Medizinische Kohle Zur Anwendung Bei Kindern Und Erwachsenen Dr. Kleine Pharma (Charcoal, Activated)

Activated charcoal is used for gastrointestinal decontamination and symptom relief in several conditions.

• Acute oral poisoning: reduces systemic absorption of ingested toxins.
• Diarrhea: adsorbs excess fluid and toxins to lessen stool frequency.
• Flatulence: binds intestinal gases to alleviate bloating.

• Activated charcoal consists of a porous carbon matrix with a large surface area that physically adsorbs a wide range of organic molecules, gases, and toxins within the gastrointestinal lumen. By binding these substances, it prevents their passage across the intestinal wall, thereby limiting systemic exposure and facilitating elimination in the feces.

Activated charcoal may cause several adverse reactions, most of which are mild and self‑limiting.

Common Side Effects

• Black discoloration of stool: temporary darkening of feces.
• Constipation: reduced bowel movements.
• Nausea: feeling of unease in the stomach.
• Vomiting: expulsion of stomach contents.
• Abdominal discomfort: mild cramping or pain.
• Taste alteration: unpleasant after‑taste.

Serious or Rare Side Effects

• Aspiration pneumonia: risk if material is inhaled.
• Severe constipation leading to bowel obstruction.
• Electrolyte imbalance: especially with prolonged use.
• Allergic reaction: rash, itching, or angioedema.
• Hemodynamic changes: rare hypotension.
• Metabolic acidosis: extremely rare with large doses.

When using activated charcoal, consider the following safety measures.

• Dose adjustment: pediatric dosing should be determined by a qualified healthcare professional.
• Contraindication: avoid in patients with known intestinal obstruction, perforation, or severe ileus.
• Interaction caution: may reduce absorption of concurrently administered oral medications; separate administration times.
• Pregnancy: safety not established; use only if potential benefit outweighs risk.
• Monitoring: observe for signs of severe constipation or bowel blockage.
• Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Activated charcoal can affect the pharmacokinetics of several drugs.

Major Interactions (Avoid)

• Antacids (aluminum, magnesium): bind charcoal and diminish its adsorptive capacity.
• Oral iron supplements: charcoal adsorbs iron, reducing absorption.
• Tetracycline antibiotics: charcoal reduces therapeutic levels of the antibiotic.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: possible reduction in hormone levels; consider backup contraception.
• Lithium: charcoal may lower serum lithium concentrations; monitor levels.
• Warfarin: potential decrease in anticoagulant effect; monitor INR closely.
