The response shows that the thyroid medicine is doing its job perfectly. As the levels TSH has been down significantly, you may take consultation as to step down the dosage of medication to a lower dose gradually over a period of time.

When to stop levothyroxine?
In most adults, thyroid hormone replacement is not stopped just because TSH improves — improvement usually means the drug is correcting the deficiency, not that the thyroid has recovered.
Stopping is considered only in specific situations:
Possible to attempt stopping (doctor-supervised trial) if:
• Hypothyroidism was temporary (e.g., thyroiditis, postpartum thyroiditis, drug-induced)
• Mild subclinical hypothyroidism and symptoms absent
• Low antibody levels (anti-TPO negative)
• Low dose requirement and stable labs for months
Usually lifelong treatment if:
• Initial TSH was very high (like 32)
• Autoimmune thyroid disease (Hashimoto’s)
• Symptoms were present
• Thyroid gland damage or surgery history
What is typically done now
Since TSH is still above ideal target (generally ~0.5–3.5 for treated patients):
Continue current dose
Recheck TSH 6–8 weeks after any dose change
Adjust dose if needed
Only consider dose reduction after stable normal TSH for several months

Dear Patient,
Your sister initially had TSH 32, which clearly indicates hypothyroidism. After starting Thyronorm 75 mcg, her TSH has come down gradually to 4.09, which means the medicine is working and thyroid levels are improving.
she should NOT stop Thyronorm suddenly.
Hypothyroidism treatment is usually long-term (often lifelong), especially when initial TSH was very high like 32.
Current TSH 4.09 is slightly toward the upper normal range. Ideal target TSH in treated patients is usually around 1–3 (especially in young females).
Continue Thyronorm 75 mcg and repeat TSH after 6–8 weeks
Dose adjustment may be needed depending on symptoms and weight
Dose reduction or stopping is only considered if: • TSH becomes very low (<0.5)
• Symptoms of excess thyroid appear (palpitations, weight loss, tremors)
Important
• Take tablet empty stomach morning, 30–45 minutes before food
• Do not miss doses
• Avoid calcium/iron within 4 hours of medicine
Repeat TSH after 6–8 weeks on same dose before making changes.
Stopping medicine can cause: • Fatigue
• Weight gain
• Hair fall
• Irregular periods
• Cholesterol increase
So please do not stop without medical advice.
For proper dose adjustment based on weight, symptoms, and reports, you should consult me directly on Practo or text me there, because thyroid treatment needs personalized monitoring to avoid future complications.
