Cephalexin (Keflex®, Biocef®) is a medication used for treating various types of bacterial infections, including respiratory tract infections, sinus infections, and urinary tract infections. It is also approved to prevent heart valve infections.
The medicine comes in the form of capsules and an oral solution. Cephalexin is usually taken two to four times a day, depending on your healthcare provider's instructions. It does not matter what time of day you take cephalexin, as long as you take it at the same times each day (to maintain an even level of medication in your blood). It is important that you complete your entire prescription, even if you start feeling better; this will ensure that the infection is completely treated.
As with any medicine, side effects are possible with cephalexin. However, not everyone who takes the drug will experience side effects. In most cases, if side effects do occur, they are minor and either require no treatment or can be treated easily by your healthcare provider. Common side effects of cephalexin include, but are not limited to:
- Upset stomach (dyspepsia)
- Unexplained rash
- Yeast infection.
