Can I take Iron supplements and Prozac together?

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.

Important precautions

Suicidal thoughts and worsening of depression

When first starting Prozac or changing the dose, you may experience an increase in suicidal thoughts or self-harm. This is more common in young adults under 25. Seek immediate medical help if your mood worsens.

Increased risk of bleeding

Taking Prozac can increase your risk of bleeding, especially in the stomach. This risk is significantly higher if you also take anti-inflammatory painkillers like ibuprofen or aspirin.

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.

Bipolar disorder

Prozac can trigger a manic episode (periods of high energy, racing thoughts, and impulsive behaviour) if you have undiagnosed bipolar disorder.

Low sodium levels (hyponatremia)

Prozac can cause a serious drop in blood sodium levels, especially in older adults or those taking diuretics. Seek medical help if you experience severe confusion, weakness, or seizures.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking Prozac. Combining alcohol with this medication can increase drowsiness, dizziness, and impair your coordination. It can also make the symptoms of your underlying condition worse.

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.

Prozac can sometimes increase the effects of caffeine in your body. This may lead to feeling jittery, anxious, or having difficulty sleeping. If you notice these effects, you should reduce your caffeine intake.

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.
