Keflex® (cephalexin) is a prescription medicine that belongs to a class of antibiotics called cephalosporins. It is approved to prevent heart valve infections and is also commonly used for treating bacterial infections, such as urinary tract infections and sinus infections.
Keflex works by preventing bacteria from making and maintaining their cell wall. Without a cell wall, bacteria are vulnerable and ultimately die. As a result, the infection is kept from spreading within the body. Keflex is typically taken two to four times daily, depending on your healthcare provider's instructions.
Before you start taking Keflex, safety information for the antibiotic should be reviewed with your healthcare provider. This drug may not be suitable or safe for everyone, so it is important to talk to your healthcare provider before starting treatment if you are pregnant or breastfeeding, have kidney disease, or will be having surgery.
It is also important to be aware of the potential side effects of Keflex; side effects that have been reported with this medication include dizziness, upset stomach, and nausea.
