METHERGIN INJ

Methylergometrin, also known as methylergonovine, primarily acts as an agonist at specific serotonin receptors, mainly 5-HT2A and 5-HT2B subtypes, which are predominantly found in the smooth muscle fibers of the uterus. By stimulating these receptors, methylergometrin causes rapid and direct contraction of the uterine smooth muscle, leading to the constriction of blood vessels and reduced postpartum bleeding. This mechanism of action is particularly useful in the management of postpartum hemorrhage, as it aids in the rapid involution of the uterus and the control of bleeding.

Following are the conditions when Methylergometrin 0.2mg injection should not be administered:

• Allergic reactions Should not be used if the patient has a known allergy or hypersensitivity to methylergometrine or other ergot alkaloids.
• Pregnancy Contraindicated in pregnant women, especially during the first trimester, as it may restrict blood flow to the uterus and affect fetal development.
• Postpartum hypertension Should not be used in women with high blood pressure after childbirth, as it may increase blood pressure further.
• Migraine or vascular disease Not recommended for individuals with a history of severe migraine, heart disease, or blood vessel disorders.
• Liver or kidney impairment Methylergometrin should be avoided in patients with liver or kidney problems as it is primarily metabolized in the liver and excreted by the kidneys.
• Epilepsy Not suitable for patients with a history of seizures or epilepsy.
• Infections Should not be administered in cases of severe infections, as it may mask the symptoms and delay appropriate treatment.
• Thrombosis or embolism Contraindicated in individuals with a history of blood clots or embolisms, as it can increase the risk of these conditions.
• Raynaud's disease Should not be used in patients with Raynaud's disease, as it can worsen the symptoms.

The side effects of Methylergometrin 0.2mg injection may include:

• Nausea and vomiting
• Abdominal pain
• Headache
• Dizziness or lightheadedness
• High blood pressure (hypertension)
• Slow or irregular heartbeat
• Chest pain
• Allergic reactions (skin rash, itching, difficulty breathing)

Following are the precautions and warnings for Methylergometrin 0.2mg injection:

• Methylergometrin should be used with caution in patients with hypertension, as it may cause a sudden increase in blood pressure.
• Patients with a history of cardiovascular disease should be closely monitored, as this medication can affect heart rate and rhythm.
• It is important to avoid prolonged use, as it may lead to fibrosis and necrosis at the injection site.
• Methylergometrin should not be used during pregnancy, especially in the first trimester, as it can cause uterine contractions and harm the fetus.
• Breastfeeding women should exercise caution, as the drug may pass into breast milk and affect the infant.
• This medication should not be used in patients with severe liver or kidney disease without careful monitoring.
• Methylergometrin can cause severe headaches and migraines; patients with a history of migraines should use it with caution.
• Do not use this injection if there is any sign of infection or thrombosis at the injection site.

Following are the drug interactions for Methylergometrin 0.2mg injection:

• It should not be used with other ergot alkaloids due to the risk of additive vasospasm and ergotism.
• The effects of Methylergometrin may be reduced by drugs like bromocriptine and cabergoline, which are dopamine agonists.
• Antihypertensive medications may have their blood pressure-lowering effects diminished by Methylergometrin.
• Caution is advised when using Methylergometrin with drugs that prolong QT interval, as it may increase the risk of arrhythmias.
• The vasoconstrictive effects of Methylergometrin can be increased by sympathomimetic agents, leading to hypertension.
• The absorption of Methylergometrin may be decreased by antacids containing aluminum hydroxide or magnesium hydroxide.
• Methylergometrin can interact with general anesthetics, increasing the risk of hypertension and vasoconstriction during surgery.

Following are the food interactions for Methylergometrin 0.2mg injection:

• Avoid excessive consumption of caffeine-rich foods and beverages like coffee, tea, and energy drinks as they may increase blood pressure and heart rate, especially when combined with Methylergometrin.
• Grapefruit and grapefruit juice should be consumed with caution as they can inhibit the breakdown of Methylergometrin, leading to increased drug levels in the body and potential side effects.
• Alcohol should be avoided as it may lower blood pressure, and when combined with Methylergometrin, it can cause a sudden drop in blood pressure, leading to dizziness or lightheadedness.
• High-fiber foods like whole grains, legumes, and certain vegetables may affect the absorption of Methylergometrin. It is advisable to maintain a consistent diet during the course of medication.
• Avoid tyramine-rich foods such as aged cheeses, cured meats, and certain fermented foods. Tyramine can interact with Methylergometrin, leading to a sudden increase in blood pressure.
• Limit the intake of salt and high-sodium foods as they may counteract the effects of Methylergometrin on blood pressure regulation.
• Always ensure you are well-hydrated when taking Methylergometrin, especially if you have a diet rich in potassium-rich foods like bananas, oranges, and leafy greens.
• Consult your healthcare provider for personalized dietary advice, especially if you have specific dietary restrictions or medical conditions.
