Mast Cell Inhibitors are drugs that help to stop any release happening with histamine plus any chemicals that might be the cause of your allergy problems; such as when someone might come into contact with pollen that's considered an allergen.

Mast Cell Inhibitors prevent certain symptoms such as a runny nose and possibly itchy eyes. Cromolyn sodium is the main ingredient used in Mast Cell Inhibitors. People start using these sprays or medications a couple of weeks before pollen season begins.

When you are taking a Mast Cell Inhibitor, you usually take it every 8 hours depending on what kind you have and what your doctor says. If you are on other drug medications it should not interfere with them.

Side Effects:

- Burning
- Stinging
- Redness
- Severe swelling with eyes
- Sneezing
- Nosebleeds
- Nasal congestion

While there are a lot of side effects most people usually don't get them and find Mast Cell Inhibitors to be very helpful.
