Cetirizine is a widely used antihistamine for treating allergy symptoms like sneezing, runny nose, itchy eyes, and hives. Understanding the maximum daily dose is crucial for safe and effective use. This article provides a comprehensive overview of cetirizine dosage, potential side effects of exceeding the recommended amount, and what to do in case of an overdose.

Understanding Cetirizine Dosage

The maximum recommended dose of cetirizine varies depending on age and specific formulation. Always follow the instructions provided by your doctor or pharmacist and the information on the product label. Never exceed the recommended dosage without consulting a healthcare professional.

Adults (12 years and older):

The usual adult dose of cetirizine is 10 mg once daily. This is also generally considered the maximum daily dose. Taking more than 10mg in 24 hours isn't recommended and may increase the risk of side effects.

Children (6-12 years old):

For children aged 6 to 12 years, the typical dose is 5-10 mg once daily, depending on their weight and the doctor's recommendation. Again, exceeding the prescribed dose should be avoided.

Children under 6 years old:

Cetirizine is generally not recommended for children under 6 years old unless specifically prescribed by a pediatrician. The dosage and maximum daily dose for this age group will be determined based on individual needs and weight.

Potential Side Effects of Exceeding the Cetirizine Dose

Taking more cetirizine than recommended can lead to several side effects, ranging from mild to severe. These can include:

Drowsiness: This is a common side effect of cetirizine, and it's often amplified when taking a higher dose. Driving or operating machinery should be avoided if you experience drowsiness.
Dry mouth: Excessive dryness in the mouth is another frequent side effect.
Headache: Some individuals may experience headaches after taking a higher than recommended dose.
Fatigue: Increased tiredness and fatigue are also possible.
Dizziness: Feeling lightheaded or dizzy is another potential consequence.
Nausea: Stomach upset and nausea can occur.
In more severe cases: Overdosing on cetirizine can lead to more serious side effects such as seizures, rapid heart rate, and even hallucinations. These are rare but require immediate medical attention.

What to Do if You Take Too Much Cetirizine

If you accidentally take more cetirizine than recommended, contact your doctor, pharmacist, or a poison control center immediately. Don't attempt to self-treat. They can provide guidance based on your specific situation.

It is crucial to provide the following information when contacting medical professionals:

The amount of cetirizine you took.
When you took it.
Your age and weight.
Any other medications you're currently taking.
Any symptoms you are experiencing.
