FDA Adverse Event / Side-effect Report 6 -- Synvisc (H-G 20)

The FDA MAUDE site still fails to show descriptions such as the following relating to Synvisc injections or any other medical device as of late Sept 2009. As a person who went from INCREDIBLE health to barely surviving and hanging on the last 2 years DIRECTLY FOLLOWING SYNVISC injections, these event descriptions are TOO important to keep to myself. People need to know what COULD happen if they consent to Synvisc injections. And the probability is historically HIGH that Genzyme, your injecting physician and other physicians will NOT be on your side if something goes wrong. Had I known this information prior to my consent, the last 2 years of my life would've been MUCH healthier and productive...and there are many who've contacted me privately who experienced the same! Take HEED before you consent to this product, and do your research before you consent to ANY DRUG or MEDICAL DEVICE. Unfortunately the FDA just made it more difficult by removing the event descriptions from the reports. Contact your US representatives and the FDA [1-888-463-6332] and let them know that this is NOT OKAY.

Here are some FDA MAUDE site reports that I have in my files.

Hypersensitivity reaction, tightness in knee. Information was received in 2005 from a pt's family member regarding a pt with a history of osteoarthritis who experienced tightness in the knee and hives at various places on pt's body, some bruising, difficulty breathing and an allergic reaction to synvisc. The pt began treatment with synvisc in 2005. The pt received a series of three synvisc injections into the right knee in 2005. During the first week of the following month; the pt began to experience hives at various places on their body, and some bruising. The hives were treated with benadryl 50 mg tid and hydrocortisone cream. The treatment helped, but the hives came back if therapy was interrupted. The severity of hives had gotten progressively worse and during that same month the pt experienced difficulty breathing and went to the emergency room (er). Pt were placed on zyrtec (dose unknown) qd, prednisone 60mg as a single dose in the er and prednisone taper starting the following day at 40mg x 4 days, 30mg x 4 days, 20mg x 4 days, 10mg x 4 days, then discontinue. The pt was also prescribed pepcid (dose unknown) for stomach upset associated with prednisone. The pt's discharge diagnosis from the er was "allergic reaction to synvisc". In addition, the pt experienced "tightness in the knee" after each synvisc injection. At the time of this report, the pt's outcome was unknonw. Additional information was received in june 2005 from the pt's family member. The pt has a history of an allergy to feathers. In may 2005 the pt experienced swelling of their lips and chest tightness while being tapered off of the zyrtec tto allow allergy skin testing ("the pt needs to be off zyrtec for 4 days to allow allergy skin testing"). On an unknown date, the pt re-restarted their zyrtec 10 mg daily and the swelling on the lips and the chest tightness resolved. The pt was switched to benadryl 50 mg because they only had to be off of the benadryl for two days before skin testing could be done. In june 2005, approximately twelve hours after the last dose of benadryl the pt experienced face and lips swelling and hives cover every part of their body. Their lips "became so swollen the lips split. " on unknown date, the pt was seen in the er where they received solu-medrol by injection, benadryl by injection, prednisone and zyrtec. At the time of this report, the hives and swelling resolved. Additional information was received in june 2005 from a pt's family member who reported that the pt had a history of hypothyroidism, asthma and allergies. Family member stated that the pt's reaction was worsening, as they broke out in hives again that morning. She stated that the pt experienced bruising at times, after the rash and subsided. She noted that the allergist/hcps have hypothesized that the bruising occurs due to increased capillary perfusion subsequent to the rash. Family member stated that the pt was on prednisone and an antihistamine and was still experiencing the reactions. The pt was going to see an allergist the day of the call, but on previous attempts to taper the steroid/antihistoamine the reactions had reappeared and the allergy testing could not continue. The allergist was of the opinion that the reactions, because they were delayed, were not likely caused by synvisc. The allergist was checking to determine other possible causes. Additional information was also received in june 2005 from the pt. The pt confirmed they had a history of allergy to feathers, but they could eat eggs. The pt stated they had to go to er in 2005 because their lips were so swollen that they cracked and started to bleed, their face swelled, their eyes swelled and they had welts over their body with bruising. They stated that the reactions were getting worse over time.
