If You Miss a Dose: Since NSAIDs are sometimes taken only when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose. Do not double a dose. This can be toxic. Keep out of reach of children and pets
