What this interaction means in plain words
Methamphetamine and Serdexmethylphenidate / dexmethylphenidate can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
