Is it ok to take lortab and promethazine while taking methadone?

It is generally not advisable to take Lortab (hydrocodone and acetaminophen) and promethazine while on methadone without consulting a healthcare professional. Both Lortab and methadone are opioids, and combining them can increase the risk of respiratory depression and other serious side effects. Promethazine, an antihistamine, can also enhance sedative effects. Always consult your doctor before mixing medications.
