Why is Cefalexin prescribed?
Cefalexin/Cephalexin is a cephalosporin antibiotic used to treat certain infections caused by bacteria such as pneumonia and bone, ear, skin, and urinary tract infections. Antibiotics will not work for colds, flu, or other viral infections.
Cefalexin is sometimes prescribed for other uses; ask your doctor for more information.
How should Cefalexin be used?
Cefalexin/Cephalexin may come as a capsule, tablet, and liquid to take by mouth. It is usually taken every 6 hours (four times a day) or every 12 hours (twice a day) for 7 to 10 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cephalexin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake the liquid well before each use to mix the medication evenly. The capsules and tablets should be swallowed whole and taken with a full glass of water. Continue to take cephalexin even if you feel well. Do not stop taking cephalexin without talking to your doctor.
What special precautions to follow?
Before taking Cefalexin/cephalexin,
- inform your doctor if you are allergic to cephalexin or any other cephalosporin antibiotic such as cefadroxil or cephradine, penicillin, or any other drugs.
- inform your doctor what prescription and nonprescription medications you are taking, especially other antibiotics, anticoagulants such as warfarin, probenecid, and vitamins.
- inform your doctor if you have or have ever had kidney or liver disease, colitis, or stomach problems.
- inform your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking cephalexin, consult your doctor.
- if you are having surgery, including dental surgery, inform the doctor or dentist that you are taking cephalexin.
- What special dietary instructions to follow?
- Cephalexin may cause an upset stomach. Take cephalexin with food or milk.
What to do if I forget a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What side effects can Cefalexin cause?
Cefalexin/Cephalexin may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- upset stomach
- mild skin rash
If you experience any of the following symptoms, consult your doctor immediately:
- severe skin rash
- difficulty breathing or swallowing
- unusual bleeding or bruising
- sore throat
- painful mouth or throat sores
- vaginal infection
Cefalexin/Cephalexin may cause other side effects. Consult your doctor if you have any unusual problems while taking this.
What other information to know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to Cefalexin.
Do not let anyone else use your medication. If you still have symptoms and need further treatment, consult your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
