Treatment Options

Routes of Administration and Effects

Administration:

It is most often administered intranasally (snorted), orally (through tablets or powder), sublingually (under the tongue), intravenously (injected), or inhaled (vaporized and inhaled). Injection and inhalation routes are particularly dangerous due to rapid onset and high overdose risk.

Dosage and Effects:

Opioid Effects: Profound analgesia, intense euphoria, sedation, and respiratory depression. Its effects are very similar to fentanyl but may have a slightly longer onset and duration depending on the exact formulation. Compared to typical opioids like morphine, its onset may be faster with a greater risk of fatal respiratory depression.

Adverse Effects: Extreme sedation, confusion, dizziness, nausea, vomiting, constipation, pinpoint pupils (miosis), and dangerous respiratory depression.
