Posso prendere Ferro e Levotiroxina insieme?

Ferro e levotiroxina should not be taken at the same time as taking them together can significantly reduce the amount of thyroid hormone your body absorbs.

Perché succede

Iron binds to levothyroxine in the stomach and intestines, forming a complex that is too large for the body to absorb into the bloodstream. This means the medicine passes through your system without working.

How to take iron and levothyroxine safely

• You should take these medicines at least 4 hours apart.

• Most people find it easiest to take their levothyroxine first thing in the morning (on an empty stomach) and wait until the afternoon or evening to take their iron supplement.

• Do not stop taking either medication without speaking to your doctor or pharmacist.

Precauzioni importanti

Accidental overdose in children

Iron supplements are a leading cause of fatal poisoning in children. Keep them strictly out of reach and sight of children; even a small number of extra tablets can be fatal to a child.

Condizioni cardiache (ad es. angina, insufficienza cardiaca)

Se hai una condizione cardiaca, la tua dose deve essere iniziata molto bassa e aumentata lentamente. Contatta immediatamente il tuo medico se avverti dolore al petto o palpitazioni, poiché la levotiroxina aumenta il carico di lavoro sul tuo cuore.

Interazione con integratori (Calcio/Ferro)

Non assumere compresse di calcio, integratori di ferro o multivitaminici contemporaneamente alla levotiroxina. È necessario lasciare un intervallo di almeno 4 ore tra questi integratori e la levotiroxina per garantire l'efficacia del medicinale.

Diabete

La levotiroxina può aumentare i livelli di zucchero nel sangue. Se hai il diabete, devi monitorare più attentamente la glicemia quando inizi o cambi la dose, poiché potrebbe essere necessario aumentare la tua terapia per il diabete.

Avvertenze su cibo e bevande

Alcol

It is best to avoid or strictly limit alcohol when taking these medicines. While there is no direct 'danger' interaction, alcohol can irritate the stomach lining (already a risk with iron) and may interfere with the consistency of your thyroid hormone levels.

Tea and coffee (caffeine)

Tea and coffee contain compounds called tannins and polyphenols that significantly reduce the amount of iron your body can absorb. Avoid drinking these for at least 1 hour before or 2 hours after taking your iron supplement.

Drinking coffee at the same time as taking your levothyroxine can significantly reduce the amount of medicine your body absorbs. Wait at least 30 to 60 minutes after taking your tablet before drinking coffee.

Dairy products (milk, cheese, yoghurt)

Calcium in dairy products prevents iron from being absorbed properly. Do not take your iron supplement at the same time as dairy products. Leave a gap of at least 2 hours.

Whole-grain cereals and eggs

Phytic acid in whole grains and certain proteins in eggs can hinder iron absorption. It is best to take iron on an empty stomach, though you can have a small amount of fruit or vitamin C-rich juice to help absorption.

Soya (soy)

Soya can interfere with how levothyroxine is absorbed by the body. If you eat a lot of soya, your doctor may need to monitor your hormone levels more closely. Try to keep your soya intake consistent and avoid eating it close to the time you take your tablet.

Alghe e kelp

These foods are very high in iodine. Because levothyroxine is a thyroid hormone, high levels of iodine can interfere with your treatment and make your thyroid overactive or underactive.
