|3 How to take Mezatil

Always take Mezatil exactly as your doctor has told you. Read and follow the instructions on the pharmacist's label. You should check with your doctor or pharmacist if you are not sure about anything.

Your medicine comes in a sustained-release capsule which means the drug is released over a longer period of time.

■    Mezatil capsules are for oral use

■    The capsules should be taken whole with some water

■    Do not suck or chew the capsules

■    Do not stop taking the medicine without speaking to your doctor first

Adults

The initial dose is normally 90mg taken twice a day. Your doctor may decide to increase this to 180mg twice a day.

Elderly people and patients with liver or kidney problems

The initial dose should be 60mg taken twice a day. Your doctor may increase the dose slowly to achieve the required level of control. The daily dose should not exceed 90mg twice a day.

Children

Children should not take this medicine.

If you take more Mezatil than you should

Do not exceed the dose prescribed to you by your doctor. If a child takes any capsules or if you accidentally take more than the prescribed dose, seek medical advice immediately and take your medicine and this leaflet with you. Exceeding the correct dose may cause your blood pressure to become too low, which may lead to collapse, slow heart beat and/or an irregular heart beat. It may also cause an increase in blood sugar levels (hyperglycaemia).

If you forget to take Mezatil

Try and take your Mezatil Capsules at the same time each day. If you forget to take a dose, take it as soon as you remember.
