Hydroxyzine Overview

Hydroxyzine (/hadrkszin/; sold as Vistaril, Atarax) is a first-generation antihistamine of the diphenylmethane and piperazine class. It was first synthesized by Union Chimique Belge in 1956 and was marketed by Pfizer in the United States later the same year,[2] and is still in widespread use today. Due to its antagonistic effects on several receptor systems in the brain, hydroxyzine is claimed to have strong anxiolytic and mild antiobsessive as well as antipsychotic properties.[3] Today it is...

Is it safe to take bupropion SR and hydroxizine pamoate at the same time for anxiety and depression? ## Hello, Sherry! How are you? I didn't find any problems or interactions listed between these two medications, but it's always best to double check such information to be safe. As listed by the FDA, Bupropion may cause side effects, such as nausea, dizziness, dry mouth and drowsiness. Hydroxyzine may cause side effects including dizziness, drowsiness, sedation and dry mouth. Is there anything else I can help with?

Small round white pill size of an eraser with301 on top H under it and blank on other side ## Hi val, Based on your description and me not finding anything on H 301, I decided to look up similar imprints and came across a white round pill with a marking of "H" over "106" on one side and blank on the other. Get this though - if you turn it upside down it reads "301" on top and "H" on the bottom, (depending on how faded the number 6 is). At any rate, this particular pill is identified as a 25mg Hydroxyzine hydrochloride tablet, used for a anxiety, allergies, nausea, as well as a number of other indications. Any thoughts on whether this might be your pill?

Is it safe to take a prescription dated 8/2013? ## Hello, Dolly! How are you? It doesn't get dangerous once it's expired, but it does begin to lose effectiveness, so it may not work as well as it did, when it was new. Medications tend to degrade over time. Thus, it would be best to dispose of it and see your doctor for a new prescription, if you still need to take it. The FDA lists the typical side effects of this antihistamine as possibly including nausea, dizziness, drowsiness, dry mouth and somnolence. Is there anything else I can help with?

why doesn't my hydroxyzine hcl 25 mg tablet work at night

my hydroxyzine hcl 25 mg tablet works to controlling my itching during the day, but when I go to bed I still itch, I have even tried doubling the dose ## Hi Pat, What time do you usually take your evening/nighttime dose of hydroxyzine? Part of me wonders whether it has enough time to digest if you're going to bed directly after you take it. Based on several reviews I've seen online, hydroxyzine should "kick in" sometime within 30 minutes to an hour an a half after you take it (w/ effects lasting for hours). However, one other thing to think about if you're only itching at night, is if you might be allergic to the type of bedding you have or perhaps a new laundry detergent? I've heard about that happening to others as well so it seems to me like it may be a prime ...

Yes, that is one of the side effects listed for antihistamine by the FDA, along with dizziness, drowsiness and dry mouth. It usually doesn't happen with short-term use, but long-term regular use could cause it. Usually it's a gain of 10 pounds or less. Are you on any other medications?

used for allergies and anxiety ## Hello, D Jane! How are you? There are quite a few other antihistamines available, some via prescription and some over the counter. But many don't help as much for anxiety, but one over the counter option would be Diphenhydramine and another prescription option would be Promethazine. The FDA lists the typical side effects as possibly including dizziness, drowsiness, dry mouth and weight changes. Is there anything else I can help with?
