What are the possible side effects of baclofen (Lioresal)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any of these serious side effects:

• seizure (convulsions);
• confusion, hallucinations; or
• an uneven heartbeat.

• drowsiness, dizziness, weakness, tired feeling;

What is the most important information I should know about baclofen (Lioresal)?

Baclofen can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol. It can increase some of the side effects of baclofen.

Do not use baclofen at a time when muscle tone is needed to assure safe balance and movement for certain activities. In some situations, it may endanger your physical safety to be in a state of reduced muscle tone.

You may have withdrawal symptoms such as seizures or hallucinations, when you stop using baclofen after using it over a long period of time. Do not stop using this medication suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.
