Zyrtec half life

Common Questions and Answers about Zyrtec half life


Avatar f tn 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. It's very interesting that someone else mentioned the gluten issue, as well. I went on a gluten-free diet for 1.
Avatar n tn I have been on claritin, clarinex, zyrtec and xyzal. I am continuing with zyrtec now becaue of the cost of xyzal ($200/3mo) due to my healthcare selectively removing antihistamines from the formulary. Xyzal was definitely better for me than any of the others, and I have something more than the standard statement to go with that. Last week I had an allergy test done. RAST/Interdermal type.
Avatar f tn Actually Penicillin has a very short half life in our body, as it gets metabolized very fast. That is why frequent dosing schedule is followed. Your reaction started 2 days after stopping the drug and continues even 6 weeks after stopping it. In my opinion this is not due to Penicillin. You must undergo both skin and blood tests to determine what the allergy is due to. The chances that it is due to Penicillin are very slim, according to me.
Avatar n tn 2-3 years and have always taken different antihistamines (Zyrtec, Claratine, Allegra). I have found out that I am 6 weeks pregnant and have been advise to stop taking these meds (I'm currently living in Australia). I have been told that I can take Polaramine but should only take it when really necessary "when the benefits outweigh the risks". Obviously, this is not a life threatening condition but it is EXTREMELY uncomfortable.
312330 tn?1245180352 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.
Avatar m tn I don't think there is any direct health risk (heart attack for example) for skipping 2-3 doses. Zyprexa have a relatively long half-life that can be more than 48 hour. The side-effects you can get from skipping doses are more neurobiological, excess dopamine for example that could produce schizophrenia symptoms, psychosis if you are treated for schizophrenia or had psychotic episodes before.
Avatar n tn ) I also went back to the allergist for my 2mos fu and everything looked like before the allergies, the pft's were improved, and I left with a script for a half dose daily of Zyrtec-which they insist does not raise BP, but I had normal bp for three years on Hyzaar, normal bp week before Zyrtec started, and today I had my gyn checkup (3yrs) and bp is still higher than before Zyrtec. But Zyrtec is a miracle so as long as no headaches I will keep with it.
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 m tn My problem is this mucus I get around the clock in the back of my throat. It feel like it's half way choking you and it really drives me nuts! I take mucinex, nasacourt, zyrtec and it helps sometimes but not always. I can live with the change in diet but this mucus choking feeling is really affecting me as far as working out, karate, work and coaching football. When this mucus gets in my throat I do not want to do anything.
Avatar n tn In 2nd grade I started to ride the bus and I had to walk a half a mile to get home cause i live out in the country. Well, one day when i got home i had bumps or hives all over my arms. We went to an allergie specialist about 3 years ago and he called it U.V. Hives. He also said there was no cure, I can either take shots for 5 years 3 times a week, or I can take Allegra the rest of my life. I've been taking Allegra and it doesn't seem to help a lot.
Avatar m tn He is left feeling weak and nauseous for most of the morning. This has been going on for over 2 years and has cost him a normal life. He can't work a regular job, is very depressed, can't even eat breakfast. We don't have insurance, so the only treatment he has had is some antibiotics which seemed to help short term, and allergy scripts (now he just takes zyrtec every day which seems to keep the episodes down to the 20 minutes).
Avatar n tn Benadryl doesn't really work for me anymore and claritin and zyrtec are effective for only half the day. I took 2 tablets one day (about 4 hrs apart) and became very drowsy and felt like I was in a fog the whole day. My nose had a bad reaction to the nasal spray the one time I tried it - it became very congested and I was sneezing for an hour.
Avatar n tn I tried claritin and benadryl for rash with poor results. I was prescribed zyrtec 2 days ago, and have greatly improved from it. Questions: Have you seen a rash develop from lamictal after somkeone has been on it for so long without any problem? Could the reaction I am having now be because my immune system has been compromised from MRSA/stress? And/or now am more reactive to the lamictal? I do not want to go off the lamictal, as it has been like a miracle drug for me.
Avatar m tn I had protected sex about two and a half months back, I'm having on and off symptoms. 1. Low grade fever (Food poisoning) Happens once. 2. Rash, Looks like Hives (I've never had Hives before) 3. Diarrhea, happens after I took medication? (Amoxicillin) 4. Inflame Tonsils (Mild pain, no coughing) These symptoms doesn't come all at once. The rash happens out of nowhere and it's freaking me out, I took zyrtec and it took care of it.
Avatar f tn You don't specify the medication. The term "allergy pill" is insufficient. That being said it is probably safe for one time if this is an over-the-counter medication. It would not be unreasonable to suggest a visit to the ER if this happens again. Cutting to the chase, you require a professional evaluation by a physician specializing in allergies. In addition you need a prescription for "emergency" medications.
Avatar n tn my 5 year old daughter has had a chronic cough,or what seems like what i would call a half cough for about two months now. it continues all day until she goes to bed at night. then when she goes to sleep she doesn't cough? we just went yesterday for allergy tests and she had a strong reaction to cats. so we are going to have to get rid of our cat no question when it comes to my childs health, even though we love the cat, our daughter comes first.
Avatar n tn I can't sleep at night (about 2-3 hours an night), and sleep with ice packs on my back and neck. Needless to say, what a love life!! :) There are no triggers for the hives either. They are there all the time & it is not detergents or food either. Anyone have any ideas??? I will take any advice or anything. I am at my wits end. I cry all the time. Thanks for your help!
138239 tn?1239928524 Nasal sprays like Flonase really do work, especially when taken with Zyrtec. Personally, I take Zyrtec-D instead and prefer it. I also gargle with Listerine because I can get throat infections too. I never drive with my windows down because I can get an ear infection too! When I go on roller coasters or on a boat, I put cotton balls in my ear to stop allergens from entering in that way. I run a dehumidifier in my classroom and 2 air purifiers in my home.
Avatar m tn She uses Albuterol, budesonide(oral inhalers) in her nebulizer and some antiboitics(if she has fever), she takes Nasonex shots, and she uses Waldryl allergy and Zyrtec. I discussed the situation with my pediatrician and because of the blood contamination incident, we got her tested for Hep A, Hep B, Hep C and HIV after 5 months 20 days after the incident. Now she is 4 years old.
Avatar n tn The rash is a cluster of red bumps and most concentrations of them are about 3-5 inches in diameter. The rash itches all over very intensely when I drink alcohol. After half a beer it starts and it is unbearable. This rash is very unsightly and I feel like a freak. I am single and I am never going to find a woman with this ailment. This started 2 months ago and has gotten progressively worse. QUESTIONS: What is causing this?
Avatar m tn If it's caused by allergies, what kind of antihistamine would you recommend? I tried Zyrtec for about a week and stopped using it because it also didn't have any immediate effect. Does it take longer than a week to start working? I don't know what else to do and this is driving me insane. The doctor said my other option is surgery but I want this to be the last resort... Anything else I should consider in case this is allergy related?
Avatar f tn chronic daily headaches started. -Mar 2014- I started on a nightly dose of Flonase and Zyrtec Mar 2014: headaches stop -Aug 7, 2014: stopped taking Nexium, one week later the headaches come back even though I'm still taking the allergy meds. -Sep 2014: started nexium again but headaches still persist. -Oct 2014: stopping taking allergy and nexium meds.
Avatar f tn He tested for a large variety of autoimmune disorders. The doctor is treating my symptoms with Zantac, Zyrtec, and Singulair. I still wake up to hives every morning. And do not get any new ones during the day. I want to solve the problem at the source. Can anyone help me?
Avatar n tn Temporary loss of hearing in one ear - That weird buzzing silence comes for a few moments and then goes away. These symptoms have come and gone for the last year and a half. I was told it was stress by my doctor. My grandmother had a terrible brain tumor, so I finally convinced him to check. He thought it was my sinuses, so I had a sinus CT scan. Nothing except a possible cyst in my cheek.
Avatar m tn The claratin I used worked ok- mainly on perfume though, made life bearable. But when I switched to Zyrtec, which is for non-allergenic rhinitis, the change was amazing. Still get gnarly headaches at the first sign of mold; sneezing fits when neighbors cut grass or I empty out the vacuum; and perfume is nasty on my body. BUT on the whole - the right drug helps a lot.
720656 tn?1311043835 I know ribavirin half life is rather long, so will this continue until the riba is completely out of my system? Thanks so much for your help!
Avatar f tn Wow thats expensive Id try zyrtec instead it is way cheaper and when my doctor prescribed it to me i barely paid anything for it.. plus you can get it in alot of stores 20$ max for 30 days and its once a day pill.. Works for me id just consider trying cheaper things before you go for Zofran if its that expensive..
Avatar m tn I immediately took Zyrtec-D when the symptoms started, about 5 minutes after the drink. About four hours later the feeling had not gone away, and was gradually progressing. I went to a doctor nearby and he examined my throat. He did say that my tonsils were swollen and noticed the white gunk I had on my left tonsil, but he did not see anything wrong with my throat. I told him I have abnormally large tonsils and they usually look swollen normally because of the size.
Avatar f tn For my entire life I've been blessed with good health and no known illnesses, problems, or allergies. For the past six months I've been suffering from chronic hives. The first time I broke out into severe hives was July 2013. Prior to this, I've never had hives or been know to have any allergies. I saw the doctor a few times and the dermatologist. After trial and error with a few drugs, the only thing that would keep the hives down was prednisone.
1933354 tn?1323366434 But, the Atenolol has a much longer half life and I think it does a better job of holding me at a sufficient medicate level 24 hours a day by taking it twice a day. I also recall the Atenolol is more selective as far as the brain barrier is concerned - not sure about allergies. I have a lot of nasal congestion, which is year around, not seasonal.
