Mirapex ER and Prevymis

• Generic Name: pramipexole
• Dosage Forms: tablet, extended release
• Other Brand Names: Mirapex, Mirapex ER

Mirapex ER has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson's disease.

Mirapex ER is used to treat symptoms of Parkinson's disease (stiffness, tremors, muscle spasms, and poor muscle control). This medicine is also used to treat restless legs syndrome (RLS).

Only immediate-release Mirapex ER (Mirapex) is approved to treat either Parkinson symptoms or RLS. Extended-release this medicine (Mirapex ER) is approved only to treat Parkinson symptoms.

Parkinson's and RLS are two separate disorders. Having one of these conditions will not cause you to have the other condition.

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

• Generic Name: letermovir
• Dosage Forms: tablet, film coated
• Other Brand Names: Prevymis

Prevymis (letermovir) is an antiviral medicine used to help prevent cytomegalovirus (CMV) infection after a stem cell (bone marrow) transplant from a donor.

Prevymis is for use in adults who are seropositive for CMV. Seropositive means that the virus is in your blood even if you do not show any symptoms of infection.

A CMV-seropositive person is at risk for "reactivation" of the virus if the immune system becomes weak. While normally treatable, CMV infection can be serious in people undergoing a stem cell transplant.

Prevymis comes as a tablet or can be given by your doctor through an IV line (intravenously).
