Non sedating antihistamines otc

Many prescribed and OTC allergy medications have antihistamine combined with decongestant in order to more broadly cover nasal allergy symptoms.For many years the decongestant component was represented by pseudoephedrine, (Sudafed, the D component of Claritin-D and Zyrtec-D, and many other brands) phenylpropanolamine (previous brands included Entex LA and many OTC allergy medications) and phenylephrine (the decongestant that has replaced pseudoephedrine in many OTC allergy medications currently available).Antihistamines also can be used on an as needed basis for those who experience occasional symptoms or symptoms triggered by exposure to certain irritants such as animal hair, plants, medications, and food products.

Antihistamines work by blocking the action of histamine which the body produces as part of its natural defences.

Although newer antihistamines have a lower risk of drowsiness, doses taken above the recommended levels may cause not only drowsiness but other serious side effects.

If you have questions or are uncertain about how a medication should be taken talk to your doctor or pharmacist.

You probably know that purchasing an OTC oral decongestant in major chain drugstores may require two forms of ID and your signature.

Third, the sales of many older (first generation) prescribed and OTC antihistamines and decongestant combinations have plummeted since the newer generation medications have flooded the market (Claritin, Claritin-D, Allegra, Allegra-D, Zyrtec, Zyrtec-D etc.).
