Why is this medication prescribed?

Bicalutamide is a medication primarily prescribed for the treatment of prostate cancer. It belongs to a class of drugs called anti-androgens, which work by blocking the action of androgens (male hormones), such as testosterone, on the prostate cancer cells. By doing so, bicalutamide helps to slow down the growth and spread of prostate cancer cells.

It’s usually prescribed either alone or in combination with other medications or treatments, such as surgery or radiation therapy, depending on the stage and aggressiveness of the cancer.

How should this medicine be used?

As for how bicalutamide should be used, it typically comes in the form of oral tablets, and the dosage and frequency can vary depending on factors like the individual’s health condition and the specific treatment plan prescribed by their healthcare provider. Generally, it’s taken once a day with or without food.

It’s crucial to follow the prescribed dosage and schedule provided by the healthcare provider and not to adjust the dosage or stop taking the medication without consulting them first, as doing so can affect the effectiveness of the treatment.

Additionally, it’s essential to inform the healthcare provider about any other medications, supplements, or medical conditions the individual may have before starting bicalutamide, as it may interact with certain drugs or worsen certain health conditions. Regular check-ups and monitoring of prostate-specific antigen (PSA) levels may also be required during treatment with bicalutamide to assess its effectiveness.

Some potential off-label uses of bicalutamide include:

  • Hirsutism: Bicalutamide may be used off-label to treat excessive hair growth (hirsutism) in women by blocking the action of androgens.

  • Polycystic ovary syndrome (PCOS): Bicalutamide may be used off-label in the treatment of PCOS in women to help reduce symptoms associated with excessive androgen levels.

What special precautions should I follow?

As for special precautions to follow when using bicalutamide:

  • Pregnancy and breastfeeding: Bicalutamide should not be used by pregnant women or women who may become pregnant, as it can cause harm to the fetus. Additionally, it is not known whether bicalutamide passes into breast milk, so breastfeeding while taking bicalutamide is not recommended.
  • Liver function: Bicalutamide is metabolized by the liver, so it should be used with caution in individuals with liver impairment. Liver function tests may be conducted before and during treatment with bicalutamide to monitor for any signs of liver toxicity.

What should I do if I forget a dose?

If you forget a dose of bicalutamide, take it as soon as you remember, unless it’s almost time for your next scheduled dose.
