If you forget to take your Xtandi dose, take it as soon as you remember and then stick to your usual schedule. If you miss a day, simply take your next dose at the regular time the following day. Make sure not to take more than the prescribed amount of Xtandi in a single day. If you skip your dose for more than one day, you should contact your doctor right away. It’s crucial to follow your doctor’s instructions closely when taking Xtandi, and never change or stop your dosage without first getting advice from your doctor.
