Inosine Pranobex Q Pharma Kft. (Inosine Pranobex)

Inosine Pranobex is used as an antiviral immunostimulant to enhance host defenses against several viral infections.

• Herpes simplex infections: reduces lesion duration and viral shedding by stimulating cellular immunity.
• Human papillomavirus infections: supports clearance of HPV lesions through immune activation.
• Influenza: helps shorten illness course and severity by augmenting antiviral response.
• Immunodeficiency‑related viral infections: aids control of opportunistic viral diseases in immunocompromised patients.

• Inosine Pranobex exerts its antiviral immunostimulant effect by promoting lymphocyte proliferation, enhancing natural killer cell activity, and increasing production of cytokines such as interferon‑γ and interleukin‑2. The compound also interferes with viral replication by modulating host cell metabolic pathways, leading to broad‑spectrum activity against DNA and RNA viruses. These immunomodulatory actions result in enhanced clearance of infected cells and reduced viral load.

Inosine Pranobex may be associated with several adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: transient headache episodes.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Leukopenia: significant reduction in white blood cells.
• Hepatic dysfunction: elevated liver enzymes or hepatitis.
• Severe allergic reaction: anaphylaxis or angioedema.

Use of Inosine Pranobex requires careful consideration of patient-specific factors.

• Pregnancy: safety not established; use only if benefit outweighs risk.
• Breastfeeding: unknown; consider potential exposure to infant.
• Renal impairment: dose adjustment may be required.
• Hepatic impairment: monitor liver function during therapy.
• Concomitant immunosuppressants: may reduce therapeutic efficacy.
• Store at below 25°C: keep in the original pack, protect from moisture and light.

Inosine Pranobex can interact with other medicines; awareness of these interactions helps maintain safety and effectiveness.

Major Interactions (Avoid)

• Immunosuppressive agents: may counteract the drug’s immune‑enhancing effect.
• Live vaccines: increased risk of infection due to altered immune response.

Moderate Interactions (Monitor Closely)

• Corticosteroids: may diminish the immunostimulant benefit.
• Anticoagulants: potential for altered platelet function.
• Other antivirals (e.g., acyclovir): additive antiviral activity may increase toxicity risk.
