Amoxicillin (Mox 500 / Novamox) in India — Uses, Adult & Pediatric Dosage, Price, and What Chemists Quietly Swap

Amoxicillin is India’s most-prescribed oral antibiotic — and one of the most quietly misused. A ₹4 strip from a Janaushadhi Kendra and a ₹95 strip from a city pharmacy contain the same molecule. Half the patients walking out with a Moxikind-CV strip never realise it is not the plain amoxicillin their doctor wrote. Pediatric doses are routinely guessed instead of calculated. The day-5 rash from glandular fever is mislabelled as penicillin allergy for life. This guide unpacks the Indian reality behind the prescription pad — what amoxicillin actually treats, how to dose it for adults and children, where it is being substituted, and the seven dosage habits Indian doctors still get wrong in 2026.

What Is Amoxicillin and How Does It Work?

Amoxicillin is a semi-synthetic aminopenicillin antibiotic. It belongs to the beta-lactam family and works by inhibiting the bacterial enzymes that build the peptidoglycan cell wall. Without a functional wall, the bacterium ruptures under its own internal pressure. The molecule is bactericidal, not just bacteriostatic, which means it kills bacteria outright rather than only halting their growth.

It is closely related to ampicillin but has better oral bioavailability — roughly 95 percent of an oral dose is absorbed compared to under 50 percent for ampicillin. That is why amoxicillin replaced ampicillin as the first-choice oral penicillin in almost every modern treatment guideline. Like all other penicillins, it is vulnerable to bacterial beta-lactamase enzymes. The fix is to add clavulanic acid, a beta-lactamase inhibitor, which produces the co-amoxiclav combination sold as Augmentin, Moxikind-CV and Clavam.

How Much Does Amoxicillin Cost in India in 2026?

The same molecule sells across a 23-fold price range depending on packaging and channel.

Form	Brand	Manufacturer	MRP per Strip	Notes
500mg capsule	Mox 500	Cipla	₹60 – ₹70	Most commonly prescribed
500mg capsule	Novamox 500	Cipla	₹80 – ₹95	Same as Mox, premium-priced
500mg capsule	Hi-Pen	Themis Medicare	₹35 – ₹45	Older brand, lower margin
500mg capsule	Almox 500	Aurobindo	₹40 – ₹55	Mass-market generic-branded
500mg capsule	Janaushadhi PMBJP generic	Various	₹4 – ₹8	90% cheaper, same molecule
250mg DT	Mox-DT 250 / Novamox-DT 250	Cipla	₹35 – ₹55	Pediatric dispersible
125mg DT	Mox-DT 125 / Novamox-DT 125	Cipla	₹25 – ₹40	Pediatric dispersible
125mg/5ml syrup	Novamox / Mox syrup	Cipla	₹35 – ₹55 (30ml)	Suspension for kids under 6
250mg/5ml syrup	Novamox-250 syrup	Cipla	₹55 – ₹80 (30ml)	Higher-strength pediatric
500+125mg co-amoxiclav	Augmentin 625	GSK	₹180 – ₹220	Innovator combination
500+125mg co-amoxiclav	Moxikind-CV 625	Cipla	₹130 – ₹160	Cipla’s combination
500+125mg co-amoxiclav	Clavam 625	Alkem	₹140 – ₹170	Alkem’s combination

A full 5-day course of plain amoxicillin 500 TID can cost as little as ₹15 at a Janaushadhi outlet and as much as ₹300 at a metro chain pharmacy stocking Novamox. The active ingredient is identical. As with paracetamol Dolo 650, the markup pays for marketing, MR visits and brand recall — not better medicine.

How Does India’s Amoxicillin Price Compare Globally?

Country	5-day Amoxicillin Course (500mg TID)	Context
India (Janaushadhi)	₹15 – ₹25	Government generic outlets
India (Mox/Novamox)	₹90 – ₹300	Private retail
United States	$8 – $25 (₹670 – ₹2,100)	Prescription-only; insurance dependent
United Kingdom	£3 – £9 (₹320 – ₹950)	NHS prescription free for eligible patients
UAE	AED 18 – 40 (₹400 – ₹900)	Pharmacist consult required

India is the cheapest source of amoxicillin in the world and one of the only countries where it routinely walks out of a pharmacy without a prescription. The same access that helps a labourer’s child get treated also drives the resistance crisis. This pricing pattern matters for international patients planning a medical trip to India — post-surgical antibiotics often cost less than the cab ride from the hospital.

What Does Amoxicillin Actually Treat?

Amoxicillin is first-line for a narrower set of indications than most Indian patients assume. It is not a general-purpose fever pill.

Clinically Proven First-Line Uses

• Streptococcal pharyngitis — group A strep sore throat, especially in children, to prevent rheumatic heart disease. Standard course is 10 days.
• Acute otitis media in children — high-dose 80 to 90mg per kg per day is now the Indian Academy of Pediatrics standard to overcome pneumococcal resistance.
• Acute bacterial sinusitis — when symptoms persist beyond 10 days, worsen after initial improvement, or are severe at onset.
• Community-acquired pneumonia — amoxicillin remains first-line for typical bacterial pneumonia in healthy adults under 65 without comorbidities.
• Dental infections — periapical abscess, pericoronitis and acute apical infection. Routinely prescribed before and after dental implant procedures, although blanket prophylaxis before every cleaning is not supported by current guidelines.
• Helicobacter pylori eradication — 1g twice daily for 14 days as part of triple or quadruple therapy.
• Skin and soft tissue infections — early cellulitis, erysipelas and impetigo when streptococcal cause is likely.
• Lyme disease — primary infection in pregnant women and children under 8.
• Post-surgical prophylaxis — selectively used after procedures such as hair transplant, knee replacement, and spine surgery where the surgeon’s protocol calls for an oral penicillin.

What Amoxicillin Does NOT Treat

• Viral infections — colds, most sore throats, viral bronchitis, flu, COVID-19, viral gastroenteritis. Taking amoxicillin for a viral fever does nothing except select for resistant bacteria in your own gut.
• Methicillin-resistant Staphylococcus aureus infections.
• Atypical pneumonia caused by Mycoplasma, Chlamydophila or Legionella. These need a macrolide such as azithromycin or a tetracycline.
• Most community urinary tract infections in India. Beta-lactamase-producing E. coli is now the dominant uropathogen — nitrofurantoin or fosfomycin is the rational first choice.
• Fungal infections, parasitic infections, all viral hepatitis and dengue.

What Is the Correct Adult Dose of Amoxicillin?

Adult dosing is driven by indication, not body weight. Renal function changes this — see the next section.

Indication	Dose	Frequency	Course Duration
Dental infection / abscess	500mg	3 times daily (every 8 hours)	5 days
Strep throat	500mg or 1g	2-3 times daily	10 days
Acute bacterial sinusitis	500mg	3 times daily	5-7 days
Community-acquired pneumonia	500mg – 1g	3 times daily	5-7 days
Uncomplicated UTI (if sensitive)	500mg	3 times daily	5-7 days
H. pylori eradication	1g	Twice daily, with PPI + clarithromycin or metronidazole	14 days
Endocarditis prophylaxis (cardiac high-risk)	2g	Single dose, 60 minutes before dental procedure	1 dose
Lyme disease	500mg	3 times daily	14-21 days

If symptoms have not improved by 72 hours, the diagnosis or the antibiotic choice needs to be reconsidered — that is the universal stop-and-rethink rule across Indian and international guidelines.

Renal Dose Adjustment Almost Nobody Does

Amoxicillin is renally cleared. In stage 3 to 5 chronic kidney disease, accumulation can cause crystalluria, neurotoxicity and rare seizures. Most Indian OPDs skip this step entirely.

Creatinine Clearance	Recommended Adjustment
> 30 ml/min	No adjustment
10 – 30 ml/min	250 – 500mg every 12 hours
< 10 ml/min	250 – 500mg every 24 hours
Haemodialysis	250 – 500mg every 24 hours, dose after dialysis

Elderly patients with longstanding diabetes, hypertension or recurrent UTIs frequently have an eGFR below 60 even when serum creatinine looks normal — and they are the same group routinely given 500mg TID without a thought.

What Is the Correct Pediatric Dose of Amoxicillin in India?

This is the area where Indian dosing goes wrong most often. Pediatric amoxicillin is weight-based, not age-based, and the dose differs by indication.

Indication	Daily Dose	Frequency	Course
General mild-to-moderate infection	25 – 45 mg/kg/day	Divided 2-3 times daily	5-7 days
Acute otitis media (IAP standard)	80 – 90 mg/kg/day	Divided 2 times daily	5-10 days
Streptococcal pharyngitis	50 mg/kg once daily	Once daily	10 days
Dental infection	50 mg/kg/day	Divided 3 times daily	5 days
Maximum daily dose	3 grams per day or as per indication

Worked Example — A 15kg, 3-year-old with Acute Otitis Media

• Target dose: 80mg per kg per day = 1,200mg per day
• Split into 2 doses = 600mg per dose
• Using Novamox-DT 250 dispersible tablets: 2.4 tablets per dose, twice daily. Rounded to 2 tablets twice daily for practical dosing, then verified by paediatrician.
• Using 250mg per 5ml syrup: 12ml twice daily.
• Course: 5 to 10 days based on severity.

The verbal half a tab thrice daily that many chemists give parents would deliver 375mg per day in this child — less than a third of the required dose for otitis. The same instruction in a 6kg infant would dangerously over-dose. The mg per kg per day calculation is non-negotiable.

What Indian Formulations of Amoxicillin Should I Know?

Form	Strength	Best For
Capsule	250mg, 500mg	Adults and older children able to swallow capsules
Dispersible Tablet (DT)	125mg, 250mg	Children — dissolve in clean water for accurate paediatric dosing
Oral Suspension	125mg / 5ml, 250mg / 5ml	Infants and toddlers; reconstitute with water at pharmacy
Co-amoxiclav tablet	500mg + 125mg (625)	Beta-lactamase-producing infections, mixed-flora abscesses
Co-amoxiclav suspension	200+28.5 / 400+57 per 5ml	Resistant childhood infections
Injectable amoxicillin / co-amoxiclav	500mg, 1g, 1.2g vials	Inpatient use, post-surgical

The WHO Essential Medicines List for children specifically recommends amoxicillin 250mg DT as the preferred paediatric formulation because it does not require refrigeration and allows precise weight-based dosing. Indian government supply chains have moved heavily towards DT for this reason. Cipla’s Novamox-DT and Mox-DT are the most stocked private brands.

Mox vs Novamox vs Moxikind-CV — The Silent Swap

This is the single most expensive and clinically significant mix-up at Indian pharmacy counters.

• Mox 500 — plain amoxicillin 500mg (Cipla, ₹60 – ₹70)
• Novamox 500 — plain amoxicillin 500mg (Cipla premium-priced version, ₹80 – ₹95)
• Moxikind-CV 625 — amoxicillin 500mg PLUS clavulanic acid 125mg (Cipla combination, ₹130 – ₹160)

A patient walks in with a prescription for Mox 500. The chemist is out of stock. He hands over Moxikind-CV 625 because the names sound similar and the margin is higher. The patient pays double, ends up with avoidable diarrhoea or vomiting on day 2, and the doctor never knows. The opposite swap also happens — a child needing clavulanic acid coverage for an abscess gets plain amoxicillin and the infection fails to clear.

Three checks every patient should make at the counter:

1. Read the strip foil, not the brand on the box. Plain amoxicillin will say AMOXICILLIN 500MG. Co-amoxiclav will say AMOXICILLIN 500MG + CLAVULANIC ACID 125MG.
2. Check the strength number. 500 is plain. 625 is the combination. 1g formulations exist for both but are less common in retail.
3. Ask if any substitution has been made from the original prescription. Indian law requires the chemist to disclose substitutions.

The hidden cost dimension is comparable to what plays out across surgical billing — for the non-obvious ways Indian hospital bills inflate, the pattern of small unannounced substitutions is the same playbook applied at smaller scale.

What Are the Side Effects of Amoxicillin?

Plain amoxicillin is one of the better-tolerated antibiotics. Most adverse events are gut-related.

Common (more than 1 in 10)

• Diarrhoea
• Nausea, mild abdominal discomfort
• Mild non-allergic skin rash, especially in viral co-infections

Less Common (1 in 100 to 1 in 1000)

• Oral or vaginal candidiasis (thrush) after the course
• Headache
• Transient liver enzyme elevation (more common with the clavulanic acid combination)
• Reversible alteration of taste

Rare but Serious

• True IgE-mediated penicillin allergy — hives, angioedema, bronchospasm, anaphylaxis. Onset usually within minutes to a couple of hours of a dose.
• Stevens-Johnson syndrome and toxic epidermal necrolysis — extremely rare.
• Clostridioides difficile colitis — much more common with the clavulanic acid combination than with plain amoxicillin.
• Crystalluria and acute interstitial nephritis at high doses or in dehydration.
• Cholestatic hepatitis — almost exclusively a co-amoxiclav effect; rare with plain amoxicillin.

The Epstein-Barr Virus Rash Trap

Between 80 and 90 percent of patients with undiagnosed infectious mononucleosis develop a maculopapular rash when given amoxicillin. The rash is NOT a true penicillin allergy. It is a benign, self-limited immune phenomenon. Indian doctors routinely label these patients as penicillin allergic for life, which closes the door on the safest, cheapest and most effective oral antibiotic class. If you or your child were called penicillin allergic after an amoxicillin rash during a teenage sore-throat episode, formal allergy testing is almost always worth it.

What Drug Interactions Matter With Amoxicillin?

Amoxicillin has fewer clinically meaningful interactions than most antibiotics. Two genuine ones, three Indian myths.

Real, Clinically Significant Interactions

• Methotrexate — amoxicillin reduces renal clearance of methotrexate; methotrexate toxicity can climb. Common scenario in rheumatoid arthritis, psoriasis and certain oncology regimens.
• Allopurinol — co-administration increases the risk of amoxicillin rash up to threefold, even without true allergy.
• Warfarin — INR can rise unpredictably during any antibiotic course because gut flora that produce vitamin K are killed. Patients on warfarin need INR rechecked mid-course.
• Probenecid — increases amoxicillin levels by blocking renal tubular secretion. Sometimes used deliberately for prolonged blood levels.

Common Indian Myths

• Amoxicillin and OCPs — modern evidence does not support a clinically significant interaction with combined oral contraceptive pills. Rifampicin is the real culprit, not amoxicillin.
• Amoxicillin and alcohol — no direct pharmacological interaction. The metronidazole rule does not apply.
• Amoxicillin and milk — no interaction. This is a tetracycline and ciprofloxacin issue, not an amoxicillin issue.

Compare this with the interaction profile of Ayurvedic herbs such as giloy, where the public mental model is reversed — patients assume herbs are interaction-free and antibiotics are dangerous, when the actual evidence often runs the other way.

Amoxicillin in Pregnancy and Breastfeeding

Amoxicillin is FDA pregnancy category B. Decades of human data show no increased risk of birth defects, miscarriage or developmental harm. It is one of the safer antibiotic choices for asymptomatic bacteriuria in pregnancy, dental infections, group B streptococcus prophylaxis and selected upper respiratory infections.

In breastfeeding, amoxicillin passes into breast milk at very low concentrations — generally less than 1 percent of the maternal weight-adjusted dose. It is considered compatible with breastfeeding. Possible infant effects include loose stools, oral thrush and rare rash.

The clavulanic acid combination has slightly more cholestatic hepatitis signal in late pregnancy and in some newborn studies. Plain amoxicillin is preferred when an alternative exists.

How Should I Store Amoxicillin in Indian Conditions?

• Capsules and tablets: Store below 25 degrees Celsius, away from direct light. Avoid car glove boxes, bathroom shelves above the shower and unventilated kitchen drawers in summer.
• Reconstituted oral suspension: Stable for 7 days at room temperature below 25 degrees Celsius, or 14 days refrigerated. In Indian summer, always refrigerate. Never freeze. Shake well before each dose. Discard at the 14-day mark even if syrup remains.
• Co-amoxiclav suspensions: Refrigerate after reconstitution. Discard after 7 days, regardless of remaining volume.

Tropical storage failure is a real reason for treatment non-response. A strip that has sat at 50 degrees Celsius in a parked car for two summer afternoons may have lost over 10 percent of its assay strength.

Antimicrobial Resistance — Where Amoxicillin Stands in India

The Indian Council of Medical Research AMR Surveillance Network publishes annual data showing how resistance is shifting.

• Streptococcus pneumoniae: 20 to 35 percent of metro isolates show reduced penicillin susceptibility. The fix has been higher amoxicillin doses in otitis and pneumonia rather than abandoning the molecule.
• Group A streptococcus: Resistance to penicillin remains essentially zero. Amoxicillin is still the gold standard for strep throat.
• Escherichia coli in community UTIs: 60 to 80 percent of Indian community isolates produce beta-lactamase. Plain amoxicillin is no longer reliable for UTI.
• Helicobacter pylori: Resistance to amoxicillin itself stays under 5 percent, but clarithromycin resistance is 30 to 50 percent in Indian metros, which is why first-line triple therapy is increasingly failing on its non-amoxicillin component.
• Salmonella typhi and paratyphi: Most isolates are no longer susceptible to amoxicillin in India; cephalosporins or azithromycin are first-line for typhoid.

The single most effective thing any Indian patient can do for personal and population antimicrobial stewardship is not to take amoxicillin for viral fevers, not to share leftover strips inside the family and not to insist on antibiotic prescriptions during routine OPD visits for self-limited illness.

Janaushadhi vs Branded — The 90 Percent Cost Saving Indians Miss

Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) outlets sell amoxicillin 500mg at ₹4 to ₹8 per strip of 10. The same molecule rebranded as Mox or Novamox costs ₹60 to ₹95. The manufacturing base for many Janaushadhi suppliers overlaps with the same WHO-GMP-certified facilities that produce branded versions for Cipla, Aurobindo and Sun Pharma.

A 5-day adult amoxicillin course can cost ₹15 at a Janaushadhi outlet versus ₹150 to ₹300 at a private chain pharmacy. For a family on a monthly antibiotic spend that includes paracetamol, an antacid and an antihistamine, the annual saving is substantial. The barriers are awareness — most Indians do not know Janaushadhi stocks amoxicillin — and accessibility, since outlets are concentrated in district hospital campuses and not every neighbourhood.

For comparable pricing context, see how Indian patients navigate FDA-approved drug pricing across 2026 launches — the gap between innovator price and Indian generic price often dwarfs the gap between two Indian brands of the same generic.

When Should I NOT Use Amoxicillin?

• Viral illness without bacterial superinfection — colds, viral sore throat, flu, COVID, dengue, viral hepatitis, viral GE.
• Confirmed IgE-mediated penicillin allergy with anaphylaxis or angioedema in the prior history.
• Severe renal failure without dose adjustment.
• Routine dental cleaning in patients without high-risk cardiac conditions per current AHA guidance.
• Asymptomatic bacteriuria in non-pregnant adults — does not need treatment in most cases.
• Empirical UTI treatment in adults when local E. coli beta-lactamase rates exceed 20 percent — which is most of India.
• As a routine post-extraction painkiller — amoxicillin is not an analgesic. Pain is better addressed with paracetamol at appropriate doses.

International patients flying in for dental procedures should be aware that Indian dental antibiotic protocols are often more liberal than Western ones. If you are coming in for NRI dental treatment, ask whether the antibiotic is genuinely indicated or routine.
