Survival Medications
In a survival SHTF situation food and water may only be available from questionable sources.
Diarrhea and nausea can kill in short order, and least weaken you when you can not afford it.
I pack over the counter meds such as Benadryl for allergies, Dramamine for nausea, Immodium AD for Diarrhea, Tylenol for pain. I also add Triple antibiotic ointment and bandaids. A pack of Quickclot finishes it out. Don't forget your prescription medication and keep a copy of the prescription with them for the police should you be stopped and searched.
