What should you do if you use too much cetirizine?


Call your doctor right away or seek immediate medical attention if your symptoms do not improve or they become worse after using cetirizine. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource if you think you’ve used too much cetirizine. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.


If you think it is an emergency, call 999 or find your nearest A&E
If you need help now, but it’s not an emergency go to 111.nhs.uk or call 111. Alternatively you can speak to one of our pharmacists or use the Now Patient app to make an appointment with your GP.

What should I do if I miss my dose?

There are occasions when people forget to take their medication at correct prescribed times. This may not only have an effect on potentially making the medication less effective but it may also inadvertently lead to taking doses too close together, thereby increasing the risks of side effects.
