Baclofen

Baclofen is a muscle relaxant. It is used to improve the symptoms of muscle stiffness and spasms due to injuries to your spinal cord. It also helps to ease your pain and improve your movements.

Baclofen may be used for other conditions. Check with your healthcare professional if you are unsure why you are given this medication.

• Baclofen may be taken with or after food.
• Take your medication according to the instructions stated on the medication label.
• If you have been told by your doctor to take baclofen regularly, it may take around three to four days before you can feel its full benefits. You should not stop taking this medication even if you do not feel better at the beginning. Continue to take this medication even after you feel better to prevent your symptoms from returning.
• Do not stop taking or adjust the dose of this medication without checking with your doctor. You may experience unpleasant effects such as muscle stiffness, cramps, fast heart rate, fever, confusion or seizures (fits) if you stop taking baclofen suddenly.
• Do check with your doctor on how long you will have to be on this medication.

• If you have been told by your doctor to take Baclofen regularly but you forget to take a dose, take it as soon as you remember. However, if more than half of the time to the next dose has passed, skip the missed dose and take the next dose at your usual timing.
• For example, for a medication to be taken two times daily at 8am and 8pm, and you missed your first dose at 8am, skip the first dose if it is after 2pm, and take your second dose at the usual timing at 8pm. Do not take two doses to make up for the missed dose.
