Description
Apomorphine injection is used alone or together with other medicines to treat hypomobility, “off” episodes (“end-of-dose wearing off” and unpredictable “on/off” episodes) in patients with advanced Parkinson's disease, sometimes referred to as "shaking palsy." By improving muscle control and reducing stiffness, this medicine allows more normal movements of the body as the disease symptoms are reduced.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:

Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of apomorphine injection in the pediatric population. Safety and efficacy have not been established.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of apomorphine injection in the elderly. However, elderly patients are more likely to have serious unwanted effects (eg, confusion, hallucination, heart or blood vessel problems, falls, stomach or bowel problems, lung or breathing problems), which may require caution in patients receiving this medicine.
