Many cases of hay fever can be controlled using over-the-counter medication available from your pharmacist, such as antihistamines, which can help prevent an allergic reaction from happening and corticosteroids (steroids), which help reduce levels of inflammation and swelling.

Excerpt: The commonly used hay fever treatment options are: antihistamine nasal sprays, antihistamine tablets, steroid nasal sprays, and eye drops. If your hay fever symptoms are not controlled on the medication that you are taking after 2-4 weeks, you should discuss this with your doctor. You may need to try a different treatment or add in another treatment. If you are taking hay fever medication regularly and your hay fever is well controlled on your current treatment, you should continue this treatment until the end of the pollen season.
