The main problem with Cialis is hypotension, and arises mainly when taking the drug in conjunction with nitrates, which are mainly used by people with angina.
This doesnt arise with scuba diving anyway.
I have not considered effect of vasodilation, which Cialis would cause, on nitrogen loading into tissues etc.

Hi Capt Doug,
Viagra (sildenafil), Cialis (tadalafil) and Levitra (vardenafil) are used to treat erectile dysfunction. Known as PDE5 inhibitors, they work by increasing blood flow to certain areas of the penis.
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 chest pain due to coronary heart disease, is the 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, upset stomach and nasal congestion. 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 suggesting that PDE5 inhibitors theoretically could reduce the risk, but this work has a 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.
As a final note, be aware that Cialis has a much longer half-life than either Viagra or Levitra and with regular and continued use Cialis blood levels go on rising for about a week.
