What Is Lioresal Intrathecal Used For?

Lioresal Intrathecal is a specialized muscle relaxant that contains baclofen. It’s used when oral medications don’t work well enough or cause too many side effects.

Primary Uses

This medication reduces tension in muscles that causes spasms. It’s used to treat muscle spasms that occur in conditions like multiple sclerosis, cerebral palsy, and other diseases or injuries affecting the spinal cord or brain.

How It Works

Lioresal Intrathecal reduces muscle spasms and the pain that comes with them. It helps improve your mobility and ability to manage daily activities by delivering medication directly to your spinal cord through an implanted pump.

Good to know: This treatment can significantly improve your mobility and help you better manage your daily activities.

How to Take Lioresal Intrathecal

This medication can only be given by experienced doctors using special medical equipment. You’ll need to stay in the hospital, at least at the beginning of treatment.

Treatment Process

First, your doctor will inject a small amount into your spinal cord to test if it improves your muscle spasms. If successful, a special pump will be surgically implanted under the skin of your abdomen. The pump delivers a constant amount of medication into your spinal cord through a tiny tube. It may take several days to find the right dose for you.

Home Care

You or your caregiver will be taught how to care for the pump at home and keep the implant site free from infection. You’ll need regular doctor visits to check progress, adjust doses, and refill the pump.

Important: Never let the pump run out of medication or stop treatment suddenly – this can cause serious, potentially life-threatening withdrawal symptoms.
