There is no known direct interaction between iron supplements and Wellbutrin (bupropion). However, both substances can occasionally cause stomach-related side effects like nausea or constipation, which might be more noticeable if taken together.
Why this happens
Iron supplements and bupropion are processed by the body through different pathways. Iron is absorbed in the digestive tract and does not interfere with the liver enzymes that break down bupropion. Furthermore, they do not compete for the same receptors in the brain or body.
What you should do
You can safely take these together. To reduce the risk of an upset stomach, you may wish to take your iron supplement with food (unless your doctor has told you otherwise) and take your Wellbutrin at its usual scheduled time. If you experience significant constipation, ensure you drink plenty of water and speak to a pharmacist.
Important precautions
Seizure disorders or epilepsy
Bupropion significantly increases the risk of seizures. You must not take it if you have a history of epilepsy, an eating disorder (bulimia or anorexia), or if you are undergoing sudden withdrawal from alcohol or benzodiazepines.
Accidental overdose in children
Iron supplements are a leading cause of fatal poisoning in children. You must store this medicine in a secure place out of the reach and sight of children.
Eating disorders (Anorexia or Bulimia)
There is a much higher risk of having a seizure if you take Wellbutrin and have ever been diagnosed with an eating disorder.
Food and drink warnings
Alcohol
It is best to avoid or strictly limit alcohol while taking bupropion. Combining them can increase the risk of neurological side effects and, more seriously, may increase the risk of having a seizure. If you drink alcohol regularly, do not stop suddenly without talking to your doctor, as this can also trigger seizures.
It is best to avoid or strictly limit alcohol when taking iron supplements. Chronic alcohol consumption can interfere with how iron is stored and processed in the liver, potentially increasing the risk of iron toxicity or liver strain.
Tea, Coffee, and Caffeine
Caffeine and tannins found in tea and coffee significantly reduce the amount of iron your body absorbs. You should avoid drinking these for at least 2 hours before or after taking your iron supplement.
Bupropion and caffeine are both stimulants. Consuming high amounts of caffeine (coffee, tea, energy drinks) while taking this medicine can increase the risk of side effects like anxiety, tremors, rapid heartbeat, and insomnia.
Dairy products (Milk, Cheese, Yoghurt)
Calcium in dairy products prevents iron from being absorbed properly. Avoid consuming dairy for at least 2 hours before or after your dose.
Eggs and Whole Grains
Compounds in eggs (phosphoprotein) and whole grains (phytates) can interfere with iron absorption. It is best to take iron on an empty stomach, at least 1 hour before or 2 hours after meals.
Vitamin C (Orange Juice)
Taking your iron supplement with a glass of orange juice or foods rich in Vitamin C is beneficial, as it helps your body absorb the iron more effectively.

Can I take Mounjaro and Paracetamol together?
Mounjaro may slow down how quickly your body absorbs paracetamol. This means it might take longer for the paracetamol to start working to relieve pain or reduce a fever. However, the total amount of medicine that gets into your system should remain the same.
