I'm curious as to what hayfever remedies are best?

Allergy medications: I suppose you refer to seasonal allergic rhino conjunctivitis treatment, which we commonly refer to as seasonal allergy symptoms or hay fever. You can try otc antihistamine. However, those are weak medications. If you are still symptomatic, you might want to see your doctor to get stronger and more efficient medications.

Several: There are several treatment options for "hayfever" including oral antihistamines, nasal steroids and nasal antihistamines as well as allergy vaccines therapy.
