Generic morphine is the non‑branded (generic) form of the opioid medication that is usually sold under brand names such as MS‑Contin, Kadian, or Morphine Sulfate.
It contains the same active ingredient—morphine sulfate—at the same strength and purity as the brand‑name product, but it is typically cheaper because it doesn’t carry the same marketing costs.

• Oral: 10‑30 mg every 4–6 h
• IV: 2 mg every 2–3 h (adjust for tolerance) |
| Schedule | Schedule II in the U.S., meaning it has a high abuse potential but accepted medical uses. |
| Common uses | • Post‑operative pain
• Cancer pain
• Chronic pain in opioid‑tolerant patients |
| Side effects | Drowsiness, constipation, nausea, vomiting, respiratory depression (most serious), sedation, itching. |
| Precautions | • Not for patients with severe respiratory disease or sleep apnea
• Caution in elderly or with hepatic/renal impairment
• Avoid alcohol or other CNS depressants |
| Interactions | • MAOIs, benzodiazepines, SSRIs, alcohol can increase sedation
• CYP2D6 inhibitors/inducers affect metabolism of certain opioid combinations |
| Abuse & Addiction | Can lead to tolerance, physical dependence, and addiction. Must be used exactly as prescribed. |
| Cost | Generics are usually 30‑70 % cheaper than brand‑name equivalents. Insurance often covers them fully after a brand‑name “step‑in” period. |
| Legal status | Prescribed by licensed physicians or other authorized prescribers. Uncontrolled possession is illegal. |

Practical tips
1. Follow the prescription – take exactly as directed, never “double up” if you miss a dose.
2. Swallow tablets whole – crushing can lead to rapid release and overdose risk.
3. Use stool softeners – constipation is almost universal.
4. Keep a medication diary – record dose, time, and pain level to help your provider adjust therapy.
5. Store safely – keep out of reach of children and pets; consider a lock box.
