I have some very reassuring news: your thyroid test results are all within the normal, healthy range. This means your current daily dose of 25 mcg of levothyroxine is working beautifully, and no adjustment is needed right now. Additionally, there is no known major interaction between levothyroxine and flunarizine, so using it for your migraines will not impact your thyroid management. Please continue taking both medications as prescribed and keep up with your routine checkups.

Since your TSH is still 7 mIU/L, your current levothyroxine (Thyronorm) dose of 25 mcg may be too low and might need to be adjusted by your doctor. Additionally, progressive weight loss to 37 kg is atypical for hypothyroidism and requires careful evaluation. I highly recommend visiting your healthcare provider soon. They can discuss adjusting your levothyroxine dose and run tests to check for nutritional deficiencies, iron levels, or absorption issues that could be causing these symptoms.

Since these itchy, acne-like patches on your forehead haven't responded to adapalene or Clearz Plus, and given your PCOD, this might not be typical acne. The itchiness strongly suggests a condition called fungal folliculitis (an overgrowth of natural yeast), which mimics acne but requires antifungals rather than standard acne topicals. Hormonal fluctuations can also contribute. I gently recommend consulting a dermatologist to confirm this. They may suggest a topical antifungal like ketoconazole, which is safe to use alongside your metformin and levothyroxine.

A TSH level of 13 indicates your body is lacking essential thyroid hormone. The most reliable way to normalize your thyroid and regulate your periods is to restart your prescribed levothyroxine (Thyronorm 75 mcg). Alternative therapies unfortunately cannot replace this vital hormone. I highly recommend consulting your doctor to safely restart your medication. They will monitor your blood levels in a few weeks to ensure your dosage is perfect.

For regular check-ups while taking Thyronorm (levothyroxine) 75 mcg daily, you should consult either an endocrinologist (a hormone specialist) or a general physician. Both can comfortably manage your routine monitoring. I suggest getting a fresh Thyroid Function Test (TSH, Free T3, Free T4) blood test done just before your visit so the doctor has the latest updates to review your dosage. Please continue taking your medication daily as prescribed.

Your TSH of 5.9 suggests your Thyronorm (levothyroxine) dose may need a slight adjustment. Regarding Ayurvedic or homeopathic remedies, please avoid adding them without consulting your doctor. Combining these with your current thyroid, depression, and breathing medications can cause harmful drug interactions. Additionally, a vegetarian diet is not universally mandatory for Ayurvedic treatments. Please share these symptoms with your doctor; adjusting your current prescription is the safest way.
