Medications that might interact with this drug

Interactions that increase your risk of side effects
  • Side effects from other drugs: Taking bicalutamide with certain medications raises your risk of side effects from these drugs. Examples of these drugs include:

Interactions that can make your drugs less effective
  • When other drugs are less effective: When certain drugs are used with bicalutamide, they may not work as well. This is because the amount of these drugs in your body may be decreased. Examples of these drugs include:

People with liver disease

This drug is broken down by your liver. If your liver doesn’t work as well as it should, this drug may build up in your body. Your doctor will likely do blood tests to check how well your liver works before and during your treatment. They may do these tests every month for the first 4 months of your treatment, and from time to time during the rest of your treatment.

People with diabetes

Your doctor may ask you to test your blood sugar levels more often. This drug is used with an LH-RH analogue. These medications can reduce your body’s glucose tolerance. This means that your body is less able to use sugar from your blood. This effect leads to high blood sugar levels.
