Why this happens

Iron supplements and pregabalin are processed by the body through different pathways. Iron is absorbed in the small intestine and does not affect the transport systems or enzymes that pregabalin uses. Pregabalin is not metabolised by the liver and is excreted unchanged by the kidneys, meaning it does not compete with iron for clearance.

You can take iron supplements and pregabalin together. You do not need to space them apart or change the timing of your doses. However, always follow the specific instructions provided by your doctor or pharmacist regarding whether to take your iron on an empty stomach or with food, as this can affect iron absorption.

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.

Pregnancy

Pregnancy must be avoided. Pregabalin use during the first trimester is linked to an increased risk of major physical birth defects in the baby.

Suicidal thoughts and behaviours

Seek immediate medical help if you experience any changes in mood, distressing thoughts, or feelings of self-harm, as pregabalin can increase the risk of suicidal ideation.

Respiratory depression

Pregabalin can cause severe breathing problems, especially if you already have lung disease or if you take it with other medicines that cause drowsiness or contain opioids.

Drug dependence and misuse

Pregabalin can lead to dependence and addiction. Only take the dose prescribed and do not stop taking it suddenly, as this can cause severe withdrawal symptoms.

Alcohol

It is best to avoid or strictly limit alcohol while taking pregabalin. Both substances affect the central nervous system; combining them increases the risk of severe drowsiness, dizziness, and breathing difficulties.

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.

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.
