Overheard this conversation between a patient and one of my coworkers today: Patient: "Do you have Allegra-D?" Coworker: "Yeah." Patient: "Okay, I don't want that." He eventually ended up getting Claritin-D instead, but... I still can't comprehend what was going through his mind during that bit of c
In the spirit of curiosity and want to see a little bit more "fun" content" in this subreddit, I want to ask you other fine reddit pharmacists about what personal items you take into every shift you work. In my own experience, there is a list of creature comfort items (not available in the realm of
There’s some features that we use frequently that make our jobs easier and more convenient. As with all software, there are annoying issues and bugs, and relevant information is sometimesinconvenient to access or even absent. What are your favorite features and greatest frustrations with your pharma
On the medscape drug interaction checker, it says that loratadine will increase the level or effect of amitriptyline by P-glycoprotein (MDR1) efflux transporter. Use Caution/Monitor. But when I checked cetirizine & fexofenadine, they had no interaction with amitriptyline. Why is this the case?
I’ve seen some studies possibly linking antihistamines with dementia. Does this include Fexofenadine despite it not passing blood brain barrier and having little impact on ACh?

Hello! I’m a 4th year pharmacy student from Finland and recently I’ve become curious about what pharmacy is like in other countries as a study subject and what is it like to work. I’d like to share some details what pharmacy is in Finland and maybe hear some of your stories from your home countries
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
So 25 year old Orla Baxendale died after eating a cookie that had peanuts despite treatment with an EpiPen. Beta adrenergic activity includes suppressing histamine release but of course doesn't act directly against histamine. My thinking is that the market should include a combination product tha
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
