What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Directions

Gammagard Liquid should be administered under the supervision of a healthcare professional experienced in immunoglobulin therapy. For IV use, the recommended dose for patients with PI typically ranges from 300 to 600 mg/kg body weight every 3 to 4 weeks. For SC use, a loading dose may be administered over several days, followed by weekly maintenance doses adjusted according to serum IgG levels and clinical response. Patients with MMN generally receive doses based on individual response and tolerability, with infusions repeated every 2 to 4 weeks. Infusion rates should be gradually increased as tolerated, with close observation during administration.

Ingredients

Each milliliter of Gammagard Liquid contains 100 mg of immunoglobulin G (IgG). The solution may also include small amounts of glycine as a stabilizer and water for injection. Gammagard Liquid is preservative-free and contains no added sugars, latex, or mercury.

Cautions

Before starting Gammagard Liquid, clinicians should assess the patient's renal function and thrombotic risk factors. Use caution in individuals with diabetes mellitus, volume overload, or a history of renal impairment. Ensure patients are well hydrated before administration. Monitoring is essential for patients receiving high doses or rapid infusions, particularly the elderly or those with comorbid conditions. As with all blood-derived products, there is a minimal risk of transmitting infectious agents, although rigorous screening and viral inactivation steps are applied.

Contraindications

Gammagard Liquid is contraindicated in individuals with a history of anaphylactic or severe systemic reactions to human immunoglobulin preparations. It is also contraindicated in patients with IgA deficiency who have developed antibodies against IgA, as they are at increased risk of hypersensitivity reactions.

Side Effects

Common side effects associated with Gammagard Liquid may include:

  • Headache
  • Chills or fever
  • Fatigue
  • Nausea
  • Back or joint pain
  • Local reactions at the injection site (for SC use) such as swelling, redness, or itching

Severe but rare side effects may include anaphylaxis, aseptic meningitis, hemolysis, renal dysfunction, and thromboembolic events. Immediate medical attention is advised if symptoms of a serious allergic reaction occur.
