How many weeks does it take for claritin (loratadine) 10mg to work? How long should I give it a try before deciding to switch to a different antihistamine?

Try for a few days: Antihistamines begin to work in less than an hour but a person may not feel significant relief for a few days. Claritin tends to be one of the weaker non-drowsy antihistamines. Others available without a prescription are Zyrtec, Allegra and Xyzal. If antihistamines are still not working then an evaluation by an allergist can be helpful to determine the cause of symptoms ...Read more

How long should it take for my Claritin (loratadine) to work?

Up to 1 hour: Claritin (loratadine) can work relatively quickly in most people. That is, it usually works within 30 minutes. However, in some people it may take up to 60 minutes to have its full effect. If it is not working within that time, or if the duration of effect becomes less and less, seeing an allergy specialist for allergy testing would be recommended as other treatments may be more effective. ...Read more

How long does it take for Claritin (loratadine) to take effect on hives??

3 days to reach peak: Claritin (loratadine) (loratidine) takes 3 days to reach a steady state, so it could take that long for it to work on hives. Other non-drowsy antihistamines are a better choice: Allegra (fexofenadine) reaches peak effect within 2 hours and Zyrtec (cetirizine) reaches peak effect in 1-2 hours. If you see no benefit at all within 5 hours of taking these, they probably will not work for you. ...Read more

How much time does it take Claritin (loratadine) to work?

Who knows: Work for what? Claritin supposedly starts working within 90 minutes. But Claritin is also the weakest binding antihistamine sold over the counter. Personally, I feel Claritin is a waste of money. Use a stronger antihistamine like fexofenadine or Cetirizine which cause minimal to no sedation. Use Benadryl (diphenhydramine) only at nighttime because it can make you drowsy. ...Read more

My husband swears Loratadine doesn't work for him unless he takes 20mg BID. What is the highest SAFE dose take?

My husband swears Loratadine doesn't work for him unless he takes 20mg BID. What is the highest SAFE dose take?

Recommended dose: The recommended daily dose is 10 mg. It is fairly a safe medicine, but side effects may arise in high doses. It seems like he is tolerating the 40 mg/day dose. The high dose definition may vary from patient to patient according their body tolerance. As he requires a large dose, he might benefit from adding different class medicine, so that he can avoid the side effects from unconventional doses. ...Read more

What are the differences between loratadine and desloratidine in how well it works or how long it lasts?

What are the differences between loratadine and desloratidine in how well it works or how long it lasts?

Take one, get both: When you take loratidine, your liver breaks it down to desloratine which is actually responsible for the anti-histamine effects you need. Desloratidine has a much longer effect (28 hours) than loratidine (8 hours) which is why loratidine lasts such a long time. ...Read more

How does Claritin (loratadine) work? I'm wondering what would happen when I take two, how does it effect my body. And if I take one and I still feel itchy, would taking two help control my symptoms more?

Dr. Al Hegab Dr. Hegab
2 doctors agreed:

An antihistamine: Claritin, (loratadine) like all other antihistamines, blocks histamine receptors thus prevents histamine release, one major mediator, out of many, that cause allergy symptoms. If one tablet isn't controlling your symptoms, better see your doctor, you may need some other medicine ...Read more

Is it safe to take loratadine long term, everyday, for allergies?

Is it safe to take loratadine long term, everyday, for allergies?

Prob ok: Antihistamines have been around for decades, and certainly many more potent than loratadine. They say worldwide the most common drug taken is diphenhydramine, mostly for the sedative properties (as a sleep aid). Antihistamines can affect certain types of glaucoma, and accentuate urine retention in those with prostate issues and dry mucous membranes, but usually not so much with loratadine per say. ...Read more

My dr prescribed Claritin (loratadine) for a skin reaction, but its no longer effective. Can I take a second dose so I can get a decent night's sleep?

Claritin (loratadine): Rather than doubling the dose of Claritin (loratadine) it may be wiser to try a different antihistamine until you can get back in and be seen. Not knowing what the condition is it is difficult to know exactly what to do. I suspect this may be chronic hives. There are certainly other things to do if it is. You may want to see an Allergist, ...Read more

If I take Claritin (loratadine) but it doesn't work because I have a more intense cold with allergies, can I take something else tonight like Benedryl?

Since you have not mentioned any of your symptoms from which you seek relief, Its not possible to make specific recommendation.
