Advil is the main brand name for this. I always buy a bottle and other pills when I’m in the US. It is way more than I need but what I like is all the US pills look different. I always have a little mixed bottle of Advil, Pepto Bismol (fixes everything stomach related), anti-histamine pills… with me for when I need them. You can mix them all together and still tell the difference between them. That’s what I don’t like about the European blister packs of unidentifable white pills. That and I hate blister packs. It is also cheaper to buy a bottle. But to be clear, I get like a bottle of 50 or 100. Advil is also enteric coated so it is better for your stomach and tastes better (it’s slightly sweet).
The typical dosage is 2 for all of them (excluding the rand german pill - the one that you have no idea what it is). It’s also ibuprofen, but you would never know it. Does that help at all with you being skeptical?
