Cyclizine Wikipedia

Theaters warned patrons of its possible nauseating effects, cautioning pregnant women in particular. Blair Witch was filmed with a handheld camcorder, which was subjected to considerably more motion than the average movie camera,19 and lacks the stabilization mechanisms of steadicams. For the sake of novelty, IMAX and other panoramic type theaters often show dramatic motions such as flying over a landscape or riding a roller coaster. The sensory conflict theory notes that the eyes view motion while riding in the moving vehicle while other body sensors sense stillness, creating conflict between the eyes and inner ear.

Tell your healthcare provider about all of your health conditions and any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. This will help them determine if meclizine is right for you. Through its antagonistic action on the H1 receptors, meclizine primarily works by inhibiting signaling pathway transduction through histaminergic neurotransmission from the vestibular nuclei and NTS to the CTZ and medullary vomiting center. Meclizine may also decrease the labyrinth excitability and vestibular stimulation.

Motion sickness

This may not be a complete list of medicines that can interact with meclizine. Do not share meclizine that was prescribed for you by a healthcare provider with other people, even if they have the same condition as you. Other drugs may interact with meclizine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all other medicines you use. Phenergan (promethazine) is used to treat allergy symptoms and prevent motion sickness.

Meclizine Alcohol interaction

Tell your healthcare provider if you have any of the following. Keep a written list of all of the prescription and nonprescription (over-the-counter) medicines, vitamins, minerals, and dietary supplements you are taking. Bring this list with you each time you visit a doctor or if you are admitted to the hospital. You should carry the list with you in case of emergencies.

Meclizine is a commonly prescribed drug by many healthcare professionals, including primary care providers, emergency medicine physicians, oncologists, internists, and advanced practice practitioners. When prescribing this medication, all healthcare practitioners should be aware of the common adverse reactions of the drug and the most susceptible population. The successful use of the drug also depends on the patient’s adherence to and knowledge of the potential effects of the drug. Vomiting is a centrally regulated reflex mechanism that initiates from the vomiting center and the chemoreceptor trigger zone (CTZ) located in the medulla. The blood-brain barrier near the CTZ is relatively permeable to circulating mediators and CTZ can transmit impulses to vomiting center located in the brainstem. Different receptors responding to different factors, including histamine, 5-HT, enkephalins, substance P, and dopamine, are expressed along the brainstem to activate respective pathways and contribute to the control of vomiting.

• If you are on a dosing schedule, skip any missed dose.
• Sometimes it is not safe to use certain medicines at the same time.
• Some other medicines may alter the blood levels of meclizine.

Hypotension may also occur, particularly in the elderly. In children, anticholinergic effects and CNS stimulation, characterized by hallucinations, seizures, trouble sleeping, are more likely to occur. In case of overdose, symptomatic and supportive treatment is recommended. In case of recent ingestion, induction of emesis or gastric lavage should be initiated to limit further drug absorption. Although there is no known antidote to meclizine, physostigmine may be useful to counteract the CNS anticholinergic effects of meclizine. Additionally, this medication proves beneficial in off-label applications, extending its utility to address analogous symptoms triggered by viral illnesses, gastrointestinal infections, pregnancy, or radiation therapy.

Adverse Reactions

It is not known if meclizine wikipedia or how meclizine could affect pregnancy or harm an unborn baby. Tell your healthcare provider if you are or plan to become pregnant.

Meclizine may cause allergic reactions, which can be serious.

It is most effective if taken before symptoms appear. Meclizine is used in adults and children aged 12 years and older to treat or prevent nausea, vomiting and dizziness caused by motion sickness. Poor visibility conditions, such as fog, may worsen seasickness.

It also exerts a depressive action against the nervous system and an anesthetizing effect locally. Finally, it reduces the excitability of the labyrinth and vestibular stimulation and may influence the activity of receptors that trigger vomiting. People aged 65 years or older can be at greater risk for some side effects of meclizine. Talk to your healthcare provider about your risks if you are in this age group. Sometimes it is not safe to use certain medicines at the same time.

Cinnarizine

It is proposed that meclizine may be excreted into breast milk. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol. In addition, the potential for abuse may be increased with the combination. Meclizine may increase the toxicity with CNS depressants, neuroleptics and anticholinergic. Alcohol, sedatives and tranquilizers can increase the drowsiness of the patient. The oral and intraperitoneal LD50 in mouse are 1600 mg/kg and 625 mg/kg, respectively.
