Direct consumer advertisement of drugs is also illegal in Germany. (I think there's only 3 or 4 countries on the planet where this isn't the case)
Also, they are allowed to advertise for things like cold medicine, when I still had a TV (log time ago, admittedly) I remember seeing lots and lots of such ads: "WICK MediNait cold medicinefor the night", list of ingredients: https://www.aponet.de/wissen/arzneimitteldatenbank/suchergeb... (active ingredients Paracetamol, doxylamine hydrogen succinate, ephedrine hemisulfate, Dextromethorphan hydrobromide-1-water)
Only for prescription drugs ("verschreibungspflichtig"), so no "ask your doctor if XYZ is right for you" bullshit.
Non-prescription drugs ("apothekenpflichtig") are heavily advertised in pharmacies, sometimes on billboards, and on TV. Most TV ads for drugs are running on ARD and ZDF [1] since that's what old people watch.
[1] Though only between 18:00 and 20:00, which is when the public broadcasters are allowed to air ads.
What is interesting is that if you really interesting is that a certain large pharmacy does a 200/12 ibuprofen + codeine combo.
I once had a prolapsed lower disc (from sport) and neck spasm (from stupidity) at the same time. Whilst I couldn't take naproxen (lots of reflux even with omeprazole), that and 500/15 cocodes with diazepam was the only way to get to sleep.
You're limited to 2 packs of 16 tablets each (for a total of 32 tablets) per transaction, in an effort to reduce the incidence of spontaneous suicide attempts.
