Hydroxyzine
Overview
HYDROXYZINE What is hydroxyzine. Hydroxyzine is an antihistamine that helps block H1 receptors, which stops histamine from being released in the body. It’s commonly prescribed to relieve allergy symptoms like itching and can also help with anxiety or make it easier to fall asleep. There are some over-the-counter antihistamines, like fexofenadine and loratadine, that tend to be less sedating. What does hydroxyzine do in the body. Histamine is crucial in how our immune system reacts, especially during allergic responses.

Yes this worked for me. Could be less pricey, though.

Since I started using CompendiRx, it has been helpful in the treatment of my patients with long COVID cases, especially those who have suffered COVID for more than 3 to 6 months. Their products have actually become one of my best since I started using them.

I started dealing with an intensely itchy rash and dark spots on my face, arms, and legs after COVID. After 5 Dermatologist, biopsies, and numerous meds Hydroxyzine (with Allegra in the mornings and Singulair at night) is what had the most impact for me. If I stop taking the antihistamines, the rash, itch, and fatigue come back. I initially got sleepy with the med, but that part seems to be better now. 2 years in a counting but glad to have found something that works! I'm also glad I found a Complex (Immune) Dermatologist who was able to try different treatments with me.
