Should I take my amlodipine for Raynaud’s year-round to treat glaucoma?
MAR 24, 2019
Question:
I have Raynaud's (when blood circulation to hands/feet is intermittently interrupted) and take amlodipine but only in the winter. Since Raynaud's and glaucoma are both caused by disorders of the capillaries, would taking the amlodipine year-round also help my glaucoma? Also, is there a higher risk of glaucoma for people who have Raynaud's?
Answer:
Raynaud’s syndrome affects one’s peripheral circulation and some think that this could affect the blood flow to your optic nerve. The subject of blood flow is an active area of investigation, but some studies suggest that Raynaud’s is associated with glaucoma, and in particular, with a type of glaucoma (called normal tension glaucoma) where the pressures remain in the normal range.
I would, however, be very cautious about using the amlodipine for your glaucoma. This too has been studied, and not only are there no clear benefits to using amlodipine, there are situations where lowering one’s blood pressure can limit the blood flow to the optic nerve and cause progressive glaucoma. Be sure to talk with your doctor before altering the prescribed usage of amlodipine or any other medication.
