Keflex 500 mg Capsule

Keflex 500 mg Capsule is a prescription antibiotic that contains 500 mg of cefalexin in each capsule. It belongs to the cephalosporin class of antibiotics and is used to treat certain bacterial infections, not viral illnesses like colds or flu. Keflex 500 mg Capsule is commonly prescribed for infections of the skin, ears, throat, and urinary tract when the bacteria are expected to be sensitive to cefalexin. This Eli Lilly Pharmaceuticals product is supplied as a strip/box of 10 capsules.

How it works: Cefalexin works by interfering with the way bacteria build their cell walls, which weakens and kills susceptible bacteria. The capsule form delivers the medicine by mouth, so it is absorbed after swallowing and begins working throughout the body against the infection.

Keflex 500 mg Capsule is a higher-strength capsule option, which can make it useful when a doctor wants to give 500 mg in a single dose rather than using more than one lower-strength capsule. Because there are no other strengths or forms listed here, this product fits standard adult dosing plans where a 500 mg capsule is a convenient way to reach the prescribed amount. The exact schedule depends on the infection being treated and the prescriber’s instructions.

• Skin infections
• Ear infections
• Throat and tonsil infections
• Urinary tract infections
• Respiratory tract bacterial infections

• Swallow the Keflex 500 mg Capsule whole with a glass of water.
• Take it exactly as prescribed, at evenly spaced times if your doctor has set multiple daily doses.
• You may take Keflex 500 mg Capsule with or without food if stomach upset occurs.
• Do not open, crush, or chew the capsule unless your doctor or pharmacist tells you to.
• Finish the full prescribed course even if you feel better before it is done.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.

Each Keflex 500 mg Capsule provides 500 mg of cefalexin. Depending on the infection, a doctor may prescribe it 2, 3, or 4 times a day, and the maximum daily amount is determined by the prescriber based on the condition being treated and the patient’s needs. Do not change the dose or frequency on your own, since this strength is intended for use only in the schedule your doctor chooses.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Cefalexin may include:

• Nausea
• Diarrhea
• Stomach pain
• Vomiting
• Headache

• Tell your doctor if you have ever had an allergy to cephalosporin or penicillin antibiotics.
• Use caution if you have kidney disease, because cefalexin doses may need adjustment.
• Keflex 500 mg Capsule may not be the right choice if you have a history of severe antibiotic-associated diarrhea.
• Take the capsule exactly as directed; higher-strength 500 mg capsules are not meant to be split or used differently without medical advice.
• Tell your prescriber about all medicines you take, including blood thinners and probenecid.
• Avoid using this antibiotic for viral infections, since it only works against bacteria.
