What Amoxicillin Capsules are

Amoxicillin Capsules are antibiotics. The active ingredient is amoxicillin. This belongs to a group of medicines called ‘penicillin’.

What Amoxicillin Capsules are used for

Amoxicillin Capsules are used to treat infections caused by bacteria in different parts of the body. Amoxicillin Capsules may also be used in combination with other medicines to treat stomach ulcers.


Do not take Amoxicillin Capsules:

  • if you are allergic to amoxicillin, penicillin or any of the other ingredients of this medicine (listed in section 6).
  • if you have ever had an allergic reaction to any antibiotic. This can include a skin rash or swelling of the face or throat.

Do not take Amoxicillin Capsules if any of the above apply. If you are not sure, talk to your doctor or pharmacist before taking Amoxicillin Capsules.

Warnings and precautions

Talk to your doctor or pharmacist before taking Amoxicillin Capsules if you:

  • have glandular fever (fever, sore throat, swollen glands and extreme tiredness)
  • have kidney problems
  • are not urinating regularly.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Amoxicillin Capsules.

Blood and urine tests

If you are having:

  • Urine tests (glucose) or blood tests for liver function
  • Oestriol tests (used during pregnancy to check the baby is developing normally)

Tell your doctor or pharmacist that you are taking Amoxicillin. This is because Amoxicillin Capsules can affect the results of these tests.

Other medicines and Amoxicillin Capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

  • If you are taking allopurinol (used for gout) with Amoxicillin Capsules, it may be more likely that you will have an allergic skin reaction.
  • If you are taking probenecid (used for gout), your doctor may decide to adjust your dose of Amoxicillin Capsules.
  • If you are taking medicines to help stop blood clots (such as warfarin), you may need extra blood tests.
  • If you are taking other antibiotics (such as tetracycline) Amoxicillin Capsules may be less effective.
  • If you are taking methotrexate (used for the treatment of cancer and severe psoriasis) Amoxicillin Capsules may cause an increase in side effects.
  • If you are taking oral typhoid vaccine (may not work if taken with amoxicillin)

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Amoxicillin Capsules can have side effects and the symptoms (such as allergic reactions, dizziness and convulsions) may make you unfit to drive.

How long should you take Amoxicillin for?

  • Keep taking Amoxicillin Capsules for as long as your doctor has told you to, even if you feel better. You need every dose to help fight the infection. If some bacteria survive they can cause the infection to come back.
  • Once you finish treatment, if you still feel unwell you should go back to the doctor.

Thrush (a yeast infection of moist areas of the body which can cause soreness, itching and white discharge) may develop if Amoxicillin is used for a long time. If this occurs tell your doctor.

General advice regarding the use of antibiotics

Antibiotics are used to treat infections caused by bacteria. They have no effect against infections caused by viruses.

Sometimes an infection caused by bacteria does not respond to a course of an antibiotic. One of the commonest reasons for this to occur is because the bacteria causing the infection are resistant to the antibiotic that is being taken. This means that they can survive and even multiply despite the antibiotic.

Bacteria can become resistant to antibiotics for many reasons. Using antibiotics carefully can help to reduce the chance of bacteria becoming resistant to them.

When your doctor prescribes a course of an antibiotic it is intended to treat only your current illness. Paying attention to the following advice will help prevent the emergence of resistant bacteria that could stop the antibiotic working.

1. It is very important that you take the antibiotic at the right dose, at the right times and for the right number of days. Read the instructions on the label and if you do not understand anything ask your doctor or pharmacist to explain.
2. You should not take an antibiotic unless it has been prescribed specifically for you and you should use it only to treat the infection for which it was prescribed.
3. You should not take antibiotics that have been prescribed for other people even if they had an infection that was similar to yours.
4. You should not give antibiotics that were prescribed for you to other people.
5. If you have any antibiotic left over when you have taken the course as directed by your doctor you should take the remainder to a pharmacy for appropriate disposal.
