While you are taking ZALDIAR

Things you must do

Before starting any new medicine, tell your doctor or pharmacist that you are taking ZALDIAR.

If you become pregnant while taking ZALDIAR tell your doctor.

Keep all your doctor’s appointments so that your progress can be checked.

Tell your doctor if you feel the dose you are taking is too strong or too weak. If the dose is too strong you may feel very drowsy or have difficulty breathing.

If the dose is too weak you may continue to feel some pain between doses.

Things you must not do

Do not stop taking ZALDIAR, or change the dose, without checking with your doctor. On rare occasions, especially if you have been taking Zaldiar for a while stopping treatment abruptly can make you feel unwell.

Do not take ZALDIAR to treat any other conditions unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how ZALDIAR affects you. It may cause dizziness and drowsiness in some people. Make sure you know how you react to Zaldiar before you drive a car, or do anything else that could be dangerous if you are dizzy.

This effect may be made worse by drinking alcohol or some other medicines that act on the central nervous system.

You can become addicted to Zaldiar even if you take it exactly as prescribed. Zaldiar may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.

As with all other opioid containing products, your body may become used to you taking Zaldiar. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking Zaldiar suddenly, so it is important to take it exactly as directed by your doctor.

Tolerance to Zaldiar may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking ZALDIAR.
