What are the side effects of Lemborexant?

Lemborexant is a medication commonly prescribed for the treatment of insomnia, particularly in adults. It belongs to a class of drugs known as orexin receptor antagonists, which work by modulating the activity of chemicals in the brain that regulate the sleep-wake cycle. While Lemborexant can be effective in improving sleep patterns, it is essential for patients and healthcare providers to be aware of the potential side effects associated with its use.

The most frequently reported side effects of Lemborexant include drowsiness and fatigue. Because this medication is designed to promote sleep, it is not surprising that some users may experience these effects, particularly if they do not get a full night's sleep or if they take the medication at a higher dose than prescribed. It is crucial to follow the dosing instructions provided by a healthcare provider to minimize the risk of excessive drowsiness.

Another common side effect is headache. While not everyone will experience this, headaches can occur as the body adjusts to the medication. If headaches persist or become severe, it is important to consult a healthcare provider for advice.

Some patients may experience dizziness or a feeling of unsteadiness. This can be particularly concerning for older adults or those with mobility issues, as it can increase the risk of falls and related injuries. To reduce the likelihood of dizziness, it is advised to avoid activities that require full alertness, such as driving or operating heavy machinery, especially when first starting the medication or adjusting the dosage.

Lemborexant may also cause abnormal dreams or nightmares. While this side effect is less common, it can be distressing for some individuals. If abnormal dreams become bothersome or impact the quality of sleep, discussing this with a healthcare provider can help determine whether an adjustment in dosage or a change in medication is needed.

There is also the potential for more serious side effects, although these are rare. Some individuals may experience complex sleep behaviors, such as sleepwalking, sleep-driving, or engaging in other activities while not fully awake. These behaviors can be dangerous and require immediate medical attention. If a patient experiences any unusual sleep behaviors, they should stop taking Lemborexant and contact their healthcare provider right away.

Allergic reactions to Lemborexant are uncommon but possible. Symptoms of an allergic reaction may include rash, itching, swelling, severe dizziness, or difficulty breathing. Any signs of an allergic reaction should be treated as a medical emergency, and immediate medical help should be sought.

In summary, while Lemborexant can be an effective treatment for insomnia, it is important to be aware of the potential side effects. Common side effects include drowsiness, fatigue, headache, dizziness, and abnormal dreams, while more serious side effects, such as complex sleep behaviors and allergic reactions, are less common but require prompt medical attention. Patients are encouraged to communicate openly with their healthcare providers about any side effects they experience to ensure safe and effective use of Lemborexant.
