Yes, it is entirely safe to continue taking your Thyronorm 50 (levothyroxine) on the day of your Covishield vaccine and the days following. Levothyroxine simply replaces a hormone your body needs and does not interfere with how the vaccine works or increase any risks. Having had a COVID-19 infection in December also does not affect this; in fact, getting vaccinated helps protect you further. Please do not skip your thyroid medication, as maintaining stable thyroid levels is important for your overall health.

An elevated total T4 of 16.2 ?g/dL while on levothyroxine (Thyronorm) is actually quite common and usually not a cause for concern. Since levothyroxine is T4, taking your medication shortly before your blood test can temporarily raise this level. Additionally, natural proteins in your blood can sometimes elevate total T4. As a next step, please consult your doctor. They may suggest testing your 'free T4' level, which is a more accurate measure, to confirm everything is perfectly on track.

Managing your thyroid health postpartum is very important. Since you started levothyroxine (Thyronorm) during pregnancy, your doctor will likely adjust your dose downward or reassess if you still need it, as thyroid demands decrease after delivery. This is typically checked 6 to 8 weeks postpartum. You should not stop your daily medication in the days leading up to your thyroid test, as this can skew the results. However, on the morning of your blood draw, simply wait to take your daily dose until after your blood is taken. Please consult your doctor for your specific plan.

Thyronorm (levothyroxine) is indeed the correct medicine to help treat this. However, experiencing a pounding heart and severe nausea can suggest that your current dose of 88 mcg might be a bit too high for your body right now. Please don't worry, but I highly recommend reaching out to your doctor promptly. They can easily review your symptoms, perhaps recheck your blood levels, and safely adjust your dose so you can start feeling much more comfortable and like yourself again very soon.

To determine if your Thyronorm (levothyroxine) 100 mcg dose is still right for you, your doctor will primarily rely on a simple blood test called a Thyroid Stimulating Hormone (TSH) test, sometimes alongside a Free T4 test. This is typically checked once a year when you are stable. Your doctor will also check how you are feeling, looking for symptoms like fatigue, weight changes, or feeling cold. Please share any changes you have noticed with your doctor; a simple, safe adjustment to your dose can easily be made if needed to keep you feeling your best.

Since your thyroid blood tests are still high, it indicates that your body is not getting enough thyroid hormone, which slows down your metabolism and leads to weight gain. Your daily thyroid medication, such as levothyroxine, likely needs a small dose adjustment. I highly recommend discussing these recent test results with your doctor soon. They can safely adjust your dosage to help bring your hormone levels back into balance and get your metabolism back on track.
