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

  • Sneezing

  • 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.

Antihistamines FAQs

How should I take antihistamines?

The doses will vary from patient to patient. Stick to your doctor’s instructions or follow the label. When taking the medicine by mouth, you can take it with a glass of water, milk, or food. This can help minimize stomach irritation. If you are using an extended-release tablet, then you need to swallow it whole. Avoid crushing, chewing, or breaking the product

Who shouldn’t take antihistamines?

You shouldn’t be using antihistamines if you are also using specific other prescription drugs such as erythromycin, which is an antibiotic or drugs for alleviating fungal infections.

When your doctor suggests you use antihistamines, be sure to let them know of any other medicines you might be using, including other health conditions, you might have such as high blood pressure, thyroid, heart disease, glaucoma, or BPH.

How long does it take for antihistamines to work?

Most of the time, the effects of a table start to kick in in about half an hour. They reach their peak in efficiency in roughly 2 hours. Whether you are using nasal sprays, eye drops, injectables, liquids, or chewable tablets, their efficiency will vary. You will know if the product is working when the symptoms of your allergy start to subside or are completely relieved.

What should I avoid with antihistamines?

Some medicines don’t mix well with antihistamines. Drugs that could trigger problems with this type of treatment are antidepressants, indigestion, or stomach ulcer medicines, as well as cold and cough remedies that also feature an antihistamine.

When treating an allergy with a product like this, avoid drinking alcohol. Alcohol can increase the odds of drowsiness and make you sleepy. Other consumables, foods, and drinks don’t affect most antihistamines. However, be sure to check the leaflet for other things you should avoid.

What do antihistamines do to your body?

When you are allergic to something, the immune system goes into an overload in an effort to protect the body from infection – it sees the allergen as a threat. The immune system reacts to something that is not supposed to be harmful, like pollen. So, the immune system ends up releasing too much histamine. This is the reason behind the throat, nose, sinuses, lung inflammation, and other reactions. Antihistamines block the effects of histamine. Therefore, curbing its impact. 

Which drugs are antihistamines?

These drugs are divided into two primary types: non-sedating and sedating antihistamines. Sedating anthisitamines can make you feel sleepy since they move with ease from the blood to the brain. For example, chlorphenamine maleate and promethazine hydrochloride. These are often first-generation antihistamines. Non-sedating are the newer variants that have lower odds of making you feel sleepy, such as acrivastine and loratadine.

What is antihistamine used for?

Antihistamines are drugs you use to stop the symptoms of allergies. They are mainly used for symptoms like itching, skin rash, sneezing, hives, allergic asthma, allergic conjunctivitis, insect bites, and stings. Some patients might also use them for travel sickness.
