Buy Dihydrocodeine (DHC) is a semi-synthetic opioid analgesic derived from codeine. It’s used primarily for moderate to severe pain relief and sometimes for cough suppression. Chemically, it’s 4,5α-epoxy-3-methoxy-17-methylmorphinan-6α-ol, with the molecular formula C₁₈H₂₃NO₃.

Key Facts and Uses

How It Works

DHC binds to mu-opioid receptors in the brain and spinal cord, reducing pain perception and altering emotional response to pain. It’s about 1/10th as potent as morphine but stronger than codeine (roughly twice as potent). It’s metabolized in the liver via CYP2D6 enzyme to dihydromorphine (active metabolite), contributing to its effects.

Evidence: Clinical studies (e.g., Cochrane reviews on opioids for chronic pain) show efficacy similar to tramadol or codeine for moderate pain, with NNT (number needed to treat for one patient to benefit) around 4–12 depending on dose and condition.

Side Effects and Risks

• Common: Drowsiness, nausea, constipation, dizziness, itching.
• Serious: Respiratory depression (life-threatening overdose risk), addiction, tolerance.
• Overdose Signs: Slow breathing, pinpoint pupils, coma. Naloxone reverses it.
• Interactions: Dangerous with alcohol, benzodiazepines, other opioids (respiratory failure risk). Avoid in asthma, head injuries, or severe liver issues.

Addiction Potential: High—classified as having abuse liability similar to codeine. Long-term use leads to dependence; withdrawal includes anxiety, insomnia, sweating.

Legal Status

• US: Prescription-only (CIII); not approved by FDA for cough but used off-label.
• UK/EU: Prescription-only; available OTC in low-dose combos (e.g., with paracetamol as co-dydramol).
• Global: Controlled under UN Single Convention on Narcotic Drugs.
