What is Keflex?

Keflex is an antibiotic medication that contains cephalexin or cefalexin. Cephalexin works in a similar way to penicillin antibiotics. It attacks the bacteria that cause the infection and prevents them from forming cell walls. Without a cell wall, the bacteria are unable to survive. In this way Keflex reduces the number of bacteria at the site of infection allowing the symptoms to clear up. Some bacteria are able to develop a defence mechanism that protects them from the effects of antibiotics, especially from the penicillin drugs. Keflex is particularly useful against infections that have become resistant to penicillin treatment. It is used to treat a wide range of bacterial diseases, including lung, middle ear, bladder, skin, prostate, and dental infections.

How to use Keflex?

Keflex is provided as tablets or capsules that are available in 250 and 500 mg dose strengths. The dose of Keflex will depend on the type of infection you have. Most infections in adults are treated with two to four doses of Keflex taken each day for between 5 and 7 days. We will let you know the appropriate dose for you.

Keflex can be taken before, during or after meals. Always try and space the doses evenly through the day, and always take the complete course that has been prescribed even if your symptoms disappear in the first few days. If you do not complete the full course there is a risk that the infection may come back. If you forget a dose, take a tablet or capsule as soon as you remember. If it is almost time for the next dose then it is recommended that you skip the missed dose. If you take two tablets or capsules at once you will increase the risk of side effects.

Who can use Keflex?

If you complete a consultation form we can tell you if Keflex is appropriate for you. We will not be able to prescribe Keflex if you are allergic to this type of antibiotic. Other types of medicines may be affected by taking Keflex, and the dose of Keflex may need to be adjusted if you have kidney problems. We will be able to assess this once we have all your details.

Keflex side effects

The most common side effects of Keflex are diarrhoea and stomach upsets. However, not everyone experiences these problems. If you get diarrhoea or vomiting drink plenty of water to replace lost fluids. Also consider using condoms in addition to oral contraceptives until the vomiting or diarrhoea have cleared up. This is necessary because the levels of hormones in your bloodstream may fall below the levels that provide effective contraception. Some people develop oral or vaginal thrush after taking a course of antibiotics. If this occurs ask us for advice. You should contact us immediately if you get a severe skin rash, or if you become jaundiced with yellow skin and have fever and joint pain. Also make an urgent appointment if you experience swelling of the tongue, mouth or face, or if you have prolonged and severe diarrhoea.
