Avoidance, which is almost impossible, unless you live in a bubble! lol!
Really, my best advice would be holistic allergy elimination.
You could go to your doctor and get a prescription for the allergy, but this is
not a cure.
Check for your area Practitioners or Doctors who have training in "Allergy
Antidotes" or NAET (Dr. Nambudripad's Allergy Elimination Techniques),
both drug-free methods.
Hope this helps.
Hello and hope you are doing well.
Try to maintain an allergen-free environment. Substitute all synthetic and cool materials with cotton ones. Remove all dust-collecting household articles like carpets, bedspreads etc. Alternatively an allergy specialist may try to identify the offending allergen and try to desensitize you. If you haven't undergone formal allergy testing, that might be beneficial.
Hope this helped and do keep us posted.
