Cough and fever for a few days are often due to an infection, but taking multiple medicines together should be carefully monitored. Since you are already on Thyronorm and have a sulpha allergy, it is important not to add or change medicines on your own. Continue resting, stay well hydrated and take light meals to support recovery. Watch for symptoms such as an increasing fever, breathing difficulty, or weakness. Consult your doctor to review your current treatment and ensure it is safe and appropriate for you.

A TSH of 0.05 suggests that your current Thyronorm 75 dose may be too high. You should consult your doctor for dose adjustment, as thyroid medicine often needs reduction after pregnancy and regular monitoring to keep TSH within a healthy range.

It is unlikely that pure paracetamol caused your increased heart rate. However, many cold remedies combine paracetamol with decongestants (like pseudoephedrine or phenylephrine). These decongestants can interact with your thyroid medication (Thyronorm), causing a rapid heart rate. This reaction is usually temporary and not dangerous, but you should stop taking that medication. Please check the ingredient label. For safe cold relief, you can take plain paracetamol, use saline nasal sprays, or try steam inhalation. Avoid multi-symptom cold products containing decongestants. If your rapid heart rate persists or you feel dizzy, please consult your doctor.

The appropriate dosage of thyroid medication, such as levothyroxine (75 mcg), should be determined by your healthcare provider based on your individual TSH levels, overall thyroid function, and any other medical conditions you may have. A TSH level of 14.4 suggests hypothyroidism, meaning your thyroid may not be producing enough hormone. However, the exact dosage needs to be tailored to your specific needs. It’s essential to consult your doctor for a proper evaluation and to determine the right dosage for you. Do not self-medicate or adjust your dosage without professional guidance.
