If you are experiencing severe hives and are considering taking an increased dosage of Zyrtec (cetirizine), it is essential to consult with a healthcare professional before doing so.
Zyrtec is an antihistamine commonly used to relieve allergy symptoms, including hives (urticaria). The usual recommended dosage for adults is 10 mg (one tablet) once daily. Taking two Zyrtec tablets (20 mg) in one day may not necessarily provide additional benefits and could increase the risk of side effects.
Taking higher than the recommended dosage of any medication can be dangerous and may lead to adverse effects. Some potential side effects of Zyrtec can include drowsiness, dry mouth, headache, and dizziness.
If you are experiencing severe hives that are not responding to the usual dosage of Zyrtec, it's essential to consult with a healthcare professional. They can assess your condition, determine the appropriate treatment, and recommend any adjustments to your medication regimen if necessary.
Remember that self-medicating or adjusting medication dosages without medical supervision can be risky, so it's best to seek professional advice for your specific situation. If you are experiencing any severe symptoms or difficulty breathing due to hives, seek immediate medical attention.
