Why this happens
Iron supplements and fluoxetine are processed by the body through different pathways. Iron is absorbed in the digestive tract, while fluoxetine is metabolised primarily by the liver. They do not interfere with each other's absorption or effectiveness.
What you should do
You can safely take these together. To minimise potential stomach upset, you may wish to take your iron supplement with food (unless your doctor has told you to take it on an empty stomach for better absorption) and take your Prozac at a different time of day. If you experience significant nausea or constipation, speak with your pharmacist.
