12 reviews for Cephalexin (Keflex)
Keflex contains Cephalexin.
Cephalexin (also spelled cefalexin) is an antibiotic from a group called cephalosporins. It has been used safely for many years to treat common infections caused by bacteria.
It is often chosen for skin, bone, ear, throat, chest and urinary infections, and it is a common choice for skin infections such as cellulitis.
What is it used for?
- Skin and soft tissue infections, such as cellulitis and infected wounds
- Urinary tract infections
- Throat, ear and chest infections
- Bone infections
How does it work?
Cephalexin stops bacteria from building their protective outer wall. Without it, the bacteria break apart and die, and your body can clear the infection.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- Do not take it if you have ever had an allergic reaction to this antibiotic or to a similar one.
- Antibiotics only work on infections caused by bacteria. They do not help colds, flu or most sore throats, which are caused by viruses.
- Take the whole course your doctor gives you, even if you feel better after a few days. Stopping early can let the infection come back and make germs harder to treat in the future.
- Tell your doctor if you are pregnant, trying for a baby or breastfeeding.
- Never share your antibiotics or keep leftovers for another time.
- Tell your doctor if you are allergic to penicillin. A small number of people who are allergic to penicillin also react to this type of antibiotic.
- Tell your doctor if you have kidney problems or have ever had bowel problems such as colitis.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Keflex can cause side effects, but not everybody gets them.
Common side effects
- Feeling sick (nausea) or being sick
- Diarrhoea or loose stools
- Stomach ache or indigestion
- Headache
- Thrush (a yeast infection) in the mouth or vagina
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Severe diarrhoea that is watery or has blood in it, even up to 2 months after you finish the medicine
- Signs of an allergic reaction, such as a rash, swelling of the face, lips or tongue, wheezing or trouble breathing
- A skin rash that blisters or peels, with fever and sore mouth or eyes
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it exactly as your doctor tells you, usually 2 to 4 times a day, spaced evenly.
- Swallow the capsule or tablet with a glass of water. You can take it with or without food.
- A common adult dose is 250 mg to 500 mg every 6 hours, or 500 mg every 12 hours.
- Most courses last 7 to 14 days. Keep taking it until the course is finished.
If you miss a dose: Take it as soon as you remember. If it is nearly time for your next dose, skip the missed one and carry on as normal. Never take two doses at once to make up.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
- QHow soon will Keflex work?
- A
Most people feel better within 2 to 3 days. Tell your doctor if you are not improving after 3 days.
- QCan I take Keflex with food?
- A
Yes. You can take it with or without food. Taking it with food may help if it upsets your stomach.
- QCan I drink alcohol with Keflex?
- A
Alcohol does not stop cephalexin working, but it is best to avoid it while you are fighting an infection.
