Providence Patient
Dr. Rediker was great at talking with me about my use of Eliquis. Dr. Schiffman said he called both Dr. Rediker and Dr. Cheng, hemattologist, about the dosage of Eliquis. Dr. Schiffman indicated he wanted me to reduce my dosage to 2.5mg for a year and eventually go off of it. Dr.Cheng said there was no one reason he could identify as to why I ended up in Mission's ER with multiple blood clots in both lungs and I should continue to take 5 mg of Eliquis. Dr. Rediker told me if it was him he would continue on the 5mg since there was no causative reason that could be identified for the blood clots. He recommended I see Dr. Cheng again to get his in person reasoning for the amount of Eliquis I should be taking. Since Dr. Rediker is retiring in December, I am making an appointment to see Dr. Cheng in early 2025.Dr. Rediker is a great doctor and someone easy to understand re medical issues.

Providence Patient
Dr. Rediker's office staff and nurse are just awesome. His nurse took the time to explain what was in my chart....took the time to tell me what my blood pressure was (it was good) and then when Dr. Rediker would be in to see me. Whe whole experience was great. Dr. Rediker was the physician who found blood clots in both my lungs a year ago and then told me I had to go to Mission Hospital asap for the clots. He is a very caring awesome doctor just as my rheumatologist, Dr. Mark Jason, was before he retired in 2022. He told me to continue to take Eliquis ([ID]mg) on the basis of 2x a day, which was in agreement with Dr. Cheng (hematologist I saw) but in contrast to what Dr. Schiffman had suggested in May. I appreciated his explanation for his recommendation.
