How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- IVIG brands are not interchangeable: they differ in concentration, stabilizers, sugar content, and approved uses, so a switch needs a doctor's decision.
- Gammagard Liquid, Gamunex-C, Privigen, Octagam, and Panzyga are intravenous options, while Hizentra, Cuvitru, and HyQvia are subcutaneous options.
- Subcutaneous products suit patients who prefer home infusions with smaller, more frequent doses, while intravenous products suit clinic-based treatment.
- This article is general information only and is not medical advice. Treatment choices must be made with a doctor who knows your condition, history, and lab results.
- Prices are not published for these prescription products, so all prices here are listed as See website, and actual cost depends on dose, insurance, and setting.

The best ivig alternatives
#1
Gammagard Liquid
Best for: intravenous immune globulin therapy in clinics
Visit takeda.com
Starting priceSee website
Free planNo
Gammagard Liquid is an intravenous immune globulin product from Takeda, used for primary immunodeficiency and other conditions where immune globulin replacement or modulation is prescribed. It is given by intravenous infusion in a clinic or infusion center, with doses and schedules set by the treating doctor based on weight, condition, and response.
The product has a long track record and broad approved uses, which makes it a common first choice. The main burden is time: infusions take hours, and venous access is needed. Side effects and suitability vary by patient, so a doctor must weigh kidney function, clotting risk, and other factors before prescribing. Never switch to or from this product without medical guidance.
What we like- Widely used
- Broad approved uses
- Long track record
Watch out for- Clinic infusions take hours
- Intravenous access needed
#2
Gamunex-C
Best for: patients whose doctor wants intravenous or subcutaneous flexibility
Visit grifols.com
Starting priceSee website
Free planNo
Gamunex-C, from Grifols, is an immune globulin product that can be given intravenously or subcutaneously, depending on the approved use and the doctor's plan. That flexibility suits patients whose needs change over time, since the same brand can support a move from clinic infusions to home subcutaneous treatment when the doctor judges it appropriate.
Dosing, concentration, and infusion rates differ by route, so the two forms are not simply swapped. The product has broad approved uses, including primary immunodeficiency and certain autoimmune conditions. As with all immune globulin products, the treating doctor must decide suitability based on the individual patient's history and labs.
What we like- Can be given intravenously or subcutaneously
- Broad approved uses
Watch out for- Dosing differs by route
- Needs careful medical supervision
Starting priceSee website
Free planNo
Privigen, from CSL Behring, is an intravenous immune globulin product used for primary immunodeficiency and other approved conditions. It is given in clinics or infusion centers, with dosing set by weight and condition. The product is widely used and well studied, which gives doctors a large body of experience to draw on.
Privigen uses proline as a stabilizer, which matters for patients with certain metabolic conditions, and kidney function and clotting risk must be assessed before use. Infusion reactions can occur, especially early in treatment, so monitoring during and after infusion is standard. Suitability is an individual medical decision, not a general ranking.
What we like- Widely used
- Broad approved uses
- Well studied
Watch out for- Clinic infusions take hours
- Stabilizer content matters for some patients
Starting priceSee website
Free planNo
Octagam, from Octapharma, is an intravenous immune globulin product available in multiple concentrations, which gives doctors flexibility in infusion volume and rate. It is used for primary immunodeficiency and other approved conditions, with dosing set by the treating doctor. The product has a long history of use in many countries.
As with other intravenous products, infusions take hours in a clinic setting, and venous access is needed. Blood sugar, kidney function, and clotting risk are among the factors a doctor checks before prescribing, since stabilizers and product composition differ across brands. Patients should discuss their full medical history with their doctor before any switch.
What we like- Multiple concentrations
- Broad approved uses
- Long use history
Watch out for- Clinic infusions take hours
- Intravenous access needed
#5
Panzyga
Best for: intravenous therapy from a large manufacturer
Visit pfizer.com
Starting priceSee website
Free planNo
Panzyga, from Pfizer, is an intravenous immune globulin product used for primary immunodeficiency, chronic immune thrombocytopenia, and chronic inflammatory demyelinating polyneuropathy, among its approved uses. It is given by intravenous infusion in a clinic, with dosing set by the treating doctor based on weight and condition.
Panzyga is a newer brand than some on this list, though immune globulin therapy itself is well established. Availability varies by region, and insurance coverage depends on the approved use and the patient's plan. As with all products here, the choice must be made with a doctor who knows the patient's condition and history.
What we like- Broad approved uses
- Large manufacturer support
Watch out for- Clinic infusions take hours
- Availability varies by region
Starting priceSee website
Free planNo
Hizentra, from CSL Behring, is a subcutaneous immune globulin product designed for home use, mainly for primary immunodeficiency. Patients or caregivers give smaller doses under the skin, usually weekly, after training from a healthcare team. Home treatment avoids clinic visits and venous access, which many patients prefer.
The trade-off is frequency: subcutaneous doses are smaller and more frequent than intravenous doses, and local reactions at the infusion site, such as swelling or redness, are common. Training, supplies, and a support contact are part of safe home use. A doctor must decide whether home subcutaneous therapy suits the patient's condition and ability to self-infuse.
What we like- Home infusions
- Smaller, more frequent doses
- No venous access needed
Watch out for- Frequent infusions
- Local site reactions are common
#7
Cuvitru
Best for: subcutaneous home therapy with flexible dosing
Visit takeda.com
Starting priceSee website
Free planNo
Cuvitru, from Takeda, is a subcutaneous immune globulin product for primary immunodeficiency, given at home after training. Doses are given under the skin at one or more sites, with frequency and volume set by the doctor. Home treatment suits patients who want independence from clinic schedules and who can manage self-infusion.
Like other subcutaneous products, Cuvitru needs frequent infusions, and local site reactions are common. The product's concentration and dosing differ from other brands, so doses are not converted by simple arithmetic. A doctor and a specialty pharmacist should oversee any start or switch, with lab monitoring as needed.
What we like- Home infusions
- Flexible dosing sites
- No venous access needed
Watch out for- Frequent infusions
- Local site reactions are common
Starting priceSee website
Free planNo
HyQvia, from Takeda, is a subcutaneous immune globulin product that uses recombinant human hyaluronidase to help larger volumes spread under the skin, allowing less frequent dosing, often monthly, for many patients. It is given at home after training, which combines home convenience with a less frequent schedule than weekly subcutaneous products.
The infusion volumes are larger than other subcutaneous products, and the two-step process needs careful training. Local reactions can still occur, and the product is approved for specific uses, mainly primary immunodeficiency in adults and children. A doctor must decide whether the monthly schedule and larger volumes suit the individual patient.
What we like- Monthly dosing for many patients
- Home use
- No venous access needed
Watch out for- Larger infusion volumes
- Needs recombinant hyaluronidase step
How we chose
We compared these products on route of administration, approved uses, dosing frequency, home versus clinic use, and manufacturer information. We checked manufacturer pages and public regulatory information, and where prices were not published we wrote See website instead of guessing, since these are prescription products whose cost depends on dose, insurance, and setting. We kept the list to products available in the United States, and we left out products with very narrow or discontinued status.
How to discuss IVIG options with your doctor
Start with your current treatment experience. Tell your doctor what works and what does not: infusion time, travel, side effects, site reactions, and how treatment fits your daily life. That lived experience matters, because a product that is medically suitable but hard to live with will fail in practice. Bring a list of all medicines and conditions, since immune globulin suitability depends on kidney function, clotting risk, blood sugar, and other factors.
Next, ask about the practical differences between routes. Intravenous products need clinic time and venous access but less frequent dosing, while subcutaneous products allow home treatment with more frequent doses. Ask about training, supplies, support contacts, and what to do if a dose is missed or a reaction occurs. Also ask about insurance coverage and specialty pharmacy steps, since authorization and delivery can take weeks.
Finally, never switch products on your own. Brands differ in composition, stabilizers, and concentration, and a dose that works for one brand does not transfer directly to another. Any switch needs a doctor's plan, including dosing, monitoring, and a follow-up schedule. If cost is a barrier, ask your doctor and pharmacist about patient assistance programs, since manufacturers and nonprofits offer support for qualifying patients.
Frequently asked questions
Are IVIG brands interchangeable?
No. IVIG brands differ in concentration, stabilizers, sugar content, and approved uses, and doses do not transfer directly between brands. Any switch must be planned by a doctor, with dosing and monitoring adjusted for the new product.
What is the difference between IVIG and SCIG?
IVIG is given intravenously in a clinic, usually every three to four weeks, while SCIG is given subcutaneously at home, usually weekly, except HyQvia, which is often monthly. IVIG needs venous access and clinic time, while SCIG needs self-infusion training and more frequent doses.
Can I infuse at home?
Home infusion is possible with subcutaneous products after training from a healthcare team, and some intravenous products support home infusion in certain programs. Your doctor and specialty pharmacy decide whether home treatment is safe for you, based on your condition and history.
What side effects should I watch for?
Common issues include headache, fatigue, infusion-site reactions for subcutaneous products, and flu-like symptoms. Serious risks, though less common, include kidney problems, clotting events, and severe allergic reactions. Report new symptoms to your doctor promptly, and seek urgent care for chest pain, breathing difficulty, or signs of a severe allergic reaction.
How much does IVIG cost?
Cost depends on dose, product, setting, and insurance, and prices are not published for these prescription products. Ask your specialty pharmacy for a cost estimate after authorization, and ask about patient assistance programs if cost is a barrier. Do not skip doses for cost reasons without talking to your doctor.
Where can I get help making this decision?
Start with your treating doctor, who knows your condition and history, and ask for a referral to an immunologist if you do not already have one. Patient organizations such as the Immune Deficiency Foundation offer education and support, and your specialty pharmacist can explain practical details about dosing and delivery.
