What Does This Mean For Me?

It's important to know that many side effects go away during treatment as your body adjusts to the medicine. While these side effects usually do not require medical intervention, you should report them to your health care provider if they continue for over one week, or if they interfere with your daily routine. Your doctor may decide to adjust your dosage or switch you to another medication entirely.

Also, you may experience other, less common side effects. If you do, alert your doctor. You should never stop or change the dosage of your medication on your own.
