Before you take cefradine, make sure your doctor knows if you have ever had an allergic reaction to any other antibiotic.
Space your doses out evenly over the day and complete the full course of the antibiotic, even if you feel your infection has cleared up.
The most common side-effect is diarrhoea, which is usually mild and soon passes. If it becomes severe or lasts for more than 24 hours, you should speak with your doctor.

About cefradine
Tipo di medicinale | A cephalosporin antibiotic |
Utilizzato per | Infezioni |
Chiamato anche | Cephradine (in US) |
Disponibile come | Capsule |
Cefradine is a broad-spectrum antibiotico, which means that it is active against a wide variety of bacteria. It is used to treat bacterial infections such as urinary tract infections, skin infections, chest e throat infections, infezioni dell'orecchio e sinusite. It is suitable for adults and older children, and can be taken during pregnancy. Some people who are allergic to penicillin antibiotics may not be able to take cefradine, so make sure your doctor knows if you have ever had an allergic reaction to any other antibiotic.
Cefradine treats an infection by killing the bacteria that are causing it.
Before taking cefradine
Torna ai contenutiSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking cefradine it is important that your doctor knows:
If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you have had a bad reaction to a penicillin or cephalosporin antibiotic.
Se hai problemi con il funzionamento dei tuoi reni.
If you are pregnant, trying for a baby or breastfeeding. (Although cefradine is not known to be harmful to babies, it is still important that you tell your doctor if you are expecting or breastfeeding a baby.)
Se stai assumendo o utilizzando altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione, così come i medicinali a base di erbe e complementari.

How to take cefradine
Torna ai contenutiBefore you start taking cefradine, 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.
There are two strengths of cefradine capsules available: 250 mg and 500 mg. It is usual to be prescribed either 250-500 mg to be taken four times a day, or 500 mg-1 g to be taken twice a day. Your doctor will tell you which dose is right for you, and this information will be printed on the label of the pack to remind you. Take the capsules exactly as your doctor tells you to. Your doctor will also tell you how long your course of treatment will last - this is commonly about five days.
Cefradine capsules can be taken either before or after food, although they may start to work a little sooner if they are taken before food.
Space your doses out evenly throughout the day. Keep taking the antibiotic until the course is finished unless you are told to stop. Taking the full course is important (even if you feel your infection has cleared up) in order to prevent the infection from coming back.
If you forget to take a dose, take one as soon as you remember. Try to take the correct number of doses each day, but do not take two doses at the same time to make up.
Ottenere il massimo dal tuo trattamento
Torna ai contenutiSome 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 recommended for a time if you have sickness (vomiting) or diarrhoea which lasts for more than 24 hours. If you need further advice about this, speak with your doctor or pharmacist.
If you are having an operation or any other medical treatment, tell the person carrying out the treatment that you are taking an antibiotic. This is because cefradine may interfere with the results of some tests to check for sugar in your urine.
Cefradine 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 antibiotic.

Can cefradine cause problems?
Torna ai contenutiAlong with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with cefradine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
Effetti collaterali comuni cefradine side-effects | Cosa posso fare se sperimento questo? |
Diarrea | Drink plenty of water to replace any lost fluids. If the diarrhoea continues for longer than 24 hours, becomes severe, or contains blood, let your doctor know immediatamente |
Vertigini | If affected, do not drive and do not operate any tools or machinery until you feel better |
Feeling sick (nausea) or being sick (vomiting), tummy (abdominal) discomfort | Stick to simple foods. If you are not already doing so, try taking your doses after meals |
Eruzione cutanea e altre reazioni di tipo allergico | Let your doctor know as soon as possible, as your treatment may need to be changed |
Importante: if you develop an itchy rash, a swollen face or mouth, or have difficulty breathing, these can be signs that you are allergic to the antibiotic. Do not take any more cefradine and speak with your doctor or go to your local accident and emergency department straightaway.
If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist for further advice.
