In reported cases of overdoses with dexamethasone, adverse effects included seizures, gastrointestinal perforation, and heart attack. Long-term use can also cause Cushing's syndrome, osteoporosis, and cataracts, among other things. Treatment typically involves monitoring and relieving any problems that occur as a result of the overdose.
Can You Take Too Much Dexamethasone?Dexamethasone is a prescription corticosteroid, or "steroid," medication. It decreases inflammation and suppresses the body's immune system. As with most medications, it is possible to take too much dexamethasone.
A dexamethasone overdose is usually not extremely dangerous. However, the specific effects would likely vary, depending on a number of factors, including the dexamethasone dosage, the particular form of the medication taken, and whether it was taken with any other medications or substances.
