Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Cardiovascular effects: The cardiovascular system (heart and blood vessels) may be affected by the use of brimonidine. When brimonidine causes the blood vessels in the skin to narrow, it can also have this effect on other blood vessels in the body. If you have a history of heart attack, angina, stroke or other conditions that can be worsened if the blood supply is reduced, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: The kidneys are responsible for removing brimonidine from the body. Although studies have not been done to show this, it is possible that kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Brimonidine is broken down by the liver so it may be removed from the body. Although studies have not been done to demonstrate how liver disease or reduced liver function affects brimonidine, it is possible that liver problems may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
Raynaud's phenomenon: People with Raynaud's phenomenon experience poor blood circulation to the extremities. Brimonidine may make the symptoms of Raynaud's worse. If you have Raynaud's phenomenon, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
