  • other conditions you may have

If you miss your regular dose of Viibryd, take it as soon as you remember. But if it’s too close to your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses at once, as this could increase your risk of side effects.

If you miss two or more Viibryd doses in a row, call your doctor to discuss your options. They’ll determine if you should restart the drug at a lower starting dose or if you can continue with your current dosing. Do not suddenly stop taking Viibryd, as this can increase your risk of certain side effects.

These side effects should go away once you’re back on track with your regular dosing schedule.
