Avatar f tn The half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. Hope that helps.
6298176 tn?1380134459 It has a very long half life, though I can't give you specifics. The dose and how long you were on it does factor in. Your doctor should be able to help you with your questions on this.
Avatar f tn Amazingly enough, I am able to go several days without any itching! I took half a Zyrtec the first night of the fast. By day 4 I ended up taking another half b/c the itching became unbearable. I haven't taken another one and tonight the itching is starting to get worse, but it's not too terrible yet so I'm going to try to tough it out. Someone in a previous post mentioned it taking 2 weeks to recover, so hopefully I can last that long.
Avatar f tn It only is in the system for a short time based on its half life. Children can take this usually without incident. However, once stopped, some allergy sufferers are uncomfortable. Perhaps this is what is going on. Again, please talk to his doctor. Why did you discontinue it? Was there a particular reason? It's an antihistamine. Sometimes weaning down on the dose can help with that occurrence of increased allergy symptoms upon discontinuation.
Avatar f tn Nothing works for me, but Benadryl. My doctor said Claritan and Zyrtec are safe, they just don't work for me. I started taking either half of a regular Benadryl during the day (so I won't get sleepy, haha) or children's Benadryl (it's about the same as half of a regular one). That seems to make my allergies tolerable throughout the day.
Avatar f tn he has a dermatology appointment on Thursday I don’t want to put him back on prednisone again he’s gaining weight the Zyrtec does nothing and he has not been on any antibiotics. Some of the spots are half circles with white in the middle which looks like ringworm but his allergist said it’s not. I don’t understand why he has not been on an antibiotic I don’t think my son is pushing hard enough.

535882 tn?1396576685 whats the half life for syntriod. about how much time does it take to build up in you and also leave your system?
Avatar f tn t seem to be doing the job. I am a stuffy, sneezey mess with watery eyes half the time. And I need to function so Benadryl is not an option unless I am able to sleep all day.
Avatar m tn Alright thanks,and no i take plain zyrtec,not zyrtec d,it doesnt contain pseudoephedrine....i called up my psychiatrist,he said its nothing to worry about,its common with all the medicines im taking,im meeting my physician later this week,and he can then recommend a cardiologist for me....
Avatar f tn I have seasonal allergies and was wondering the best OTC antihistamine would work better. Allegra, Zyrtec or loratadine. I was on 12.5 zoloft for 2 weeks and tapering up to 25 mg (split another 12.5 in half so 3/4 a pill then one whole 25 mg. I have to do this slowly as I am super sensitive to meds. Thanks for any help. Plus I eventually need to taper down my ativan when I level on the zoloft.
Avatar f tn Has anyone experienced severe itching problems when they stop taking Zyrtec?
Avatar n tn If your son is prescribed 5 mg of Singulair then try to get that instead of a 10 mg preparation (you can get 4 mg and 5mg chewable tablets—ask the pharmacist or the doctor about these). Usually a medication which can be broken into half and used this way to half the dose has a line break on the tablet. Usually Singulair does not have such line breaks. Instead, ask your son’s doctor whether you can use Singulair 4mg granules. Do discuss this dosing with your son’s doctor. Take care!
Avatar f tn Ask your doctor for zyrtec or zofran both are life savors.. Youll wonder why you didn't ask for them in the first place.. There what saved half of us pregnant mommies so far lol.. Im 34w2d & ive been on zyrtec since 6weeks!
Avatar f tn Mine said benadryl.. & I weigh 109 so she said only take half & try not to take one everyday.
Avatar f tn Had been on Augmentin for a sinus infection, just finishing up the script, and take Crestor, Nexium, and Zyrtec on a regular basis. Symptoms started a few days after starting generic Zyrtec, which also caused unbelievable dryness that felt like I was dehydrated (no vomiting, though). A day after the chills, I noticed my urine was dark and my stools were very light, almost gray, and I started getting very itchy but no rash.
312330 tn?1245176752 I think 5 is still pretty late since the half life can last a while. You may also want to reduce the dose of your last pill.
1084115 tn?1385228589 The mean half-life for multiple doses in the body is about 12 days, but very long-term kinetics are dominated by the kinetics of RBCs (half-life 40 days). RBCs store ribavirin for the lifetime of the cells, releasing it into the body's systems when old cells are degraded in the spleen.
459155 tn?1264008142 ok plz if I am explaining this wrong (anyone feel free to correct me if I am ) The 36 hour half life mean half of the dosage is still active at 36 hours ??
738895 tn?1234654277 I think heroin has a half life of 4-8 hrs, and methadown 20-36hrs, i understand that it takes 36hrs for half the drug dose to leave your body, but theres only 2 day deference between the two drugs but methadown takes months to kick and heroin weeks. thats the part i dont understand but theres only 2 day deference between the two. anyone with knowledge please try in a laymen terms to explain. thanks for any help in advance.
