Hello and hope you are doing well.
Drops or creams work best locally, but there could be minimal absorption, which could be very minimal for therapy. But it could trigger an allergic response.
Hope this helped and do keep us posted.
Yesterday, I asked: Can antihihistamine Eye Drops, enter your system through your eyes? While the question seems somewhat idiotic, I am highly allergic to antihistamines. They knock me out for extended periods of time, by making me lethargic, and extremely drowsy and sluggish. I used an antihistamine eye drop yesterday, and, shortly, had all the above symptoms. My question is simply, can one's system absorb antihistamines through the use of antihistamine eye drops?
