Can i take an antihistamine and a decongestant together
 flock to the pharmacy, searching for the best over-the-counter medication to help relieve their symptoms. When it comes sneezing and a stuffy, runny or congested nose there are many options, which usually settle into one of two camps: Decongestants or antihistamines. Which medicine is going to relieve your symptoms? Understanding what each medicine does is important in answering this question.

Decongestants  

A decongestant helps reduce swelling in the nasal passageways by shrinking the blood vessels. It helps you breathe easier because it relieves the pressure and improves airflow. The reason why you’re congested could be from a cold, allergies or a sinus infection.

Antihistamines 

Antihistamine blocks the body from releasing a chemical called histamine. Your body releases this chemical in response to an allergy. When too much histamine is release the body reacts through symptoms like sneezing, congestion, or a runny and itchy nose. Antihistamines are usually taken proactively to prevent these symptoms from occurring in the first place.  

Which one should you take?  

For true cold symptoms, a decongestant will provide more relief than an antihistamine. If you notice your “cold” symptoms occur at the same time each year (spring for examine), or are consistent year-round, you may actually have allergies that could benefit from antihistamine medication. Talk to your physician about your symptoms. Allergy tests can help determine if you are allergic to any environmental or food items.

What Is a Nasal Decongestant?

Just as the name states, a nasal decongestant relieves nasal congestion including a stuffy nose or runny nose. Congestion occurs when mucus blocks the nasal passages and when the blood vessels lining the nose become enlarged.

Congestion is often caused by common colds, upper respiratory infections, or allergies. Most decongestants work by shrinking the blood vessels so you can breathe more easily. Nasal sprays are commonly used decongestants.

What is an Antihistamine?

A histamine is a chemical created by your immune system. When a histamine overreacts to an allergen, it causes symptoms of an allergic reaction such as sneezing and coughing.

Antihistamines can be prescription or over-the-counter medications that target the symptoms of an allergic reaction. “Anti” means “against” so the medication works to block or work against the histamine reaction. They may also treat the symptoms of the allergic reaction as well as some cold, anxiety, or other problems.

Antihistamines are broken into two categories. H-1 blockers treat allergy symptoms while H-2 blockers treat symptoms of acid reflux, nausea, vomiting, and motion sickness.
