Synthroid Levothyroxine Sodium: Side Effects, Uses, Dosage, Interactions, Warnings

Monitor for cardiac arrhythmias during surgical procedures in patients with coronary artery disease receiving suppressive SYNTHROID therapy. Monitor patients receiving concomitant SYNTHROID and sympathomimetic agents for signs and symptoms of coronary insufficiency. Consider changes in TBG concentration when interpreting T4 and T3 values.

Cardiac Adverse Reactions In The Elderly And In Patients With Underlying Cardiovascular Disease

• Thyroid hormones can also be present illicitly in some over-the-counter weight loss products.
• Levothyroxine is generally continued for life in these patients see WARNINGS AND PRECAUTIONS.
• In adults, thyroid hormone helps to maintain brain function, utilization of food, and body temperature, among other effects.
• Some people might use their levothyroxine prescriptions for this reason, but it’s important to know that the use of levothyroxine for weight loss can result in dangerous and potentially life-threatening side effects.
• This hormone nuclear receptor complex activates gene transcription and synthesis of messenger RNA and cytoplasmic proteins.

Concurrent use of sympathomimetics and SYNTHROID may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease. If symptoms occur, they often are due to toxic levels of thyroid hormone, and the symptoms are those of hyperthyroidism. Synthroid is dosed based on weight, and while that works for most women, sometimes it can overcorrect your thyroid and make it overactive, Goldfarb says. One sign that you’ve entered into hyperthyroid territory is a racing or irregular heart rate.

Antidiabetic Therapy

It may take several weeks before your body starts to respond to Synthroid. Follow all directions on your prescription label and read all medication guides or instruction sheets. SYNTHROID is not indicated for treatment of hypothyroidism during the recovery phase of subacute thyroiditis. Although millions of people have hypothyroidism, there are many misconceptions around managing it.

Seizures have been reported rarely with the institution of levothyroxine therapy. Patients The SYNTHROID dosage is based on the target level of TSH suppression for synthroid tramadol the stage and clinical status of thyroid cancer. Inquire whether patients are taking biotin or biotin-containing supplements. If so, advise them to stop biotin supplementation at least 2 days before assessing TSH and/or T4 levels see DOSAGE AND ADMINISTRATION and DRUG INTERACTIONS. Levoxyl treats hypothyroidism (low thyroid hormone) and treats or prevents goiter.

Thyroid hormones are also metabolized via conjugation with glucuronides and sulfates and excreted directly into the bile and gut where they undergo enterohepatic recirculation. Oral levothyroxine sodium is a synthetic T4 hormone that exerts the same physiologic effect as endogenous T4, thereby maintaining normal T4 levels when a deficiency is present. Thyroid hormones exert their physiologic actions through control of DNA transcription and protein synthesis. Triiodothyronine (T3) and L-thyroxine (T4) diffuse into the cell nucleus and bind to thyroid receptor proteins attached to DNA. This hormone nuclear receptor complex activates gene transcription and synthesis of messenger RNA and cytoplasmic proteins. The physiological actions of thyroid hormones are produced predominantly by T3, the majority of which (approximately 80%) is derived from T4 by deiodination in peripheral tissues.

These interactions can be avoided if levothyroxine is taken at least 30–60 minutes before consuming any of these foods and beverages. It’s generally safe to drinkalcohol as long as the alcohol is not consumed at the same time as the levothyroxine dose. Thyroid hormone increases metabolic clearance of glucocorticoids. Initiation of thyroid hormone therapy prior to initiating glucocorticoid therapy may precipitate an acute adrenal crisis in patients with adrenal insufficiency. Treat patients with adrenal insufficiency with replacement glucocorticoids prior to initiating treatment with SYNTHROID see CONTRAINDICATIONS.

Some people might use their levothyroxine prescriptions for this reason, but it’s important to know that the use of levothyroxine for weight loss can result in dangerous and potentially life-threatening side effects. Thyroid hormones can also be present illicitly in some over-the-counter weight loss products. These dietary supplements can contain varying amounts of thyroid hormones, which can be dangerous and cause adverse effects. Because of this, people should not take over-the-counter weight loss supplements.

Dosing And Administration

Therefore, a decrease in the dose of anticoagulant may be warranted with correction of the hypothyroid state or when the SYNTHROID dose is increased. Closely monitor coagulation tests to permit appropriate and timely dosage adjustments. Pseudotumor cerebri and slipped capital femoral epiphysis have been reported in pediatric patients receiving levothyroxine therapy. For adult patients with primary hypothyroidism, titrate until the patient is clinically euthyroid and the serum TSH returns to normal see Recommended Dosage And Titration. SYNTHROID is indicated in adult and pediatric patients, including neonates, as a replacement therapy in primary (thyroidal), secondary (pituitary), and tertiary (hypothalamic) congenital or acquired hypothyroidism. Consumption of certain foods and beverages such as soybean flour, cotton seed meal, walnuts, grapefruit juice, coffee, and dietary fiber can decrease the absorption of levothyroxine.
