It is not known if INVOKANA® is safe and effective in children under 18 years of age.
INVOKANA® can cause important side effects, including:

Yeast infection of the penis (balanitis or balanoposthitis). Men who take INVOKANA® may get a yeast infection of the skin around the penis.

redness, itching, or swelling of the penis
rash of the penis
foul smelling discharge from the penis
pain in the skin around penis

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take two doses of INVOKANA® at the same time. Talk to your doctor if you have questions about a missed dose.
If you take too much INVOKANA®, call your doctor or go to the nearest hospital emergency room right away.
