Can I take Biotin and Tamoxifen together?

Por que isso acontece

Biotin does not change how tamoxifen is absorbed, broken down, or used by the body. However, biotin is often used in laboratory testing technology. Taking high doses of biotin can cause 'false' results in hormone tests (like oestrogen or thyroid tests) and tumour marker tests, which your doctor may use to monitor your treatment.

It is generally safe to take these together. However, you must tell your doctor and the laboratory staff that you are taking biotin before having any blood tests. Most experts recommend stopping biotin supplements at least 48 to 72 hours before a blood test to ensure the results are accurate.

Laboratory blood tests (e.g. thyroid or heart attack tests)

Biotin can significantly interfere with laboratory blood tests, leading to false results. You must stop taking biotin at least 48 hours before having any blood work and inform your doctor you are taking it.

Blood clots (Thrombosis)

Tamoxifen significantly increases your risk of serious blood clots in the legs or lungs. Seek immediate medical help if you experience sudden shortness of breath, chest pain, or a painful, swollen calf.

Câncer de útero (matriz)

Tamoxifen can increase the risk of changes to the lining of the womb, including cancer. You must report any unusual vaginal bleeding, spotting, or changes in vaginal discharge to your doctor immediately.

Toranja e suco de toranja

Grapefruit can interfere with how your body processes tamoxifen, potentially making the medicine less effective. It is best to avoid consuming grapefruit products while taking this medication.

Álcool

While there is no direct chemical interaction, alcohol can worsen certain side effects of tamoxifen, such as hot flushes. Additionally, heavy drinking can impact liver health, which is important since tamoxifen is processed by the liver. Moderate consumption is usually acceptable, but check with your doctor.

Claras de ovo cruas

Consumir grandes quantidades de claras de ovo cruas por um longo período pode impedir que seu corpo absorva biotina. Isso ocorre porque as claras de ovo cruas contêm uma proteína chamada avidina que se liga à biotina. Ovos cozidos não causam esse problema.
