🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by supplying a broad spectrum of intact human immunoglobulin G antibodies that bind to pathogens, toxins, and immune receptors. It neutralises infectious agents, promotes their clearance by immune cells, and blocks Fc receptors on inflammatory cells. It also modulates complement activation, cytokine production, and B-cell and T-cell function, which helps dampen autoimmune damage. In antibody deficiency, it simply replaces what the body cannot make.

💡 How to Take iviglob 2.5gm infusion
Strength: Human Normal Immunoglobulin 2.5 gram injection
Dosage Information
| Adult Dosage | The dose of this medicine depends on the condition being treated, the patient's weight, and whether it is given for replacement therapy or immune modulation. For immunodeficiency, doses are often calculated as 300 to 600 milligrams per kilogram of body weight every three to four weeks. For immune thrombocytopenia, a common regimen is 400 milligrams per kilogram daily for five days or 1 gram per kilogram daily for one to two days. For Guillain-Barré syndrome, a typical dose is 400 milligrams per kilogram daily for five days. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. When this medicine is used in children, the dose is calculated by body weight and the indication, and it must be prescribed and supervised by a pediatric specialist. |
| Elderly Dosage | Older adults may need a slower infusion rate and careful monitoring of kidney function, blood pressure, and blood clotting. The dose is usually similar to adults, but it must be individualized by a qualified clinician based on kidney function, heart function, and the underlying condition. |
| Renal Impairment | Patients with kidney disease need special care. The infusion rate should be as slow as possible, and the dose may need to be reduced or the product avoided if kidney function is severely impaired. Adequate hydration is essential. Dose must be individualized by a qualified clinician. |
| Hepatic Impairment | No specific dose adjustment is established for liver disease. Patients with liver problems should be assessed by their doctor before treatment because the underlying condition may affect how this medicine is used. |
| Maximum Daily Dose | The maximum daily dose depends on the indication and the patient's weight. High-dose regimens such as 1 gram per kilogram per day may be used for a limited number of days under specialist supervision. Dose must be individualized by a qualified clinician. |

🤱 Lactation Safety
Human normal immunoglobulin is a normal component of breast milk and is not expected to harm a breastfed baby. However, you should discuss breastfeeding with your doctor before starting treatment.
💊 Overdose Management
Overdose with this medicine is unlikely because it is given by healthcare professionals. If too much is given, the patient should be monitored for fluid overload, high blood viscosity, and kidney problems. Treatment is supportive and may include hydration and close observation.
⏰ Missed Dose
If you miss a scheduled dose of this medicine, contact your doctor or infusion centre as soon as possible. Do not try to catch up by taking a double dose. Your doctor will decide when to give the next dose based on your treatment plan.
Additional Safety Advice
This medicine must only be given by a qualified healthcare professional in a setting where allergic reactions can be managed. Before treatment, tell your doctor about any previous reaction to immunoglobulin or blood products, kidney disease, heart disease, diabetes, blood clotting problems, or IgA deficiency. Adequate hydration before and during treatment helps protect the kidneys. Your doctor may check kidney function, blood counts, and blood clotting before and after treatment. Do not drive or operate machinery immediately after the infusion if you feel dizzy or tired. Keep all follow-up appointments so that your dose and response can be reviewed. Never self-administer this medicine at home unless a trained nurse or doctor has specifically arranged and supervised home infusion.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Older adults may be more prone to kidney problems, blood clots, and heart strain with this medicine. The infusion should be given slowly, and kidney function, blood pressure, and hydration should be checked carefully. The dose is usually similar to younger adults but must be individualized by a qualified clinician.
🤰 Pregnancy Planning (TTC)
If you are planning pregnancy, discuss this medicine with your doctor before conception. Human normal immunoglobulin has been used in pregnancy when clinically needed, but the decision should be made with your obstetrician and specialist. Do not stop or start treatment without medical advice.
🏥 Post-Surgery Considerations
If you have surgery planned, tell your surgeon and anaesthetist that you receive this medicine. It can affect blood clotting and increase the risk of clots in some patients. Your treatment schedule may need to be adjusted around surgery, and monitoring may be needed after the operation.
🦷 Dental Procedures
Inform your dentist that you receive this medicine, especially if you have a bleeding disorder or low platelets. Routine dental work is usually safe, but extra care may be needed if your platelet count is low or if you have a history of bleeding. Your doctor can advise whether any precautions are needed before dental treatment.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
Light activity such as walking is usually fine after infusion, but avoid strenuous exercise or heavy lifting on the same day. If you feel dizzy, tired, or have a headache, rest and drink fluids. Patients with Guillain-Barré syndrome or neuropathy should follow their physiotherapist's advice about gradual strengthening.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
Most people can return to work or normal activities the day after infusion, but some may feel tired or have a headache for a day. Avoid driving or operating heavy machinery if you feel dizzy or unwell. Plan your infusion days around important work or family commitments, and inform your employer if you need regular time off for treatment.
🛑 When to Stop This Medicine
Do not stop this medicine on your own. Your doctor will decide when to stop based on your condition, response to treatment, and side effects. If you develop a serious reaction such as severe allergic symptoms, kidney problems, or blood clots, treatment may be stopped immediately and alternative options considered.
📅 Long-Term Use Effects
Long-term use of this medicine is generally well tolerated when monitored properly. Patients on regular replacement therapy may need periodic checks of kidney function, blood counts, and immunoglobulin levels. Rarely, repeated high-dose treatment can cause kidney strain, blood clots, or low neutrophil counts. Your doctor will review the dose and frequency regularly to balance benefit and risk.
🌿 Non-Medicine Approaches
These can complement medicine but do not replace prescribed treatment.
An alternative route for replacement therapy that can sometimes be given at home after training.

💉 If You're Getting Vaccinated
This medicine can reduce the response to live vaccines such as measles, mumps, rubella, and varicella vaccines. Live vaccines should be postponed for about three months after a high dose, or longer if a very high dose was given. Inactivated vaccines are generally safe but may need to be given before treatment or repeated later. Discuss all vaccinations with your doctor.
