Dosage and how to use fusidic acid
Fusidic acid comes as a cream, an ointment or eye drops.
The main difference between fusidic acid cream and ointment is how it feels. The ointment is greasier than the cream.
Dose for cream and ointment
Whether you're using cream or ointment, you'll usually put it on 3 or 4 times a day.
If you are using a cream which also contains a steroid, you'll usually put it on twice a day.
If you have been told to cover the infected skin with any dressings or bandages, including a nappy if you are using it on a baby, you may not need to use the medicine so often. Follow your doctor's advice.
Check with your pharmacist or doctor if you're unsure.
Dose for eye drops
Fusidic acid eye drops come as a gel in a tube. As the gel touches your eye it becomes runnier.
You'll usually put 1 drop into your eye twice a day, once in the morning and once in the evening.
