Inform your healthcare provider about any other medications or supplements you are currently taking to avoid potential interactions.

For elderly patients, dose selection should be cautious, usually starting at the low end of the dosing range, due to the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Pregnant or breastfeeding individuals should consult their healthcare provider before using Isordil, as the effects of the medication in these situations are not well-established.
