Certain anti-angina drugs, blood pressure medicines, grapefruit juice and the herbal supplement St. John's wort are among the substances that could negatively interact with popular erectile dysfunction (E.D.) drugs, the consumer group Public Citizen said Monday in releasing a list of 56 such substances.
The substances were analyzed when taken with the E.D. drugs Viagra, Cialis or Levitra, Public Citizen said in a news release. The substances are capable of causing either:
* A life-threatening drop in blood pressure,
* An overdose of the E.D. drugs because the other substances prevent the body from ridding itself of the E.D. drugs,
* Or reducing the effectiveness of the E.D. drugs by speeding up the body's metabolism.
Erectile Dysfunction drugs cause the blood vessels to dilate, and this process can be magnified when taken with blood pressure medicines such as Flomax or Cardura. Men who take hypertension medicines should avoid the E.D. drugs, the consumer group said.
The complete list of substances is available at Public Citizen's worstpills.org Web site.
