Hi. Thanks for your question.
I am a board certified neurologist in the U.S. I will be happy to help.
There is no absolute contraindication that I am aware of to take Viagra or similar type of medications in the presence of a brain aneurysm. I reviewed a reliable source and found multiple contraindications which include a stroke within prior 6 months, but no mention of aneurysm being a contraindication.The main concern with viagra in a patient with an aneurysm might be elevated blood pressure causing a rupture of an aneurysm or an aneurysm rupturing due to the blood vessel dilation that viagra can cause, so theoretically there might be some increased risk over a patient who does not have an aneurysm.
It should also be considered that sexual activity by itself clearly can raise blood pressure and thereby in and of itself can be considered to have some risk in a patient with an aneurysm, therefore if a rupture of an aneurysm occurs with sexual activity in a patient on viagra, that could be due to the sex rather than the medication anyways.
My suggestion to you would be to discuss this issue with the treating neurosurgeon or neurologist who has further details in terms of the location and size of the aneurysm, and to ask him or her about the risk not only of viagra or similar medication but also about the risk of sexual activity and whether this would be safe given the particular details of the aneurysm.Hopefully this provides some guidance to you. Best wishes.
Thanks for you reply; much appreciated.
I do not have a confirmed aneurysm at this point, just a strong predisposition. I was advised against having a scan at this time. Therefore I am not currently under the care of a neurologist. I have been told by the neurologist I saw previously to try and live a normal life and not eschew things like high intensity exercise.
My worry, which you touched upon, is the blood vessel dilation caused by such medications. I cannot find anything about not using them in such cases but logically it seems that I should not.
You say it is a "main concern" but that there is no contraindications with these meds. In your professional opinion is it enough of a concern to prevent there use? Would some sort of localised injection be preferable?
