Crampster Tablet contains Vitamin E (10mg) + L-Carnitine L-Tartrate (200mg) + Magnesium Aspartate (250mg) + Magnesium Chloride (150mg). It belongs to the Mineral supplement (magnesium salts) + antioxidant (vitamin E) + metabolic agent (L-carnitine) class of medicines.
Magnesium (as aspartate and chloride) replenishes body magnesium stores and supports normal neuromuscular transmission, which may reduce muscle cramps due to deficiency. L-carnitine supports transport of fatty acids into mitochondria for energy production, helping reduce fatigue. Vitamin E acts as an antioxidant, helping protect cells from oxidative stress.
Tablet for oral use. Take as directed by the physician; commonly taken once daily after food with water. Do not exceed the recommended dose; if stomach upset occurs, take with meals.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take the missed dose of Crampster as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.
Taking more Crampster than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.
Most side effects of Crampster are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Not for treatment of acute severe cramps without medical evaluation. Use with caution in kidney disease or reduced urine output due to risk of magnesium accumulation (may cause weakness, low blood pressure, slow heartbeat). Consult a doctor if pregnant/breastfeeding, if you have heart rhythm disorders, myasthenia gravis, or persistent diarrhea. Stop and seek medical advice if rash, severe diarrhea, or signs of high magnesium (severe weakness, confusion, breathing difficulty) occur.
Tetracyclines (e.g., doxycycline), quinolones (e.g., ciprofloxacin/levofloxacin), bisphosphonates (e.g., alendronate), levothyroxine—magnesium can reduce absorption; separate by 2–4 hours. Diuretics (loop/thiazide), PPIs—may affect magnesium levels. CNS depressants or antihypertensives—high magnesium may enhance hypotension/sedation in rare cases.
Store below 25°C in a cool, dry place. Protect from moisture and direct light. Keep out of reach of children.
