See the DrugPatentWatch profile for Meclizine
Meclizine is available under several brand names, with Bonine and Antivert being two of the most common [1][2]. Other brand names for meclizine include Dramamine Less Drowsy, Medivert, Motion Aid, and Re-Meni [3].
What conditions does meclizine treat?
Meclizine is primarily used to treat and prevent nausea, vomiting, and dizziness associated with motion sickness [1][2]. It is also prescribed to manage symptoms of vertigo, which can be caused by inner ear problems such as Meniere's disease [1][2].
How does meclizine work?
Meclizine is an antihistamine that functions by blocking the action of histamine in the brain. Histamine is a chemical that plays a role in triggering nausea and vomiting. By inhibiting histamine's effects on the vestibular system (the part of the inner ear responsible for balance) and the vomiting center in the brain, meclizine helps to alleviate symptoms of motion sickness and vertigo [4].
What are the differences between meclizine brands?
While meclizine is the active ingredient across these brands, there can be minor differences in formulation, inactive ingredients, or dosage strengths offered. For instance, Dramamine Less Drowsy specifically markets its reduced sedative effect compared to original Dramamine, although both contain different active ingredients (meclizine vs. dimenhydrinate) [5]. Bonine and Antivert are generally considered equivalent in their meclizine content and therapeutic effect for the same indications [1][2].
When did meclizine first become available?
Meclizine was first approved by the U.S. Food and Drug Administration (FDA) in the 1950s [6].
Are there generic options for meclizine?
Yes, generic versions of meclizine are widely available, offering a more affordable alternative to brand-name products [7].
What are the potential side effects of meclizine?
Common side effects of meclizine can include drowsiness, dry mouth, blurred vision, and fatigue [1]. Less common side effects may involve headache, nervousness, or vomiting [1]. It is important to consult a healthcare professional for a complete list of potential side effects and to discuss any concerns.
Can meclizine be taken by children?
Meclizine is generally not recommended for children under 12 years of age for motion sickness, though specific pediatric formulations or doctor recommendations may exist [1]. Always consult a pediatrician before administering meclizine to a child.
What are the drug interactions with meclizine?
Meclizine can interact with other medications, particularly those that cause drowsiness, such as sedatives, tranquilizers, and certain pain relievers [4]. It may also interact with anticholinergic drugs [4]. It is crucial to inform a doctor or pharmacist about all medications, supplements, and herbal products being taken before starting meclizine.
What is the typical dosage for meclizine?
For motion sickness, a typical adult dose is 25 mg to 50 mg taken one hour before travel [1]. For vertigo, dosages can vary and are determined by a physician [1].
