Watch out for Interactions Between Drugs for Erectile Dysfunction and Other Medications
January 2009
The article lists 56 drugs that can interact with the three drugs for erectile dysfunction (ED): sildenafil (VIAGRA), tadalafil (CIALIS) and vardenafil (LEVITRA). Eight of the drugs are either nitrates such as nitroglycerin or a certain group of high blood pressure drugs.In combination with ED drugs, these drugs can cause a dangerous fall in blood pressure that could lead to a heart attack or stroke. Thirty-two other drugs can inhibit the enzyme that helps the body to eliminate the ED drugs, resulting in abnormally high blood levels of the drugs and a potentially harmful "overdose" even though you are actually taking the recommended amount. The other 16 drugs speed up the metabolism of the ED drugs, thereby lowering the blood levels and reducing the effectiveness of the ED drugs.
Dangers of Mixing Alcohol with Certain Medications or Diseases
August 2008
The article discusses 273 drugs that can have harmful interactions with alcohol. Also reviewed are several ways in which these harmful interactions can occur: 1/ Medications Can Increase Alcohol Blood Levels 2/ Additive effects of medications and alcohol. One of the best- known drug-alcohol interactions is when alcohol, a depressant, is taken with other sedative medications, and excessive sedation or depression of respiration can occur 3/Alcohol can increase the blood levels of some medications leading to toxicity of these drugs. 4/ Alcohol also can reduce blood levels of some medications causing them to be less effective. Although some of the interactions between alcohol and medications mainly occur in people who drink heavily (three or more drinks on one occasion), many of these interactions may occur with much lower amounts of alcohol use, such as one to two drinks on an occasion. We strongly urge you to tell your physicians and other health care providers how much alcohol you are drinking so they can effectively assess the risks and advise you about the safe use of alcohol and medications.
