If you develop sexual side effects while taking Atacand, be sure to talk with your healthcare provider. He or she may be able to diagnose the cause of your problem. There are also treatments, such as a medication for erectile dysfunction, that he or she can recommend that can oftentimes improve symptoms. If your symptoms continue or if your healthcare provider believes the medicine is causing your symptoms, he or she may recommend trying another medicine for your high blood pressure or congestive heart failure.
