I carry what is necessary for the most threatening and most likely scenarios: Benadryl and epi-pens for anaphylaxis (My son has a prescription), ibuprofen for inflammation and fever, acetaminophen for fever and pain. I do have some Imodium, but I would hesitate to use it except to just get a person to a place where they can more practically deal with the problem. Imodium does not treat the disease, it only paralyzes the intestinal muscles to prevent evacuation of the bowels. It is best to get it all out and hydrate to actually get better. I guess it depends on how far you have to go to get to treatment. Rice and charcoal (hard wood and small amounts mixed in the rice) are good for getting the patient better if you can't get them out; it helps get rid of the cause, provides nutrition and slows down the bowel movements. When it comes to fever, unless it is higher than 102 (medical professionals weigh in on that number), I would not try to reduce it if you are in a remote location far from treatment, The fever will actually help to kill the infection and is not dangerous unless it gets too high. I know this thread was dealing with OTC meds, but I do carry Cipro as well. I carry it when I travel, and have it for camping and backpacking when I need it. it is good for intestinal infections (not parasites) and other infections. I would hesitate to use it on anyone else unless I felt the risks justified it though. If you have a cooperative doctor and can demonstrate that you are going on some sort of expedition, they can give you prescriptions for these things and instruction on their use.
