Summary
Flucloxacillin is used to treat bacterial infections, which are illnesses caused by harmful bacteria. It's especially effective against infections caused by staphylococci, which are a type of bacteria. Common uses include treating skin infections, respiratory tract infections, and bone infections.
Flucloxacillin works by interfering with the bacteria's cell wall formation, which is the protective layer around the bacteria. This action causes the bacteria to die, helping to clear the infection from your body.
The usual adult dose of flucloxacillin is 250 mg to 500 mg taken every six hours. It's important to take it on an empty stomach, which means either one hour before or two hours after meals, to help your body absorb it better.
Common side effects of flucloxacillin include nausea, which is feeling sick to your stomach, diarrhea, which is loose or watery stools, and skin rash, which is an area of irritated or swollen skin. These effects are usually mild and temporary.
Flucloxacillin can cause liver problems, especially in older adults or those taking it for more than two weeks. Watch for symptoms like yellowing of the skin or eyes, which is jaundice, and seek medical help immediately if they occur.
