Why is Keflex prescribed?
Keflex and Keftab are cephalosporin antibiotics. They are prescribed
for bacterial infections of the respiratory tract, the middle ear,
the bones, the skin, and the reproductive and urinary systems. Because
they are effective for only certain types of bacterial infections,
before beginning treatment your doctor may perform tests to identify
the organisms causing the infection.
Keflex is available in capsules and an oral suspension form for use
in children. Keftab, available only in tablet form, is prescribed exclusively
for adults.
Most important fact about Keflex
If you are allergic to either penicillin or cephalosporin antibiotics
in any form, consult your doctor before taking Keflex. There is a possibility

occurs, it could be extremely severe. If you take the drug and feel
signs of a reaction, seek medical attention immediately.

Take Keflex at even intervals around the clock as prescribed by your
doctor.If you are taking the liquid form of Keflex, use the specially
marked spoon to measure each dose accurately.
Your doctor will only prescribe Keflex to treat a bacterial infection;
it will not cure a viral infection, such as the common cold. It's important
to take the full dosage schedule of Keflex, even if you're feeling
better in a few days. Not completing the full dosage schedule may decrease
the drug's effectiveness and increase the chances that the bacteria
