Common use
Synthroid, known generically as levothyroxine sodium, is a man-made thyroid hormone (T4) designed to replace or supplement the natural hormone normally produced by the thyroid gland. It is commonly used to treat hypothyroidism, a condition marked by underactive thyroid function.
This medication supports metabolism, energy production, temperature regulation, and overall hormonal balance. It may also be prescribed for the management of goiter or to support treatment after thyroid cancer.
Dosage and direction
Synthroid is typically taken once daily in the morning, 30-60 minutes before eating, with a full glass of water. It must be taken on an empty stomach for optimal absorption.
Your dose will depend on your thyroid hormone levels, age, body weight, and individual response. Starting doses often range from 25 to 100 micrograms (mcg) per day, with adjustments based on regular blood test results.
Do not split, crush, or chew the tablet unless your healthcare provider advises otherwise.
Precautions
Before beginning Synthroid, inform your doctor if you have a history of:
• Cardiovascular disease (e.g., angina or heart attack)
• Diabetes or blood sugar imbalances
• Bone loss (osteoporosis)
• Adrenal gland issues
• Recent surgery or severe infections
Older adults and pregnant patients may require special monitoring. Consistency in the time of day and method of administration is essential for stable hormone levels.
Contraindications
Avoid using Synthroid if you:
• Are allergic to levothyroxine
• Suffer from untreated thyrotoxicosis (overactive thyroid)
• Have uncorrected adrenal insufficiency
• Are recovering from a heart attack (myocardial infarction)
This drug should never be used for weight loss or enhancing athletic performance, as misuse can lead to serious health risks.
Possible side effects
If your dosage is too high, you may experience signs of hyperthyroidism, such as:
• Chest discomfort or irregular heartbeat
• Anxiety, tremors, or irritability
• Sweating and heat intolerance
• Temporary hair thinning (more common in children or during dose adjustment)
Rare but serious side effects include seizures, severe muscle weakness, or signs of allergic reaction. Seek medical attention for any concerning symptoms.
Drug interactions
Some substances can interfere with Synthroid's absorption or effectiveness, including:
• Iron or calcium supplements
• Antacids or acid reducers (aluminum/magnesium)
• Blood thinners such as warfarin
• Medications for diabetes
• Certain antidepressants
Be sure to take Synthroid at least 4 hours apart from supplements containing minerals like iron or calcium.
Missed dose
If you forget to take a dose, take it as soon as you remember. If it is close to your next scheduled dose, skip the missed one. Never double your dosage to compensate.
Overdose
Overdosing on Synthroid can result in serious complications, including rapid heartbeat, chest pain, disorientation, seizures, or coma. If overdose is suspected, seek immediate emergency help.
Storage
Keep Synthroid in its original packaging at room temperature (68°-77°;F / 20°-25°;C). Store it in a dry location, away from direct heat, light, and humidity. Ensure it is safely stored away from children and pets.
U.S. Sale and Prescription Policy
In the United States, Synthroid is a prescription-only medication, authorized by the FDA for managing thyroid hormone deficiencies.
A valid prescription from a licensed medical provider is typically required to purchase it legally through most U.S. pharmacies. Patients usually undergo routine lab monitoring to ensure the proper dose is maintained.
However, Home Care Pharmacy offers qualified patients an alternative route to obtain Synthroid without a traditional prescription, through a pharmacist-assisted consultation in certain regions. This service is designed for convenience while still ensuring medical safety and compliance with local laws.
