Nasal saline irrigation is possibly the most affordable method of treating allergic rhinitis. Allergy shots also save money in the long run, though they may be more expensive at the beginning, reports About.com.
Allergy shots come the closest to curing the allergy so they significantly reduce the amount of allergy medications needed, according to About.com. Chlor-Trimeton and Benadryl are used to treat allergy symptoms such as runny nose, sneezing and itching.
Claritin is also an option for treating similar allergy symptoms. Some over-the-counter antihistamines include chlorpheniramine, diphenhydramine and loratadine, which are the active ingredients in Chlor-Trimeton, Benadryl and Claritin, respectively, reports WebMD.
