Can I take Colecalciferol and Levothyroxine together?

Por qué sucede esto

There is no direct evidence that Vitamin D stops levothyroxine from being absorbed. However, Vitamin D helps the body absorb calcium. If calcium levels in the blood become very high (hypercalcaemia), it can theoretically alter thyroid hormone sensitivity or metabolism. Additionally, if you take Vitamin D as part of a combined calcium supplement, the calcium itself will block the absorption of levothyroxine.

You can take these two medications together. To be safe, it is best to take levothyroxine on an empty stomach, at least 30 to 60 minutes before breakfast or any other medications. If your Vitamin D supplement also contains calcium, you must wait at least 4 hours after taking your levothyroxine before taking the supplement. Your doctor will monitor your thyroid levels (TSH) as part of your routine care.

Hipercalcemia (calcio alto en la sangre)

No tome colecalciferol si tiene niveles altos de calcio en la sangre o en la orina, o si tiene cálculos renales severos, ya que la vitamina D aumenta la absorción de calcio y puede empeorar estas condiciones.

Timing of other medications and supplements

Do not take calcium supplements, iron tablets, or antacids at the same time as levothyroxine. These must be spaced at least 4 hours apart, otherwise the levothyroxine will not be absorbed properly.

Heart disease (e.g. angina, heart failure, or history of heart attack)

Levothyroxine increases the workload on your heart. If you experience chest pain, palpitations, or worsening shortness of breath, you must contact your doctor immediately as your dose may need adjusting.

Diabetes

La levotiroxina puede aumentar los niveles de azúcar en la sangre. Si tienes diabetes, debes controlar tu glucosa en sangre con más cuidado al comenzar o cambiar tu dosis, ya que puede ser necesario aumentar tu medicación para la diabetes.

Alcohol

Es mejor evitar o limitar estrictamente el alcohol mientras se toma colecalciferol. El consumo prolongado y excesivo de alcohol puede interferir con la forma en que tu cuerpo absorbe y procesa la vitamina D, haciendo que el tratamiento sea menos efectivo.

Es mejor evitar o limitar estrictamente el consumo de alcohol mientras se toma levotiroxina. Aunque no hay una reacción química directa, el alcohol puede afectar la función tiroidea y empeorar síntomas como fatiga o cambios de humor.

Cafeína (Café/Té)

Coffee and tea can significantly reduce the amount of levothyroxine your body absorbs. You should wait at least 30 to 60 minutes after taking your tablet before drinking coffee or tea.

Dairy products (Milk/Yoghurt)

Calcium found in dairy products can interfere with the absorption of levothyroxine. Avoid eating or drinking dairy products for at least 30 to 60 minutes after taking your medication.

Productos de soya

Soya can stop levothyroxine from being absorbed properly. If you eat a diet high in soya, you may need a different dose of levothyroxine. Consult your doctor before making major changes to your soya intake.

Papaya

Some evidence suggests that eating large amounts of papaya may reduce the absorption of levothyroxine.

Alimentos ricos en fibra

A diet very high in fibre (such as bran) can reduce the absorption of levothyroxine. Try to keep your fibre intake consistent and discuss any major dietary changes with your doctor.

Comidas ricas en grasa

El colecalciferol es una vitamina soluble en grasa. Se absorbe mejor en tu cuerpo cuando se toma con una comida que contiene algo de grasa (como huevos, aguacate, nueces o lácteos).
