About prescription antihistamines
Antihistamines are medications designed to treat allergy symptoms. They’re often prescribed to help treat histamine-mediated conditions, but they’re also used for other conditions. There are two types of prescription antihistamines.
What antihistamines treat
The most common condition treated with antihistamines are allergies and allergic reactions. The drugs are designed to bind to, and therfore block, H-1 receptors (histamine-1), which play a crucial role in allergic reactions. These prescriptions or over-the-counter products are effective treatment options for a wide range of allergies, from seasonal to insect stings or bites, conjunctivitis, hives, and hay fever.
Over-the-counter antihistamines can alleviate symptoms like:
-
Runny nose
-
Nasal congestion
-
Itchiness
-
Nasal swelling
-
Skin rashes
-
Watery and itchy eyes
-

Hives
Antihistamines can significantly improve these symptoms, helping patients feel better during the day and get enough shut-eye at night. These medicines that can alleviate allergy symptoms include capsules, pills, and liquids, including eye drops, nasal sprays, and chewable tablets. In medical settings, a healthcare professional can use injectable antihistamines forms. Injectables are often used when there is a severe life-threatening allergic reaction.
Other conditions are also treated with antihistamines, including insomnia and motion sickness. Taking antihistamines can prompt drowsiness by operating against histamine. In some circumstances, these medicines can mitigate sleeplessness when traveling.
