General Information on Dosing With Isoptin SR

Considerations for people taking Isoptin SR include the following:
  • The medication comes in tablet form. It is taken by mouth, usually once or twice daily.
  • Isoptin SR should be taken with food.
  • Isoptin SR tablets contain extended-release beads that slowly release the medication over time. Be sure to swallow the tablets whole.
