Intro
Levocetirizine is a popular antihistamine medication used to treat allergies, itching, and hives. It is a stereoisomer of cetirizine, which means it has a similar molecular structure but with a different arrangement of atoms. While levocetirizine is generally considered safe and effective, like all medications, it can cause side effects in some people. In this article, we will delve into the potential side effects of levocetirizine, their severity, and what you can do to minimize them.

Common Side Effects of Levocetirizine
The most common side effects of levocetirizine are mild and temporary. According to the FDA, the most frequently reported side effects include:
- Drowsiness or sedation
- Dry mouth
- Fatigue
- Headache
- Stomach upset or nausea
These side effects are usually mild and may go away on their own within a few days. However, if they persist or worsen, it is essential to consult your doctor.
Less Common Side Effects of Levocetirizine
In addition to the common side effects, levocetirizine can also cause less frequent but more severe side effects, including:
- Allergic reactions, such as anaphylaxis, angioedema, or urticaria
- Cardiac problems, such as changes in heart rate or blood pressure
- Confusion, disorientation, or hallucinations
- Increased risk of urinary retention or difficulty urinating
- Seizures or convulsions
If you experience any of these side effects, seek medical attention immediately.

Long-Term Side Effects of Levocetirizine
While levocetirizine is generally considered safe for short-term use, long-term use can increase the risk of certain side effects. These include:
- Rebound congestion, which can occur when the body becomes accustomed to the medication and the nasal passages become dependent on it

It is essential to discuss the potential risks and benefits of long-term levocetirizine use with your doctor.
Levocetirizine Interactions with Other Medications
Levocetirizine can interact with other medications, including:

It is crucial to inform your doctor about all medications, supplements, or herbal products you are taking before starting levocetirizine.
