Apomorphine, which is also known as Apokyn, is indicated for the treatment of advanced Parkinson's disease. This treatment is especially used when muscle stiffness and loss of muscle control happen as a result of a decreased response to anti-Parkinson drugs. As a matter of fact, Apomorphine shares some of the effects associated with a chemical called dopamine, which in turn occurs naturally in the human body. As explained by netdoctor.co.uk, “Dopamine normally transmits messages by stimulating specific receptor sites in the brain. Apomorphine works by stimulating these same receptor sites. In this way, Apomorphine helps to restore the dopamine activity in the brain, which helps reduce the symptoms of Parkinson's disease”. Bear in mind that one of the causes of Parkinson's disease is the low levels of dopamine in the brain. Before using Apomorphine, you must tell your healthcare provider about the other medicines that you may be using, because “serious drug interactions can occur when certain medicines are used together with apomorphine.”(as stated by “everydayhealth.com”). You should also tell them if you’ve ever had certain medical issues that may potentially compromise the effectiveness of this treatment, namely heart disease, low blood pressure, liver disease, kidney disease, or if you have a history of mental illness. When it comes to the common side effects of Apomorphine, they include swelling, confusion, yawning, and itching. To make sure that this medication will be safe for you during pregnancy, you need to tell your doctor if you are pregnant or if you plan on becoming pregnant before using it.
