How to take it

How much to take

Your doctor will tell you how many tablets you need to take each day. This depends on your age, your condition and whether or not you are taking any other medicines.

Your doctor may recommend that you start with a low dose and slowly increase the dose to the lowest amount needed to control your condition.

Ask your doctor if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow all directions given to you by your doctor and pharmacist carefully. If you take the wrong dose, APO-SODIUM VALPROATE may not work well.

How to take it

Swallow the tablets whole with a full glass of water or other liquid.

Do not crush or chew the tablets. APO-SODIUM VALPROATE tablets have a special coating to stop them dissolving until they have gone through the intestines. If you crush or chew the tablets, the coating is destroyed and they will not work as well.

When to take it

Take APO-SODIUM VALPROATE at about the same time each day. This will have the best effect and also help you remember when to take it.

If you are not sure when to take it, ask your doctor.

If you forget to take it

Always remember to take your prescribed dose, otherwise you may find that either your seizures or manic symptoms may return.

If you forget a dose, take your next dose as usual. Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting unwanted side effects.

Ask your doctor or pharmacist if you are not sure what to do.

Ask your pharmacist for hints if you have trouble remembering when to take your medicine.

How long to take it

Keep taking APO-SODIUM VALPROATE for as long as your doctor recommends. This medicine helps control your condition but does not cure it. To properly control your condition, it must be taken regularly.

If you take too much (overdose)

APO-SODIUM VALPROATE should have little effect on the oral contraceptive pill, however tell your doctor if you are taking it.
