Keflex, the brand name of cephalexin, is a prescription medication that belongs to a class of antibiotics called the cephalosporins. Keflex is used for the treatment of bacterial infections such as respiratory tract infections, inner ear infection, skin and skin structure infections, urinary tract infection, genital tract infections and bone infections. It may also be given to prevent endocarditis, which is an infection of the walls of the heart. Keflex prevents the replication of bacteria in the body; as a result, the bacteria will eventually die. Keflex has the potential to produce many side effects that should be discussed with a health care provider.
Dizziness and Headache
Patients on Keflex may experience dizziness. This may also lead to confusion or agitation. Operating a vehicle or heavy machinery should be avoided. Headache is another side effect that may also be seen in users of Keflex. Pain relievers such as acetaminophen and ibuprofen can treat the headache; a physician or pharmacist can help in choosing the best one to use.These side effects should diminish as the body adjusts to the new drug. If symptoms worsen or do not decrease with time, a physician should be consulted.
Diarrhea
Diarrhea is another common side effect reported by users of Keflex. Drinking plenty of fluids and avoiding large fatty meals may help patients alleviate this undesired side effect. If diarrhea worsens or contains blood, the patient should contact a health care provider immediately. If diarrhea is accompanied by fever, the patient may have an infection and requires further medical help.
Nausea
Nausea is another side effect that occurs with the administration of Keflex. According to the "Drug Information Handbook," vomiting can occur with this medication as well. To avoid these adverse effects, the patient should eat small frequent meals and avoid fatty meals. Patients may also find that sucking on hard candy helps. If these side effects worsen, the individual should seek medical help as soon as possible.
