YES IT DOES CAUSE DEPRESSION, that is the reason i ended up on the internet late night trying to see why i feel like my whole life is ending when i have nothing in my life to be sad, or upset about at the moment. Everything is great with me.
Im nearly working my way into Medical school at USC and things like this, is what drives me.
Now that i know this is a FALSE temporary sense of Depression it seems that helped with my mood almost instantly. It can be a mind thing.
Everyone experiencing this should remind yourself that this is a False sense of depression from this medication and that everything is gonna be alright.
Just Pray, and say to yourself "By his stripes I am healed". The devil is a LIAR !!!
So sorry about your loss.
I have no scientific proof other than my own experience but I believe it does. I take Claritin and have been feeling depressed/down. I stopped taking it for a couple of days because i couldn't afford to purchase any until pay day. I didn't make the connection until I started taking it again after not taking it for 6 days. It hit me on day 2 that I was going "down" again so I stopped and having been feeling much better emotionally. I suggest speaking with your local pharmacist and see what he/she has to say. Take care!
I knew something OTC eventually was causing my depression, lethargy. First, it was Unisom Sleep Aide a powerful anti-histamine. I quit taking due to developing a resistance and my depression lifted. Then got nailed with seasonal allergies and started 24hour Alegra. The result was severe depression, lethargy and so suicidal I had a plan to end my life. I already am on an effective antidepressant but "suddenly" did not work? The entire change in my behavior, mental deterioration, etc were caused by antihistamines. Unfortunately, the clinical trials are short on Alegra and these kind of sxs do not show up in Manufacturer's Information or a PDR. What meds have I not reached out to the internet forums/message boards, or available a post study for help? Clinical trials of any med are short and hopefully find post studies or as this a forum. Doctors do not think out of the box.
I have gone on this med this year for allergies and last year as well, and I believe it absolutely causes negative mood changes, nightmares, etc. I am a clinical psychologist and pretty self aware and 48 hrs. after stopping feel noticeable better (even with my allergy symptoms). Now trying butterbur for allergies because sick of the side effects of these kinds of meds.
I am so sorry for your loss. I have no doubt that Allegra could have been what caused your daughter's depression. I am so so sorry. My heart aches for you and your family.
