Brief Answer: Must be a typo Detailed Answer: Hello Thanks for the query To the best of my knowledge there is no drug called rydroxyzin. It must be a typo. Please do check again with the prescribing doctor. I would like to add here that hydroxyzine is an antihistaminic drug most commonly used for hives, it does have a mild sedative effect but usually it is not given as a first line agent to induce sleep I hope I was of help, if you have any further queries please get back to me Regards

Brief Answer: Hello Detailed Answer: Thanks for the reply Sorry for the short delay in my reply, I was on call at my hospital I strongly recommend you to go back or at least call your doctor before taking these medications. Hydroxyzine comes in 50 mg strength and it should not be taken with xanax as it causes at additive effect of prolonged drowsiness. The main active ingredient is Hydroxyzine hydrochloride and inactive ingredients are anhydrous lactose, colloidal silicon dioxide, croscarmellose sodium, FD&C Yellow No. 6, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80 and titanium dioxide. At our hospital the management decided to give a printed prescription to everyone to avoid this confusion, maybe you could suggest the same to them to avoid such confusion. I hope I was of help Regards
