Baclofen is a muscle relaxant that works by suppressing the transmission of certain messages between nerve cells. It can therefore be used for relieving the pain of muscle spasms including chronic severe spasticity. Baclofen may also be used for the treatment of gastroesophageal reflux (GERD), intractable hiccups, and trigeminal neuralgia
Baclofen can be taken by mouth as tablets or by intrathecal injection.
If you are taking it for relieving the pain of muscle spasms, you should take 5-10 mg 3 times daily.
If you are taking it for treating chronic severe spasticity, you should start with 5 mg 3 times daily and gradually increase up to a maintenance dose of 60 mg daily in divided doses. Your doctor will review the treatment if no benefit is observed in 6 weeks on the maximum dose, which is 100 mg daily.
If you are taking it for relieving hiccups due to gastric distension, you should take 5 mg twice daily.
For the doses administered by intrathecal injection, your doctor will adjust them according to your condition and response.
Common side effects of Baclofen include confusion, dizziness, drowsiness, and dry mouth, hallucination. Baclofen should not be stopped abruptly since this may cause seizures and hallucinations.
