Levothyroxine (brand name Synthroid®) is the most commonly prescribed thyroid hormone replacement worldwide. Its well-established efficacy and safety profile make it a first-line therapy for hypothyroidism.

Physicians exercise caution because Levothyroxine dosing must be individualized: over-replacement can cause heart palpitations, bone loss, or anxiety, while under-replacement leaves the patients symptomatic. They often require recent lab tests (TSH, T3, free T4) and clinical evaluation before issuing or adjusting a prescription.

Levothyroxine is generally well tolerated when dosed correctly. Because it is identical to endogenous T4, side effects are uncommon if TSH is kept within the target range. Alternatives (e.g., desiccated thyroid extract) carry a higher risk of dose variability and adverse reactions.

With our telehealth service, simply register, complete a brief intake (including your last TSH value), and meet virtually with a provider. If you qualify, they will e-prescribe your Synthroid® and a refill will be faxed directly to your chosen pharmacy.

Unopened Levothyroxine retains full potency until the expiration date printed on the package (typically 18–24 months from manufacture). After opening, most manufacturers recommend using it within one year, stored in its original container away from moisture and heat.

Yes, once you have a valid prescription. After your telehealth consult, your e-script can be sent to any participating online or brick-and-mortar pharmacy for same-day or mail delivery.

No. Levothyroxine is a prescription-only medication because dose monitoring via TSH and periodic lab tests is necessary. Any site claiming to sell it OTC operates outside legal regulations and may supply unsafe products.

We offer transparent plans, such as a family sharing plan. Before your virtual visit, you’ll see all costs upfront before agreeing to refill your prescription.

Levothyroxine replaces deficient thyroid hormone in conditions such as primary hypothyroidism (e.g., Hashimoto’s), post-thyroidectomy, or after radioactive iodine therapy. It normalizes metabolic functions, energy levels, and temperature regulation.

Take your tablet once daily on an empty stomach, ideally 30–60 minutes before breakfast, with a full glass of water. Avoid calcium, iron, or antacids within four hours of your dose, as they impair absorption.

If you forget, take it as soon as you remember, unless it’s within 4 hours of your next scheduled dose. Do not double up. Consistency is key to maintaining steady thyroid levels.

You may feel symptomatic improvement (less fatigue, clearer thinking) within 2 weeks, but complete biochemical stabilization (normal TSH) can take 6–8 weeks. Your provider will schedule follow-up labs accordingly.

No. Even small changes in Levothyroxine (e.g., from 100 mcg to 112 mcg) significantly affect thyroid levels. Always consult your provider via telehealth before making any dose adjustments.

It takes time for the body to adjust to the medicine. Generally, individuals notice an improvement 6 weeks after taking Levothyroxine. For others, it can take longer to see significant effects.

Levothyroxine has several drug interactions. Some classes of drugs that it interacts with include Antacids, Bile acid sequestrants, PPIs, Beta-blockers, etc. It also interacts with beverages and food items, including coffee, grapefruit juice, alcohol, walnuts, etc.

Levothyroxine (Levoxyl, Synthroid, etc.) must be taken lifelong by individuals who have undergone a thyroidectomy or radioiodine therapy. It provides thyroid hormones to the body. Medication is also required to maintain a healthy blood calcium level if the parathyroid glands have been removed during surgery.
