Formaldehyde Injection: Extreme Danger and Medical Emergency

Intravenous formaldehyde injection is life-threatening. Formaldehyde (formalin) is a potent protein cross-linker and fixative — used for tissue preservation, never for human injection.

Immediate Effects

• Severe chemical hemolysis, thrombosis, vascular damage.
• Excruciating pain at injection site and along vein.
• Acute kidney injury (hemoglobinuria).
• Metabolic acidosis (formic acid metabolite).
• CNS: seizures, coma, blindness (retinal toxicity).
• Cardiovascular collapse.

Long-Term Consequences (If Survived)

• Permanent organ damage (kidney, liver, nerve).
• Carcinogenicity (nasopharyngeal leukemia).
• Reproductive toxicity.
• Tissue necrosis, limb loss.

Emergency Response

1. Call emergency services immediately.
2. Do NOT induce vomiting.
3. IV fluids, bicarbonate for acidosis, hemodialysis for formate clearance, supportive ICU care.
4. Poison control: 1-800-222-1222 (US).

This is a medical catastrophe. Never inject formaldehyde or any non-pharmaceutical substance.
