Levothyroxine

Synthroid

Synthroid (levothyroxine) is an FDA-approved medication used in the treatment of hypothyroidism, a condition where the thyroid gland doesn’t produce enough thyroid hormone. It contains a synthetic form of thyroxine (T4) to regulate the body’s energy and metabolism. Available in various strengths from 25 mcg to 300 mcg, this medication is taken once daily on an empty stomach. Dosages are tailored to individual needs, with regular monitoring by a healthcare provider. Patients must practice awareness of potential side effects and follow prescribed dosages carefully. Store Synthroid at room temperature, away from light and moisture.

Product Overview

Synthroid (levothyroxine) regulates the body’s energy and metabolism. It is mainly used to treat hypothyroidism, a condition where the thyroid gland lacks the production of enough thyroid hormone, resulting in fatigue, weight gain, and cold sensitivity. Synthroid works by supplementing the body’s natural thyroid hormone levels, helping to restore normal bodily functions and alleviate the symptoms of hypothyroidism. It also treats thyroid cancer and suppresses thyroid-stimulating hormone (TSH) levels.

Synthroid has various strengths, ranging from 25 micrograms (mcg) to 300 mcg, allowing for precise dosage adjustments based on individual needs. It should be taken once daily, preferably on an empty stomach, 30 to 60 minutes before breakfast, to ensure optimal absorption. The dosage is tailored to each patient, considering age, body weight, medical condition, and response to treatment. Regular monitoring by a medical professional is essential to adjust the dosage as needed and ensure the effectiveness of the treatment.

It is important to be aware of the side effects of taking this medication. Some of these are increased appetite, weight loss, nervousness, and insomnia. It is important to follow the prescribed dosage and not use Synthroid for weight loss or obesity treatment. Special precautions should be taken for patients with heart disease, adrenal insufficiency, or bone health issues. In case of a missed dose, take it as soon as possible, but skip it if it’s close to the next scheduled dose. For overdose, seek immediate medical attention. Store Synthroid at room temperature, away from light and moisture, and keep it out of reach of children and pets.

What Are the Recommended Synthroid Doses for Different Patients?

The dosage of Synthroid (levothyroxine) required can vary significantly between individuals, based on several factors including age, weight, the severity of hypothyroidism, the presence of other health conditions, and the use of certain medications. Here are general guidelines for Synthroid dosing across different patient categories:

For Adults with Primary Hypothyroidism

  • The typical starting dose is 1.6 micrograms per kg of body weight per day. For example, a 70 kg adult might start with a dose of 112 micrograms daily.

For Elderly Patients

  • Older adults may start with a lower dose, such as 25 to 50 micrograms per day, to reduce the risk of cardiac side effects. The dosage can be gradually increased based on the response and tolerance.

For Children

  • The dosage for children depends on their age, weight, and the severity of their condition. Newborns with congenital hypothyroidism might require 10 to 15 micrograms/kg/day, while older children might require less.

For Pregnant Women

  • Women with hypothyroidism who become pregnant may need to increase their dosage of Synthroid, as pregnancy increases the body’s demand for thyroid hormones.

For Patients with Thyroid Cancer

  • Higher doses of Synthroid may be used to suppress thyroid-stimulating hormone (TSH) levels in patients with thyroid cancer.

[Note: Remember these recommendations may vary depending on person to person. Discuss it with your doctor, and they’ll customize your dosage accordingly.]

How to Use Synthroid?

Synthroid (levothyroxine sodium) is a medication used to treat hypothyroidism (underactive thyroid). Here’s how to use it effectively:

  • Take Synthroid at the same time each day to maintain stable hormone levels.
  • Take it on an empty stomach, ideally 30 to 60 minutes before breakfast. Food can interfere with its absorption.
  • Swallow the tablet with a full glass of water. This helps ensure the tablet dissolves properly in the stomach.
  • Do not take calcium or iron supplements, antacids, or multivitamins within 4 hours of taking Synthroid, as they can reduce its effectiveness.
  • Take Synthroid precisely as prescribed by your doctor. Do not adjust your dose or buy Synthroid online extra without consulting them.
  • Have regular check-ups with your medical professional to keep your thyroid levels in check and adjust your dosage if necessary.

[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]

How Does Synthroid Work?

Synthroid (levothyroxine) works by supplementing or replacing the natural thyroid hormone, helping regulate the body’s energy and metabolism. When taken as prescribed, Synthroid restores normal thyroid hormone levels, alleviating symptoms of hypothyroidism such as fatigue, weight gain, and cold sensitivity and helping to maintain normal bodily functions.

Important Safety Information

What Are the Side Effects of Synthroid?

Common side effects may include:

  • Increased Appetite: Synthroid, a medication primarily used to treat hypothyroidism, may lead to an increased appetite in some patients. This effect arises as the body adjusts to heightened levels of thyroid hormone, which can enhance metabolic rates and trigger a greater desire for food. Individuals may notice a marked increase in their hunger levels, prompting a need for careful dietary management to avoid excessive weight gain.
  • Weight Loss: While it might seem contradictory to the increase in appetite, Synthroid can also cause weight loss. This occurs because the medication elevates metabolism, leading the body to burn calories at a faster rate. Even with an increased appetite, the overall caloric expenditure can still result in a net loss of weight, which should be monitored to ensure it remains within healthy limits.
  • Nervousness or Anxiety: Some users of Synthroid experience nervousness or anxiety as a side effect. These feelings are typically the result of the body’s heightened metabolic and nervous system activity due to increased thyroid hormones. Patients might feel unusually jittery or anxious, particularly when they first begin treatment or undergo dosage adjustments.
  • Insomnia: The stimulating effects of Synthroid on the central nervous system can lead to difficulties in falling or staying asleep. Insomnia may occur because the increased levels of thyroid hormones can cause heightened alertness that disrupts normal sleep patterns. It is crucial for patients to establish a calming bedtime routine and consult healthcare providers if sleep disturbances persist.
  • Tremors or Shaking: Tremors or shaking are possible physical manifestations of Synthroid’s impact on the nervous system. These involuntary muscle movements usually occur in the hands and can be a distressing side effect for those affected. Adjusting the medication dose under medical supervision can help alleviate this symptom.
  • Sweating: Excessive sweating is another side effect linked to the thermogenic (heat-producing) properties of Synthroid. As the body’s metabolism increases, so does its heat production and the subsequent need to dissipate this excess heat through sweating. Patients may find themselves sweating more than usual, even in cooler conditions.
  • Increased Heart Rate or Palpitations: Synthroid can cause an increase in heartbeat or palpitations, which are sensations of a racing or irregular heartbeat. These cardiovascular responses are due to the stimulating effect of thyroid hormones on the heart, requiring monitoring, especially in patients with pre-existing heart conditions.
  • Diarrhea or Stomach Cramps: Gastrointestinal disturbances such as diarrhea or stomach cramps can also occur as the body adapts to increased levels of thyroid hormones. These symptoms can be uncomfortable & may require dietary adjustments or additional medical treatments to manage.
  • Headaches: Headaches are a less specific but reported side effect of Synthroid. They can vary in intensity and frequency, potentially linked to the body’s overall increased metabolic rate or changes in blood pressure resulting from the medication.
  • Sensitivity to Heat: As Synthroid increases metabolic rate, it can lead to an enhanced sensitivity to heat. Patients might feel uncomfortably warm and prone to overheating, a direct result of the body’s heightened energy consumption and heat production.

Serious side effects may include:

  • Weight Fluctuations: Synthroid may lead to changes in weight due to its influence on metabolism. Patients might experience unexpected weight gain or loss as their bodies adjust to the medication. This is because Synthroid can accelerate or decelerate metabolic rates, which affects how the body processes fats, proteins, and carbohydrates.
  • Muscle Aches and Leg Cramps: A common side effect of Synthroid is muscle aches and leg cramps. This discomfort arises because the medication can alter electrolyte balances in the body, especially if the dosage is not adequately adjusted, leading to muscle pain and spasms.
  • Hair Loss and Dryness of Skin or Hair: Users of Synthroid might notice their hair thinning or becoming dry, along with a similar effect on their skin. This occurs because thyroid hormones, which Synthroid influences, play a crucial role in the health and regeneration of hair follicles and skin cells.
  • Alterations in Menstrual Periods: Women taking Synthroid may experience changes in their menstrual cycles, such as irregular periods or increased menstrual flow. These alterations result from the medication’s impact on the hormonal balance, which is tightly linked to the menstrual cycle.
  • Nervousness, Feeling Depressed, or Irritability: Emotional side effects such as nervousness, irritability, or depression are associated with Synthroid, likely due to its effect on the central nervous system and the regulation of neurotransmitters that influence mood and emotions.
  • Memory Problems & Trouble Sleeping (Insomnia): Some patients on Synthroid report memory issues and insomnia. These cognitive and sleep disturbances can be attributed to the way Synthroid influences brain function and alertness levels.
  • Weakness and Tiredness: Even though Synthroid is used to treat hypothyroidism, which often causes fatigue, some users might feel unusually weak or tired as their body adjusts to the medication or if the dose is imbalanced.
  • Experiencing Hot Flashes or Feeling Cold: Individuals taking Synthroid may occasionally feel unusually cold or suffer from hot flashes. These symptoms reflect the body’s attempt to regulate temperature in response to fluctuating thyroid hormone levels.
  • Fever and Sweating: Fever and increased sweating can occur as side effects of Synthroid, especially when beginning treatment or changing doses. These symptoms indicate the body’s sensitivity to changes in thyroid hormone levels.
  • Tremors and Shaking: Tremors or shaking are potential side effects of Synthroid, generally due to overstimulation of the nervous system when the dosage might be too high or not yet properly adjusted.
  • Chest Pain and Shortness of Breath: Severe but rare chest pain and shortness of breath may indicate an adverse reaction to Synthroid, necessitating immediate medical attention. These symptoms can signal that the heart is being affected by the altered levels of thyroid hormone.
  • Rapid or Irregular Heartbeats: Synthroids can lead to cardiovascular side effects such as rapid or irregular heartbeats, which are known as palpitations. These occur because thyroid hormones have a direct effect on heart rate and rhythm, and any imbalance might manifest through these symptoms.

[Note: Remember, this list may not cover all possible side effects. Always consult with your healthcare giver for medical advice about side effects.]

Warnings: What Are the Synthroid Warnings?

When you buy Synthroid 137 mcg tablets from Canada, you can consider the side several warnings associated with this medication:

  • Thyroid Hormone Replacement: Synthroid is intended for use as a thyroid hormone replacement therapy. It should not be used for weight loss or to treat obesity.
  • Correct Diagnosis: Ensure that your diagnosis of hypothyroidism is confirmed by appropriate testing before starting treatment with Synthroid.
  • Heart Disease: Patients with existing heart disease or cardiovascular disorders should be closely monitored, as levothyroxine can increase the risk of heart-related complications.
  • Adrenal Insufficiency: Patients with untreated adrenal insufficiency should not take Synthroid until the adrenal problem is addressed, as it can lead to a severe condition called adrenal crisis.
  • Bone Health: Long-term use of high doses of Synthroid can lead to decreased bone density and a heightened risk of osteoporosis and fractures, especially in postmenopausal women and elderly patients.

  • Allergies: If you have had allergic reactions to levothyroxine or any other medications in the past, inform your healthcare provider.
  • Medical Conditions: Maintain transparency regarding any medical conditions you may have, particularly if there have been signs of heart disease, diabetes, adrenal gland problems, or osteoporosis.
  • Pregnancy and Breastfeeding: Get in touch with your healthcare provider if you are expecting pregnancy or breastfeeding, as your Synthroid dosage may need to be adjusted.
  • Surgery: If you are to undergo any surgery, inform your surgeon that you are taking Synthroid.
  • Avoid Switching Brands: Try to stick with the same brand or generic version of levothyroxine, as different brands may have slightly different effects.
  • Dietary Considerations: Be mindful of foods that may affect thyroid hormone absorption, such as soy products and high-fiber foods. Also, avoid taking calcium and iron supplements within 4 hours of taking Synthroid.

What Are Synthroid Contraindications?

  • Patients with untreated adrenal insufficiency should not use Synthroid.

Missed Dose: What Happens If You Miss a Dose of Synthroid?

Here are the guidelines you need to follow in case of missing dose of Synthroid: 

  • If you forget to take a dose, take it when you remember.
  • If it’s almost time for another dosage of Synthroid, leave the missed dosage and continue with your routine medication consumption.
  • Do not take a double dose to make up for the missed one unless your doctor instructs you to do so. 
  • If you miss two or more doses consecutively, contact your doctor. 

[Note: If you have missed a dose of your medication and are unsure about when to take the next one, immediately consult your doctor or pharmacist.]

Overdose: What Happens If You Take Too Much Synthroid?

If you accidentally consume more than the recommended doses of Synthroid, follow these guidelines: 

  • In severe cases, an overdose of Synthroid can lead to more serious conditions such as thyrotoxic crisis or thyroid storm, which can be life-threatening.
  • If you suspect an overdose of Synthroid 137 mcg, seek immediate medical attention.
  • Treatment for an overdose may involve reducing the dosage of Synthroid, administering medications to counteract the symptoms, and monitoring vital signs and thyroid hormone levels.

[Note: If you consumed more than recommended dose, get medical help right away, or call the Poison Help line at 1-800-222-1222.]

Storage: How Do You Store Synthroid?

If you want to buy Synthroid online, you should know how to store this medication for better use. Here are the storage considerations you need to follow:

  • Store at room temperature, ideally between 68°F to 77°F (20°C to 25°C). Avoid exposure to extreme temperatures, as it can affect the medication’s potency.
  • Keep the medication in its original container and tightly closed to protect it from light and moisture. Do not store in the bathroom or other damp areas.

What Are the Synthroid Interactions?

Understanding the interactions of Synthroid is important for managing your treatment effectively. Here are some common interactions to be aware of:

  • Calcium carbonate and iron supplements: These can reduce the absorption of levothyroxine if taken too close together. It’s recommended to take these supplements at least 4 hours before or after taking levothyroxine.
  • Cholestyramine and colestipol: These bile acid sequestrants can decrease levothyroxine absorption. Take levothyroxine at least 4 hours before or 1 hour after these medications.
  • Antacids and proton pump inhibitors (PPIs): Medications like omeprazole, lansoprazole, and antacids containing aluminum or magnesium can decrease the absorption of levothyroxine.
  • Sucralfate: This medication can also reduce the absorption of levothyroxine. Take levothyroxine at least 2 hours before sucralfate.
  • Warfarin: Levothyroxine can increase the effect of warfarin, potentially increasing the chances of bleeding. Regular monitoring of INR (International Normalized Ratio) is recommended.
  • Beta-blockers (e.g., propranolol, metoprolol): These medications can reduce the effectiveness of levothyroxine in some patients.
  • Amiodarone: This medication can affect thyroid function and may require adjustments in levothyroxine dosage.
  • Antidepressants (e.g., sertraline, fluoxetine): These can affect levothyroxine metabolism and may require dosage adjustments.
  • Insulin and oral hypoglycemics: Levothyroxine may increase the effect of these medications, potentially leading to hypoglycemia.
  • Estrogens (e.g., oral contraceptives, hormone replacement therapy): These can increase the amount of levothyroxine needed by the body.

What Are the Other Synthroid Interactions?

Synthroid (levothyroxine) can interact with a range of substances, including alcohol, various supplements, herbs, and certain foods. 

    • Alcohol: Moderate to heavy alcohol consumption can affect liver function, which in turn can influence how your body metabolizes levothyroxine. Additionally, alcohol may alter thyroid hormone levels and thyroid gland function, potentially requiring adjustments in Synthroid dosage.
  • Supplements & Herbs:
  • Iodine: Excessive iodine intake can either trigger or exacerbate hyperthyroidism or hypothyroidism, particularly in individuals with existing thyroid issues.
  • Selenium & Zinc: These minerals are essential for thyroid function and hormone synthesis. However, excessive amounts might interfere with Synthroid effectiveness.
  • Biotin: High doses of biotin can interfere with thyroid function tests, leading to incorrect readings. It’s usually recommended to stop biotin supplements several days before thyroid testing.
  • Foods:
    • Cruciferous Vegetables: Broccoli, cauliflower, kale, and cabbage can interfere with thyroid hormone synthesis if consumed in very large quantities, which is particularly relevant in people with iodine deficiencies.
    • Walnuts, Cottonseed Meal, and Soy: These contain substances that may interfere with the absorption of levothyroxine. They should not be consumed at the same time as Synthroid.
    • High-Fiber Foods: While beneficial for overall health, high fiber intake can reduce levothyroxine absorption. It’s advised to monitor thyroid function if you significantly change your fiber intake.
    • Coffee: These beverages, especially when consumed shortly after taking Synthroid, can reduce the absorption of the medication. It’s best to take Synthroid on an empty stomach with water and wait at least 30 to 60 minutes before consuming coffee.

[Note: This isn’t a complete list, and there could be other drugs that interact with Synthroid. Make sure to tell your doctor any prescription, over-the-counter medicines, and herbal products you’re taking.]

Frequently Asked Questions

Does a lower dosage of Synthroid decrease the likelihood of experiencing side effects?

It’s possible, but it’s essential to first identify the appropriate dosage of Synthroid for your condition. If you’re encountering side effects from Synthroid, your doctor might reduce your dosage, which could alleviate your symptoms. However, if the dosage of Synthroid is too low, you might experience symptoms of the condition it’s intended to treat. Consult with your doctor to learn more about reducing your risk of side effects from Synthroid. Additionally, if you experience side effects during treatment or have questions about adjusting your dosage, be sure to discuss them with your doctor.

Will my Synthroid dosage need adjustment if I experience weight loss?

Yes, it’s possible. The recommended dosages of Synthroid are often determined based on weight. If you experience a significant change in weight while taking Synthroid, your doctor may need to adjust your dosage. However, minor weight fluctuations don’t typically necessitate a change in dosage.

What should I do if I miss a dose of Synthroid?

If you forget to take a dose of Synthroid, take it as soon as you remember. However, if it’s almost time for your next dose, skip the dosage you missed and continue with your regular medication intake schedule. Do not take a double dose to make up for the missed dosage, as this can increase your risk of experiencing side effects. If you’re unsure about whether to take a missed dose or skip it, consult with your doctor or pharmacist for guidance.

Is it possible to take levothyroxine at night?

You can take levothyroxine at night, but ensure it is taken at least 4 hours after your last meal. Studies indicate that levothyroxine can be equally effective when taken at night, provided it is taken separately from food and other medications.
