Hi! I'm an active young guy with mild hypertension, in which I'm currently taking Irbesartan every morning and is now controlled well. I enjoy traveling in hot conditions, some days can be up to 39 degrees. Can my blood pressure medication stand such heat if I was to say just put it in my wallet? I'm always traveling to different places and don't always have access to a fridge or ice to take on hand. If not, are there any other heat resistance BP medication i can try?
