A problem for many men, however, is that some types of blood pressure medicines can actually cause erectile dysfunction. That may make it difficult to stay on your medication, especially if your high blood pressure never caused any symptoms before.
Many drugs used to treat high blood pressure have been linked to erectile dysfunction. But some are much less likely than others to cause problems. Certain high blood pressure drugs may even improve erectile dysfunction for some men.
It's known that diuretics (or water pills, like hydrochlorothiazide) and beta-blockers (like Atenolol) can also cause erection problems. These are also the first drugs that a doctor is likely to prescribe if you are not able to lower your high blood pressure through diet and exercise.
