Sign inBefore taking cefaclor
Before taking cefaclor make sure your doctor or pharmacist knows:
- If you are pregnant or breast-feeding.
- If you have kidney problems.
- If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
- If you have ever had an allergic reaction to this or any other medicine. It is particularly important that you tell your doctor if you are allergic to any other antibiotics.
How to take cefaclor
- Before beginning treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take cefaclor exactly as your doctor has told you.
- If you have been given modified-release tablets (Distaclor MR®) these should be swallowed whole with or soon after a meal. Do not chew these tablets.
- Take cefaclor at regular intervals and complete the prescribed course. It is important to take the full course (even if you feel your infection has cleared up) to prevent the infection from coming back.
- Try to take cefaclor at the same times each day to avoid missing any doses.
- If you forget to take 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. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Some people develop thrush (redness and itching in the mouth or vagina) after taking a course of antibiotics. If you think you have thrush speak with your doctor or pharmacist for advice.
- If you are using oral combined hormonal contraception (the 'pill'), additional contraceptive precautions such as condoms are not required during a course of this antibiotic unless you are sick or have diarrhoea. If you need further advice, speak with your doctor or pharmacist.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking cefaclor.
- This antibiotic may stop the oral typhoid vaccine from working. If you are having any vaccinations, make sure the person treating you knows that you are taking this medicine.
- If you buy any medicines, check with a pharmacist that they are safe to take with cefaclor.
