It is crucial to remember that an overdose can be a medical emergency, and immediate medical attention is essential. In case of any accidental or intentional overdose, contacting emergency services or seeking medical help without delay is crucial for proper evaluation and management.

Missed Doses

If you miss a dose of Zyrtec, here are some general guidelines to follow:

1. Take it as soon as you remember: If you remember that you missed a dose and it is still within a reasonable timeframe of when you were supposed to take it, take the missed dose as soon as possible.
2. Skip the missed dose if it's close to the next scheduled dose: If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for the missed one.
3. Do not take extra doses: Avoid taking extra doses of Zyrtec to compensate for the missed dose. Taking more than the recommended dosage can increase the risk of side effects.
4. Resume regular dosing: After taking the missed dose or skipping it, continue taking Zyrtec as prescribed or according to the instructions on the product label.
