Blood Pressure Home > Dynacirc CR and Impotence
In studies where men took Dynacirc CR (isradipine CR), impotence was reported as a rare but possible side effect. Since impotence occurred in less than 1 percent of men taking the drug, however, it is difficult to determine whether it was caused by Dynacirc CR or other factors. If you are taking Dynacirc CR and impotence occurs, talk to your healthcare provider about treatment options.
Dynacirc CR® (isradipine CR) is a prescription medication known as a calcium channel blocker. It is used to treat high blood pressure (hypertension). As with most medicines, side effects can occur, and impotence may be one of them. In studies, impotence was reported in less than 1 percent of men taking the drug.
Impotence is usually defined as a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Ultimately, impotence is the repeated inability to get or keep an erection that is firm enough for sexual intercourse. Impotence is also known as erectile dysfunction (or ED for short).
It is impossible for your healthcare provider to know whether you will develop impotence while taking Dynacirc CR. It may also be difficult to tell whether impotence is caused by the medication itself or other problems.
If you are taking Dynacirc CR and impotence becomes a problem, make sure to talk with your healthcare provider. He or she may be able to recommend treatment options. Depending on how severe your symptoms are, your healthcare provider may also recommend that you take an erectile dysfunction medicine, adjust your Dynacirc CR dosage, or try another blood pressure medication.
