You may need to be more closely monitored, and the amount of
Haloperidol tablets you take may have to be altered. If you are not sure if
any of the above apply to you, talk to your pharmacist before taking
Haloperidol tablets.
Medical check ups
Your doctor may want to take an electrocardiogram (ECG) before or
during your treatment with Haloperidol tablets. The ECG measures the
electrical activity of your heart.
Blood tests
Your doctor may want to check the levels of minerals (electrolytes) in
your blood.
If you suffer from a disorder with related memory loss, you should talk
first to your doctor, who will decide if you can be given Haloperidol and
will explain the possible risks of its use.

These are signs of serious conditions.
DO NOT take Haloperidol if you are taking:
• certain other medicines which can affect the heart e.g. quinidine,
bretylium, disopyramide, procainamide, amiodarone, sotalol, dofetilide.
