Amoxicillin 1000mg is the top strength in the amoxicillin range: a full gram of the penicillin antibiotic in a single tablet. It exists for the regimens at the high end of what doctors prescribe — severe or stubborn respiratory infections, dental infections needing aggressive coverage, and Helicobacter pylori eradication protocols, which commonly use 1000mg per dose. The typical buyer is an adult whose doctor has explicitly written a high-dose course and who prefers one tablet to swallowing two 500mg capsules per dose. This is emphatically not the strength for a first-ever antibiotic course or an unconfirmed infection. Our amoxicillin uses and safety guide explains where amoxicillin genuinely belongs.
A gram of amoxicillin pushes blood levels well above the concentration susceptible bacteria can survive, and does so within an hour or two of each dose. As with every strength, though, the honest measure is days: expect meaningful symptom improvement within one to three days for most infections the leaflet covers. High-dose courses described in the leaflet typically run from several days for routine infections to the fixed multi-day schedules used in H. pylori combination therapy. Because 1000mg regimens usually target harder infections, finishing the entire course matters even more than usual — the bacteria being treated are exactly the kind that exploit an early stop. Worsening symptoms or no change by day three warrants a doctor, not more tablets.
Only if a doctor said so. Bigger is not better with antibiotics: the correct strength is the one matching your prescribed regimen, and for most adults that is Amoxicillin 500mg. Amoxicillin 1000mg is not a starting dose, and dose-dependent side effects — nausea, diarrhoea, stomach pain, thrush — are at their most likely here. Amoxicillin 650mg offers a step down for those who need more than 500mg but tolerate the full gram poorly, and Amoxicillin 250mg covers deliberately low-dose regimens. If penicillins are ruled out by allergy, the sulfa combination Bactrim DS is a different class your doctor may consider. Self-escalating to 1000mg to "beat" an infection faster is how people earn side effects without extra benefit.
Treat this strength with respect. Take each Amoxicillin 1000mg tablet with a full glass of water — it is a large tablet — and with food if your stomach objects, spacing doses exactly as the leaflet describes. Complete the whole course; high-dose regimens exist because the infection demands sustained pressure, and gaps or early stops squander that. Avoid alcohol entirely until you finish: at this dose the gastrointestinal burden is already significant. Diarrhoea is the most common complaint — stay hydrated, and see a doctor urgently if it turns severe, watery or bloody. Stop immediately for any rash, swelling or breathing difficulty. Disclose methotrexate, allopurinol and warfarin use beforehand, and never share leftover tablets.
At maximum strength, provenance matters most. Kamagra AUS ships Amoxicillin 1000mg solely as sealed, GMP-certified manufacturer packs — batch number and expiry embossed on each blister, patient information leaflet enclosed — never loose or repackaged tablets. Our WhatsApp verification call before dispatch doubles as a safety check: we confirm you intend the 1000mg strength specifically and that it matches your doctor's direction. Delivery across Australia takes 2–4 business days in plain packaging with free shipping over $150. Pricing is $75.15 for 20 tablets, $110.27 for 30, $175.61 for 50 and $334.89 for 100. Order the quantity a single course requires; antibiotics are not for stockpiling.
Amoxicillin 1000mg is the highest strength we carry, and it is worth being direct: gastrointestinal side effects scale with dose, so nausea, diarrhoea and stomach discomfort are somewhat more likely at 1000mg than with smaller tablets. Other common effects include skin rash, headache and post-course thrush as the antibiotic disturbs normal bacterial flora. Taking the tablet with food and plenty of water helps most people tolerate it. Rare but serious reactions require emergency care regardless of dose: swelling of the face, lips or throat with breathing difficulty (anaphylaxis), a severe blistering or peeling rash such as Stevens-Johnson syndrome, persistent watery or bloody diarrhoea suggesting C. difficile infection, or jaundice with dark urine indicating liver injury. Stop the medicine and seek medical help immediately if any of these develop.
Penicillin allergy is the absolute barrier: Amoxicillin 1000mg must never be taken by anyone who has reacted to amoxicillin, ampicillin or any penicillin, and a severe cephalosporin allergy also warrants avoidance due to cross-reactivity. At this high strength, kidney function matters even more — people with moderate or severe kidney impairment need a doctor to reduce the dose or lengthen the interval, and 1000mg may simply be inappropriate for them. Avoid it during glandular fever (infectious mononucleosis), which commonly provokes an extensive rash, and after any previous amoxicillin-related liver problem. Interactions to raise with a prescriber: allopurinol (higher rash risk), warfarin (enhanced anticoagulation), methotrexate (increased toxicity), and combined oral contraceptives, whose protection can lapse if the course triggers vomiting or diarrhoea.
Keep Amoxicillin 1000mg in its original blister strips, below 25°C, in a dry place shielded from sunlight — never decant tablets into pill boxes days in advance, as exposure to moisture degrades amoxicillin. Store the pack out of children's sight and reach. Because 1000mg is a large tablet, inspect each blister pocket easily: the foil should be fully sealed with no lifting at the edges, the batch number and expiry date must be printed on both the strip and the outer carton and must match, the box should arrive intact, and the patient information leaflet should be inside. Any sign of tampering or mismatched details — set the pack aside and contact our team before use.
Amoxicillin 1000mg is priced at $75.15 for 20 tablets on Kamagra AUS — $3.76 per tablet — falling to about $3.35 each when you take the 100-tablet pack at $334.89, a saving of roughly 11% per dose. The 30-pack costs $110.27 (about $3.68 per tablet) and the 50-pack $175.61 ($3.51). The 50 and 100 packs both clear our $150 free-delivery threshold — well, the 50-pack sits just under it at $175.61, so only the 100-pack ships free. Per milligram of active ingredient, 1000mg is the most economical strength we stock, but choose it only if your prescribed regimen actually calls for 1000mg doses.
General information about the active ingredient in Amoxicillin 1000mg.
See the full Amoxicillin guide & all Amoxicillin productsAmoxicillin is a broad-spectrum antibiotic belonging to the penicillin family (an aminopenicillin). It is prescribed by doctors to treat a range of bacterial infections, including certain chest and respiratory tract infections, ear, nose and throat infections, urinary tract infections, and some skin and dental infections. It works only against bacteria and has no effect on infections caused by viruses, such as colds and most cases of flu.
Amoxicillin interferes with the ability of bacteria to build and maintain their cell walls. By binding to specific proteins involved in cell-wall construction, it weakens the wall so that the bacterium cannot survive and multiply, leading to its death. Because human cells do not have this type of cell wall, the medicine targets bacteria selectively. It is bactericidal, meaning it kills susceptible bacteria rather than simply stopping their growth.
Always take amoxicillin exactly as prescribed and as described in the patient information leaflet. It is available as capsules, tablets and an oral liquid, and can usually be taken with or without food. Space the doses evenly through the day as directed. It is very important to complete the entire course, even if you feel better before it is finished, because stopping early can allow the infection to return and contributes to antibiotic resistance.
Common (usually mild and temporary):
Stop and seek medical help if you experience:
Store in the original packaging below 25°C, away from heat, light and moisture, out of the sight and reach of children. Oral liquid is usually kept only a short time after mixing and may need refrigeration — follow the label. Do not use after the expiry date.
Alcohol does not usually stop amoxicillin from working, but it is sensible to limit alcohol while you are unwell so your body can recover. If you have concerns, ask your doctor or pharmacist.
Completing the full course helps ensure the infection is fully cleared and reduces the chance of bacteria surviving and becoming resistant. Stopping early because you feel better can allow the infection to return.
No. Colds and most cases of flu are caused by viruses, and antibiotics only work against bacteria. Taking it for a viral illness will not help and contributes to antibiotic resistance.

The active ingredient in Amoxicillin 1000mg is Amoxicillin — the same molecule used in the branded equivalent, manufactured under GMP conditions. Always read the patient information leaflet and consult a doctor or pharmacist before first use.
Choose your method at checkout: secure bank transfer, PayID, credit/debit card, or PayPal. You'll receive clear payment instructions by email, and we dispatch within one business day of payment clearing.
Yes. Every order ships in plain, unbranded outer packaging — nothing on the outside indicates the contents or the pharmacy.
For most routine adult infections, yes — the standard prescribed strength is 500mg, and doctors reserve 1000mg per dose for severe infections, resistant organisms, or protocols like H. pylori eradication. Higher dose means higher side-effect risk without automatic extra benefit. Use 1000mg only when a doctor has directed that exact strength.
The amoxicillin content is identical, and a single tablet is more convenient for genuine high-dose regimens. But that equivalence is not permission to double a 500mg prescription — the regimen a doctor set is calibrated to your infection. Match the strength you were prescribed; do not construct higher doses yourself.
The common ones are dose-related and therefore most likely at this strength: nausea, diarrhoea, stomach discomfort, and oral or vaginal thrush from disrupted normal flora. Allergic reactions — rash, hives, swelling, wheezing — can occur at any dose and require stopping immediately. Read the enclosed leaflet fully before the first tablet.
Yes — 1000mg amoxicillin per dose is a standard component of H. pylori eradication regimens, always combined with an acid-reducing medicine and at least one other antibiotic for a fixed number of days. These protocols must be assembled and supervised by a doctor; amoxicillin alone will not eradicate H. pylori.
Not without medical advice. Amoxicillin is cleared by the kidneys, and reduced kidney function means the drug accumulates — doctors typically lower the dose or lengthen the interval, often using smaller strengths like 250mg or 500mg instead. Tell your doctor about any kidney condition before considering the 1000mg tablet.
Alcohol does not chemically clash with amoxicillin, but at the 1000mg strength stomach upset is already more likely, and alcohol makes nausea and dehydration worse. While a single drink is unlikely to cause harm, abstaining until the course ends is the sensible choice and helps your body fight the infection.
Yes, at this strength we recommend it. Although food does not reduce amoxicillin absorption, a 1000mg dose on an empty stomach commonly causes nausea. Take each tablet at the start of a meal with a full glass of water, and keep doses evenly spaced through the day.
Only if the tablet carries a score line and a prescriber approves — many 1000mg tablets are scored precisely for this. If yours is unscored, do not cut it, as halves can be uneven. Since we stock Amoxicillin 500mg separately, ordering the correct strength is the more reliable option.
Despite the higher dose, clearance is similar to other strengths: amoxicillin's half-life is around 60–90 minutes with healthy kidneys, so the drug is effectively gone within about 24 hours of the last tablet. People with reduced kidney function clear it more slowly and need medically adjusted dosing.
No improvement after 48–72 hours of proper dosing means the treatment needs reviewing, not repeating. The bacteria may be resistant, or the infection may not be bacterial at all. See a doctor for reassessment — they may culture a sample or switch antibiotic classes. Never restart a fresh course on your own initiative.
