|---|---|
| 12 mcg/hr | Requirement starting dose for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dose for escalating chronic pain. |
| 50 mcg/hr | High-strength dosage; requires close tracking. |

| 100 mcg/hr | Maximum standard patch strength. |

These are utilized 'as required,' however with strict limits on frequency.
| Solution Type | Typical Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |
