Is there a lawsuit for lisinopril

Thank you to everyone who reads through this complex case. I have a 66 year old senior family member who was diagnosed earlier this year with a rare autoimmune disorder known as Statin-Associated Necrotizing Autoimmune Myositis, caused by the cholesterol drug Lisinopril by Pfizer.
His symptoms began back in April of 2019 when he began feeling general weakness, especially in his extremities and legs. His urine began to turn darker, almost cola-brown which we later determined is called rhabdomyolysis, caused by the myositis. This results from the death of muscle fibers and release of their contents into the bloodstream. It can lead to serious complications such as renal (kidney) failure. He was initially diagnosed by his doctor (over the phone I believe) with lyme disease which he has had in the past. When the prescribed doxycycline didn’t cause any improvement he was taken to the hospital in June where he was diagnosed by a rheumatologist with dermatomyositis due to the severe muscle weakness, a skin rash on the upper chest, and eyelid redness. He spent 8 days there receiving methotrexate (a chemotherapy drug) and corticosteroids. After a few more weeks of further degradation he went to a skilled nursing facility (nursing home) for additional full-time care and physical therapy. At this point he had to be picked up to be maneuvered, use the bathroom, etc. He was also in severe physical pain, especially when attempting to bear any weight such as attempting to use a walker. He was in this facility for 5 days in July but they clearly could not handle him as a patient in his condition. Their staff was not trained for this level of care, they couldn’t properly use the Hoyer lift to maneuver him, etc. He was then taken in mid-July to another rheumatologist office that came highly recommended for a second opinion. This office was part of a much larger hospital and network. This doctor within just a few minutes of seeing him and reviewing his symptoms advised us that he is in need of extreme care, much more intense chemotherapy treatment, and he should be admitted into the hospital immediately. At this point he had degraded to the point of barely being able to eat, not being able to stay sitting up on his own or hold his own head up. He was completely bound to either a bed or a wheelchair. We brought him directly from the doctor’s office to the larger more well-known hospital nearby and she alerted them that he was coming and needed immediate care. He spent the next ~50+ days in the hospital getting several bouts of more intense chemotherapy including two rounds of Rituximab and Cyclophosphamide as well as high dose corticosteroids. He was in the ICU on multiple occasions due to his blood pressure dropping to critical levels (several rapids were called), bacterial pneumonia most likely due to mucus aspiration, and being put on a ventilator when he was unable to breathe. He eventually lost his ability to speak for unknown reasons (perhaps related to throat muscle issues). He had a nasal feeding tube for several weeks which was eventually switched to a PEG feeding tube through the stomach/abdomen wall. He had two moderately bad bed sores during this entire stay that he continues to still have one of today and he experienced an injury when his leg fell from the Hoyer lift causing internal bleeding and significant blood loss. He has over a half-dozen total blood transfusions. He also had a tracheostomy placed in his neck to aid with breathing and mucus removal. Eventually he started progressing in the right direction and was having less complications. The hospital said they wanted to discharge him with the reason being that he now needed extensive physical therapy (3+ hours per day) which only two facilities in the state could offer. After touring both facilities it was clear that one was better suited and the other had a “hard 30-day limit” for patients. The plan was to have him stay in their medical rehab center for the extensive therapy necessary. He was admitted to that facility directly from the ICU in mid-September and went straight to their COU (Close Observation Unit). I believe this was due to having the tracheostomy in and needing respiratory therapists available. He spent the next two months being treated as essentially a hospital patient, receiving very minimal rehab for only a few minutes once per day and not on weekends. He never received any of the 3 hour extensive rehab he was assured he would get there. He still hasn’t made it out of the Close Observation Unit to the medical rehab area where he was originally supposed to go. They were finally able to remove the trach a few days ago and he has begun a bit more physical therapy. He is using specialized rehab equipment with great progress each day. The facility (specifically a social workecase coordinator there) has been attempting for several weeks to push him out to a lower level skilled nursing facility with their claim being that his insurance (a medicare plan but with a traditional provider backing it, so apparently not “true” medicare) will soon deny coverage. When we contact his insurance company to discuss this they tell us we are “calling too early and they haven’t denied coverage so we have nothing to worry about.” They say that it is the rehab facility pushing him out and not the insurance company. The facility says it is the insurance company that will soon be denying coverage. The main nurse in the Close Observation Unit who oversees him stated that she thinks he is making great progress and that she would like to keep him there as long as possible but she’s “seen this before and the insurance company is going to soon deny coverage”. They say that legally they cannot make any recommendations of other facilities. The only way to find/choose a different facility is to go through the list of covered facilities in the state and to contact them one-by-one and to take time off from work to tour them. He was already in a skilled nursing facility as mentioned previously when he had even more mobility than he does now and before his condition became more severe. Even at that point in time the skilled nursing facility could not care for him. We have contacted a few other facilities but found out that they are not suitable for a variety of reasons including but not limited to: A. They stated based on the patient’s described condition they cannot care for him. B. Many don’t have any of the specialized equipment that he’s currently using including Encore walkers that are greatly aiding in his recovery. C. They do not offer extensive physical therapy. Several other facilities were contacted over a week ago with no callback.
We are unsure what to do next. He is finally making great progress where he is within the last week. He has begun more regular therapy and had the trach removed. Now they are attempting to push him out as soon as things are going well. We were told months ago that this was the best facility in the state and one of only two that could help him with the quality of therapy needed which he has only just begun receiving. We’re told that once they deny coverage we can file an appeal but if the appeal is ultimately denied we will be on the hook for the bill that could range into tens of thousands of dollars, potentially bankrupting my family. Now that the trach was removed last week the day before Thanksgiving we are expecting them to call again tomorrow asking for the millionth time if we have “found a new place” for him. We believe they will attempt to push him out as soon as tomorrow (Monday December 3rd) unless we file an appeal.
Financially it appears most everything has been covered so far after receiving some sort of separate medical card via the state. On a bit of a separate note we contacted an attorney several weeks ago who came highly recommended to discuss the possibility of a lawsuit against the pharmaceutical company (Pfizer). He ultimately turned it down stating it is too big a case for him to take on. We are located in the US btw.
Any thoughts, advice, references, or recommendations would be GREATLY appreciated. We have no idea if we should risk fighting to have him stay in his current facility where he is finally making good progress. They are pressuring us heavily to put him in a different lower level facility. We think he should stay where he is since this facility came highly recommended from all of the physical therapists at the hospital and everyone we spoke to. They said it is THE place for him to recover from this rare disorder. Now they are attempting to push him out just as he is beginning to get the therapy he was initially promised.
