About one-third of adults and children have allergies. That’s why many people take medications that block the body’s response to histamine, a chemical your immune system releases when it encounters allergens like pollen, pet dander, mold, or dust. Using these medications (called antihistamines) as directed is vital for long-lasting relief.
Below, we’re sharing everything you need to know to safely use antihistamines. Also, be sure to visit Srinagesh Paluvoi, MD, FAAP, FACAAI, and our team at Allergy & Asthma Affiliates in Lansdowne or Gainesville, Virginia, to learn which antihistamines may be right for you.
Histamine is what causes classic allergy symptoms like sneezing, itching, watery or itchy eyes, and a runny nose. By blocking that response, antihistamine medications can calm things down.
But not all antihistamines are the same. Some cross into the brain more easily, which might make you feel drowsy. Other options are less sedating, so they’re better for daytime use.
Some antihistamines are commonly available over the counter, while others require a prescription.
Antihistamines aren’t just for seasonal allergies. They help minimize the following symptoms and more:
Using antihistamines to eliminate symptoms caused by allergic reactions can dramatically enhance your quality of life.
Antihistamines are often available in the following forms:
It’s important to take antihistamines exactly as instructed by Dr. Paluvoi. You might need to take an oral form with water or food, or take certain antihistamines before bed.
Talk with Dr. Paluvoi about possible side effects linked to antihistamines. Examples may include dry mouth, constipation, decreased appetite, headaches, or drowsiness (with some). He discusses what to expect and ways to minimize any side effects.
The dose of antihistamine that’s best for you depends on your age, weight, and the type of antihistamine you take.
You might need to take it daily to keep symptoms at bay, use antihistamines only when you develop symptoms, or take an antihistamine before exposure to an allergen — such as pet dander at a friend's house. You may need to take your medication more than once daily.
To learn if you have chemical allergies, food allergies, or other allergies, consider asthma and allergy testing with Dr. Paluvoi at Allergy & Asthma Affiliates. He determines which treatment can help you best manage your symptoms long term and if you’re a candidate for antihistamines.
