  • Swallow azithromycin capsules whole (not crushed or chewed), with plenty of water.
  • Take azithromycin at least one hour before food or at least two hours after food.
  • Try to take this medicine at regular intervals, as directed by your doctor, to keep a steady level of azithromycin in your body.
  • Try not to miss any doses. If you do miss a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Never take two doses at the same time to make up.

  • Azithromycin can cause drowsiness and dizziness. Make sure your reactions are normal before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert.

In addition to taking the contraceptive pill, use a barrier method of contraception (e.g. condoms) while you are taking azithromycin and for at least seven days after your course of azithromycin has finished. If these seven days run into a 'pill-free' week, start taking the next packet of contraceptives without leaving a break. If you are taking the type of contraceptive pill that is taken every day or if you need any further advice, speak to your doctor or pharmacist.

PS - Health and Poverty

Perhaps the biggest cause of ill health in the world is poverty. Help to Make Poverty History. For example, why not lend some of your money to disadvantaged communities to enable them to trade their way out of poverty through schemes such as Shared Interest.
