When you go out in the daytime you start sneezing but when you come back in at home or finds a shadow then sneezing stops, so this condition or so called infection is known as Allergy.

Allergies are very annoying and disturb and can reduce the quality of life of the person suffering the allergic reaction. Allergies are often life-threatening. Normally many persons suffer from allergies which are not everyday allergy but seasonal allergy. Many people use decongestants and antihistamines to get through the allergy season.

Allergy can cause the sinuses, lining of the nose, ears and even the lungs to swell and to become stuffy. This can be a very difficult time for the sufferer, as the nasal drainage can be annoying. Using medicines for allergy can become even more annoying as they have many side effects. There are many restrictions to use the medications as the side effects are very high and people suffering from the high blood pressure should be very careful before using any of the medicine for the allergy.

The best way to avoid the allergy is to avoid contact with the source, item or material causing allergy; normally people don't take any medication for the allergy but it is better to avoid contact with the materials and to take proper medication through a good specialized doctor. It is very difficult to stay away for the symptoms causing the allergy as you can't spend whole spring season just sitting in your room. Antihistamines are very effective medication for allergy but have many side effects and some time side effects become much more dangerous then the allergy which was our primary problem. But the side effects are also concerned with the body and characteristic of the person's body, so if someone is having problem using an anti allergy but it may happen that it works fine with another person. So you should go to a physician and ask for proper advice with tests of your body and then go a head for the medication.
