Antihistamines are designed to treat allergy symptoms by blocking histamines. According to Mayo Clinic, it is “a symptom-causing chemical that is released by your immune system during an allergic reaction.” Histamines are the culprit for reactions such as sneezing or itching when you are exposed to common allergy triggers like pollen, dust, pollution, and more.
There are a few available over-the-counter (OTC) options when it comes to antihistamines and your doctor will prescribe what is appropriate for your condition. The common perception about allergy medications is how they make you feel sleepy and tired, so it is essential to know how they can affect your overall health and avoid any undesirable effects.
There are two common ingredients found in your go-to allergy medicines—cetirizine and loratadine. While these antihistamines both help relieve your allergy symptoms, it is also best to know their differences and how they can affect your health.
Cetirizine
Cetirizine is a type of antihistamine that is commonly used to treat symptoms of hay fever, food allergies, hives (urticaria), seasonal and perennial allergic rhinitis, and other allergies conditions. It is known to be a non-drowsy option compared to other allergy medicines, however, it can still cause some drowsiness in others. Possible side effects include headaches, drowsiness, dry mouth, sore throat, coughing, and more.
Loratadine
Just like cetirizine, loratadine is classified as a non-drowsy antihistamine that helps relieve hay fever symptoms like sneezing, coughing, runny nose, and itchy/watery eyes. It’s also used for patients with allergic rhinitis, eczema, and chronic urticaria. Common side effects include headaches, drowsiness, and more.
One of the general rules of taking allergy medicines is that you should not drink them with alcoholic beverages to avoid feeling drowsy. Some people may still experience drowsiness even if they are taking these medications, so it is best to stay at home and rest to avoid any accidents. Medicines may affect individuals differently and their effects on your symptoms may vary. It is best to rush to your nearest hospital for severe allergic reactions.
Regardless of what is prescribed for your condition, it is essential to disclose to your doctor any kind of medication allergies that you may have. Keep in mind that you should follow your doctor’s advice in taking your medicines. Reading the product inserts that are usually included in your medicines can also help you understand how your medications work.
