Good evening,
For common medications like antibiotics or paracetamol, you never need anything.
The country used to have a reputation for being very strict about psychotropics, anxiolytics, and the like, but I think that’s a thing of the past.
The go-to source is Caravanistan’s website—it’s a travel agency, sure, but also a really solid source of information.
On this topic, they’ve updated their advice in recent years, and their page is super helpful:

I recently read about someone who was held up at customs for a long time because of their meds. It’s best to play it safe: make sure the prescription lists the active ingredient, not the brand name, and keep the original packaging. Customs checks can be unpredictable, often random. Safe travels! Martine.
