Why might my medication (Fexofenadine) no longer be as effective despite taking it for years?

If your medication is no longer as effective as it used to be, I suspect it is because your sensitivities have widened a little over the years. This could cause more severe symptoms that are harder to manage.

A herbal remedy such as our Luffa tincture could be very beneficial in managing your hayfever symptoms, but I think it is important to think about diet as well. Caffeine can make hayfever symptoms worse, for example, as it is pro-inflammatory. Dairy products and highly processed foods are also known to be problematic, especially in regards to nasal symptoms.

Opt for fresh produce where possible and load up on things like nettle tea and vitamin C which are natural antihistamines and anti-inflammatories.
