How Levothyroxine (Euthyrox) works

Levothyroxine (Euthyrox) is a lab-made version of the thyroid hormone called thyroxine or T4 that's made by your thyroid gland. Thyroid hormones have important functions like controlling your metabolism, body temperature, heart rate, and more. When the amount of hormone is too low in your body, taking this thyroid hormone medication can bring your levels back to normal.

Pharmacist tips for Levothyroxine (Euthyrox)

pharmacist

  • Take levothyroxine (Euthyrox) 30 minutes to 1 hour before breakfast on an empty stomach. This helps the full amount of medication get absorbed into your body.

    • It's important to keep up with all of your follow-up appointments for laboratory testing while you're taking levothyroxine (Euthyrox). Your provider will adjust your dose based on your thyroid hormone levels from your blood test results.

      • Most of the side effects of levothyroxine (Euthyrox) are symptoms of hyperthyroidism (high thyroid hormone levels). Talk with your provider if you have symptoms like anxiety, fast heart rate, or unusual sweatiness because it might mean your dose is too high.

        • You might have some hair loss during the first few months of starting levothyroxine (Euthyrox). This is usually rare and temporary; it should stop as you continue taking the medication.

          • There are many brands and formulations of levothyroxine available. It's best to try to stick with the same generic or same brand of levothyroxine. Also, don't switch manufacturers of the levothyroxine you're taking without speaking to your provider first. Your body might not respond to all forms of levothyroxine in the same way.

            • If you switch to a different form of levothyroxine, your provider might order blood work to check your thyroid levels and make sure your medication is working well for you.

              Frequently asked questions about Levothyroxine (Euthyrox)

              How long does it take for levothyroxine (Euthyrox) to work?
              It can take 4 to 6 weeks after you start levothyroxine (Euthyrox) to see or feel the full benefits from the medication. But some people might notice that their symptoms start to improve earlier than that. Keep in mind that when you first start the medication, it might take a few months for your provider to find a dose that works best for you. To do so, your provider will periodically check your thyroid hormone levels to see whether it's within the target range. Your provider might also raise your dose slowly over time to avoid side effects of having too much thyroid hormone, like headache and nausea. Ask your provider if you're not sure whether levothyroxine (Euthyrox) is working for you.
              Can you take levothyroxine (Euthyrox) with other medications?
              You might need to take levothyroxine (Euthyrox) and your other medications at different times to avoid drug interactions. How long you should wait between taking levothyroxine (Euthyrox) and your other medications can depend on the specific medication. For example, take certain antacids like Tums at least 4 hours apart from levothyroxine (Euthyrox). Some medications can lessen how much levothyroxine gets absorbed into the body and make your thyroid medication work less well. Other medications might lead to too much levothyroxine in your body and cause symptoms of hyperthyroidism. Ask your pharmacist whether you need to separate your medications and when the best time is to take them.
              What if you eat too soon after levothyroxine (Euthyrox)?
              Eating too soon after you take levothyroxine (Euthyrox) can affect how well your body can absorb the medication. For example, foods that are high in fiber, soy products, and walnuts can lessen how much levothyroxine (Euthyrox) gets absorbed into the body. For this reason, the manufacturer of levothyroxine (Euthyrox) recommends taking your dose at least 30 minutes to 1 hour before food and on an empty stomach.
              Can you take levothyroxine (Euthyrox) at night?
              The manufacturer of levothyroxine (Euthyrox) states that it's best to take levothyroxine (Euthyrox) in the morning at least 30 minutes before breakfast. This is because the medication gets absorbed into the body better on an empty stomach. Some research shows that levothyroxine (Euthyrox) can work just as well at night as it does in the morning, as long as you separate it from food and other medications. If you decide to take levothyroxine (Euthyrox) at night, make sure that you take it at least 4 hours after the last meal you've had.
              How long after taking levothyroxine (Euthyrox) can you drink coffee?
              Try to wait 1 hour after you take your levothyroxine (Euthyrox) dose before drinking any coffee. Drinking coffee with levothyroxine (Euthyrox) can lower the amount of medication that your body absorbs. This can potentially make the medication work less well for you.
              Can levothyroxine (Euthyrox) cause weight gain?
              Levothyroxine (Euthyrox) isn't known to cause weight gain. But it's possible for you to experience weight gain while you're taking this medication. Rather than a side effect of levothyroxine (Euthyrox), weight gain is typically a sign of undertreatment. This means that your dose isn't enough to bring your thyroid hormone levels up to the target range. Tell your provider if you have concerning weight gain while you're taking levothyroxine (Euthyrox). Your provider might need to check your thyroid hormone levels to make sure your dose is appropriate and adjust it if needed.

              What are the risks and warnings for Levothyroxine (Euthyrox)?

              Levothyroxine (Euthyrox) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

              risk-warning

              Not for weight loss

              • Risk factors: Taking other medications for weight loss

                Levothyroxine (Euthyrox) shouldn't be used for weight loss. It’s not recommended, safe, or effective for this use. Taking high doses of levothyroxine (Euthyrox) can cause serious or fatal effects especially if it's used with other medications for weight loss.

                risk-warning

                Heart problems

                • Risk factors: Current heart disease | Age 65 or older

                  Taking too much levothyroxine (Euthyrox) can cause heart problems, especially for older adults or people with heart conditions. Call your provider or get medical care right away if you have rapid or irregular heartbeat, chest pain, or trouble breathing. Your provider might need to lower your dose or have you stop taking the medication if you develop new heart problems.

                  risk-warning

                  Dangerously low stress hormone levels (adrenal crisis)

                  • Risk factors: Adrenal insufficiency | Addison's disease

                    In rare cases, some people can have low thyroid hormone levels and low adrenal hormone levels at the same time. Let your provider know if you have Addison's disease, a medical condition that happens when you have low adrenal hormone levels. It's important that you're treated for this adrenal problem first before your thyroid condition. Otherwise, taking levothyroxine (Euthyrox) can cause your adrenal hormone levels to drop even lower and make you feel unwell.

                    Your provider should check your adrenal hormone levels before prescribing levothyroxine (Euthyrox). Seek medical attention right away if you experience long-lasting tiredness, stomach pain, dizziness, weakness, or vomiting while you're taking levothyroxine (Euthyrox).

                    risk-warning

                    Worsening diabetes

                    • Risk factors: Diabetes

                      Levothyroxine (Euthyrox) can raise your blood sugar levels, especially when you first start this medication and when your provider raises your dose. If you already have diabetes, your provider might need to adjust the dose of your blood sugar medications. Continue to check your blood sugar levels as directed by your provider. Talk to your provider if your blood sugar readings are higher than usual.

                      risk-warning

                      Weak bones with high doses

                      • Risk factors: Postmenopausal women | Higher doses

                        Taking too high of a dose of levothyroxine (Euthyrox) can weaken your bones. Women who've gone through menopause are particularly at risk for bone loss. To lower your risk, your provider will check your thyroid hormone levels to make sure you're taking the lowest dose needed to treat your thyroid condition. Make sure to get plenty of exercise, eat a bone-healthy diet, and avoid alcohol to help lower your risk of bone loss.
