Doctor Explains Cetirizine Dosage, Drowsiness and Rare Withdrawal
Cetirizine is a medicine that can help with allergies.
A doctor says people generally take it once a day, as recommended.
Taking extra tablets again and again can make side effects more likely.
The medicine can make some people sleepy or tired.
It can also cause problems such as dizziness or a dry mouth.
Older people and those with kidney problems should be especially careful.
Other medicines that cause sleepiness can make this effect stronger.
A few people who have taken cetirizine every day for a long time may get very itchy after they stop.
If symptoms continue or unusual effects occur, ask a doctor instead of taking more on your own.
Cetirizine is generally taken once daily at the recommended dose; taking extra doses repeatedly can raise the risk of side effects.
Common side effects include drowsiness or fatigue, and may also include dry mouth, headache, dizziness or gastrointestinal symptoms.
Older adults and people with reduced kidney function should use particular caution because the medicine is mainly cleared through the kidneys.
Other medicines that cause drowsiness may add to cetirizine’s sedating effects, so drivers and machinery operators should monitor their alertness.
After prolonged daily use, a small number of people may develop intense itching within days of stopping; persistent allergy symptoms may require another treatment approach.
