What are the Top Five Antihistamines?

Antihistamines are medicines that reduce the effects of histamine, a chemical released by the body in response to an allergen. Histamine can induce itching and swelling as well as trigger sneezing and runny nose through its effects on blood vessels and nerves. Histamine is produced by white blood cells called mast cells, which release it directly when they encounter an allergen. Antihistamines work by blocking receptors called H1 histamine receptors, which prevent histamine from having its effect on red blood cells, nerves, and vascular smooth muscles. Common side effects include drowsiness, dry mouth, dizziness, blurred vision, nausea and increased appetite. To help you choose the right antihistamine, we have compiled the following information.

What are the benefits of using Antihistamines?

Antihistamines can ease the symptoms of allergies. They can reduce itching, runny nose, sneezing, and swelling of the eyes, nose, and throat. They can also help you sleep better if you have allergies that wake you at night. Antihistamines are particularly useful in treating allergies to pollen, animal dander, and certain foods such as peanuts. They can be used to treat grass allergies with a few limitations. They can be taken as a preventive measure before you know allergies are coming. Antihistamines are not just useful for allergies though. They can also be taken to treat a condition called “cough” where the cough reflex is overactive. They can also be used to treat motion sickness, nausea, tinnitus, and vertigo.

Benadryl is an antihistamine. It works by blocking the effects of histamine, which is responsible for many of the symptoms associated with allergies. It is commonly used to relieve itching from insect bites, allergies, and other rashes. It is also used to treat insomnia when accompanied by a cough or runny nose. Benadryl is very popular, and for good reason. It’s inexpensive, easy to find, and works for many different types of allergies. It can also help with occasional sleeplessness, especially when accompanied by a cough or runny nose. The only real drawbacks are that it can make you a little sleepy, and it may interact with certain medications. Other antihistamines, such as Claritin, maybe a better choice if you’re taking certain medications.

Claritin - Good for seasonal allergies and asthma

Claritin is an excellent choice for general allergies and asthma. It is available as a non-drowsy formula, unlike other allergy meds.

It’s effective for both indoor and outdoor allergies and can help reduce the severity of asthma episodes.

Zyrtec may interact with certain medications such as Coumadin. If you’re taking this medication, be sure to talk to your doctor before taking Zyrtec.
