If muscle tightness or spasticity is getting in the way of daily life, baclofen is one of the common medicines doctors prescribe. It relaxes muscles by acting on the spinal cord and brain to reduce nerve signals that cause spasms. Doctors most often use it for spasticity from spinal cord injury, multiple sclerosis, or certain neurologic conditions.
Baclofen comes as oral tablets and, in severe cases, as an intrathecal pump delivery directly into the spinal fluid. The oral form helps many people, but the pump is reserved for those who don't get enough benefit or who have bad side effects from pills.
How to take baclofen safely
Most adults start with a low dose—commonly 5 mg three times a day—and the doctor increases it slowly. Typical dosing rises in small steps every few days until symptoms improve. Many people stay on 30–80 mg daily, split across the day. Your provider will pick a dose based on how you respond and any side effects.
Take baclofen exactly as prescribed. You can take it with or without food. If it causes stomach upset, try taking it with a meal. If you miss a dose, take it when you remember unless it's close to the next dose—don't double up.
If you have kidney problems, your doctor will likely use a lower dose. Older adults often start lower too. Driving or using heavy machinery can be risky until you know how baclofen affects you, since it can cause drowsiness and slower reflexes.
Side effects, warnings and withdrawal
Common side effects are drowsiness, weakness, dizziness, nausea, and lightheadedness. These usually lessen as your body adjusts. Serious problems are rare but can include confusion, breathing issues, or severe low blood pressure—seek medical help if these happen.
Don’t mix baclofen with alcohol, strong sedatives, benzodiazepines, or high-dose opioids unless your doctor says it’s safe. The combo can dangerously depress breathing and alertness.
A key safety point: never stop baclofen suddenly. Abruptly stopping can cause withdrawal symptoms like hallucinations, severe anxiety, fast heartbeat, fever, or even seizures. Your doctor will give a taper plan to lower the dose gradually if it’s time to stop.
Alternatives include tizanidine, benzodiazepines (short term), botulinum toxin for focal spasticity, or intrathecal baclofen for severe cases. Each option has its own risks and benefits, so talk through them with your clinician.
If you’re starting baclofen, ask your provider about expected benefits, how long to try the medicine, and a clear plan for dose changes or stopping. Keep an updated list of all your meds and share it with anyone who treats you—interactions matter. That simple step makes your treatment safer and more effective.
