Can I take Anastrozole and Levothyroxine together?

Por qué sucede esto

Anastrozole (used for breast cancer) and levothyroxine (used for an underactive thyroid) are processed by different pathways in the body. They do not interfere with each other's absorption, metabolism, or excretion, nor do they have opposing or overlapping effects on the body's systems.

You can continue to take both medications as prescribed by your doctor. It is usually best to take levothyroxine on an empty stomach, first thing in the morning, at least 30 to 60 minutes before breakfast or taking other medications like anastrozole, to ensure it is absorbed properly. Always inform your doctor if you notice any new symptoms or changes in your health.

Pregnancy and Breastfeeding

You must not take anastrozole if you are pregnant or breastfeeding, as it can cause serious harm to the developing baby. If you are pre-menopausal, you must use effective non-hormonal contraception (such as condoms) during treatment.

Problemas cardíacos (por ejemplo, angina, insuficiencia cardíaca)

Si tiene una afección cardíaca, su dosis debe comenzar muy baja y aumentarse lentamente. Comuníquese con su médico de inmediato si experimenta dolor en el pecho o palpitaciones, ya que la levotiroxina aumenta la carga de trabajo en su corazón.

Calcium or Iron Supplementation

Do not take calcium supplements, iron tablets, or multivitamins at the same time as levothyroxine. You must leave a gap of at least 4 hours between taking these supplements and your levothyroxine dose.

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.

Alimentos (General)

Levothyroxine should be taken on an empty stomach, at least 30 to 60 minutes before breakfast or any caffeinated drinks. Food can significantly interfere with how much medicine your body absorbs.

Cafeína (Café/Té)

Coffee and tea can reduce the absorption of levothyroxine. You should wait at least 60 minutes after taking your tablet before drinking coffee or tea.

Dairy products (Milk/Yoghurt)

Calcium found in dairy products can bind to levothyroxine and prevent it from being absorbed properly. Avoid consuming dairy within 4 hours of taking your dose.

Soja

Soya can interfere with the absorption of levothyroxine. If you eat a lot of soya, your doctor may need to monitor your hormone levels more closely and adjust your dose.

Dietary Fibre

A very high-fibre diet can reduce the absorption of levothyroxine. If you significantly change your fibre intake, inform your doctor as your dose may need adjusting.
