Is it possible for you to order rectal meds from Canada? I know a lot of US citizens on here order meds from Canada. Your doctor would have to write a prescript
ion, but if you have that, do you think it might work?
Editing to add:
Ok, so I'm a (bored) dork, and decided to see if I could figure out if a Canadian pharmacy would ship to Guatemala. I was looking around on one site, and couldn't find any info, but they did have a live chat customer support, and the guy I chatted with said that they will ship mesalamine enemas to Guatemala. It may be a hassle, but you might want to look into it!
