Could you help me understand if a normal chest X-ray taken two months after being around someone with TB means I definitely don't have pulmonary TB? Also, can a chest X-ray reliably catch pulmonary TB, or should I be doing other tests? I'm a bit worried and just want to be sure.

  1. Understanding Chest X-ray Limitations

    • A normal chest X-ray is reassuring but does not completely rule out pulmonary TB, especially in early or latent stages.
  2. Role of Additional Tests

    • Consider sputum smear microscopy, culture tests, and molecular tests (e.g., GeneXpert) for more definitive detection of active TB.
  3. Latent vs Active TB

    • Latent TB may not show on X-ray, unlike active TB, which often presents with visible abnormalities.
  4. Follow-up Recommendations

    • Monitor symptoms and repeat tests if symptoms develop. Consult a healthcare provider for tailored advice.
  5. Importance of Medical Evaluation

    • Professional evaluation is crucial, especially after recent exposure, to decide on preventive therapy or further investigations.
  6. Relevant Medical Specialties

    • Consult with pulmonologists or infectious disease specialists for a comprehensive assessment.
  7. Summary

    • While a normal X-ray is a good sign, further tests may be needed to definitively rule out TB.

I've been dealing with wheezing and a cold since last night. I took azithromycin 500 and a tablet with serratiopeptidase and diclofenac sodium, but now the wheezing has gotten worse. Should I consider taking methylprednisolone to help with the wheezing?

I'm really concerned about my mom's asthma. The doctor recommended Xanilax SR 200 instead of Theoasthalin SR, but I'm not sure if this is the right choice. Plus, it's a bit pricey. Could you give me some advice on whether Xanilax SR 200 is a good substitute?

Yes, Xanilax SR 200 is a suitable substitute for Theoasthalin SR in the treatment of Asthma. Xanilax SR 200 contains Theophylline which helps in relaxing the muscles in the airways, making it easier to breathe. As for the cost, Xanilax SR 200 may be slightly more expensive than Theoasthalin SR, but it is important to follow your doctor's prescription for optimal management of Asthma symptoms. The usual dosage of Xanilax SR 200 is 200mg once daily, but please follow your doctor's instructions for the correct dosage based on your mother's condition.

I'm really worried about my dad who's 73. He was diagnosed with COVID-19 on June 14th and had a mild fever, but that went away after taking paracetamol. Now he's started coughing since yesterday and while we're giving him Reswas syrup, it hasn't completely stopped. His D-dimer is 0.87 and CRP 9.6. Should we be concerned about these numbers? Is there anything else we should be doing or any other meds he might need?

continue the treatment add dextromethrophen syrup
