Xavier, what is the exact name and strength of the generic you are speaking about. I would like to try it.
Would you know any specific pharmacies in SD or Sousa that sell it.
There is a generic brand of Viagra that is sold in the DR. The box has a white horse with wings with the name sildenafil citrate. I forgot the name and I do not have the box, so I can't take a photo of it for you. But it works just like the Pfizer.
Then there is this one, made by a reputable Latin American pharmacy-
The price for this pill may be higher in Sosua, for obvious reasons-exploitation of the monger market. There are pharmacies along and around the side streets of Avenida Independencia in Santo Domingo (close to Clinica Abreu near El Conde) you can check out.
I highly doubt you will go wrong if you follow these instructions. The prices will be around the US $2.00/per pill ballpark. You will not have to worry about the efficacy and quality. Don't think quality is affected by the low price.
I use medication from the DR that are made by laboratories in Latin America and India with no problems. One is an injectable cortico anti-inflammatory that is so cost effective it's ridiculous-a year's supply costs me what a two week dosage would if I purchased it here in the states.
Just don't ask anyone to procure the generic Viagra for you, either Dominican or expat. This is where you will wind up in trouble. Go to the pharmacies yourself and ask to see the boxes, even if you only want to purchase one pill at a time. Reason is you will be able to see where they are taking the pill from, and sometimes there is a price tag on the box so they won't be able to gank you.
Hope this helps.
