Getting the most from your treatment

To prevent an unwanted pregnancy you should use a barrier method of contraception such as a condom while you are taking cefalexin and for at least 7 days after the course of treatment has ended. If the week following the antibiotic course runs into your pill free week, the next pack of oral contraceptives should be started immediately, without a break. If you are taking the form of contraceptive pill which is taken every day or need further advice, speak to your doctor or pharmacist.
• If you buy any medicines, check with a pharmacist that they are safe to take with cefalexin.
