What is Amoxicillin?

What is Amoxicillin?

Amoxicillin is used in the treatment of various bacterial infections. It's categorised as a penicillin-type antibiotic. It works by killing the bacteria that cause the infection. It only treats bacterial infections and does not work for viral infections. Any use of an antibiotic when it isn't needed can make it not work for future infections. When combined with other medications, Amoxicillin can also be used to treat stomach/intestinal ulcers that result from the bacteria H. pylori. It can also prevent the ulcers from recurring. Amoxicillin does not treat the underlying cause of a dental infection, so you should still see a dentist as soon as possible.

How Does Amoxicillin Work?

Bacteria are microscopic single-cell microbes that surround us. Some of them are helpful, for instance, some bacteria in the gut help to break down food. However, when some bacteria enter the body either through the airway, mouth, eyes, or urogenital openings, they can cause infections. Amoxicillin works by stopping bacteria from building their cell walls, which kills them. This helps your body clear the infection and relieves the symptoms.

Common uses include dental abscesses, chest infections (including pneumonia), ear, nose and throat infections and urinary tract infections.

How to use Amoxicillin

Follow the instructions given by your clinician and the patient information leaflet. For adults and children over 40kg, the usual dose is 250-500mg three times daily. For a dental infection, the usual adult dose is 500mg three times a day. The dose may vary based on the infection's severity.

  • Space your doses evenly through the day, at least 4 hours apart.
  • You can take the capsules before, during or after food.
  • Swallow the capsules whole with a drink of water, without opening them.
  • Keep taking Amoxicillin for as long as your clinician has told you to, even if your symptoms improve sooner.
Possible side effects

Common side effects may include:

  • Nausea
  • Diarrhoea
  • Skin rash

Less common side effects include vomiting, thrush (a yeast infection) and dizziness. Rare but serious side effects can include allergic reactions (such as swelling of the face, lips or tongue, or difficulty breathing), severe skin reactions, severe or bloody diarrhoea, liver problems (such as yellowing of the skin or eyes) and kidney problems. Stop taking Amoxicillin and see a doctor straight away if any of these occur.

Warnings and precautions

Do not take Amoxicillin if you are allergic to penicillin or any of its ingredients, or if you have ever had an allergic reaction to any antibiotic.

  • Caution is advised for those with kidney problems, as the dose might need adjustment.
  • Pregnant or breastfeeding individuals should consult a doctor before use.
  • Tell your doctor if you take allopurinol or probenecid (for gout), warfarin or other blood thinners, methotrexate, or other antibiotics such as tetracyclines.
  • Inform your doctor of any underlying medical conditions, especially glandular fever or if you are not passing urine regularly.
  • Do not share your medication with others, even if they have similar symptoms.
  • Call 999 or go to A&E if you have a lot of swelling in your mouth or face, or difficulty breathing or swallowing. If you think you have a dental abscess, contact a dentist or NHS 111 urgently.
What are the ingredients in Amoxicillin?

Each capsule contains 500mg of amoxicillin (as amoxicillin trihydrate). The other ingredients can vary between manufacturers, so check the patient information leaflet supplied with your capsules. They may include colloidal anhydrous silica, magnesium stearate, gelatin, titanium dioxide, iron oxide yellow, carmoisine and quinoline yellow.

Frequently asked questions

Everything you need to know about Amoxicillin before you start.

1. Do I need a prescription for Amoxicillin?

Yes. Amoxicillin is a prescription-only antibiotic in the UK. With SwiftDoctor, you complete an online consultation and a UK-registered clinician reviews your answers. Antibiotics are only prescribed when they are suitable for your symptoms. If Amoxicillin is suitable, a prescription is issued and your capsules are sent in discreet, tracked delivery.

2. How long does Amoxicillin take to work?

For most infections you should start to feel better within a few days. Tell your doctor if you have not started to feel better after 3 to 5 days of taking it.

3. Can I drink alcohol while taking Amoxicillin?

Yes, you can drink alcohol while taking amoxicillin. If you feel unwell or sick, drinking may make you feel worse, so it is sensible to avoid it until you feel better.

4. Does Amoxicillin affect the contraceptive pill?

No. Amoxicillin does not stop any type of contraception from working, including the combined pill, the progestogen-only pill and emergency contraception. However, if it makes you vomit, or you have severe watery diarrhoea or diarrhoea that lasts for more than 24 hours, your contraceptive pill may not protect you from pregnancy.

5. What should I do if I miss a dose?

If you miss a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case skip the missed dose. Do not take a double dose to make up for a missed one, and leave at least 4 hours between doses.
