Welcome to HCM.
For
hay fever, the best approach is to avoid allergens and other triggers (such as smoke and dust).
There is always some triggering factor for this type of hives.
Be watchful for triggering factor.
Go for allergy test to find out the allergen.
Antihistamines are much more effective when taken daily during your allergy season rather than only on days when you have symptoms.
Switch over anti histaminic from zyrtec to fexofenedine,desloratidine.
The FDA has approved the prescription antihistamine nasal sprays
azelastine and
olopatadine to relieve the symptoms of seasonal
allergic rhinitis. More severe allergies may benefit from nasal sprays containing steroids, which are strong anti-inflammatories and help with many allergy symptoms.
Take B12,
folic acid,zinc,vitamin-c,e and other supplement to boost up your general health.
Keep in touch with your doctor.
