Negative Side Effects of Antihistamines
Antihistamines are commonly prescribed medications used to treat allergies, hay fever, and cold symptoms. Although these medications are usually effective and well tolerated, they can cause a variety of side effects, ranging from mild to severe. It is important to be aware of these possible side effects before taking antihistamines.
Drowsiness: One of the most common side effects of antihistamines is drowsiness. This can affect the ability to drive, operate machinery, or concentrate on activities that require alertness. People taking antihistamines should avoid activities that require concentration or physical coordination until they know how the medication affects them.
Dry mouth: Many antihistamines can cause a dry mouth. This can cause difficulty in swallowing and speaking, as well as an unpleasant taste in the mouth. Drinking plenty of water and avoiding alcohol can help reduce the symptoms of dry mouth.
Blurred vision: Antihistamines can cause blurred vision, which can impair vision when driving or operating machinery. It is important to be aware of this side effect before taking antihistamines and to take extra precautions when driving or operating machinery.
Headache: Headaches can be a side effect of antihistamines. These headaches can range from mild to severe and may require medical attention if they persist.
Constipation: Constipation is another common side effect of antihistamines. This can be caused by the medication slowing down the gastrointestinal tract. Drinking plenty of fluids and eating a high-fiber diet can help to reduce the symptoms of constipation.
Restlessness: Some people may experience restlessness or agitation when taking antihistamines. These symptoms can be uncomfortable and can make it difficult to relax or sleep. If these symptoms persist, it is important to speak to a doctor.
Allergic reaction: Antihistamines can cause an allergic reaction in some people. Symptoms of an allergic reaction can include difficulty breathing, rash, hives, swelling, and itching. It is important to seek medical attention immediately if any of these symptoms occur.
