To make sure estramustine is safe for you, tell your doctor if you have:
a history of blood clot, stroke, or heart attack;
high blood pressure (hypertension);
congestive heart failure;
epilepsy or other seizure disorder;

Take estramustine on an empty stomach, at least 1 hour before or 2 hours after a meal.
Take this medicine with water, not with milk or other dairy products.
It may take up to 90 days before you receive the full benefit of taking estramustine. Your doctor will determine how long to treat you with estramustine.
While using estramustine, you may need frequent blood tests. Your blood pressure will also need to be checked often.

What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
