How does Menaril 16mg Tablet work?

Menaril 16mg Tablet works by increasing the blood flow to your brain and by lowering the extra pressure build up in the inner ear. By easing down the symptoms associated with Meniere's disease, this drug helps a person to live their normal life.

Side Effects of Menaril 16mg Tablet

• Nausea and vomiting
• Headache
• Indigestion
• Bloating
• Skin rash and itching
• Difficulty in breathing
• Abdominal pain

Quick Suggestions:

• Limit caffeine intake: Avoid or limit the consumption of caffeine-containing beverages like tea, soda, coffee, and energy drinks, as caffeine can stimulate the nervous system and potentially worsen tinnitus.
• Maintain regular eating patterns: Do not stay without eating for more than 4 hours. Consistently spacing out meals throughout the day can help stabilize blood sugar levels and potentially reduce symptoms.
• Limit alcohol consumption: Alcohol intake should be limited, as it may decrease the chances of experiencing migraines, which can be associated with Meniere's disease.
• Get sufficient sleep: Aim for 8 hours of quality sleep per night, as proper sleep helps the body relax and may contribute to better overall well-being.
• Quit smoking: Tobacco and smoking can narrow blood vessels and affect circulation, which may have a negative impact on Meniere's disease symptoms. Quitting smoking is beneficial for your overall health.
• Follow the prescribed medication regimen: Take Menaril 16mg Tablet exactly as prescribed by your doctor, following the recommended dose and duration. Consistency in taking the medication is important for optimal effectiveness.
• Consult with your doctor: Before starting Menaril or any other medication, consult with your doctor, especially if you have any medical conditions, are pregnant or breastfeeding, or are taking other medications. Your doctor can provide personalized guidance based on your specific situation.
• Allergies and discontinuation: Inform your doctor if you are allergic to betahistine or any other ingredients in Menaril tablets. Do not abruptly stop taking Menaril without consulting your doctor, as this may worsen your symptoms.
• Common side effects: Some common side effects of Menaril tablets may include stomach pain, indigestion, and nausea. If these side effects persist or become bothersome, inform your doctor.
• Low sodium diet: Consider consuming low sodium-containing foods, as excessive sodium intake may contribute to fluid retention and potentially worsen symptoms related to the inner ear.

Indication

An anti-vertigo drug, Menaril 16mg Tablet treats Meniere’s disease (signs including dizziness, vertigo, tinnitus, nausea, and hearing problems)

Pharmacology

Betahistine has a complex mode of action that involves multiple mechanisms:

• Agonism at histamine H1 receptors: Betahistine acts as an agonist at histamine H1 receptors in the inner ear. This stimulation leads to vasodilation of blood vessels, increased permeability, and a reduction in endolymphatic pressure. By maintaining the equilibrium of endolymphatic fluid, betahistine helps prevent the rupture of the labyrinth, which can contribute to hearing loss associated with Ménière's disease.
• Stimulation of vestibulocochlear blood flow: Betahistine's activation of H1 receptors in the inner ear also enhances blood flow to the vestibulocochlear system. This increased blood flow is thought to contribute to the alleviation of vertigo symptoms.
• Antagonism at histamine H3 receptors: Betahistine acts as an antagonist at histamine H3 receptors. By blocking these receptors, betahistine increases the turnover of histamine from postsynaptic histaminergic nerve receptors. This, in turn, enhances the activity of histamine at H1 receptors. The increased histamine activity, particularly in the brainstem, leads to elevated levels of neurotransmitters such as serotonin. The inhibition of vestibular nuclei activity by serotonin helps restore normal balance and reduces symptoms of vertigo.

Interaction

Menaril 16mg Tablet can interact with several medications, including:

• Isocarboxazid: It is an MAO inhibitor, and combining it with Menaril may increase the risk of side effects such as increased blood pressure, headache, or serotonin syndrome.
• Cetirizine and Chlorpheniramine: These are other antihistamines, and taking them together with Menaril may enhance the sedative effects of both medications.
• Salmeterol and Formoterol: These are beta-2 agonists commonly used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Combining them with Menaril may increase the risk of cardiovascular side effects such as increased heart rate or irregular heartbeat.
• Regarding drug-food interactions, no specific interactions have been reported for Menaril 16mg Tablet. However, it is generally advised to limit alcohol, caffeine, and high-salt diet consumption as they may worsen the symptoms of certain conditions, including Meniere's disease.

It's important to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs and herbal supplements, to avoid potential interactions. They will be able to assess the risks and benefits and provide appropriate guidance for your specific situation.

Contraindications

Betahistine is not recommended for use in patients with pheochromocytoma or porphyria. Pheochromocytoma is a rare tumor of the adrenal gland that can cause excessive release of adrenaline and noradrenaline, and betahistine can potentially increase the release of these substances, leading to worsening symptoms. Porphyria is a group of rare genetic disorders that affect the production of heme, a component of hemoglobin, and certain medications, including betahistine, may trigger porphyria attacks in susceptible individuals. It's important to inform your healthcare provider about any existing medical conditions, including pheochromocytoma or porphyria, before starting any new medications. They will be able to determine the appropriate treatment options for your specific situation.

Pregnancy & Lactation

In Pregnancy: Although there is no known teratogenic impact in animals, the safety of Betahistine in human pregnancy has not been fully proven. Before administering Betahistine during pregnancy, it's important to weigh the potential advantages carefully.

Lactation: Betahistine is excreted in similar amounts in the breast milk of nursing mothers as it is in the plasma. The neonate's toxicity at these amounts is unknown.

Precautions & Warnings

• Porphyria: Menaril 16mg Tablet is not recommended for use in patients with porphyria. Porphyria is a group of rare genetic disorders that affect the production of heme, a component of hemoglobin. The use of betahistine in patients with porphyria may exacerbate the condition.
• Bronchial asthma: Menaril 16mg Tablet should be used with caution in patients with bronchial asthma. This caution is advised due to the potential for betahistine to cause bronchospasm or narrowing of the airways in susceptible individuals with asthma.
• Galactose intolerance: Menaril 16mg Tablet is not recommended for use in individuals with galactose intolerance. Galactose intolerance is a rare genetic disorder where the body is unable to metabolize galactose, a sugar found in lactose-containing foods. Since the tablet may contain lactose, it is important to avoid its use in individuals with galactose intolerance.
• Vertigo, tinnitus, and hearing loss: Menaril 16mg Tablet is commonly used to manage symptoms associated with Ménière's syndrome, including vertigo, tinnitus, and hearing loss. These symptoms can significantly impact a person's ability to drive or operate machinery. It is important to be aware of the potential effects of these symptoms on your ability to perform such activities and exercise caution accordingly.
• Stomach discomfort: Menaril 16mg Tablet may cause mild stomach discomfort as a side effect. Taking the medication with food can help reduce stomach problems. It is advisable to follow the prescribed instructions regarding the timing of the medication with respect to meals.
• Pregnancy and lactation: Pregnant or breastfeeding females should consult with their doctor before taking Menaril 16mg Tablet. The use of this medication during pregnancy or lactation should be evaluated carefully, weighing the potential benefits against any potential risks to the mother and the developing baby.
• Active peptic ulcer: Menaril 16mg Tablet is contraindicated in individuals with an active peptic ulcer. The medication may exacerbate the ulcer or delay its healing.
