How to take cefaclor
Before you start taking cefaclor, read the manufacturer's printed information leaflet from inside your pack.
The manufacturer's leaflet will give you more information about the antibiotic and a full list of side effects which you may experience from taking it.
Dosage
If you are taking capsules or liquid medicine, the usual dose for an adult is 250-500 mg three times daily. For a child, the usual dose is 62.5-250 mg three times daily, depending upon age.
Your doctor will tell you what dose is right for you (or your child) and this information will be printed on the label of the pack to remind you.
Your course of treatment may be for longer or shorter periods of time than mentioned here, so it is important that you take cefaclor exactly as your doctor tells you to.
If you have been given liquid medicine, read the directions carefully to make sure you measure out the correct amount of medicine. Cefaclor capsules and liquid medicine can be taken either before or after food, although they may start to work sooner if they are taken before food.
If you are taking cefaclor modified-release tablets (for example, Distaclor MR®), you will be prescribed one or two tablets to take twice daily. Take the tablets with meals and swallow the tablets whole - do not chew or break them.
Distribuya sus dosis de manera uniforme a lo largo del día. Siga tomando el antibiótico hasta que termine el tratamiento, a menos que le indiquen que lo suspenda. Completar el tratamiento completo es importante (incluso si siente que su infección ha desaparecido) para evitar que la infección regrese.
Missed dose
Si olvida tomar una dosis, tómela tan pronto como lo recuerde. Intente tomar el número correcto de dosis cada día, pero no tome dos dosis al mismo tiempo para compensar.
Obteniendo el máximo de tu tratamiento
Thrush (redness and itching in the mouth or vagina) may occur after taking antibiotics. If you think you have thrush speak with your doctor or pharmacist for advice.
Avoid antacids 2 hours before or after taking cefaclor, as they can reduce absorption.
If you take the oral contraceptive pill and have vomiting or diarrhoea lasting more than 24 hours, use extra contraception like condoms and ask your doctor or pharmacist for advice.
Cefaclor 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.
How to store cefaclor
Mantenga todos los medicamentos fuera del alcance y la vista de los niños.
