    Viagra (sildenafil) doses must be low when the drug is used with HIV protease inhibitors (especially ritonavir), because these antiretrovirals reduce the metabolism of sildenafil in the liver, resulting in abnormally high blood levels which can cause adverse effects. The combination does not seem to affect blood levels of protease inhibitors. Sildenafil, used to treat erectile dysfunction, is supplied as tablets in three doses: 25, 50, and 100 mg, and is taken 1/2 an hour to 4 hours before intercourse. Doctors often start with 50 mg, then lower or raise the dose if needed. According to an April 21 "Backgrounder for HIV Treatment Advocates" from Pfizer Inc., "Given the magnitude of the interaction between sildenafil and protease inhibitors, ongoing discussions with the FDA indicate that a maximum single dose of 25 mg of sildenafil in a 48 hour period should not be exceeded in patients receiving these agents concurrently." There are other medications which require caution if used with sildenafil (and some which must not be combined at all). Patients should obtain this information from a medical professional, or from a recent copy of the official labeling of the drug. [Note: The current labeling, dated February 1999, is considerable less cautious than the Pfizer backgrounder quoted above. Consequently each individual patient should be assessed by a doctor before a decision is made to prescribe Viagra. The doctor will take into account current and past medical history including any medications being taken. Here we will take a look at the factors which may render Viagra unsuitable. The level at which you drink alcohol and whether or not you use recreational drugs can impede on your ability to obtain an erection. In order to minimise the potential health risks associated with alcohol consumption, the NHS advises that adults should not drink more than 14 units over the course of one week. It is also pertinent to mention that sustained alcohol misuse can permanently damage the arteries that supply blood to the penis. Drinking alcohol or taking drugs when using Viagra can reduce its efficacy.
