When taking two antihistamines, it is important to consider the dosage and side effects. Different antihistamines contain different active ingredients and strength, so it is important to read the label carefully. Taking two separate antihistamines can increase the chance of side effects, such as drowsiness, dry mouth, dizziness, and headaches. It is always best to consult a doctor or pharmacist before taking any form of medication.
Side Effects
Taking two antihistamines can lead to an increase in side effects, such as drowsiness, dizziness, and dry mouth. Taking two antihistamines can also increase the risk of an allergic reaction, such as difficulty breathing, hives, or swelling of the face, lips, tongue, or throat. In some cases, taking two antihistamines can lead to an increased risk of developing an irregular heartbeat.
Drug Interactions
Taking two antihistamines can also increase the risk of drug interactions. A drug interaction occurs when two or more drugs interact with each other, resulting in unexpected and potentially dangerous side effects. It is important to discuss all medications with a doctor or pharmacist before taking them to reduce the risk of drug interactions.
Overdose
It is possible to overdose on antihistamines, and taking two antihistamines increases the risk. Symptoms of an overdose can include confusion, difficulty breathing, and loss of consciousness. If an overdose is suspected, it is important to seek medical attention immediately.
