Drugs Home > Levoxyl Dosage

There is no standard dosage for Levoxyl. Because there are varying degrees of hypothyroidism and other thyroid problems, the dose will vary from person to person. The guidelines your healthcare provider will follow will vary depending on things such as your age, the results of certain blood tests, and other medical conditions you may have.

An Overview of Levoxyl Dosing

The dose of Levoxyl® (levothyroxine sodium) that your healthcare provider recommends will vary depending on a number of factors, including:
  • The results of certain thyroid blood tests
  • Your age
  • Other medical conditions you may have
  • Any other medications you are taking.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.

Is There a "Standard" Dosage for Levoxyl?

There is no standard Levoxyl dose. Because people have varying degrees of hypothyroidism and other thyroid problems (and varying responses to medication), Levoxyl is not a "one-size-fits-all" medication. Instead, the dose 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, even if you have been stable for a while. It is important to understand that it can take a few weeks (or sometimes even a few months) for your body to adjust to any change in dose.
Some healthcare providers start at a higher Levoxyl dose and adjust as necessary, while others start at a low Levoxyl dose and slowly work up to the best dose. Either way, you will need frequent blood tests to monitor your thyroid function, and the results of these tests will guide your healthcare provider to make any necessary dosing adjustments.
Elderly people and people who have heart problems are usually started on lower doses, due to the risk of heart problems. A typical adult usually ends up taking Levoxyl 100 mcg to 125 mcg per day, although many people may need more or less. It is rare to need a dose higher than Levoxyl 200 mcg per day.
