🍽️ cyclizine hydrochloride,(prescription)

Motion Sickness: Cyclizine hydrochloride is commonly used for the prevention and treatment of motion sickness, a condition characterized by nausea, vomiting, and dizziness experienced during travel, particularly in vehicles such as cars, airplanes, boats, or trains. By blocking histamine receptors in the brain and inner ear, cyclizine hydrochloride helps alleviate motion sickness symptoms and prevent their onset.

Nausea and Vomiting: Cyclizine hydrochloride is also used to relieve nausea and vomiting associated with various medical conditions, including viral gastroenteritis (stomach flu), inner ear disorders (such as labyrinthitis or vestibular neuritis), migraines, chemotherapy, and postoperative nausea and vomiting (PONV). It works by inhibiting the stimulation of the vomiting center in the brain and reducing the sensitivity of the inner ear to motion-induced nausea.

Vertigo: Cyclizine hydrochloride may be prescribed for the management of vertigo, a sensation of spinning or dizziness often caused by inner ear problems such as benign paroxysmal positional vertigo (BPPV), Meniere's disease, or vestibular migraine. By exerting antihistaminic and anticholinergic effects, cyclizine hydrochloride helps alleviate vertigo symptoms and improve balance and stability in affected individuals.

Dosage and Administration: Cyclizine hydrochloride is typically administered orally in the form of tablets or syrup. The dosage and frequency of administration depend on factors such as the severity of nausea or vomiting, the individual patient's response to treatment, and any underlying medical conditions. It is usually taken before travel or as needed to relieve symptoms. Cyclizine hydrochloride may also be administered intravenously (IV) in certain clinical settings, such as PONV prophylaxis in surgical patients.

Side Effects: Common side effects of cyclizine hydrochloride may include drowsiness, dizziness, dry mouth, blurred vision, constipation, and urinary retention. Less commonly, it may cause anticholinergic effects such as tachycardia (rapid heart rate), palpitations, confusion, and hallucinations. Rare but serious side effects may include allergic reactions, cardiac arrhythmias, and extrapyramidal symptoms (such as dystonia or tremor). Patients should be monitored for side effects during cyclizine hydrochloride therapy, and treatment should be adjusted or discontinued if adverse reactions occur.

Contraindications and Precautions: Cyclizine hydrochloride should be used with caution in patients with certain medical conditions, including glaucoma, urinary retention, prostatic hypertrophy, epilepsy, liver disease, and cardiovascular disorders. It is contraindicated in individuals with hypersensitivity to cyclizine hydrochloride or related compounds. Cyclizine hydrochloride may also interact with other medications, particularly central nervous system depressants, anticholinergic drugs, and monoamine oxidase inhibitors (MAOIs), increasing the risk of adverse effects or drug interactions.
