showed no harm, but there are no good studies in pregnant women. It passes into breast milk and may sensitize a baby, so talk with your doctor if you are nursing.

Is Amoxicillin available over the counter?

▾
No. Amoxicillin is a prescription medicine: every Amoxicillin product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Amoxicillin first available?

▾
The earliest FDA record we hold for Amoxicillin is from 1974: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Amoxicillin was first used.

Who makes Amoxicillin?

▾
31 companies currently list Amoxicillin products in the FDA's NDC Directory, including A-S Medication Solutions, NuCare Pharmaceuticals,Inc., Proficient Rx LP. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

(It’s also why a refill can look different — a new shape, color, or box — even though it contains the same medication.)

Amoxicillin side effects reported to the FDA (FAERS)

After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Amoxicillin — a signal of what to watch for, not proof the drug caused it.

The effects most often named in FDA reports that mention Amoxicillin are diarrhoea, drug hypersensitivity, nausea; about 79% of the reports were classed as serious. These are voluntary reports, so they show what people report, not how often it happens.

Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Amoxicillin in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

Amoxicillin recall history

A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

The FDA’s enforcement reports list 2 Amoxicillin recalls since July 2021, covering 3 product listings. None of them is still listed as ongoing. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.

💵 What Amoxicillin costs pharmacies (NADAC benchmark)

The national average invoice price pharmacies pay for the drug itself, from CMS's NADAC survey (data as of Sep 30, 2026). This is a supply-cost benchmark — not a retail price and not what you'd pay at the counter.

Capsule · Oral 500 mg $0.079 per capsule NDC details & price history
Capsule · Oral 250 mg $0.069 per capsule NDC details & price history
Powder, For Suspension · Oral 400 mg/5 mL $0.034–$0.044 per mL NDC details & price history

Why show this? Your out-of-pocket cost depends on insurance, pharmacy markup, and discounts — but the acquisition benchmark tells you whether the medication itself is inexpensive or costly, which strengths cost more per dose, and whether a cash-price quote is in a reasonable range. Each row links to the NDC-level record with its full price history.
