How to take it

How much to take

The dose of Rythmodan may be different for each person. Your doctor will decide the right dose for you.

How to take it

Swallow Rythmodan whole with plenty of fluid.
The daily dose of Rythmodan is usually taken in three equally divided doses.

When to take it

Take Rythmodan at about the same time each day.
Taking your capsules at the same time each day will have the best effect. It will also help you remember when to take your medicine.
It does not matter if you take Rythmodan before or after food.
This medicine works best when there is a constant amount in the blood. To help keep the amount constant it is best to take the doses at evenly spaced intervals day and night.

How long to take it

Rythmodan helps control your condition, but does not cure it. Therefore you must take Rythmodan every day. Continue taking the capsules for as long as your doctor or pharmacist tells you.
Do not stop taking your capsules because you are feeling better.

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 try to make up for a missed dose by taking more than one dose at a time.
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 pharmacist or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much Rythmodan. Do this even if there are no signs of discomfort or poisoning.
