There are 2 kinds, one is made last for 12 hours, the other is for 24 hour relief. It should specify which one it is on the front of the box in a small circle next to the name of the medicine.
Medicines should be used according to the manufacturer's instructions except on the advice of a trained doctor or pharmacist. Persons tolerance for that drug do vary, however, and some persons find that they need to take it after a delay of 17 or 18 hours, but taking it every 12 hours would be excessive. However, this is something that should be discussed with a patient's doctor or pharmacist.

Drinking wine is often a trigger for headaches. Whether or not it is safe to take Claritin after your wine depends on many factors. For best advice, ask your physician or pharmacist. _________________ The use of alcohol and claritin is not associated with any documented adverse effects, except increased drowsiness for some people. However, it is always a good idea to be cautious while combining alcohol with any medication! Of note, headaches are a common side effect of claritin use...documented to be as high as 12%.
It take 12 to 14 hours.
If you're taking Claritin, not Claritin-D, you can take basic allergy medications like Benadryl. The side effects include drowsyness, etc. If you're looking for an alternative, Zyrtec has come out on the market, and it has 12- and 24-hour varieties. I've heard that taking allergy pills (Claritin, Zyrtec, etc...) are more effective when taken twice daily in people that metabolize the medication more quickly. It's something to try out. Get the Claritin 12-Hour and try that for awhile to see if it works better for you. Otherwise, consider seeing your physician about Allegra, an allergy medication that is still available via prescription or talk to him about using an intranasal administered antihistamine together with your current Claritin.
