if any of your medication is in tablet form, it might be possible to split it in halves or quarters with a pill splitter (ask your pharmacist to make sure this is safe for your specific pills. don’t try this with pills where getting an exact dosage is important)
if so, you can ask your doctor for a higher dose than you need, so that you can stockpile your medication for times when you don’t have access to healthcare
for example you could ask for double the dose that you actually need and then only take half a pill at a time. then just keep refilling your meds as if you’re taking them at the expected pace, and build up a stockpile over time
keep in mind that what I’m suggesting is potentially dangerous, but it’s also potentially dangerous to be deprived of medication for a prolonged period of time, so do with this what you will
another thing to keep in mind: this can sometimes backfire if it turns out that the higher-dose pills can’t be split, so it can be helpful to look up what the higher-dose pills come as (if they’re tablets vs. gel capsules, for example)
@kasdeya don't do this with anything that's supposed to be long-duration or extended-release, as those often rely on the outside surface being unbroken and you will get a very large dose of it immediately instead
