For Primary Immunodeficiency Syndrome "I have been infusing Cuvitru subQ weekly in my thighs for more than 4 years, with no pre or post-meds. I started on Hizentra, which gave me many severe side effects, such as flu-like symptoms, probably due to an allergy to the stabilizer L-proline. My immunologist switched me to Cuvitru, which has a different stabilizer, Glycine. The only side effect I get is extreme sleepiness, so I infuse right before bedtime. During the 4 years, I have had two dose increases. My most recent IgG level in June 2022 was 1234, the highest it has ever been. My weekly dose is now up to 16 grams. I love infusing Cuvitru weekly because it is a smaller amount that takes less time, with fewer side effects. Infusing it weekly keeps my IgG levels more balanced out, so I don’t get lower trough levels before the next infusion that can cause severe fatigue for several days. I would recommend Cuvitru to anyone who has PI, especially if you have been on other products that have caused adverse side effects."

For Primary Immunodeficiency Syndrome "I have gluten and dairy intolerances. Not entirely sure the diarrhea I have once or twice a week is from something I've eaten or from the Hizentra (weekly infusions). I feel lightheaded at times, but when one has an intolerance to the above, this symptom is common when I've had something I shouldn't have eaten. It's shortly after the lightheadedness that diarrhea occurs (next morning). Other than that, I fatigue easily, often sleeping 12 to 14 hours. Started Hizentra 4 months ago, so hopefully in another month or two will have more energy."

For Primary Immunodeficiency Syndrome "Overall, I have had the desired results. Since beginning treatment, I have had no further issues of unresolved infection. Any abrasions or illnesses have resolved themselves without the use of antibiotics. The side effects, however, have seemed to slowly increase in numbers and severity. My wife believes I am exaggerating them, but I am not! The number of headaches has increased, but not the severity. The tinnitus has dramatically increased in frequency and intensity. Bouts of recurring nausea increased. Extreme fatigue sometimes for days. Terrible itching and irritation at times. Bloating. Shortness of breath and dizziness at times. Palpitations and racing sensations. Blurry eyes very often. Occasional confusion. And multiple urination issues with back pain."

For Primary Immunodeficiency Syndrome "I infused Hizentra for 3 months, and although I had no infections during that time, my doctor took me off due to adverse side effects. I had flu-like symptoms such as severe fatigue and muscle and joint pain, and felt horrible every day. Eventually, I also had extreme kidney pain after every infusion. There are different stabilizers in each drug, and I was told I was probably allergic to the stabilizer in Hizentra. I switched to Cuvitru, which has a different stabilizer, and I am doing much better, with no pre-meds and minimal side effects. My IG levels are also higher on Cuvitru."
