UNIFERON 3MIU INJ NET

The mechanism of action of Recombinant Human Interferon alfa-2b is primarily attributed to its ability to bind to specific cell surface receptors, initiating a complex signaling cascade within the cell. Upon binding, it triggers the activation of several signaling pathways, including the JAK-STAT pathway, which leads to the transcription of various interferon-stimulated genes (ISGs). These ISGs are responsible for a wide range of antiviral, antiproliferative, and immunomodulatory effects. Interferon alfa-2b induces the production of enzymes that interfere with mRNA and protein synthesis in virus-infected cells, inhibiting viral replication. It also enhances the activity of natural killer cells, macrophages, and cytotoxic T cells, promoting the destruction of infected or malignant cells. Additionally, it modulates the immune response by influencing the expression of cell surface antigens, enhancing antigen presentation, and regulating cytokine production.

In the case of an overdose of Recombinant Human Interferon alfa-2b Injection, the primary concern is the potential for enhanced adverse reactions due to the increased dose. These reactions may include severe flu-like symptoms, such as high fever, chills, fatigue, and muscle pain, as well as gastrointestinal issues like nausea and vomiting. It is crucial to seek medical advice promptly and inform healthcare professionals about the overdose to receive appropriate monitoring and supportive care.

In the case of a missed dose of Recombinant Human Interferon alfa-2b Injection, it is important to consult your healthcare provider for guidance. Generally, if a dose is missed, it is best to inject it as soon as you remember, unless it is close to the time for your next scheduled dose. However, do not double the dose to make up for a missed one. If you miss several doses, contact your doctor to discuss the best course of action and to determine whether any adjustments to your treatment plan are necessary.

To administer the Recombinant Human Interferon alfa-2b Injection, carefully inject the prescribed dose subcutaneously or intramuscularly, as directed by your healthcare professional, ensuring proper needle technique and adhering to the recommended dosage schedule.

• Contraindicated in patients with autoimmune hepatitis or a history of autoimmune disorders.
• Do not use if you have a decompensated liver disease.
• Avoid in patients with severe bone marrow suppression or a history of bone marrow disorders.
• Not suitable for individuals with a history of seizures or epilepsy.
• Should not be used during pregnancy or breastfeeding.
• Not recommended for patients with severe renal impairment or end-stage renal disease.
• Do not administer if the patient has a history of severe cardiovascular disease or unstable ang.

The side effects of Recombinant Human Interferon alfa-2b Injection may include:

• Fever, chills, headache, muscle and joint pain.
• Fatigue and weakness.
• Nausea, vomiting, and loss of appetite.
• Skin reactions at the injection site like redness, swelling, or pain.
• Hair loss or thinning.
• Confusion or dizziness.
• Depression or anxiety.
• Changes in blood cell counts, leading to increased risk of infections or bleeding.

Following are the precautions and warnings for Recombinant Human Interferon alfa-2b Injection:

• Use with caution in patients with pre-existing liver disease, as interferon can exacerbate liver dysfunction.
• Patients with a history of depression or other psychiatric disorders should be closely monitored during treatment, as interferon alfa-2b may cause or worsen psychiatric symptoms, including depression, suicidal ideation, and mood disturbances.
• Caution is required when using this drug in individuals with cardiovascular conditions, as it can cause arrhythmias, hypotension, or other cardiovascular complications.
• Interferon alfa-2b may cause hematologic toxicity, including neutropenia, thrombocytopenia, and anemia. Regular blood counts should be monitored during treatment.
• Use cautiously in patients with autoimmune disorders, as interferon may induce or exacerbate these conditions.
• Caution should be exercised when prescribing this drug to patients with a history of seizure disorders, as it can lower the seizure threshold.
• During pregnancy, Recombinant Human Interferon alfa-2b should only be used if the potential benefits outweigh the risks, as it is classified as pregnancy category C.
• It is unknown if interferon alfa-2b is excreted in breast milk, so use with caution during breastfeeding.
• Patients should be monitored for signs of serious infections, as interferon can impair immune function and increase susceptibility to infections.
• Due to potential risks of severe side effects, use recombinant interferon alfa-2b only under the supervision of a healthcare provider experienced with its use.
• Administer the drug cautiously in patients with renal impairment, as renal function can be affected during therapy.
• Interferon alfa-2b should be used with caution in the elderly, as they may be more prone to adverse effects, including neuropsychiatric and hematologic issues.
• The injection should not be administered to patients with a history of hypersensitivity to interferons or any of the drug components.

Following are the drug interactions for Recombinant Human Interferon alfa-2b Injection:

• Co-administration with zidovudine may increase the risk of hematological toxicity, particularly neutropenia and thrombocytopenia.
• Concurrent use with didanosine can result in mitochondrial toxicity, which may lead to liver dysfunction.
• May decrease the efficacy of vaccines by suppressing the immune response, thus affecting vaccine immunogenicity.
• Bone marrow suppressive agents like azathioprine or mycophenolate mofetil may increase the risk of bone marrow suppression when used together.
• Caution with nucleoside analogs such as ribavirin due to potential additive bone marrow suppression.
• Interferon alfa-2b may exacerbate depression or suicidal ideation when used with antidepressants.
• Concomitant use with theophylline may increase the risk of theophylline toxicity by altering its metabolism.

Following are the food interactions for Recombinant Human Interferon alfa-2b Injection:

• Avoid alcohol consumption during treatment as it may increase the risk of liver toxicity and worsen side effects.
• Grapefruit and grapefruit juice should be consumed with caution as they may interfere with the drug's metabolism, leading to increased blood levels and potential side effects.
• Avoid high-fat meals as they can delay the absorption and reduce the bioavailability of the medication.
• Caffeine intake should be monitored as it may interact with the medication, causing increased anxiety, restlessness, and sleep disturbances.
