Frequently Asked Questions (FAQs)


Q: What else should I know before taking Baclofen?

A: Baclofen should not be used in all patients. People suffering a handicap (unable to move or perform a function) due to muscle tension and pain (spasm) will benefit the most from this medicine. Baclofen is not suitable for children below 33kg of weight. Baclofen must be taken with food or meal, preferably at night-time to benefit from painful night cramps. If you are performing any tasks such as exercise, walking, etc., Baclofen should be taken an hour before the task.

Q: Can I use Baclofen as a painkiller to relieve any pain?

  • Baclofen is a muscle relaxant and not a pain killer. It relieves pain only in conditions that are generated due to nerve injury or involvement.
  • It helps to reduce tension and stiffness of muscles inducing pain. Hence Baclofen should be used in painful conditions due to a problem in the brain or spinal cord and under medical supervision. Do not self-medicate with Baclofen.
