Levothyroxine Dosage

If you happen to suffer from hypothyroidism, chances are that you were prescribed a certain Levothyroxine dosage. Levothyroxine is a drug that is often prescribed for patients who suffer from thyroid related issues. If you or someone you know happens to have an inactive thyroid, chances are that they have been put on the drug. Many specialists also recommend Levothyroxine off-label in order to treat patients who might not suffer from the condition especially those who suffer from depression.

 

Dosage

There is no standard dosage for the drug simply because the patients for whom it is prescribed for suffer from varying levels of hypothyroidism or some other thyroid related conditions. Dosages also vary according to how a patient’s body reacts to the drug and is thereby administered accordingly. In general, a Levothyroxine dosage usually does not exceed more than 200 mcg per day.

 

Adult Dosage for Hypothyroidism

The medication itself is usually taken either as a pill or a gel once every morning. The initial dose for adults ranges from 12.5 to 50mcg per day. Intake might be adjusted or increased from 12.5 to 2.5 mcg per every two to four weeks.  Whatever dosage the doctor prescribes make sure that you take it at the same time every day. This will help your body regulate the drug throughout your bloodstream more effectively.

Your dosage will also depend on medical tests. For example, your health care provider will adjust your Levothyroxine dosage according to your blood tests. This is also why you must ensure that you inform your health care provider if you happen to miss any of the dosages. In such cases, the medical specialist will need to re-adjust the level of the dose.

Taking the medication on a full stomach is not advisable. If you have already had breakfast, make sure that you wait 40 to 60 minutes before taking the prescribed dose. In fact, in order to maximize the effects of Levothyroxine you can take it –

  • With water
  • An hour before taking any other medication, vitamin or supplement
  • Two hours before iron or calcium intake.

 

It is not advisable to administer large doses of Levothyroxine in patients who are prone to concomitant heart disease. However, a smaller dosage is no cause for concern. Doctors usually double up the dosage if a patient happens to miss one. In other words, the dose is increased as much as your body needs to catch up.

The medication is crushed or mixed with water when it comes to young children. However, when it comes to infants the dosage is as low as 5mcg/dL.

Also make sure that you do your research before taking any other forms of medication along with the drug. For example, there is certain nonprescription flu medication that should not be taken with Levothyroxine. The same is the case with some over the counter drugs, especially those that contain iodine or the thyroid hormone. These have the propensity to compromise your Levothyroxine dosage and should be given a wide berth.
