Can I take Anastrozole and Levothyroxine together?

لماذا يحدث هذا

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.

أمراض القلب (مثل الذبحة الصدرية، فشل القلب)

إذا كنت تعاني من حالة قلبية، يجب أن تبدأ جرعتك بكمية منخفضة جدًا وتزداد ببطء. اتصل بطبيبك فورًا إذا شعرت بألم في الصدر أو خفقان، حيث أن الليفوثيروكسين يزيد من العبء على قلبك.

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.

السكري

يمكن أن يرفع ليفوثيروكسين مستويات السكر في الدم. إذا كنت مصابًا بداء السكري، يجب عليك مراقبة مستوى الجلوكوز في الدم عن كثب عند بدء أو تغيير جرعتك، حيث قد تحتاج إلى زيادة جرعة دواء السكري الخاص بك.

الطعام (عام)

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.

الكافيين (القهوة/الشاي)

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.

Soya

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.
