Is nitro, either in patch form or cream, something you can buy OTC or do you have to have a prescription?
The nitro is a cream in a tube and I'm betting you have to have a script.
It's a prescription. Ointment, patch or sublingual pill. I would think a patch would be difficult to put on a hairy animal plus you have to activate it with pressure and you would have to get the pill under their tongue and let it melt:') By pick up I meant the next time I'm in Mexico I'm going to see if it's legal to bring it across as a vet med.
