What side effects are linked to levocetirizine dihydrochloride tablets?
Levocetirizine dihydrochloride (an antihistamine used for allergy symptoms) can cause typical “antihistamine” side effects. Commonly reported effects include sleepiness or drowsiness, fatigue, dry mouth, and dizziness. [1]
What are the more serious side effects to watch for?
Serious reactions are uncommon, but seek urgent medical care if you get signs of allergy to the medication, such as swelling of the face/lips/tongue, trouble breathing, or widespread rash. [1]
If you experience severe dizziness, fainting, or unusual behavior or confusion, contact a clinician promptly. [1]
Can levocetirizine make you drowsy or affect driving?
Yes. Drowsiness is one of the more important cautions with levocetirizine. If you feel sleepy after taking it, avoid driving or operating machinery until you know how it affects you. [1]
Who is more likely to get side effects?
Side effects can be more likely in people who are sensitive to antihistamines, and in those taking other medicines that cause drowsiness (because effects can add up). Kidney problems may also increase the chance of experiencing side effects, since levocetirizine is cleared by the kidneys. [1]
What should you do if you miss a dose or take too much?
If you miss a dose, take it when you remember unless it’s close to the next dose; don’t take double doses. Taking more than prescribed can increase the risk of side effects such as strong drowsiness or other adverse effects, so follow dosing instructions and contact a clinician or poison control for guidance if an overdose is suspected. [1]
Does levocetirizine have fewer side effects than older antihistamines?
Compared with some first-generation antihistamines, levocetirizine is generally less likely to cause strong sedation, but drowsiness can still occur. If you need an allergy medicine with minimal daytime effects, discuss options with a clinician or pharmacist based on your symptoms and other medications. [1]
Are there drug interactions that increase side-effect risk?
Medicines that also make you sleepy (such as certain cold medicines, sedatives, or sleep aids) can increase drowsiness when taken with levocetirizine. Tell your pharmacist or prescriber about all medicines and supplements you use so they can check for interactions. [1]
