Kaloba (Pelargonium Sidoides Root Liquid Extraction Preparation (1 : 8-10), Extraction Solvent: Ethanol 11 %)

• Kaloba is an over‑the‑counter herbal preparation that belongs to the cough and cold therapeutic class and is used within the respiratory infection family to relieve symptoms associated with acute bronchitis, cough and upper respiratory tract infections.
• Acute bronchitis: helps reduce cough frequency and improve mucus clearance.
• Cough: provides symptomatic relief of dry or productive cough.
• Upper respiratory tract infection: supports reduction of congestion and throat irritation.

• The exact mechanism of Pelargonium sidoides root extract is not fully elucidated. Pre‑clinical studies suggest that the preparation contains polyphenols and coumarins that exhibit antimicrobial activity against common respiratory pathogens and may modulate the host immune response by enhancing macrophage activity and cytokine production, thereby facilitating clearance of infection and reducing inflammation in the airways. It may also influence mucociliary clearance, contributing to symptomatic improvement.

Kaloba may be associated with a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

• Gastrointestinal discomfort: mild nausea, stomach upset or diarrhoea.
• Altered taste: temporary bitter or metallic taste in the mouth.
• Headache: mild headache reported by some users.
• Dizziness: occasional light‑headedness, especially after higher doses.
• Dry mouth: reduced salivation leading to mild throat dryness.
• Insomnia: occasional difficulty falling asleep.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response requiring immediate medical attention.
• Liver enzyme elevation: rare cases of increased transaminases.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

• When considering Kaloba, several precautionary measures should be observed to ensure safe use.
• Pregnancy: safety not established; use only if benefit outweighs potential fetal risk.
• Breastfeeding: caution advised as the extract may pass into milk; seek advice.
• Children: use under pediatric guidance; dosage may differ from adult recommendations.
• Liver disease: monitor liver function because rare enzyme elevations have been reported.
• Drug interactions: consult a healthcare professional before combining with other medicines.
• Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight.

Kaloba can interact with other medicines; the nature of the interaction determines the level of monitoring required.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): concurrent use may increase bleeding risk; avoid combining without medical supervision.
• Immunosuppressants (e.g., cyclosporine): may reduce immunosuppressive efficacy; avoid concurrent administration.

Moderate Interactions (Monitor Closely)

• CYP450 substrates (e.g., statins, oral contraceptives): possible alteration of plasma levels; monitor therapeutic response.
• Antihistamines: additive sedative effect may occur; observe for excessive drowsiness.
• Other herbal products (e.g., echinacea, ivy leaf): combined immunomodulatory activity could enhance effects; assess clinical response.
