What is Zyrtec?

Cetirizine (trade names Zyrtec, Reactine) is a second-generation antihistamine used in the treatment of hay fever, allergies, angioedema, and urticaria. It is a major metabolite of hydroxyzine, and a racemic selective H1 receptor antagonist.

Second-generation antihistamines like cetirizine are less able to cross the blood-brain barrier and therefore have diminished effects on the central nervous system compared to first-generation drugs: for instance they are less likely to induce drowsiness or to interfere with memory formation.

Right before xmas i was diagnosed with bronchitis . I was put on augmentin 875mg/bid, proventil, mucinex d , and my normal flonase and zyrtec. I completed the meds and wound up starting to get sick again last wednesday. Started with a cough, non productive with post nasal drip . Went to dr on thursday to nip it in the bud. She increased my flonase to bid, zyrtec in the morning, benedryl at night, tons of fluids, and tessalon perles to help the cough. I began running a fever that night of 100.8, which beleive it or not, has never gotten that high in my life.. the cough got worse, followed by body aches, labored breathing , fever was consistant even using 800mg of ibuprofen or tylenol.this last until monday and i called the dr again. She called in zpak and 40mg a day of prednisone. My fever finally broke that night, but i also was having green diarrhea. It is my 2nd day on prednisone and zpak, feel better than i did, but my fever is creeping back up to sinuses are still stuffy but i can blow my nose, still have a non productive cough and i cant walk up the stairs without having to take a break to catch my breath. I am also still ahving green stool.. HELP! Any ideas on what is going on...

My 49 year old wife has a small (approx. 1/4") sore reddish brown sore rash (No Lumps) on her chest just below her collar bone. She has had this for 2-3 days and there is only one spot. She currently has sinus congestion. She says the small rash is sore/ichy.
Thanks for the query

It looks like your wife is suffering from an allergic reaction. Since there are no other rashes anywhere else, it is most probably a focal dermatitis.

What you can do is apply calamine lotion which is easily available in stores on the rash, this will take care of the...

About six days ago I noticed several mosquito bite-like welts on my hand . They became more pronounced the next day and extremely itchy. I put aloe vera gel on them regularly and the itching subsided a little. They went from mosquito bite-like welts to smaller red dots. However, on the third day, I started to get a couple more itchy spots on my right arm , but no where else on my body. Then on the fourth day I got a bunch of itchy spots on my right arm, just a couple on my left arm, and over both of my shoulders. My left arm is better now, but my right arm looks as if it was bitten about 30 times. However, they are definitely not mosquito bites. There is no pus or fluid inside, they are just raised welts. During this time, I have had no fever, tiredness, stomach pain, or any other symptoms. It is purely a skin itch and rash. I have checked online in many places. I am pretty certain it is not scabies or chicken pox . It could possibly be a mild case of shingles though. I have never had chicken pox or any other skin disease. I can send pictures if that would help. I am an otherwise very health 26 year-old weight 160 pounds. Thanks for your input!

Hi. I have a tooth abscess that my dentist prescribed an azythromycin z-pak for. I forgot to tell him that I took a Zyrtec-D pill this morning around 6:00. I also started an herbal dietary/weight loss plan this week. I took a dose of Phenocal at 8:00 this morning and again at noon. It has lots of vitamin B's in it plus some green tea leaf among some other herbal things. I am wondering if I am OK to go ahead and take the azythromycin or if I should wait until morning when the other two things are out of my system (or are they already)? Thanks for your help!
hi, .thanks for your query azithromycin does not interfere with any vitamin supplements or green tea.there are also no known drug interactions with zyrtec-d pill.but with phenocal please take your physician advice as the weight loss pills will also have many other can take the...
