What Should I Do If I Miss My Niacin Dose?

For immediate-release niacin, if you forget to take a dose, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose. For slow-release or extended-release niacin products (which are taken just once a day, usually at bedtime), it is probably best to simply skip a missed dose.
 
If you miss several niacin doses, you will probably need to restart back at a low dose and slowly work up to your previous dosage (just like when starting the medication for the first time), in order to avoid intolerable side effects.
