Winter is in full swing and as the cold weather intensifies, so do allergens which could take a toll on your health. If you are suffering from severe seasonal allergies like watery eyes, scratchy throat and runny nose, you should take antihistamines. Antihistamines could help you reduce these symptoms, but remember to use them safely and never to overdose yourself! Overdosing yourself can trigger adverse side effects. Therefore, we have curated an essential antihistamine 101, which covers everything you need to know about the medicine. So without any further ado, let’s get straight into it.

What are Antihistamines?

Allergens are substances that can flare up allergic reactions in our body. Some popular allergens include pollen, pet dander, dust and even food and some medicines. As soon as an allergen gains entry in our body, our body discharges histamine. Histamine is a causative agent of allergic symptoms. That’s when antihistamines come into play and block the symptoms of histamine.

Antihistamines are popular over-the-counter medications that relieve you from allergic symptoms. You can find these medicines at almost any pharmacy. They come in various forms including syrups, tablets, lotion, nasal sprays, and even eye drops.

Types of Antihistamines

Antihistamines are classified into the following two types including:

First Generation Antihistamines
These medicines are older generation antihistamines, also known as sedating medicines. They cause increased drowsiness and fatigue.

Newer Generation Antihistamines
This category includes second and third generation antihistamines which are also called non-sedating medicines. They don’t cause much drowsiness and are used much frequently.
