No Drug Interactions for Mast Cell Inhibitors

Mast cell inhibitors are a highly effective type of drug that can treat hay fever symptoms. They prevent the mast cells to produce histamine, a chemical responsible for the discomforts arising from allergic reactions such as runny nose and itchy eyes.

Cromolyn sodium (in the form of Nasalcom, Crolom) is the solution for mast cell inhibitors. Since hay fever is normally caused by pollens released by certain pollen-bearing trees, grass, weeds, and flowers, cromolyn sodium must be started 1-2 weeks before the pollen season starts, and must be maintained on a daily basis all throughout the pollen season. While the response is not as strong as corticosteroid nasal sprays, it is more effective than antihistamines.

Since these drugs have little or no effect beyond the area where they are applied, they are less likely to interact with other drugs. This means that many people can use these drugs without worrying for complications with other medications. However, people who are allergic to any components of the nasal spray or eye drops must not take them.

In addition, remove your contact lens when applying eye drop form of these drugs because some residue of the drug may cause a chemical reaction in the lens that can irritate the eyes.
