Meclizine

Product Description

Meclozine is an antihistamine with additional anticholinergic properties, widely used for its ability to relieve symptoms such as dizziness, nausea, and vomiting. Although its exact mechanism of action in vestibular disorders remains not fully defined, studies suggest that it acts on the peripheral structures of the inner ear, particularly the labyrinth—where receptors for balance and hearing are located. By modulating signals within these structures, Meclozine helps restore equilibrium and reduce motion-induced symptoms. Its long-lasting effects make it especially effective in managing motion sickness and inner ear-related imbalances.

Safety Information

Meclozine is primarily used for the prevention and symptomatic relief of nausea, dizziness, and vomiting, rather than addressing their root causes. It is especially useful for motion sickness and vestibular conditions, as well as for managing symptoms during pregnancy or in cases of inner ear dysfunction. While generally well tolerated, it should be used under medical supervision in patients with certain underlying conditions. Caution is advised when driving or operating machinery, as the medication may cause drowsiness in some individuals.

Mode of Application

For adults and children over 12 years old, Meclozine is typically prescribed at a daily dose of 25 to 100 mg, divided into multiple doses depending on the severity of symptoms and therapeutic response. A single 25 to 50 mg dose can effectively prevent motion sickness symptoms for up to 24 hours and should be taken at least one hour before travel. In cases of vestibular or labyrinthine disorders, the daily dose is also adjusted within the 25 to 100 mg range, tailored to the individual’s clinical needs. During pregnancy, Meclozine may be used at doses of 25 to 50 mg daily to alleviate nausea and vomiting, though it should always be taken under the guidance of a healthcare provider.

Contraindications

Meclozine is contraindicated in individuals with known hypersensitivity to the medication. Patients with glaucoma or enlarged prostate should only use Meclozine if specifically prescribed by a physician, due to potential exacerbation of symptoms. Although extensive experience with Meclozine in pregnant women has not shown teratogenic effects, it is still recommended to evaluate the risks and benefits before initiating treatment. Because of the potential for drowsiness, it is important to exercise caution when engaging in activities that require full alertness.

Side Effects

Meclozine is generally well tolerated, but some users may experience drowsiness, dry mouth, or fatigue. In rare cases, side effects such as vomiting or blurred vision may occur, particularly with higher doses. Like other antihistamines, Meclozine can occasionally cause increased excitability in children. Most side effects are mild and transient, but patients are advised to monitor their reactions and consult a healthcare professional if symptoms persist or worsen.
