Cimetidine, for example, is notorious for antagonizing androgenic testosterone and DHT receptors at high doses.Examples include: receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of histamine.He told me that is no need to go for blood analysis. I'm staying on them this time (at night I take Allegra 180mg, Atarax 50mg, Doxepin 20mg, Xyzal 5mg, Ranitidine 150mg.) Yes, that is a ton of antihistamines, but my allergist discovered that if I take a antihistamine cocktail every day, I stop breaking out.

They minimize sedatory effects due to their focused effect on peripheral histamine receptors.

Sedating antihistamines oppose the effects of histamine on H1 receptors in your brain, which is why they cause sedation and drowsiness.

Antihistamines are very good at relieving symptoms of an allergic reaction, such as: First-generation antihistamines were developed more than seventy years ago and are still in widespread use today.

They act on histamine-1 receptors in the periphery and are unlikely to penetrate the brain, so are less likely to cause side effects or interact with drugs.

Most second-generation antihistamines do not cause drowsiness, although some (such as cetirizine and fexofenadine), may be more likely to do so at higher dosages.
