Eltroxin

Eltroxin is a medication used to treat an underactive thyroid gland (also known as hypothyroidism). When a patient’s thyroid gland fails to produce as much of the hormone thyroxine as it normally should, this treatment can be taken to top up levels of this hormone, quashing symptoms caused by hypothyroidism.

What is Eltroxin?

Eltroxin tablets are used to treat symptoms caused by an underactive thyroid gland, a condition also known as thyroid hormone deficiency or hypothyroidism. The drug increases the amount of the hormone thyroxine that is in the body when it is at a lower-than-normal level due to hypothyroidism. The tablets are available in a few different strengths to suit the different dosages that may be required for your body during treatment.

How does Eltroxin work?

Eltroxin contains levothyroxine sodium, which is a synthetic version of the hormone thyroxine. People naturally produce thyroxine from their thyroid gland which is located in the neck. When someone has an underactive thyroid gland, it means it is not producing as much thyroxine as it should, causing many of the body’s functions to slow down. This can lead to symptoms such as tiredness, weight gain and feeling depressed. By replacing the thyroxine your gland cannot produce, Eltroxin prevents the symptoms of hypothyroidism from developing.

How do I take Eltroxin?

You should always take these tablets according to your prescriber’s instructions. These tablets are available in strengths of 25mcg, 50mcg and 100mcg. For adults aged below 50, the typical starting dose is 50-100mcg every day. Your doctor may increase your dose every 3-4 weeks until your thyroxine levels are correct. Your daily dosage may end up becoming 100-200mcg.

For adults over 50, the recommended starting dose is 50mcg every day. Over time, the daily dose may go up to 200mcg in total if required. If you’re over 50 and have heart problems, however, then the recommended dose goes down to just 25mcg every day or 50 mcg every other day. The dose may be increased by 25mcg every four weeks until your thyroxine levels are correct.

What are the side effects of Eltroxin?

There are various side effects which could occur when using Eltroxin, although you may not experience any side effects at all. Most of the side effects which could potentially occur are similar to the symptoms of hyperthyroidism – a condition that occurs when your thyroid gland is producing too much of the hormone thyroxine. This will likely be due to your dose of medicine being too high. The symptoms will usually disappear not long after reducing your dose or stopping the tablets. However, neither action should be taken before talking to your doctor first.

In rare cases, a serious allergic reaction may occur while taking Eltroxin and you should contact your doctor or nearest hospital emergency department if you experience symptoms that indicate this. Difficulty breathing, a very high temperature or swelling around the face, mouth or throat are all common signs of an allergic reaction. Such a reaction may be caused by having high levels of thyroxine in your body (a condition known as a “thyroid crisis”).

The following have also occasionally been reported as side effects one can experience while taking Eltroxin:

  • Headaches
  • Flushing
  • Weight loss
  • Restlessness
  • Chest pain
  • Diarrhoea and vomiting
  • Muscle cramps
  • Irregular periods
  • Can I use Eltroxin?

    Before you begin using this medication, it’s important to tell your doctor or pharmacist about health conditions you have which may need to be factored in, as well as medications you are taking or have recently used. You will also need to have a blood test so your doctor can determine what dose of the medicine is needed. Your doctor will want to take regular blood tests after you start the medication to see how well it is working.

    You should avoid using Eltroxin if you have a condition that affects your adrenal glands, you could speak to your doctor for advice if you are not sure about this. As a precaution, you should also highlight these health conditions if any apply to you:

    • Heart problems such as angina, high blood pressure or coronary artery disease
    • Diabetes
    • You have suffered with an underactive thyroid gland for a long time
    • You’re pregnant, breastfeeding or think you may be pregnant
