Do you sometimes get red, itchy eyes, runny nose, or watery eyes from dust or pollen? This can be a very annoying experience. So, one of the most common medications your doctor will prescribe to control the itchy eyes caused by allergies is Pemirolast eye solution.
Simply put, what is this Pemirolast?
Pemirolast is a liquid medicine that is applied to the eyes, that is, an eye drop. Its main function is to prevent itching in the eyes caused by allergies. When something allergic enters your eyes, the cells in our body release chemicals like histamine. These chemicals are what cause the eyes to itch, become red, and swell. Pemirolast eye drops stop the release of these chemicals. Therefore, you will experience less allergy symptoms. In Sri Lanka, this medicine can be found under brand names like Alamast.
