Roxyzin 10 Hydroxyzine Hydrochloride Pethidine
ModerateHydroxyzine may strengthen the effect of pethidine (meperidine) and barbiturates, so when used together before anaesthesia the doses should be adjusted for each patient.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
