| 75 mcg/hr | 12.6 mg | High-dose management for advanced illness or cancer discomfort. |
| 100 mcg/hr | 16.8 mg | Optimum single spot strength; dosages can be integrated to exceed 100 mcg. |

| MAOIs | Certain antidepressants (within 14 days of usage). | Danger of serotonin syndrome or severe CNS toxicity. |
| Existing Conditions | Serious breathing deficiency or intense lung illness. | Stress of breathing difficulties. |
