Nimodipine should not be administered IV or by other parenteral routes. Deaths and serious life threatening adverse events have been reported when the contents of nimodipine capsules were injected parenterally. Healthcare providers who prescribe, dispense, or administer nimodipine should be instructed to administer nimodipine capsules orally only. If nimodipine is inadvertently administered IV, clinically significant hypotension may require cardiovascular support with pressor agents. Specific treatments for calcium channel blocker overdose should also be given promptly.

Blood pressure should be monitored carefully during nimodipine therapy.

Safety and effectiveness have not been established in pediatric patients (less than 18 years of age).


Data not available

Since nimodipine is highly protein bound, removal by hemodialysis is unlikely.

Other Comments

For patients unable to swallow a capsule, oral administration may be achieved by using a syringe to extract the gel inside the capsule and administering the nimodipine gel through the patient's nasogastric tube or G-tube. The tube should then be rinsed with 30 mL of normal saline following administration.

Nimodipine should be given at least 1 hour before or 2 hours after meals.
