What Is Levothyroxine Sodium?
Levothyroxine is primarily used to treat hypothyroidism, a condition where the thyroid gland produces an insufficient amount of thyroid hormones.
These hormones are essential for regulating the body’s metabolism and ensuring that various bodily functions, including energy production and growth, occur efficiently. Levothyroxine supplements these hormones, restoring normal body functions.
In addition to its primary use in hypothyroidism, Levothyroxine may also be prescribed for the treatment of other thyroid-related diseases, including thyroid cancer.
However, it is not intended for weight management unless the individual’s weight issues are directly linked to a thyroid deficiency.

Correct Way to Use Levothyroxine Sodium
Dosage Instructions
Levothyroxine is usually taken once a day, on an empty stomach, to enhance absorption. It is best consumed 30 minutes to an hour before breakfast with a full glass of water. Always follow the dosage instructions provided by your healthcare provider. If you are using the capsule form, swallow it whole—do not chew or break it.
Dosage Adjustment for Children
If a child or infant has difficulty swallowing the tablet form, consult your healthcare provider for guidance. For children who cannot swallow whole tablets, the medication can be crushed and mixed with a small amount of water and taken immediately.
Potential Side Effects
Like all medications, Levothyroxine may cause side effects. The severity and frequency of these effects vary from person to person. Below are some possible side effects:
Common Side Effects
- Temporary hair loss (especially in the first few months)
- Sensitivity to heat and excessive sweating
- Fatigue or lethargy
- Weight fluctuations
- Mood swings or nervousness
Serious Side Effects
While rare, some people may experience severe reactions. Seek immediate medical help if you notice any of the following:
- Chest pain or tightness
- Heart palpitations or irregular heartbeat
- Severe dizziness or fainting
- Difficulty breathing
- Extreme allergic reactions, including swelling, rash, or trouble breathing
Special Precautions Before Using Levothyroxine
Levothyroxine is a safe and effective medication when used properly. However, certain precautions should be taken, especially if you have specific medical conditions or are taking other medications.
Conditions to Be Aware Of
Before using Levothyroxine, disclose any pre-existing medical conditions to your healthcare provider, especially:
- Heart-related problems, such as high blood pressure or arrhythmias
- Adrenal gland issues
- Diabetes (as this medication can affect blood sugar levels)
- Any history of thyroid dysfunction or overactive thyroid (hyperthyroidism)
Potential Risks for Specific Populations
- Pregnant Women: Levothyroxine is generally safe during pregnancy, but the dosage may need to be adjusted as your body’s thyroid needs change.
- Elderly: Older adults may experience more significant side effects related to the heart and thyroid, necessitating closer monitoring and possible dose adjustments.
- Children: While Levothyroxine is safe for children, it is essential to ensure that their growth and development are properly monitored, as prolonged treatment could impact their skeletal growth.
Drug Interactions to Watch For
Levothyroxine may interact with various medications, altering its effectiveness or raising the risk of adverse reactions. Some medications that can interfere with Levothyroxine include:
- Iron supplements
- Calcium-based products
- Cholesterol-lowering drugs
- Certain antacids or stomach acid reducers
Ensure your healthcare provider is aware of all medications you are currently taking, including over-the-counter drugs, herbal supplements, and any other prescribed treatments. This will help minimize the risk of drug interactions.
Overdose Symptoms and What to Do
In the event of an overdose, it is critical to seek immediate medical assistance. Symptoms of overdose may include:
- Rapid heart rate or irregular pulse
- Confusion or disorientation
- Severe dizziness
- Seizures
If you suspect an overdose, contact your local poison control center or seek emergency help right away.
Proper Storage and Handling of Levothyroxine
Levothyroxine should be stored in a cool, dry place away from direct sunlight. Do not store it in the bathroom, where humidity may affect the medication.
Always ensure the medication is out of reach of children to prevent accidental ingestion.
If the medication is past its expiration date or no longer needed, consult your pharmacist or local disposal facility for proper disposal methods. Avoid flushing the medication down the toilet or throwing it in the trash unless specifically instructed.
Conclusion
Levothyroxine Sodium is an effective treatment for managing hypothyroidism and maintaining balanced thyroid hormone levels. While it can significantly improve health and vitality in individuals with thyroid disorders, it is essential to follow prescribed dosages, adhere to safety precautions, and consult your healthcare provider for regular monitoring.
Although side effects are generally rare and manageable, staying informed about possible risks and maintaining communication with your doctor ensures the medication’s effectiveness and your overall well-being.
