It is very common to feel concerned when seeing elevated blood test results like D-dimer. In patients recovering from COVID-19, especially after completing a steroid like Predmet (methylprednisolone), an elevated D-dimer can indeed signal an increased risk of blood clots. Doctors frequently prescribe blood-thinning medications (anticoagulants) in these situations to help prevent clots from forming. However, starting these medications requires a careful evaluation of his overall health and potential bleeding risks. Please share these results with his healthcare provider right away so they can safely decide if a blood thinner is appropriate for him.

Your symptoms are highly unlikely to be 'black fungus' (mucormycosis). This rare infection typically affects individuals with severely compromised immune systems or those on high-dose steroids for a long time. Predmet 4 (methylprednisolone) is a very low-dose steroid. Your stuffy nose and cheek rashes are much more likely due to a mild allergic reaction, skin sensitivity, or your body recovering from the infection. I highly recommend discussing these symptoms with your doctor so they can examine.

Your current regimen of Predmet (methylprednisolone) and Eliquis (apixaban) is appropriate for post-hospitalization recovery to manage inflammation and prevent blood clots. It is crucial to take these exactly as prescribed; do not stop Predmet suddenly, as it requires gradual tapering under your doctors guidance. Since you are recovering well and are symptom-free, a repeat COVID-19 test is generally not necessary, as tests can detect inactive virus for weeks. Continue resting, monitoring your oxygen, and follow up with your treating physician.

Please do not increase your dose of Predmet (methylprednisolone) on your own. Corticosteroids must be carefully managed by a doctor. Taking a higher dose without medical guidance can lead to unwanted side effects and may even delay your recovery. It is important to continue with the prescribed 8 mg once daily and immediately consult your healthcare provider if your fever or cough worsens. They can safely evaluate your lung scan and adjust your treatment if needed. Please rest, stay hydrated, and monitor your oxygen levels.

A D-dimer level of 710 is mildly elevated, which is quite common during recovery from COVID-19 and does not automatically mean he has a blood clot or needs blood thinners. Since he is recovering, his doctor will look at his overall risk factors, mobility, and any symptoms like leg swelling or shortness of breath before deciding on blood thinners. Please share these results with his treating physician promptly so they can safely guide his next steps. He is making good progress with his inflammation settling down.

Your father's oxygen levels of 85-86% and breathlessness when talking or walking are clear signs that he requires immediate hospital evaluation and oxygen therapy. While lying on his stomach helps temporarily, it is not a substitute for professional medical care, especially given his history of diabetes and COVID-19. Please take him to the nearest hospital or contact emergency services right away. You should continue his current medications, Predmet (methylprednisolone) and aspirin, exactly as prescribed until the hospital doctors review his treatment. Prompt medical care will ensure he gets the right support to recover safely.
