Synthroid (levothyroxine sodium) is a synthetic form of the thyroid hormone thyroxine (T4), used to treat hypothyroidism—a condition where the thyroid gland does not produce enough hormones. It helps restore proper hormone levels, improving symptoms such as fatigue, weight gain, cold sensitivity, and slow metabolism. Synthroid is also used in the treatment and suppression of certain types of goiters and thyroid cancer. By replacing or supplementing the natural thyroid hormone, Synthroid plays a critical role in regulating the body’s metabolism and energy balance.
Synthroid should be taken orally once daily, ideally on an empty stomach, 30 to 60 minutes before breakfast, with a full glass of water. Dosage varies based on individual needs, age, weight, the severity of hypothyroidism, and other health factors. Most adults start at a low dose and increase gradually based on regular blood tests (TSH levels). Do not stop or change your dose without medical advice. Synthroid tablets should be swallowed whole and not split or crushed unless advised. Consistent daily use is important for effective therapy.
Before starting Synthroid, inform your doctor if you have any heart problems, diabetes, adrenal gland disorders, or a history of thyrotoxicosis. This medication may affect blood sugar levels, so diabetic patients should monitor glucose levels closely. Overuse or incorrect dosing can lead to symptoms of hyperthyroidism. Avoid taking calcium, iron, antacids, or certain cholesterol-lowering drugs within 4 hours of Synthroid, as they may interfere with absorption. Pregnancy and breastfeeding are generally safe with Synthroid, but dosage adjustments may be necessary.
Synthroid is contraindicated in patients with uncorrected adrenal insufficiency, untreated thyrotoxicosis, or those with a known hypersensitivity to levothyroxine or any inactive components. It should not be used as a weight loss aid, especially in individuals with normal thyroid function, due to serious or life-threatening effects when taken in high doses.
Most people tolerate Synthroid well when used as prescribed. However, side effects may occur if the dose is too high. These may include headache, nervousness, insomnia, sweating, heat intolerance, weight loss, increased appetite, tremors, and fast or irregular heartbeat. Long-term use at high doses may cause bone loss (osteoporosis), especially in women. If you experience chest pain, shortness of breath, or signs of severe allergic reaction (rash, itching, swelling), seek medical attention immediately.
Synthroid can interact with many medications, including blood thinners (like warfarin), insulin or oral diabetes medications, antidepressants, and seizure medications. Drugs containing calcium, magnesium, aluminum, or iron can reduce its absorption. To minimize interactions, take Synthroid at least 4 hours apart from these substances. Always inform your healthcare provider of all medications and supplements you are taking before starting or adjusting Synthroid.
If you miss a dose of Synthroid, take it as soon as you remember, unless it is close to the time of your next dose. Do not double the dose to make up for a missed one. If multiple doses are missed, consult your doctor to resume therapy safely. Consistency is key, so try to take Synthroid at the same time every day.
Symptoms of Synthroid overdose may resemble signs of hyperthyroidism and include rapid heartbeat, agitation, confusion, chest pain, or seizures. Long-term overdose can lead to heart complications or bone loss. In case of overdose, seek emergency medical attention. Treatment may include medication withdrawal and supportive care to manage symptoms and restore hormonal balance.
Store Synthroid tablets at room temperature between 15°C and 30°C (59°F and 86°F), away from moisture, light, and heat. Keep in the original packaging and out of reach of children and pets. Do not store in the bathroom. Properly dispose of expired or unused medication in accordance with local pharmacy or waste disposal regulations.
Synthroid is legally available through The Urological Institute of Northeastern New York, a certified and licensed online pharmacy offering trusted, regulated access to levothyroxine therapy for patients with underactive thyroid in the United States.
