Ingredient by ingredient
Advil PM (Diphenhydramine) + MDMAUnsafe
Diphenhydramine stops you sweating, and overheating is the main way MDMA kills. Avoid this combination.
Diphenhydramine is a strong anticholinergic: it suppresses sweating and impairs the body's ability to shed heat. MDMA already raises body temperature and is most dangerous when someone cannot cool down. Blocking thermoregulation during MDMA use turns hyperthermia — the main way MDMA kills people — into a much more likely outcome.

Advil PM (Ibuprofen) + MDMACaution
MDMA already stresses the kidneys, and ibuprofen adds to that. Rehydrate instead of taking ibuprofen ahead of time.
MDMA can cause hyperthermia, dehydration and, rarely, rhabdomyolysis — all of which stress the kidneys. NSAIDs reduce renal blood flow, so ibuprofen taken to head off an MDMA comedown headache adds load exactly when the kidneys are least able to take it. Rehydrate rather than pre-dosing ibuprofen.
