Dear Terry Kempf- My name is Dominic Marchese, RPh., I am a pharmacist with Athena's Partnership for Care Program. Athena Rx Home Pharmacy has created a program to address the educational needs of patients with Parkinson's. I attend support groups of neurological patients throughout the state of Ohio, Pennsylvania, and Kentucky. We have other pharmacist throughout the country that also perform this role. If you would to learn more about our program. Please call 1-800-5-ATHENA and ask for Peter Paolucci. Let Peter know I referred you to him. If you would like to contact me directly please, call me at 1-800-537-8899 ext 6104. I am sorry to hear that you have fallen last week. Based upon the information that you have presented, I believe that your blood pressure was too low. This attributing factor was most likely caused by the combination of Sinemet, which is known to cause low blood pressure and Artane. Our blood pressure regulates the amount of oxygen that enters into our brain. If our pressure is too low not enough oxygen travels up to the brain and we become lightheaded and may faint or fall. I would recommend that you have your blood pressure taken as soon as possible and to notify your neurologist and your primary care physician. Some patients who experience the same symptoms are placed on medication, in conjunction with Sinemet, to help raise their blood pressure to allow more oxygen to reach the brain. This is important to discuss with your doctor. I hope I could answer your question. I welcome the opportunity to speak with you directly. Please feel free to call me if you need additional information. Dominic Marchese, RPh. Athena Rx Home Pharmacy 1-800-5-ATHENA
