Vitamin V: Yes, Viagra is readily available at any pharmacy/drug store in Rio. You should be able to buy it without a prescription. Enter any drogaria and go to the pharmacy counter-often at the rear-and ask for Viagra or, better yet, if you don't speak Portuguese, hand them a piece of paper with the word Viagra written on it, along with how many you want. Viagra is generally sold in boxes of 4-50 mg. doses. A box of four should cost about 62 reais.

Condoms: I and many other men find the Brazilian condoms to be tight, thick, and a bit unreliable (I've blown a few), so I always bring my own, even to the termas. These days there's a chance that your stash of condoms will be inspected by security personnel at an airport, but so what! I just smile and say "I'm going to Rio on vacation." And, no, your condoms will not be confiscated by the customs folks in Rio. They've seen it all. You may also want to bring along a good lubricant for those garotas who insist that you give it to them up the ass. I prefer water-based lubricants like Wet Platinum. You needn't bring this to the termas.
