How to Order	Available in the USA with a valid prescription through licensed online and local pharmacies

Amoxicilina (known internationally as amoxicillin) is one of the most commonly prescribed oral antibiotics in the United States. As a semi-synthetic penicillin-class beta-lactam, it has been a mainstay of outpatient therapy for decades due to its favorable safety profile, broad utility against many community-acquired bacterial pathogens, and availability in multiple convenient formulations for adults and children. In the USA, amoxicillin is prescription-only; patients can obtain it from a licensed pharmacy after a clinician determines it is appropriate. Common strengths include 250 mg, 500 mg, and 875 mg tablets or capsules, as well as pediatric suspensions measured in mg/mL to accommodate weight-based dosing.

Because the antibiotic must be matched to the infection and the patient’s medical history, US regulations require a valid prescription to ensure safe, effective, and responsible use. Our partner pharmacies work with US-licensed clinicians and pharmacists to help you obtain amoxicillin when medically indicated. Whether you are managing strep throat, acute otitis media, sinusitis, a dental infection, or part of a combination therapy for H. pylori, amoxicillin is often an accessible, cost-effective choice. This page explains its uses, dosing, safety considerations, and how to order legally from within the United States.

Amoxicillin cost in the USA

Generic amoxicillin is widely available in the US, and the price is typically modest compared to many newer antibiotics. The final cost can vary based on strength, quantity, formulation (tablet, capsule, chewable, or suspension), pharmacy pricing, and whether you use insurance, manufacturer programs, or discount cards. In many US pharmacies, a typical 10-day course for an adult (for example, 500 mg taken two or three times daily) can be very affordable when filled as a generic.

For pediatric patients, pricing depends on the required mg/kg/day and the volume of oral suspension dispensed. Because children’s doses are weight-based, the total volume can differ, thereby affecting cost. Pharmacies often provide flavoring for suspensions at little or no additional cost to help with adherence.

If you are paying cash, consider price comparison tools and discount programs that many US pharmacies accept. Patients using insurance should verify formulary coverage and co-pay amounts. Extended-release formulations or specific brand names, such as Moxatag (amoxicillin extended-release), may be more expensive than standard generics. Our partner network can help you price your prescription, identify savings, and arrange secure shipping where permitted by law.

Where can I buy amoxicillin in the USA?

In the United States, amoxicillin is available by prescription only. You can purchase it at local brick-and-mortar pharmacies or through licensed online pharmacies once a US-licensed prescriber issues a valid prescription. Many telehealth services can evaluate your symptoms and medical history, determine whether an antibiotic is appropriate, and—if indicated—send a prescription directly to your chosen pharmacy for fulfillment and delivery.

Responsible antibiotic use is essential to protect your health and reduce antimicrobial resistance. Amoxicillin should not be used for viral infections such as the common cold or most cases of acute bronchitis. When antibiotics are not indicated, your clinician will recommend supportive care or alternative treatments. If an antibiotic is necessary, follow the prescribed dose, frequency, and duration without skipping doses or stopping early, even if you feel better.

Our partner pharmacies provide discreet packaging, transparent pricing, and customer support. They ship to most US states in compliance with federal and state laws. If you prefer to pick up your prescription locally, we can transfer the prescription to a nearby pharmacy upon request.

Amoxicillin USA: accessibility and forms

Amoxicillin comes in multiple oral dosage forms to meet different patient needs:

• Tablets or capsules: commonly 250 mg, 500 mg, and 875 mg
• Chewable tablets: useful for patients who have difficulty swallowing
• Extended-release tablets: for once-daily dosing in specific conditions
• Oral suspension: measured in mg/mL, used frequently in pediatrics for precise, weight-based dosing

Discuss formulation preferences with your prescriber or pharmacist. For example, extended-release tablets must be swallowed whole and taken with food, while standard tablets and capsules can be taken with or without food unless your clinician advises otherwise.

What is amoxicillin?

Amoxicillin is a beta-lactam antibiotic in the penicillin family. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), which ultimately disrupts peptidoglycan cross-linking and leads to bacterial cell lysis. Compared with older penicillins, amoxicillin offers enhanced activity against certain gram-negative organisms while maintaining robust activity against many gram-positive species, particularly Streptococcus. It is not active against all bacteria, however; susceptibility testing or local resistance patterns may influence antibiotic selection.

Amoxicillin is commonly paired with a beta-lactamase inhibitor (clavulanate) to broaden coverage against beta-lactamase–producing organisms. This combination is known as amoxicillin/clavulanate (brand example: Augmentin). When the infection involves organisms likely to produce beta-lactamase—such as some strains of Haemophilus influenzae or Moraxella catarrhalis—your clinician may select the combination product instead of amoxicillin alone.

Amoxicillin is not effective against viral illnesses and should not be used for conditions like influenza, the common cold, or most viral sore throats. Using antibiotics when they are not indicated can cause side effects without benefit and contributes to antibiotic resistance.

Common uses for amoxicillin

Clinicians prescribe amoxicillin for a number of FDA-labeled and guideline-supported indications when the causative organism is susceptible:

• Ear, nose, and throat infections: including acute otitis media (AOM), sinusitis, and strep pharyngitis (strep throat)
• Lower respiratory tract infections: for select cases, often depending on local resistance patterns and patient factors
• Skin and soft tissue infections: for susceptible organisms
• Uncomplicated urinary tract infections: if the pathogen is susceptible; other agents are often preferred for empiric therapy
• Dental infections: such as odontogenic infections when first-line therapy is appropriate
• H. pylori eradication: as part of combination therapy with a proton pump inhibitor and another antibiotic
• Lyme disease (early localized): amoxicillin is a recommended option for certain patients
• Endocarditis prophylaxis for dental procedures: in high-risk cardiac patients, according to current guidelines

Choice of therapy depends on infection severity, patient age, allergies, local resistance patterns, and comorbidities. Amoxicillin/clavulanate may be preferred in some sinusitis cases or bite wounds due to broader coverage.

Amoxicillin dosing for adults

Dosing must be individualized by a clinician. Typical adult regimens include:

• Strep throat (pharyngitis/tonsillitis caused by Streptococcus pyogenes): 500 mg twice daily or 250 mg three times daily for 10 days
• Acute otitis media or acute sinusitis: 500 mg three times daily or 875 mg twice daily (duration varies from 5 to 10 days based on severity and guidelines; amoxicillin/clavulanate may be preferred for sinusitis in many adults)
• Lower respiratory infections (select cases): 500 mg three times daily or 875 mg twice daily, as guided by the clinician
• Skin/soft tissue infections (susceptible organisms): 500 mg three times daily or 875 mg twice daily
• Uncomplicated UTI (if susceptible): 500 mg every 12 hours for 5–7 days (other agents are commonly first-line)
• H. pylori eradication (triple therapy example): amoxicillin 1,000 mg twice daily + clarithromycin 500 mg twice daily + PPI twice daily for 14 days; follow clinician guidance
• Endocarditis prophylaxis (dental procedures in high-risk patients): 2 g once, 30–60 minutes before the procedure
• Early localized Lyme disease: 500 mg three times daily for 14–21 days (as recommended by guidelines and prescriber discretion)

Patients with reduced kidney function may need dosage adjustments or avoidance of higher-strength tablets such as 875 mg. Always adhere to your clinician’s instructions and do not self-dose.

Pediatric dosing

Children are typically dosed based on body weight:

• Acute otitis media: 80–90 mg/kg/day divided twice daily (or 45 mg/kg/day divided twice daily for milder cases), max per dose and total daily dose per prescriber
• Strep throat: 50 mg/kg once daily (max 1,000 mg/day) or 25 mg/kg twice daily for 10 days
• Sinusitis and other infections: dosing depends on severity and local resistance; follow pediatric specialist guidance

Use an accurate oral syringe or dosing device for liquid medications. Pharmacists can provide counseling on measuring and administering the suspension.

How to take amoxicillin

Follow your prescription label exactly. General tips include:

• Standard immediate-release tablets/capsules: may be taken with or without food; taking with food can reduce stomach upset for some patients
• Extended-release tablets: take with food, swallow whole—do not crush, split, or chew
• Oral suspension: shake well before each use; measure with a marked oral syringe or dosing spoon
• Hydration: drink a full glass of water with each dose unless your clinician advises otherwise
• Adherence: take doses at evenly spaced intervals; complete the entire course even if you feel better

If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. Do not double up to make up for a missed dose. If you vomit shortly after a dose, consult your clinician or pharmacist for advice.

Storage and handling

Store tablets and capsules at room temperature away from excessive heat and moisture. For reconstituted oral suspension, your pharmacy label will indicate whether refrigeration is recommended; many amoxicillin suspensions are stable for up to 14 days and may be refrigerated to improve taste. Keep all medicines out of reach of children and pets. Do not use expired antibiotics. Dispose of unused medication according to local guidance or pharmacy take-back programs.

Safety profile and possible side effects

Amoxicillin is generally well tolerated. Most side effects are mild and temporary. However, serious reactions can occur, especially in patients with a penicillin allergy.

Common side effects:

• Nausea, vomiting, or diarrhea
• Stomach discomfort
• Mild skin rash
• Headache
• Vaginal yeast infection or oral thrush due to disruption of normal flora

Serious side effects (seek medical attention immediately):

• Severe allergic reaction/anaphylaxis: facial or throat swelling, hives, difficulty breathing, dizziness
• Severe skin reactions: blistering, peeling rash
• Persistent or bloody diarrhea: possible sign of Clostridioides difficile–associated diarrhea
• Yellowing of the skin or eyes, dark urine, or severe fatigue: possible liver-related issues (rare)

Some patients with mononucleosis (caused by Epstein-Barr virus) who take amoxicillin may develop a non-allergic rash. This rash typically appears several days after starting the antibiotic and is not the same as a true penicillin allergy. Nevertheless, inform your clinician if any rash develops so they can assess its nature and guide future antibiotic choices.

Who should not take amoxicillin?

Do not use amoxicillin if you have a known hypersensitivity to amoxicillin, any penicillin antibiotic, or any ingredient in the product. Cross-reactivity can occur among beta-lactam antibiotics such as cephalosporins; your clinician will assess your allergy history carefully.

Patients with severe kidney impairment may require dose adjustments or alternative therapy. Always tell your prescriber about your full medical history, including kidney or liver disease, severe asthma, or prior antibiotic-associated colitis.

Pregnancy and breastfeeding

Amoxicillin has been widely used during pregnancy and is generally considered a preferred option when an antibiotic is clinically indicated. Nonetheless, all medication use during pregnancy should be guided by a clinician who weighs risks and benefits for the specific condition.

Amoxicillin is excreted in breast milk in small amounts and is typically considered compatible with breastfeeding. Monitor infants for changes in gut flora (e.g., diarrhea or thrush). Discuss treatment plans with your obstetrician or pediatrician.

Drug interactions

Always inform your prescriber and pharmacist of all medicines, supplements, and herbal products you take. Potential interactions include:

• Warfarin and other anticoagulants: antibiotics may affect INR; monitoring and dose adjustments may be required
• Methotrexate: penicillins can reduce methotrexate clearance; monitor for toxicity
• Allopurinol: co-administration may increase the risk of skin rash
• Probenecid: can increase amoxicillin levels by reducing renal excretion
• Oral contraceptives: antibiotics may theoretically reduce effectiveness; consider backup contraception if advised by your clinician
• Live attenuated oral typhoid vaccine: antibiotics may reduce vaccine effectiveness; separate timing per guidance

This list is not exhaustive. Your clinician may adjust therapy or increase monitoring to safely manage interactions.

Amoxicillin vs. amoxicillin/clavulanate

Amoxicillin/clavulanate combines amoxicillin with clavulanic acid, a beta-lactamase inhibitor that expands coverage against organisms producing beta-lactamase enzymes. Clinicians may choose amoxicillin/clavulanate for:

• Acute bacterial sinusitis (many adult cases)
• Bite wounds (human or animal)
• Recurrent otitis media or suspected beta-lactamase–producing organisms
• Certain lower respiratory tract infections

While the combination product offers broader coverage, it can be associated with more gastrointestinal side effects. When narrower coverage is sufficient, amoxicillin alone remains an effective and well-tolerated option.

Antibiotic stewardship and resistance

Antibiotic stewardship is a critical public health priority in the United States. Taking amoxicillin only when prescribed, at the correct dose and duration, helps maintain its effectiveness and reduces the development of resistant bacteria. Do not share antibiotics with others, save leftover doses for later use, or pressure your clinician to prescribe an antibiotic for viral conditions. If your symptoms persist or worsen, contact your clinician for reassessment rather than self-adjusting therapy.

Condition-specific guidance

Strep throat (streptococcal pharyngitis)

Amoxicillin is a common first-line treatment for strep throat due to its effectiveness and tolerability. Adults often take 500 mg twice daily for 10 days, while children receive weight-based dosing. Completing the full course helps prevent complications such as rheumatic fever.

Acute otitis media (ear infection)

In children, high-dose amoxicillin (80–90 mg/kg/day divided twice daily) is often recommended for acute otitis media to overcome potential resistance. Your pediatrician may adjust dosing based on the child’s age, symptom severity, and vaccination status. Follow-up is important if fever or ear pain persists.

Sinusitis

Acute bacterial rhinosinusitis can be difficult to distinguish from a viral infection. Many cases improve without antibiotics. When bacterial sinusitis is suspected, guidelines often prefer amoxicillin/clavulanate in adults. However, amoxicillin alone may be used in select situations per clinician judgment, particularly when risk of beta-lactamase–producing organisms is low.

Lower respiratory infections

Amoxicillin may be used for certain lower respiratory tract infections depending on the likely pathogens and local resistance patterns. In many adult patients, alternative agents or combination therapy may be chosen based on severity and comorbidities. Always follow clinician guidance.

Urinary tract infections

While amoxicillin can treat UTIs caused by susceptible organisms, empirical use is often limited due to resistance among common uropathogens. Your clinician may choose a different first-line agent pending culture and sensitivity results. If culture indicates susceptibility, amoxicillin can be an appropriate option.

Dental infections

Amoxicillin is commonly used for odontogenic infections. A typical adult regimen is 500 mg three times daily for 3–7 days, with reassessment by a dentist. For patients allergic to penicillin, clinicians will choose an appropriate alternative. Endocarditis prophylaxis before certain dental procedures in high-risk patients typically involves a single 2 g dose taken 30–60 minutes prior (pediatric dose: 50 mg/kg). Always follow your dentist’s and cardiologist’s recommendations.

H. pylori eradication

Amoxicillin is part of several combination regimens for H. pylori–associated peptic ulcer disease. One example of triple therapy is amoxicillin 1,000 mg twice daily with clarithromycin 500 mg twice daily and a proton pump inhibitor twice daily for 14 days. Quadruple therapy alternatives may be used in areas of high resistance or prior treatment failure. Your gastroenterologist will select an appropriate regimen and confirm eradication when needed.

Early Lyme disease

For early localized Lyme disease (e.g., erythema migrans rash) in patients who cannot take doxycycline or for whom amoxicillin is preferred, a common adult regimen is 500 mg three times daily for 14–21 days. Children receive weight-based dosing. Monitoring for symptom improvement and follow-up are important parts of care.

Practical pharmacist tips

Maximize the benefits of your treatment with these pharmacist-recommended practices:

• Take doses on schedule and complete the entire course
• For liquid suspension, shake well and measure with an oral syringe
• If stomach upset occurs, consider taking doses with a light snack (unless using extended-release, which should be taken with food by design)
• Call your clinician if you develop severe diarrhea, rash, or signs of an allergic reaction
• Keep track of all current medications to screen for interactions
• Discuss probiotic use with your clinician if you’re prone to antibiotic-associated diarrhea

Warnings and precautions

Stop taking amoxicillin and seek urgent medical attention if you experience difficulty breathing, wheezing, swelling of the lips or throat, or severe hives. These may be signs of a serious allergic reaction. Report persistent diarrhea, bloody stools, or severe abdominal pain to your clinician, as these may suggest C. difficile–associated diarrhea. Patients with renal impairment may require dose modifications; extended-release tablets may not be appropriate for reduced kidney function.

Amoxicillin side effects: what to watch for

Most side effects are mild and manageable. Notify your clinician if they are severe or persistent. Remember that any new symptom after starting an antibiotic warrants attention, especially if you have a history of drug allergies. If your symptoms do not improve within a few days, or if they worsen, contact your prescriber for reassessment.

Reporting side effects

 If you experience any adverse effects, speak with your healthcare provider or pharmacist. In the USA, you may also report side effects to the FDA’s MedWatch program.

Interaction of amoxicillin with other medicines

 Drug interactions can change how your medications work or increase your risk for serious side effects. Keep an updated list of all prescription drugs, over-the-counter medicines, vitamins, and herbal products you use, and share it with your clinician and pharmacist. They can help you avoid or manage interactions by adjusting doses, monitoring therapy closely, or choosing alternative treatments.

Examples of medicines that may interact with amoxicillin include:

• Warfarin and other anticoagulants (may affect INR)
• Methotrexate (risk of increased levels)
• Allopurinol (higher chance of rash)
• Probenecid (increases amoxicillin levels)
• Combined oral contraceptives (consider backup contraception if advised)

Not all interactions are listed here. Consult your healthcare provider for personalized guidance.

Our specialists’ recommendations for US patients

 If your clinician has determined that an antibiotic is appropriate, amoxicillin is often a good first choice for susceptible community-acquired infections. Be sure to use antibiotics only when necessary and as prescribed. To avoid delays, arrange your telehealth visit early if you cannot get to an in-person office. Keep your pharmacy profile updated with any allergies and current medications to support safe dispensing. If you have difficulty swallowing, ask about chewable tablets or a liquid suspension. When in doubt, reach out—our licensed pharmacists are available to answer questions about dosing, timing, and potential side effects.
