Summary
Baclofen is used to treat muscle spasticity, which is when muscles are continuously contracted. This often occurs due to conditions like multiple sclerosis, which is a disease affecting the brain and spinal cord, or spinal cord injuries. It helps relax muscles, reducing spasms and improving mobility.
Baclofen works by acting on the central nervous system, which includes the brain and spinal cord, to relax muscles. It mimics the action of GABA, which is a neurotransmitter that reduces nerve activity, helping to decrease muscle spasms and improve mobility.
Baclofen is usually taken orally in tablet form, three times a day, with or without food. The starting dose is typically 5 mg, which may be gradually increased by 5 mg every three days until the desired effect is achieved. The maximum recommended dose is 80 mg per day.
Common side effects of Baclofen include drowsiness, which is feeling unusually sleepy, and dizziness, which is feeling lightheaded. These effects occur in more than 10% of people taking Baclofen and are usually mild to moderate in severity.
Baclofen can cause drowsiness and dizziness, affecting your ability to drive or operate machinery. Stopping Baclofen suddenly can lead to withdrawal symptoms like hallucinations, which are seeing or hearing things that aren't there, and seizures, which are sudden, uncontrolled electrical disturbances in the brain. Always follow your doctor's instructions.
