MYMOX contains the active ingredient amoxicillin, which belongs to a group of medicines called penicillins. MYMOX is used to treat infections caused by certain bacteria in different parts of the body.
1. What MYMOX is and what it is used for
2. What you need to know before you take MYMOX
Do not take MYMOX:
- If you are hypersensitive (allergic) to amoxicillin trihydrate, penicillins, cephalosporins or any of the other ingredients of MYMOX (listed in section 6).
- If you have ever had an allergic reaction to any antibiotic, which can include a skin rash or swelling of the face or throat.
Warnings and precautions
Take special care with MYMOX:
- If you have epilepsy or meningeal disorders (inflammation of the membranes and fluid surrounding the brain and spinal cord), as MYMOX may increase the risk of convulsions (fits) when taken at high doses.
- If you have kidney problems or are not urinating frequently.
- If you have liver problems.
- If you have been diagnosed with infectious mononucleosis, also called glandular fever (fever, sore throat, swollen glands and extreme tiredness).
- If you have been diagnosed with lymphatic leukaemia.
- If you develop diarrhoea and stomach cramps, which may happen while you are taking MYMOX or a few months after you have stopped taking MYMOX.
If you are having certain laboratory tests done, such as liver function tests, urine glucose testing or oestriol testing (done during pregnancy). MYMOX can affect the results of some of these tests.
Children
MYMOX capsules are not suitable for breaking to accommodate lower dosing requirements. Different formulations should be considered in children under the age of 12 years.
Other medicines and MYMOX
Always tell your health care provider if you are taking any other medicine (this includes all complementary or traditional medicines). Tell your doctor or pharmacist if you are currently taking:
- Medicines to thin your blood and prevent blood clots from forming (such as warfarin), as you may need additional blood tests.
- Probenecid (used to treat gout).
- Allopurinol (used to treat gout), as it may be more likely that you can have an allergic skin reaction when taking MYMOX.
- Other antibiotics (such as tetracycline), as MYMOX may be less effective.
- Methotrexate (used to treat cancer, rheumatoid arthritis and severe psoriasis), as MYMOX may cause an increase in side effects.
- Oral contraceptives, as MYMOX may affect the efficacy of some of these medicines.
Pregnancy, breastfeeding and fertility
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, please consult your doctor, pharmacist or other health care provider for advice before taking MYMOX. Breastfeeding while taking MYMOX is not advised.
Driving and using machines
MYMOX may cause side effects, such as allergic reactions, dizziness, drowsiness and convulsions (fits) and can affect your ability to drive a vehicle and use machines. Do not drive a vehicle and use machines until you know how MYMOX affects you.
MYMOX contains colourants MYMOX 250 contains tartrazine and MYMOX 500 contains tartrazine and sunset yellow FCF as colourants, which may cause allergic reactions.
3. How to take MYMOX
Do not share medicines prescribed for you with any other person. Always take MYMOX exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Adults: The usual dose of MYMOX is 250 mg to 500 mg three times a day. Your doctor may prescribe you a different dose depending on the severity and type of infection, or your kidney function. Space the doses evenly during the day, at least 4 hours apart.
MYMOX may be taken with or without food. Swallow with water without opening the capsule. Your doctor will tell you how long your treatment with MYMOX will last. If you have the impression that the effect of MYMOX is too strong or too weak, tell your doctor or pharmacist.
If you take more MYMOX than you should
In the event of overdosage, consult your doctor or pharmacist. If neither is available, contact the nearest hospital or poison centre. Take the remaining capsules with you so your doctor will know what you have taken. Symptoms of overdose: an upset stomach, such as nausea (feeling sick), vomiting (being sick) or diarrhoea, crystals in the urine, which may be seen as cloudy urine, or problems urinating.
If you forget to take MYMOX
If you have missed a dose of MYMOX, take the missed dose as soon as you remember. Do not take the next dose too soon, wait about 4 hours before taking the next dose. Do not take a double dose to make up for forgotten individual doses.
If you stop taking MYMOX
Keep taking MYMOX for as long as your doctor has told you to, even if you feel better. MYMOX is an antibiotic and it is important that you take every dose to help fight the infection. If you finish your treatment with MYMOX and still feel unwell, please consult your doctor.

- Painful, blistering or peeling skin rash, such as Stevens - Johnson syndrome or toxic epidermal necrolysis.
- Flu - like symptoms with a rash, fever, swollen glands, and abnormal blood test results (including increased white blood cells [eosinophilia] and liver enzymes), also called drug reaction with eosinophilia and systemic symptoms (DRESS).
- Severe skin reactions, which can include changes in skin colour, bumps under the skin, blistering, pustules, peeling, redness, pain, itching, scaling. These may be associated with fever, headaches and body aches.
- Itchy reddish - purple patches on the skin, especially on the palms of the hands or soles of the feet, ‘hive - like’ raised swollen areas on the skin, tender areas on the surfaces of the mouth, eyes and genitals. You may have a fever and be very tired (erythema multiforme).
- Rash or pinpoint flat red round spots under the skin surface or bruising of the skin. This is due to inflammation of blood vessel walls due to an allergic reaction. It can be associated with joint pain (arthritis) and kidney problems.

- Inflammation of the large bowel (colon) with diarrhoea (sometimes containing blood), pain and fever.

It is a certain kind of allergic reaction with the leading symptom of repetitive vomiting (1 – 4 hours after medicine intake). Further symptoms could include stomach pain, lack of energy, diarrhoea and low blood pressure.
- Chest pain due to an allergic reaction, which may be a symptom of an allergy triggered heart attack (Kounis syndrome).
