3 How to take

Always take Co-tenidone tablets exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist.

Swallow the tablets with water.

Usual doses:

   Adults: 1 tablet a day

   Children: Not recommended

If you are elderly or have impaired kidney function, your doctor may prescribe you a different dose.

Overdose causes an excessively slowed heart beat and low blood pressure with feeling sick, difficulty breathing, weakness, dizziness, increased production of urine and changes in the levels of certain chemicals in the body.

If you forget to take to take the tablets

If you forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose. Then go on as before. Never double up on the next dose to make up for the one missed.

If you stop taking the tablets

Do not stop treatment early, especially if you have ischaemic heart disease. Talk to your doctor before you stop taking the tablets and follow their advice.
