Your Synthroid dosage is personalized. Never adjust it without your doctor’s guidance. Typical starting doses range from 25 to 100 mcg daily, adjusted based on your blood tests and response.
Regular blood tests monitor your thyroid hormone levels (TSH, T3, T4), ensuring your dose remains optimal. These tests guide dosage adjustments for best results.
- Too low a dose: You may experience persistent fatigue, weight gain, constipation, cold intolerance, and dry skin. Too high a dose: You may experience rapid or irregular heartbeat, anxiety, tremors, insomnia, weight loss, and heat intolerance.
Common side effects, generally mild, include:
- Headache Nausea Constipation or diarrhea Muscle aches Changes in menstrual periods
These usually subside as your body adjusts to the medication. Severe or persistent side effects require immediate medical attention.
Report any new or worsening symptoms to your doctor. Take Synthroid on an empty stomach, at least 30 minutes before breakfast, for optimal absorption. Maintain consistent timing of your daily dose. Avoid calcium and iron supplements within four hours of taking Synthroid. Inform your doctor about all medications and supplements you use.
Remember, open communication with your doctor is key to managing your thyroid condition effectively.
