Do not reduce, increase or stop taking any prescription medication until you discuss this with your doctor.
Do not add a supplement until you discuss this with your doctor as each person and their list of medications and conditions varies.
However, I would like to bring up the topic of alternative/adjuncts for allergies.
As a life-long allergic asthmatic I can tell you that I have been sold a lot of bunk and unworthy products in my life. Every kind of intuitive and alternative practitioner you can think of has tried unsuccessfully to stop my allergic asthma. My allergies are particularly annoying because I am severely allergic to cats, dogs, feathers, and mites. Pet-friendly, feather-pillow using hotels have almost killed me.
So, when I recommend you discuss a product with your doctor, it is not without substantial personal angst.
So, it is with trepidation that I recommend you talk to your doctor or health care professional about allergy reduction and choline (especially the dosage and quality). Some choline products are better absorbed not through the company brand but through the chemistry.
Some studies are beginning to show that choline may be helpful for skin allergies and asthmatics. Suffering from both, I gave it a try. For me and I can only speak for myself, I can’t remember the last time I used a rescue inhaler even though I visit homes with pets. I still take two prescription pills for asthma, but for me, the choline has made me more comfortable and reduced rescue use.

When one natural substance both reduces allergies and increases brain health, it has to be on your list to discuss with your healthcare professional. Be careful to tell your doctor which type of choline product you are taking so the dose can be adjusted properly.
