How It Works
Cetirizine is a second-generation antihistamine that works by blocking histamine H1 receptors in the body. Histamine is a natural chemical released during an allergic reaction that causes symptoms such as itching, sneezing, a runny nose, and watery eyes. By blocking histamine, cetirizine helps to reduce and relieve these uncomfortable symptoms. It is considered a non-drowsy antihistamine, although some people may still feel mildly sleepy.

Interactions
Cetirizine is not known to interact with many medicines, but caution should be taken when combined with medicines that cause sedation, such as sleeping tablets, anxiety medicines, or strong painkillers, as drowsiness may be increased. Theophylline (used for breathing conditions) may slightly reduce how quickly cetirizine is cleared from the body. Tell your PillSorted pharmacist or doctor about all medicines you are currently taking, including herbal remedies and supplements.
⸻
Pregnancy and Breastfeeding
The safety of cetirizine during pregnancy has not been fully established, and it is generally not recommended unless considered essential by a doctor. Cetirizine passes into breast milk and should be avoided during breastfeeding unless your doctor advises otherwise. Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.
⸻
Alcohol
You should avoid drinking alcohol whilst taking cetirizine. Alcohol can increase the risk of drowsiness and dizziness associated with cetirizine, which may affect your ability to carry out everyday tasks safely.
⸻
Driving and Operating Machinery
Although cetirizine is classed as a non-drowsy antihistamine, some people may still experience drowsiness, dizziness, or blurred vision. You should not drive or operate heavy machinery until you know how this medicine affects you. If you feel drowsy after taking it, do not drive or perform tasks that require full alertness.
