Current Insights on Apixaban Dosage: Effectiveness and Safety
As a radiologist, I must admit this topic isn’t my primary area of expertise. However, I have some personal experience to share. I previously suffered from an unprovoked pulmonary embolism, and after thorough evaluations, including cancer screening and tests for other potential causes, nothing unusual was found. I am a 70-year-old non-smoker weighing 175 pounds. Following this, my hematologist recommended a dose of 5mg of apixaban twice daily. After six months, during a follow-up visit, I consulted her physician assistant about the possibility of reducing my dosage to 2.5mg twice a day. The assistant’s response was that taking a lower dose might compromise the medication’s effectiveness while carrying the same risks for side effects. I would appreciate any insights or recommendations on this matter.

Apixaban is an anticoagulant used to prevent blood clots, and the dosage can depend on multiple factors, including age, weight, kidney function, and the specific condition being treated. It's understandable to seek clarity on your dosage, especially after experiencing a significant health event like a pulmonary embolism.
Key Points
-
Standard Dosage: The standard starting dose for apixaban to prevent blood clots is typically 5 mg twice daily. In certain cases, like when the patient's renal function is compromised or if they are over a specific age, a lower dose of 2.5 mg twice daily may be appropriate.
-
Safety vs. Effectiveness: Reducing the dosage may potentially decrease the medication’s effectiveness, but it may also lower the risk of side effects. A healthcare professional can help weigh these aspects based on your specific health profile.
Considerations
- Your Health Profile: At 70 years old and with a history of a pulmonary embolism, you are on a critical path that requires careful monitoring. Since you are a non-smoker and have no other identified issues, this may positively influence your overall risk factors.
- Risks of Changing Dose: Lowering the dose can have implications, especially if you are at a higher risk for thrombosis due to your history of pulmonary embolism.
Recommended Next Steps
-
Discuss with Your Hematologist: Schedule a consultation with your hematologist to review your treatment plan. Discuss your concerns about dosage and the assistant's feedback. Key questions may include:
- What specific factors necessitate the higher dosage for your condition?
- What monitoring will be in place to assess the effectiveness of the medication if a dosage change occurs?
-
Monitor Side Effects and Efficacy: If you remain on the 5 mg dosage, pay attention to how you feel overall. Report any unusual side effects, and ask about the signs of potential complications due to increased anticoagulation.
-
Consider Regular Follow-ups: Regular check-ups (every few months) might help assess if the current dose is still appropriate based on any new health developments or changes in your overall health status.
-
Stay Informed: Educate yourself about apixaban and its function in your treatment plan. Knowledge about how it works and complications can empower you during discussions with your healthcare team.
If you have ongoing concerns, never hesitate to seek clarity or a second opinion to ensure your treatment aligns with your needs and health goals.

Understanding 'Reference Interval Not Established' in Blood Test Results
In my late 50s and measuring 5 feet 10 inches with some added weight, I recently came across my previous blood test results from a direct-to-consumer service conducted two years ago. As I prepare for another round of testing, I'm diving back into my earlier findings. Notably, four of the results from two years ago showed "Reference interval not established," yet I believe these figures hold some importance. For instance, online resources often indicate that having 10% Monocytes is considered elevated. At that time, I had a minor issue with my knee, which has since resolved. However, I'm planning to address my jock itch and incorporate antibacterial mouthwash into my routine for a week before my upcoming test. I'm curious to hear any insights regarding these results.
Concerns About Right Thigh Mass
A 37-year-old woman has recently begun a light exercise regimen following a pregnancy loss a few months back. After using the treadmill and elliptical just over a week ago, she observed a noticeable oblong mass on the front part of her upper right thigh the next day. The mass doesn't cause pain when touched; it feels firm yet has a bouncy quality. While the leg feels slightly unusual, leading her to suspect a possible strain, her mind is racing with anxiety over the possibility of it being a tumor affecting her nerves. After some extensive online research, she is considering whether this could be a lipoma, although she wonders why it has only now become apparent. The mass is roughly 4 to 5 inches in size and isn't very visible to others, as her husband can barely detect it, but she is acutely aware of its presence. With an appointment scheduled with her primary care physician next week, she finds herself feeling stressed about the situation. Furthermore, she's experiencing some sadness as she seeks to improve her health in hopes that she and her husband can attempt to conceive again soon.
Wrist Sprain Dilemma
28 years old About six weeks ago, I lost my footing on some ice and ended up spraining my wrist. The following day, concerned about the ongoing swelling, I visited an urgent care center. After they performed X-rays, I was reassured that there were no fractures, and the diagnosis was simply a severe sprain. I was advised to keep applying ice, use compression, and wear a wrap, with a recommendation to consult a specialist if the swelling persisted. Fortunately, the swelling subsided, so I figured a follow-up appointment wasn't necessary and that my wrist would improve with time. However, I've been experiencing ongoing discomfort, and this week the pain has intensified, despite the absence of any swelling. There’s noticeable shaking when I attempt to move my wrist side to side, and bending it downwards is quite challenging. Additionally, I'm feeling some unusual pain in my elbow, similar to striking my funny bone, along with tingling sensations in my hand. I keep hearing that sprains require considerable time to heal and can sometimes take several months. Is this something I should expect? I'm contemplating seeing a specialist, but since I haven’t met my deductible yet this year, I'm concerned the urgent care bill will already be a significant expense, making my deductible quite daunting to address all at once. Based on my symptoms, does this seem like normal healing, or could it indicate a more serious issue? I fear that I might have pinched a nerve, leading to an internal issue that’s hindering my ability to bend my wrist. Yet, I’m hesitant to rush into seeing a doctor if these symptoms simply reflect the typical recovery process for a sprain.
Unpleasant Taste in Mouth
Overview: 25-year-old male, quit smoking a month ago, underwent tonsillectomy as a child, and consumes alcohol infrequently. For the past three days, I've been experiencing an incredibly foul taste or odor whenever I swallow, whether I’m using a straw or not. I initially suspected a cavity might be responsible, but I’m starting to think differently as swishing water leaves no taste unless I swallow it. This unpleasant sensation doesn’t occur with every swallow; it tends to be most intense during the first few bites before gradually diminishing. I haven’t experienced any dental pain, nor do my gums seem irritated. There’s been no fever, and both my tongue and the interior of my mouth look entirely normal, leading me to rule out thrush. My wife mentioned that my breath smells fine. I did have some sniffles on the day this started, which I attribute to allergies related to my mother-in-law’s dog, and a bit of nasal congestion followed, but it was nothing severe. I tried performing a saline rinse on my sinuses, but nothing noteworthy came out. Gargling with salt water didn’t produce any positive results either. When I blow my nose, the mucus has no unusual or strong odor. This situation is incredibly frustrating. It feels akin to having something putrid lodged in my sinuses. Currently, I’m not taking any medications, though I do use a whey protein supplement and a pre-workout formula.
Received the MCV B Vaccine Twice
In October 2022, at the age of 20, I received the MCV B vaccine through my school rather than at a healthcare facility. Just last week, I found myself getting vaccinated a second time. This was because my doctor's office lacked the vaccination records from my school, and I mistakenly believed it was a different shot altogether. During this recent visit, I received both the MCV B vaccine and the booster simultaneously, with one injection in each arm. Overall, I felt okay post-vaccination, but the pain in my left arm (where I received the MCV B) was excruciating, causing me distress and tears for three consecutive days. Given that I usually have a high tolerance for pain, this reaction was quite significant for me. Although these vaccinations were spaced out over a couple of years, I’m curious if anyone is aware of any potential side effects or unusual outcomes that might arise from receiving the MCV B vaccine twice?
