Why this happens
Vitamin C can change the chemical state of copper in the digestive tract, making it harder for the body to take it into the bloodstream. High levels of vitamin C may also compete with copper for transport into cells.

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.
