What is Levothyroxine?

Levothyroxine is a generic treatment for an underactive thyroid (known as hypothyroidism in medical terms). Having an underactive thyroid means that your thyroid gland doesn’t produce enough hormones which can lead to tiredness, weight gain and mood changes. There’s no way to prevent an underactive thyroid – most cases are thought to be caused by an immune disorder or a damaged thyroid from other treatments.

Levothyroxine works like replacement therapy. It stops you from experiencing the symptoms of hypothyroidism which can affect your body, energy and mood. It does this by replacing a hormone that’s normally produced by your thyroid.

Hypothyroidism is thought to affect women much more than men. According to NHS Scotland, 1 in 1,500 men are diagnosed with it, compared to 15 in 1,000 women. Approximately 3.05% of people in Europe have diagnosed hypothyroidism. Levothyroxine is one of the most widely prescribed medications in the world and is considered to be an essential medicine for basic health care, according to the World Health Organization.

How does Levothyroxine work?

This medication has a hormone in it called Levothyroxine. It’s used to replace a natural hormone called thyroxine, which your body doesn’t produce enough of if you have hypothyroidism. When these hormone levels are restored with Levothyroxine, it tackles hypothyroidism symptoms too.

Levothyroxine works straight away, but it can take longer for your symptoms to start to improve as your body adjusts to the medication. Your clinician can tell you if you’re taking the right dose based on your symptoms. If you stop taking Levothyroxine your symptoms are likely to come back.

What doses of Levothyroxine are there?

There are 25mg, 50mg and 100mg doses of Levothyroxine tablet. But you can also get it as an oral solution in concentrations of 25mcg, 50mcg and 100mcg per 5ml. The right dose for you depends on the results of a blood test that you’ll need to have to measure your thyroid levels, your age, lifestyle and health. If you’ve had Levothyroxine on prescription before, our clinician can use this to make sure you get the dose you need.

How to take Levothyroxine

You should always take note of what dose of Levothyroxine you have been prescribed by your clinician. You may need to take more than one tablet to make up your dose, or your dose may increase over time. It’s important to familiarise yourself with how much Levothyroxine you should be taking.

Here’s how to take Levothyroxine:

  • Take Levothyroxine once a day in the morning, before you have breakfast or drink caffeinated drinks (such as your morning tea or coffee).
  • If you’re taking the tablets, swallow these whole with a drink of water.

If you find it difficult to swallow tablets, it is available as a liquid to make taking Levothyroxine easier. This will come with a measuring spoon or plastic syringe to help you ensure that you measure out the right dose.

  • Shake the bottle first.
  • Remove the cap from the bottle.
  • Insert the adapter provided into the bottle.
  • Take the plunger, making sure the handle is fully down.
  • Keeping the bottle vertical, place the syringe into the adapter.
  • Turn the bottle and syringe so the bottle is on top and the syringe upside down beneath.
  • Pull the plunger down to full the syringe with the solution.
  • Push back up fully to get rid of any air bubbles.
  • Then pull the plunger down again to get the correct amount of medication.
  • Turn the bottle right way up with the syringe still in.
  • Take the syringe out, and replace the cap on the bottle (leaving the adapter on).
  • Sit upright and, using the syringe, deliver the solution into your mouth and swallow.

How long does it take Levothyroxine to work?

It can take a few weeks of using the treatment to start feeling relief from the symptoms of hypothyroidism, such as being tired, gaining weight or feeling depressed, as your body adjusts to the medication.

What should I do if I make a mistake when taking Levothyroxine?

If you forget to take your dose, you should take it as soon as you remember, but not if it’s nearly time for the dose that follows. You shouldn’t take twice the amount to make up for a missed dose. If you’re uncertain of what to do if you make a mistake with Levothyroxine, drop our clinician a message, and they can chat to you about it.

Food and caffeinated drinks can stop your body taking in Levothyroxine properly so it may not work as well. That’s why it’s important to remember to take it before you eat or drink in the morning.

How we source info.

When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body.

FAQ: Levothyroxine

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How is Levothyroxine different to other treatments for hypothyroidism?

Answer:
Levothyroxine contains thyroxine which is a ‘T4 hormone’, but there is another treatment called Liothyronine which is a T3 hormone. If you’re finding it difficult to get the right balance of thyroxine with Levothyroxine, you may be better suited to Liothyronine. You can discuss this with our clinician if you feel that Levothyroxine isn’t working as well for you.

Is Levothyroxine similar to any other treatments?

Answer:
Levothyroxine is the generic version of Eltroxin, so it works in the same way. But the packaging and the way the tablets look may be different, and Levothyroxine is slightly cheaper as the generic option. A generic option just means that it isn’t a branded version of a medication but it still works as effectively as brand name versions of Levothyroxine such as Eltroxin.

Which dose of Levothyroxine should I use?

Answer:
You can get Levothyroxine as a 25mg, 50mg or 100mg tablet, and these can be used to give ‘in-between’ doses. The dose you use depends on what the results of your blood test are, but it can also depend on what symptoms you get, your age, your hormone levels and if you have any other health problems. Our clinician can help you to find the right dose just for you.

Do I need a prescription for Levothyroxine?

Answer:
Yes. So you’ll need to have a conversation with our clinician before you can get it, so that they can make sure that it’s safe for you to use. Levothyroxine isn’t available on subscription, but will instead be available as a repeat prescription that can be ordered as needed. We’ll check in on you regularly to make sure that you’ve got the medication that you need.

Why should I buy Levothyroxine online with Treated?

Answer:
With Treated, it’s easy to get the treatment that you need. Our specialist clinicians are always available to help you with your Levothyroxine prescription, including making sure you have the right dose to manage your symptoms and that you feel like it’s helping you.

We’ll also check in with you to ensure that your treatment is working. We’ll also send you reminders to make sure that you have enough treatment, and that you don’t run out.
