Why this happens
Both substances can affect the central nervous system. Melatonin is a hormone that regulates sleep-wake cycles, while lion's mane is a mushroom that may have calming effects on the brain. When used together, their sedative effects can add up (an additive effect).

Can I take Sertraline and Fluoxetine together?
Taking sertraline and fluoxetine together significantly increases the risk of a rare but serious condition called serotonin syndrome. This happens because both medicines work by increasing the level of a chemical called serotonin in your brain. If levels get too high, it can cause symptoms like shivering, diarrhoea, confusion, severe muscle tightness, fever, and even seizures.
