When and How to Take Dilantin

Some general considerations for when and how to take the medication include:
  • Dilantin comes in extended-release capsules, chewable tablets, and an oral suspension. These products are not interchangeable.
  • It can be taken with or without food. If it upsets your stomach, try taking it with food. It is important that you take it consistently the same way (either with food or without food).
  • For Dilantin suspension, make sure to shake the medication thoroughly before each dose.
  • Chewable Dilantin Infatabs (tablets) can also be swallowed whole.
  • Do not chew, crush, or open Dilantin Kapseals (capsules), as they are extended-release products.
  • The medication should be taken at the same times each day to maintain even levels of the drug in your blood.
  • For the medication to work properly, it must be taken as prescribed. It will not work if you stop taking it.
  • Do not stop taking it without first discussing it with your healthcare provider (see Dilantin Withdrawal).

Dosing Information

The dosage that your healthcare provider recommends will vary depending on a number of factors, including:
  • The particular Dilantin product
  • Your age and weight
  • The amount of Dilantin in your blood (measured using a blood test)
  • Other medications you may be taking
  • Other medical conditions you may have.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
