1. What Clamoxyl is and what it is used for
What Clamoxyl is
Clamoxyl is an antibiotic. The active substance is amoxicillin. This belongs to a group of medicines called “penicillins”.
Antibiotics are used to treat bacterial infections and do not work for viral infections such as flu or the common cold. It is important that you follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor. Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw away medicines via wastewater or household waste. |
What Clamoxyl is used for
Clamoxyl is used to treat infections caused by bacteria in different parts of the body. Clamoxyl can also be used in combination with other medicines to treat stomach ulcers.
2. What you need to know before you take Clamoxyl
Do not take Clamoxyl
- 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 Clamoxyl if any of the above applies to you. If you are not sure, consult your doctor or pharmacist before taking Clamoxyl.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Clamoxyl if:
- you have infectious mononucleosis (fever, sore throat, swollen glands, and extreme tiredness)
- you have kidney problems
- you do not urinate regularly.
If you are not sure if any of the above symptoms apply to you, consult your doctor or pharmacist before taking Clamoxyl.
Blood and urine tests
If you are having:
- urine tests (glucose in urine) or blood tests for liver function
- estriol tests (used during pregnancy to check if the baby is developing normally).
Tell your doctor or pharmacist that you are taking Clamoxyl. This is because Clamoxyl can affect the results of these types of tests.
Other medicines and Clamoxyl
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
- If you are taking allopurinol (used for gout) with Clamoxyl, you may be more likely to suffer a skin allergic reaction.
- If you are taking probenecid (used to treat gout), it may reduce the excretion of amoxicillin and is not recommended. Your doctor may adjust the dose of Clamoxyl.
- If you are taking anticoagulants (such as warfarin), you may need more blood tests.
- If you are taking other antibiotics (such as tetracycline), Clamoxyl may be less effective.
- If you are taking methotrexate (a medicine used to treat cancer and severe psoriasis), penicillins can reduce the excretion of methotrexate and cause a potential increase in side effects.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Clamoxyl may have side effects such as allergic reactions, dizziness, and convulsions, which can make you unfit to drive.
Do not drive or operate machinery unless you are feeling well.

This medicine contains 20 mg of aspartame in each dispersible tablet. Aspartame is a source of phenylalanine, which may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body cannot eliminate it properly.
