Groprinosin (Inosine Pranobex)

Groprinosin is indicated for use in several viral and immunodeficiency conditions where immune support is beneficial.

• Management of herpes simplex virus infections, including recurrent oral or genital lesions.
• Treatment of human papillomavirus (HPV) infections, particularly in cases with persistent warts.
• Adjunct therapy for influenza and other acute viral respiratory infections.
• Supportive care in immunodeficiency states, such as secondary immunosuppression.
• Off‑label use in certain chronic viral infections under clinical supervision.

Side effects of Groprinosin vary in frequency and severity. Most patients experience mild, transient reactions, while rare serious events may require medical attention.

Common

• Nausea or mild gastrointestinal upset.
• Headache or dizziness.
• Transient rash or mild skin irritation.
• Mild fatigue or feeling of weakness.

Serious

• Severe allergic reactions, including anaphylaxis.
• Significant liver enzyme elevations.
• Hematologic abnormalities such as leukopenia.
• Persistent high fever or unexplained chills.

Before starting Groprinosin, certain precautions should be considered to ensure safe use.

• Assess liver function, as the drug may affect hepatic enzymes.
• Monitor complete blood counts, especially in patients with pre‑existing hematologic disorders.
• Use cautiously in pregnant or breastfeeding individuals; data are limited.
• Evaluate for known hypersensitivity to inosine pranobex or any excipients.
• Adjust dosage in patients with severe renal impairment under specialist guidance.
• Inform healthcare providers of any concurrent immunosuppressive therapy.

Groprinosin can interact with other medicines, influencing efficacy or safety. Awareness of these interactions helps prevent adverse outcomes.

Avoid

• Concurrent use with potent immunosuppressants that may counteract its immunostimulatory effect.
• Combination with drugs known to cause severe liver toxicity.

Use with caution

• Anticoagulants, as immune modulation may affect coagulation parameters.
• Vaccines, particularly live attenuated vaccines, due to altered immune response.
• Other antiviral agents, which may require dose adjustments.
• Herbal supplements that influence immune function, such as echinacea or ginseng.
