Because there are varying degrees of hypothyroidism and other thyroid problems, the proper dosage of Synthroid will vary from person to person. The recommended dose will be based on factors such as your age, other medical conditions you have, and the results of certain blood tests. The medication comes in tablet form and is typically taken once a day in the morning.
An Introduction to Synthroid DosagesThe dosage of Synthroid® (levothyroxine sodium) your healthcare provider recommends will vary, depending on a number of factors, including:
- Your age
- Other medical conditions you may have
- The results of certain thyroid blood tests
- Any other medications you are taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
What Is the Recommended Dose of Synthroid?Because people have varying degrees of hypothyroidism and other thyroid problems, Synthroid is not a "one-size-fits-all" medication. Instead, the Synthroid dosage must be individualized. It often takes several months to find the best dose, and your dose may need to be adjusted from time to time.
Some healthcare providers start at a low Synthroid dosage and slowly work up to the best dose, while others start at a higher dose and adjust as necessary. You will need frequent blood tests to monitor your thyroid function, and the results of these tests will guide your healthcare provider in making any necessary dosing adjustments.
Elderly people and people with heart problems are usually started on lower dosages, due to the risk of heart problems. A typical adult usually ends up taking Synthroid 100 mcg to 125 mcg per day, although many people may need more or less. It is rare to need a dosage higher than Synthroid 200 mcg per day.
