What YOMAX used for

YOMAX contains a penicillin called amoxycillin as the active ingredient.

YOMAX belongs to a group of medicines called penicillins

YOMAX is used to treat a range of infections caused by bacteria. These may be infections of the chest (pneumonia), tonsils (tonsillitis), sinuses (sinusitis), urinary and genital tract, skin and fleshy tissues.

YOMAX works by killing the bacteria that cause these infections.

YOMAX can also be used to prevent infection.

Your doctor may have prescribed YOMAX for another reason.

There is no evidence that YOMAX is addictive.

Before you take YOMAX

When you must not take it

  • You are allergic to penicillin or similar types of antibiotics such as cephalosporins. If you have ever had an allergic reaction (such as a rash) when taking an antibiotic you should tell your doctor before you take YOMAX.
  • You have ever had an allergic reaction to amoxycillin or any of the ingredients listed toward the end of this leaflet. (See "Ingredients")
  • the expiry date printed on the pack has passed.
  • the packaging is torn or shows signs of tampering.

Before you start to take it

Tell your doctor if:

  • You are allergic to foods, dyes, preservatives or any other medicines.
  • You have ever had an allergic reaction (such as a rash) to any antibiotics in the past.
  • You have glandular fever (mononucleosis) or a blood disorder.
  • You are pregnant or think you may be pregnant or are breast feeding. YOMAX may be used during pregnancy (Australian Use in Pregnancy Category A). YOMAX can pass to your baby from breast milk.
  • You have liver or kidney problems. The dosage of YOMAX may need to be changed or you may need to be given an alternative medicine.
  • You are taking any other medicines, including medicines you buy without a prescription. In particular tell your doctor if you are taking any of the following:
    - medicines used to treat gout eg probenecid or allopurinol.
    - the contraceptive pill. As with other antibiotics, you may need to use extra birth control methods eg. condoms.
    - other antibiotics. These may interfere with the actions of YOMAX.
    - Anticoagulants (used to prevent blood clots) such as warfarin.

How to take YOMAX

Follow your doctor's instructions about how and when to take YOMAX. Your doctor will advise how many doses are needed each day, and for how long you will need to take YOMAX.

Please read the direction label carefully. If you have any concerns about how to take YOMAX, talk to your doctor or pharmacist.

How much YOMAX to take

Take YOMAX as directed by your doctor or pharmacist.

The usual dose of YOMAX is one dose taken three times a day.

How to take YOMAX

Swallow YOMAX 250mg and 500mg capsules whole with a glass of water.

Space the doses as evenly as possible throughout the day. For example, if you are taking YOMAX three times a day, take a dose about every eight hours.

YOMAX can be taken with or without food. The effects of YOMAX are not changed by food.

How long to take YOMAX

Keep taking YOMAX until the course is finished or for as long as your doctor tells you.

Do not stop taking YOMAX just because you feel better as the infection can return.

Do not stop taking YOMAX, or change the dose without first checking with your doctor.

If you forget to take it

If you forget to take a dose of YOMAX, take it as soon as you remember. Then go back to taking it as directed by your doctor.

Do not take a double dose to make up for the dose that you have missed. Do not take two doses within an hour or so of each other. Taking more than the prescribed dose can increase the chance of unwanted side effects.

If you take too much (overdose)

If you (or someone else) has taken a large amount of YOMAX all at once, give plenty of water to drink and immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, if you think you or anyone else may have taken too much YOMAX, even if there are no signs of discomfort or poisoning. If you are not sure what to do, contact your doctor, pharmacist or nearest hospital.
