I think I’ve mentioned this before, but clonidine is available in a transdermal patch- same concept as a nicotine patch. It’s not really conventionally used BP medication for general hypertension these days, but if your BP is super high it is an option. It’s an alpha-2 agonist which primarily reduces BP by relaxing blood vessels and to some extent reducing heart rate.
Clonidine as an alpha-2 agonist can also reduce gastric secretions (stomach acid production) which may be benefitical considering your situation.
