Hi guys, I 40 M wanted to share a life changing experience. I drank way too much beer almost every day over the summer. And before that too, but the summer was brutal. However, I've been sober since the beginning of November. The first 10 days were not fun. After two weeks it got a lot better. I suf
All generic Xyzal is on backorder through our wholesaler and we were completely out today. A patient arrived to pick up their prescriptions—one of which was Xyzal #30. We of course weren't able to fill it so I left the counter to grab some OTC brand-name Xyzal after the patient said that they were f
for some of us, LC is going to be a lifelong condition. i've seen lots of posts recently from folks for whom this realization (or at least deduction) fills them with despair. i understand 100%. i am likely in that same boat - i.e., i'll almost certain never be cured, and the rest of my life will req

My hospitals latest initiative is to increase patient satisfaction scores which is fine and dandy but as pharmacists, I don’t think patient satisfaction is our role. We are now spending close to half of our day doing admission interviews on all of our new inpatients to inform them of all the new med

Does someone here have a copy of the Phase 3 clinical trials that were used to get loratadine approved in the USA? Willing to share? I've been looking around and I can't seem to find the studies. As far as I can tell, the efficacy is in the mid 40 percents for loratadine, mid 30 percents for placeb
I don't remember where I first learned it, but for the past several years I had it in my mind that diphenhydramine is more effective and quicker than cetirizine, loratadine, and the other second (or third) generation antihistamines at relieving itch and rash symptoms. Every pharmacist I've spoken to
(4 mg) What do we think about this? Be it preventative, relief or both. Here in Australia we have the brand "Periactin" and it is Sched 3 (behind the counter but without script) and comes in a 100 qty box, usually sitting with the other old fashioned / sedative systemic antihistamines, like Prometha
