Eltroxin® Tablets for Hypothyroidism

Eltroxin is levothyroxine, a thyroid hormone replacement used to treat low thyroid. It helps restore normal hormone levels and ease related symptoms. We offer US shipping from Canada so you can access this therapy even if paying without insurance.

What Eltroxin Is and How It Works

Eltroxin® contains levothyroxine sodium, a synthetic form of thyroxine (T4). Your body converts T4 to the active hormone T3, which supports metabolism, heart function, and growth. Restoring T4 helps normalize thyroid-stimulating hormone (TSH) and relieve signs of hypothyroidism like fatigue and cold intolerance. For some patients after thyroid cancer treatment, levothyroxine may also be used to suppress TSH under a prescriber’s supervision.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine works best when taken consistently on an empty stomach. Keep the brand and timing stable to help your clinician interpret TSH and free T4 results. Do not use thyroid hormone for weight loss or to treat obesity.

Who It’s For

This treatment is indicated for primary, secondary, or tertiary hypothyroidism in adults and children, including congenital or postoperative hypothyroidism. It may be used to suppress TSH in certain thyroid cancer settings when a specialist recommends it. People with untreated adrenal insufficiency should not start levothyroxine until the adrenal condition is managed. Use caution in those with heart disease, arrhythmias, or recent myocardial infarction. Tell your prescriber about pregnancy or breastfeeding, as dose needs may change under medical guidance.

Dosage and Usage

Take levothyroxine once daily on an empty stomach with a full glass of water. Many people take levothyroxine sodium 100 mcg tablets in the morning, 30 to 60 minutes before breakfast. If mornings are difficult, you may take it at bedtime at least 3 to 4 hours after the last meal, provided you keep the schedule consistent. Swallow tablets whole. For infants who cannot swallow tablets, the prescriber may advise crushing and mixing with a small amount of water; do not mix with soy-based formulas.

Separate this medicine from iron, calcium, magnesium, aluminum antacids, bile acid sequestrants, and sucralfate by several hours, as these can reduce absorption. Try to avoid taking it with high-fiber meals, soy, or coffee at the same time. Your clinician will guide dose changes using lab tests and clinical response. Always follow the official label and your prescriber’s directions.

Strengths and Forms

This therapy is supplied as oral tablets in multiple color-coded strengths. Commonly available strengths include 25 mcg, 50 mcg, 75 mcg, 88 mcg, Eltroxin 100 mcg tablets, 112 mcg, 125 mcg, 137 mcg, 150 mcg, and 200 mcg. Availability can vary by supplier and stock. Your prescriber will choose the strength that fits your needs.

Missed Dose and Timing

If you miss a dose, take it when you remember the same day. If it is close to the next scheduled dose, skip the missed dose and resume your regular time. Do not double up. If you regularly forget doses, speak with your healthcare professional about reminders or timing adjustments. Some patients using Eltroxin 0.1 mg tablets find that pairing the dose with a daily routine helps with adherence.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from moisture and direct light. Keep the medicine in the original container, tightly closed, and out of reach of children and pets. Avoid bathroom storage due to humidity. When traveling, bring enough supply, a copy of your prescription, and your prescriber’s contact details. Use a pill organizer only if it protects from light and moisture. Do not use tablets that are discolored, chipped, or damaged.

Benefits

When taken as directed, thyroid hormone replacement can reduce fatigue, support a stable heart rate, and improve cold intolerance linked to low thyroid levels. Once-daily dosing supports routine use. Stable dosing and timing help maintain consistent TSH targets chosen by your prescriber.

Side Effects and Safety

• Headache or nervousness
• Palpitations or faster heart rate
• Heat intolerance or sweating
• Sleep difficulty
• Diarrhea or stomach upset
• Hair shedding at start of therapy

Excess dosing can cause symptoms of hyperthyroidism, including chest pain, shortness of breath, or tremor. Rare but serious effects include arrhythmias, angina, or bone loss with long-term overtreatment. Seek urgent care for severe chest pain, fainting, or severe allergic reactions. People with diabetes may need closer monitoring of glucose. Those on blood thinners may require monitoring as thyroid hormone can affect anticoagulant response.

Drug Interactions and Cautions

Tell your clinician about all medicines and supplements. Iron, calcium, aluminum/magnesium antacids, sucralfate, bile acid sequestrants, and orlistat can reduce absorption. Separate them by several hours. Enzyme inducers such as carbamazepine, phenytoin, or rifampin may increase hormone clearance. Amiodarone and lithium can affect thyroid function. Warfarin sensitivity may increase as thyroid function normalizes. Diabetes medicines may need monitoring. Do not change brands or strengths without consulting your prescriber.

What to Expect Over Time

Thyroid replacement works gradually. Your clinician will use lab tests to assess response and adjust your regimen if needed. Consistent timing, avoidance of interfering supplements around the dose, and continuous daily use support more stable results. Do not stop therapy abruptly unless your prescriber tells you to. If a pharmacy substitution is offered, ask whether it matches your current brand and strength.

Compare With Alternatives

Brand and generic levothyroxine products are available. Synthroid® is another branded levothyroxine with a long market history. Generic options may also be suitable if your prescriber approves staying with one manufacturer consistently. Some patients who need T3 support may be prescribed liothyronine separately by a specialist. Ask your clinician which approach best fits your history and lab goals. Many people use generic levothyroxine 100 mcg tablets when a consistent supply is confirmed.

Availability and Substitutions

Stock can vary by strength. If a specific presentation is temporarily unavailable, your prescriber may recommend a therapeutically equivalent alternative or a different strength combination. Pharmacy teams only substitute within regulatory guidelines and with prescriber approval when required. Keep your brand and manufacturer consistent unless your clinician advises a change.

Patient Suitability and Cost-Saving Tips

People with a diagnosis of hypothyroidism or requiring TSH suppression may be candidates for levothyroxine. Those with untreated adrenal insufficiency should avoid starting until managed. Tell your clinician about heart disease, osteoporosis, or pregnancy before use. For savings, consider multi-month fills if appropriate, and set refill reminders so you do not miss doses. Consistent brand and timing help avoid repeat lab visits due to variability.
