2. What you need to know before you take Amoxicillin

face or throat.

Warnings and Precautions
Talk to your healthcare professional before taking Amoxicillin if you:
- have infectious mononucleosis (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 healthcare professional before taking Amoxicillin.
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 healthcare professional that you are taking Amoxicillin. This is because Amoxicillin can affect the results of these tests.
Other medicines and Amoxicillin
Tell your healthcare professional, if you are taking, have recently taken or might take any other medicines.
If you are taking allopurinol (used for gout) with Amoxicillin, it may be more likely that you will have an allergic
skin reaction.
If you are taking probenecid, (used to treat gout), concomitant use of probenecid may reduce the excretion of
amoxicillin and is not recommended. Your healthcare professional may decide to adjust your dose of Amoxicillin.
- 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 may be less effective.
If you are taking methotrexate (used to treat cancer and severe psoriasis), penicillins may reduce the
excretion of methotrexate causing a potential increase in side effects.

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