| 12 mcg/hr | Standard beginning dosage for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dose for escalating persistent pain. |
| 50 mcg/hr | High-strength dosage; requires close tracking. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Optimum basic spot strength. |

These are utilized 'as needed,' but with stringent limits on frequency.
| Formula Type | Common Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |
