Metamizole sodium hydrate is widely used as a potent analgesic and antipyretic in medical settings. It is particularly effective in managing moderate to severe pain, such as post-operative pain, cancer-related pain, and acute conditions like migraines or renal colic. Its strong pain-relieving properties make it a preferred choice in cases where other analgesics like NSAIDs or opioids are less effective or contraindicated. Additionally, it is used to reduce high fever when other antipyretics fail to provide adequate relief. In some countries, it is administered intravenously or intramuscularly in hospital settings for rapid pain relief. However, its use is restricted or banned in certain regions due to potential risks of agranulocytosis, a rare but serious side effect. Despite this, it remains a valuable therapeutic option in many parts of the world under strict medical supervision.
