Interferon beta-1a injection is used to treat the relapsing forms of multiple sclerosis (MS). Interferon beta-1a will not cure MS, but it may slow some of the disabling effects and decrease the number of relapses of the disease. Interferons are natural substances that are produced in the body to help fight infections. Interferon beta-1a is a synthetic (man-made) version of these substances.

Interferon beta-1a is available only with your doctor's prescription.

Parcopa is a combination medicine used to treat symptoms of Parkinson's disease, such as muscle stiffness, tremors, spasms, and poor muscle control. Parkinson's disease may be caused by low levels of a chemical called dopamine (DOE pa meen) in the brain.

Levodopa is converted to dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect.

Parcopa is also used to treat Parkinson symptoms caused by carbon monoxide poisoning or manganese intoxication.

Parcopa may also be used for purposes not listed in this medication guide.
