What Tinasil tablets are used for
Tinasil tablets are used to treat fungal infections of the:
- fingernails and toenails
- groin and body caused by tinea (ringworm)
- feet caused by tinea, commonly called "Athlete's foot".
These infections are caused by a group of fungi called dermatophytes.
Terbinafine, the active ingredient in Tinasil tablets, works by killing the dermatophytes.
Tinasil tablets are usually taken when a fungal infection of the skin or nails does not respond to treatment with creams or gels, when the infection is severe and the affected area is large.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

How to take Tinasil tablets
Follow carefully all directions given to you by your doctor and pharmacist. These directions may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
The usual dose of Tinasil is one tablet (250 mg) each day. If you have kidney problems, your doctor may reduce the dose to half a tablet each day.
How to take it
Swallow the tablet with a full glass of water.
If your doctor has advised that you take half a tablet, you may divide the tablet in half along the breakline.
If you find that Tinasil upsets your stomach, try taking it immediately after a light meal.
Take Tinasil at about the same time each day. Taking your tablet at the same time each day will have the best effect. It will also help you remember when to take it.
How long to take it
The length of your treatment will depend on the type of infection you have, what part of the body is affected and how well you respond to treatment.
Fungal skin infections (tinea):
If you have a tinea infection of the feet (Athlete's foot), you will usually take Tinasil tablets for 2 to 6 weeks.
If you have a tinea infection of the body or groin, you will usually take the tablets for 2 to 4 weeks.
The signs and symptoms of infection may last for several weeks after the fungi (dermatophytes) have been killed.
Fungal nail infections:
Fungal nail infections usually take longer to heal than fungal skin infections. You will usually take the tablets for anywhere from 6 weeks to 3 months. But, if you have a nail infection of the big toe or your nails grow very slowly, you may need to take the tablets for up to 6 months.
It may take several months after you stop taking Tinasil for your nail to look completely normal. That is because the deformed part of the nail has to grow out and be replaced by a healthy nail.
If you forget to take it
If it is almost time for your next dose (within 4 hours), skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone number 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Tinasil tablets. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Some of the symptoms of an overdose may include headache, nausea (feeling sick), stomach pain and dizziness.
