Mephedrone is more toxic than acetylsalicylic acid, ibuprofen, naproxen sodium, docusonate sodium, sodium bicarbonate, sennosides, diphenhydramine, and dextromethorphan but less toxic than isotretoin, haloperidol, quietiapine, olanzapine, sumatriptan, prednisone, seconal, alpha-methylsufentanil, oxycodone, and thalidomide.
The most common side effect is a reversible headache and occurs half of all users of the drug. Its most serious cosmetic side effect is vasocontriction of the blood vessels of the body's extremities causing them to turn blue temporarily; this side effect occurs in about 15% of users. Idiosyncratic sudden death of the mdma type occurs at about the same rate as seen with that drug (approximately 1 death per several million usages or so).
