By prescription: But Claritin D is OTC and is almost as effective.Clarinex (desloratadine) is des-loratadine and Claritin is loratadine

You are correct, Dr Kahn! I misread Claritin for Clarinex. Probably because I am taking Claritin-D as we speak. Also, a doc can write a 30 day px for Claritin-D and it will override the 2 week limit that some states have for otc purchase of claritin-d or like drugs.

You have to sign: The D means it contains pseudoephedrine which is a stimulant drug that can be abused. In some states you have to sign for it and show a driver's license. It is also available by prescription. Do not take if if you have high blood pressure or heart disease for sure. Read the package for other precautions as well. I am not sure if you have to sign for it in every state. Your pharmacist knows.

I did misread this as Dr. Kahn clarifies. And Clarinex is prescription You have to sign for Claritin-D, still. Your doc can also write a px for 30 days of Claritin-D and then you will not have the 15 pill limit imposed by some states, like KY on otc Claritin-D.

The first time: Time from ingestion to full activity is about 1 to2 hours. The same dose will act in the same way each time you take it, but may not seem as effective if your exposure to allergen is greater.

Allergies: It may work immediately, it could take day or weeks. It depends on the enviroment/winds (some weeks are worse than other), the severity or mildness of your allergies. There is stepwise approach for allergy eval & treatment (many time requires combination of med, allergy testing etc. Depends on patient). Usually I do follow ups 3-4 weeks at time to allow med to work and weather to change.

Seasonal allergies: Clarinex is another form of the antihistamine medicine-claritin. The generic name is loratidine. It helps with allergies, like hay fever. There are many current examples of medications which have become generic, so drug companies try and make an alternative form that they can market with a brand name. If you take claritin-your body converts it into clarinex. Another example is Nexium (esomeprazole) and prilosec.
