What is the difference between loratadine and cetirizine dihydrochloride? I've tried using both for my allergies. It says one is used to treat symptoms but loratadine is used to treat the whole allergy. Are there any other more effective choices that aren't too expensive?

sinatrafsc replied: "Loratadine is Claritin and cetirizine is Zyrtec. They are both anti-allergy medication. They both treat the whole allergy. They are in a class called the anti-histamines. These medications are your best bet. Clarinex is another one, but it's no more effective than Claritin or Zyrtec. Just make sure you drink plenty of fluids when you take them, because they can dry you out a little. If the allergies keep up, go see your doctor."

Alergy and cetirizine dihydrochloride? I am taking cetirizine dihydrochloride for alomost 4 years twice or thrice in a week. If I dont take this then my skin become redish and I feel itching. I want to know is this bad for health to take this medicine for long time? What can I do for this alergy problem? I am 25 years old.

Kemi replied: "I think your doctor can best answer this question. Since you have been taking it for so long, maybe your body has gotten use to the drug so that when you want to stop taking my you have rebound effects. Maybe you can try to decrease the doses. If you dont have smaller doeses, you can try to slowly stop taking the medication (spread out time period between doses so if you take it every other day, try every 3rd day then every 4th day). By doing this, you are not abruptly stopping the medication and your body wont be shocked. If this doesnt work, see your doctor."

Anyone ever taken the medicine Zetcet (Cetirizine Dihydrochloride)? Usually you would expect Cetirizine to be by Zyrtec. Is the Zetcet brand the same? Is it safe?

DR. MAG replied: "yes cetrizine is a generic name and any pharmaceutical company can produce it the same substance,the same side effects"

What's the difference between 'hydrochloride' and 'dihydrochloride'? I've got 2 packs of antihistamine tablets (Glapharm hayfever and allergy relief) - the packet Ive been using are called 'cetirizine hydrochloride'. I bought a new pack to use, thinking they were the same but these new ones are called ' cetirizine dihydrochloride' - what's the difference & will it be ok for me to take the new pack?

tota replied: "the (DI)"

two2fly replied: "The difference is the level of Hyrdogen in the compound. I see no reason you can't use the other package."

bob shark replied: "It may be a new formulation, using 2 hydroclorides in the molecule instead of one, or maybe they are just being more specific about the chemical composition than in the past. Take as Directed"

Lorna replied: "Hi. Hydrochloride: a salt, esp. of an alkaloid, formed by the direct union of hydrochloric acid with an organic base that makes the organic constituent more soluble. Dihydrochloride: a hydrochloride containing two molecules of hydrochloric acid. So basically, dihydrochloride contains one extra molecule of hydrochloric acid, so they've probably worked out a better formula for allergies. Good luck! Lorna"

spencer s california replied: "I think that "DI" equals two Hydrochlorides :)"

TweetyBird replied: "The most obvious difference is one hydrogen molecule. It's fine to take them."

Eternal replied: "Host consciousness: In the context of this question the pharmaceuticals are bio-equivalent. Your body will not know this difference, so don't worry. In many cases it could make a difference - but not this one. To all intents and purposes they are the same."

Baboo replied: "Both medications are the same and you can safely take the new one. The hydrogen level in both medications is THE SAME. In chemical naming, alot of times the (DI) naming is excluded because it is understood - in chemistry the same number of hydrogen atoms would surround the chlorine atoms (so the manufacturer left it out in the original medication). It is wrong to say that the number of hydrogen atoms changed unless the entire compound changed and was called something entirely different."

Cetirizine hydrochloride versus levocetirizine dihydrochloride? Usually, I'm prescribed levocetirizine (Xyzal) to treat my year-long allergies. I went to the doctor yesterday, and she prescribed me cetirizine instead. I'm not sure whether this was an accident (I specifically said I wanted levo) or whether she had decided, without telling me, to change my medication. What are the main differences between the two? I've tried lots of different types of antihistamines over the years, and Xyzal seems to work the best (none of them prevent my allergic reactions, but some supress it more than others)

Dizzle replied: "Xyzal is very similar to cetirizine(Zyrtec). Levocetirizine is a stereoisomer of cetirizine so they are very similar in structure. In some cases, stereoisomers can have differing effects however, there is really no proven benefit in taking Xyzal over Zyrtec(cetirizine). The real reason behind Xyzal being produced is because of the recent expiring patent for Zyrtec. It is now over the counter and therefore cheaper and not as profitable. Creating Xyzal is just a reason to make an expensive new antihistamine available by prescription only that has no proven benefit over its predecessor. Try the over the counter Zyrtec and see how you feel."

I am about to start the combined pill (Microgynon30) and i know some medicines affect it but....? do hayfever tablets with cetirizine dihydrochloride affect it? the hayfever tablets are antihistamines so im guessing they dont, especially as it is not mentioned on the pill packet! does anyone know?

suzannerice1964@btinternet.com replied: "I took that pill 20 years ago-it was awfull-and i dont take any other medicines-but that was a bloody awful experience(for me anyway)!! xx"

Kelly B replied: "No they don't affect the pill, I take the same antihistamines as you, the only tablets that affect the pill are antibiotics."

Matt S replied: "My girlfriend's on Microgynon and takes Sainsbury brand hayfever tablets. No problem s as such, thoguh she does have a problem with headaches during the 'rest' period. She's changing Pills to try and solve that tho."

Zoe replied: "I've been using this Brand for years and combined it with asthma puffs which didn't influence it. These also had a kind of antihistamines in it. To make sure, since everyone it different, ask your pharmacist to make sure. They have a record of what you use, so they should have informed you on that if it would affect it negatively. The only one I do know is antibiotics that don't go with any birth control pill."

jll1881 replied: "I also take a combined pill, although a different brand. According to my doctor, the only medications that can lessen the effectiveness are antibiotics and St. John's Wort, an OTC herbal supplement that may help treat depression. To double check, I'd recommend calling your local pharmacy - they can give you an answer right over the phone."

gemzalvn replied: "You're fine to continue with with your antihistamines. That pill made me vomit ++++ though..."

anyone with anaphylaxis are tips? hi, er this is weard to say but a cupple of months ago i am pritty sure i had an anaphylaxis reaction to well i dont know and another a few days last week my eyes swelled, the doctor give me cetirizine dihydrochloride, but i have no idea why hes give me this, he thinks it was a faint or a panic attack but i am 80% sure it wasnt. my symptoms were: itching tho nothing there, breathing difficulty, swollen eyes, had the worst stomach cramp ever (my mum was worrioed), felt sick, dizzyness. Tho i didnt go to hospital well i cry and get pannicy when i go near 1, i was ill a few days after. I have asthma, with allergies, tho my doc dont know what these allergies are cause he dont listen. with anaphylaxis can you get mild reactions? Thank you xx

aprilc232 replied: "I just did a study on anaphylactic shock. You get this from contrast media (barium or iodine) used in specific x-ray procedures. The mild symptoms are: localized itching, hives and maybe nausea/vomiting The most serious symptoms are: difficulty breathing, shock, cardiac arrest (death can occur) If you have allergies, you need to get tested by an allergist to pinpoint your causes. They can give shots or medications to ease allergies and asthma. It's worth the pain of a needle to be able to breath, live itch free, and cope with life's irritants."

Brian replied: "An anaphylactic reaction can occur in anybody toward any substance -- it's a potentially fatal allergic reaction. Most frequently, emergent treatment of an anaphylactic reaction is with epinephrine -- many people who are allergic to bees or wasps carry an epi-pen around with them, just to be safe. Hives, swelling, and difficulty breathing are indicative of an anaphylactic response -- but these are typical of most allergic reactions . . . for anaphylaxix, they are to the extreme. Cetirizine is an anti-histamine. The body has a chemical known as histamine in it. In an allergic reaction, of any size, histamine binds with receptors and results in increased heart rate, and often other issues such as sneezing, runny nose, watery eyes, and bronco-constriction. Cetirizine binds with the histamine receptors -- so, when the histamine flows around in the blood -- it doesn't have anywhere to attach -- so -- while there is still a physiological response to the allergen, it's much less. Cetirizine, loratadine, desloratadine, diphenhydramine hydrochloride, and chlorpheniramine maleate are all different types of anti-histamines -- they all work in basically the same way -- just to different degrees of effectivity and with varying side effects."

mooseny35 replied: "It depends on the severity of your allergy. Some people get mild symptoms and can recover quickly. Others won't recover from anaphylaxis unless given medical attention(epinephrine,steroids). When the eyes swell, this is the 1st sign of an allergic reaction. Try counteracting it with Benadryl. If breathing problems ensue, call 911 immediately or go to the ER. This all happened to my 3 year old. Her throat started to swell and she had terrible wheezing..it could be heard across a large room. It turns out that she has severe allergies to tree nuts. Go to your allergist and have him/her test for food allergies."

Mariya F replied: "I go into anaphylactic shock sometimes because i have an allergy that cannot be diagnosed. For hives, edema and diff, breathing, my doc prescribes Medrol, which is a very strong steroid, and i take an asthma inhaler when i feel breathing difficulty. However, this is a very severe condition, and if you really cannot breathe and have very high blood pressure during the attack, call 911. I feel your pain :("

Anyone know why I've had a blocked nose for a few years? For at least the last two years I've had a blocked up nose, some days one nostril becomes unblocked, but most of the time it's blocked, making me unable to breathe through my nose, I also feel tired all the time, no matter how much I sleep. I'm on Flixonase Aqueous Nasal spray, and Cetirizine Dihydrochloride, both have failed to help, I'm getting refered to the ENT (Ear Nose Throat) doctor soon, but this may takes some months before I get an appointment. Anyone know a reason for my blocked nose? The nasal spray was prescribed by a doctor. I've never suffered from nose bleeds, and have no foreign material in my nose. I was also tested for celiac disease, it came back negitive.

That's a Stupid Question replied: "You're cursed with what is known as a "really big booger". Pick it."

palmyrafan replied: "I would stop the nasal spray. That can lead to clogged nose. You could suffer from chronic sinusitis, allergies or have scar tissue built up due to sinus problems. In my case, it turned out to be tumors due to them spreading from the brain. I would check with an ENT and then get a 2nd or even 3rd opinion. Good luck!"

jef s replied: "Have you ever suffered from nose bleeds. It could be that you have had "foreign matter" blocking your breathing passages. Otherwise it's possible you have a problem with your septum (the division between nostrils). People who use cocaine have occasionally developed a problem in this part of the nose."

vintagechick replied: "Hmmm, that's sure a problem...In my family, lots of people had similar problems with congestion, fatigue, and the like... For many years, my mother especially, experienced these symptoms for many years. She finally whent to the doctor and got tested for food allergies; it turned out that she was a celiac. She was allergic to gluten, a protein found in wheat, barley and rye. This is a disease that dosen't always show up the first time, and every one reacts differantly...it may be worth a trip to the doctor to get a test done..."

Susan Yarrawonga replied: "Nasal sprays and antibiotics only give you a bit of short term relief and nasal sprays can actually damage your sinuses. Switching from mucus generating dairy products and red meat to soy milk and white meat will certainly help. Taking 6 high strength odourless 3,000 mg garlic oil capsules (Herron) every day will help. Garlic is both an antibacterial agent and an antimicrobial agent and is very good for people with sinus problems. Apple cider vinegar every day helps a bit as well."

my mite bites are getting worse? why? i got a lot lot of bite mites from sleeping in my friend's bed one night. i went to the dermatologist and she prescribed me some desonide lotion, cetirizine (oral) and an optional dihydrochloride if it is too itchy. i used the desonide and the cetirize for 2 days and my bites seemed to be getting better but on the 2nd night i took the dihydrochloride and when i woke up my bites were swelling up! they were really itchy and they were worse than ever! i don't know if it is because of the dihydrochloride or is it just a coincidence? why is my medication not working?

Richard B replied: "What you really need to do here is to call the dermatologist and tell her what's going on. Only she will know what's up and what to do about it."
