Related to all these GLP-1 meds, I saw an alert from the UK: anyone on semaglutide needs to watch for vision changes and get to the ER ASAP if they notice anything. It's a really rare risk of something called NAION.
it's a regulated compound. the manufacturer studied it being kept at room temp and used daily for 28 days and it held up fine. that's the only guidance they can legally give without claiming more than what the study showed. people get tripped up thinking day 29 is when it goes bad.
To add to what Nat67 suggested, it's also worth keeping a headache diary. Note down when they happen, how severe they are, what you ate, and any other meds you're taking. This can help your doctor identify potential triggers.
