4. How do I take TINASIL?

How much to take

Follow your doctor's instructions on how many TINASIL tablets to take.
The usual dose of TINASIL is one tablet (250 mg) each day. If you have kidney problems, the dose may be reduced to one-half a tablet each day.

When to take TINASIL

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 to take TINASIL

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.

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. Your doctor will advise you regarding the duration of 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 your fungal infection does not improve. Your doctor will review and determine if an alternative antifungal therapy is needed.

If you forget to take TINASIL

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 when to take your medicine, ask your pharmacist for some hints.

If you take too much TINASIL

contact your doctor, or
go to the Emergency Department at your nearest hospital.

5. What should I know while taking TINASIL?
