Diving
on Popular Medications Viagra, Cialis and Levitra are used to treat erectile dysfunction. Known as PDE5 inhibitors, they work by increasing blood flow to certain areas of the penis. They are prescription drugs. Like all medications, they have side effects. Most worrisome is a potentially dangerous decrease in blood pressure in those taking certain other drugs which also dilate blood vessels. Nitroglycerin, a drug sometimes prescribed for angina pectoris (chest pain due to coronary heart disease), is a principal example. Aside from this, possible side effects tend to be transient and only mild to moderate in nature, but still can be problematic for the diver. In order of reported frequency, these include headache, dyspepsia and nasal congestion or rhinitis. Cialis also may cause muscle aches and sore back. Taking one of these medications in proximity to diving could impede equalization of the ears and sinuses; cause the discomfort of headache and sore muscles; and result in heartburn, bloating, nausea and burping, complaints that could be further exacerbated by the prone and sometimes head down positions assumed while diving. The well-known "blue vision" that is a potential side effect of Viagra generally seems of little concern to diver safety, although those with retinal disease will want to consult with their ophthalmologist before starting the drug. There is no reason to suspect that these medications increase the likelihood of DCI. There is preliminary research with animals suggesting that PDE5 inhibitors theoretically could reduce the risk, but this work has a very long way to go. The diver taking one of these drugs will want to monitor for topside adverse reactions before diving. Among other advantages, this may prevent symptoms like headache and muscle ache from being confused with DCI or vice-versa. As with any medication, understand all information regarding side effects, precautions, drug interactions and other warnings. Any limitations or risks imposed by the condition(s) causing the erectile dysfunction, e.g., diabetes, obesity, psychiatric disorder, also must be considered.
