The NHS has issued an alert to anyone taking levothyroxine for their thyroid condition. With approximately 33 million prescriptions of levothyroxine dispensed across the UK annually, the medication ranks among the most frequently prescribed drugs by the NHS.
It is routinely used to manage an underactive thyroid gland, also referred to as hypothyroidism. Usually, it will be administered as either a tablet or liquid form that patients consume, based on what the GP deems most appropriate.
While levothyroxine proves effective in treating an underactive thyroid in the majority of cases, the NHS has cautioned that certain individuals should not be prescribed the medication.
This can be due to various factors, including the drug potentially heightening the risk of complications from other medical conditions. The NHS website states: “Levothyroxine can be taken by most adults and children. However, it’s not suitable for some people.”
People who may not be able to take levothyroxine
According to NHS guidance, you may not be able to take levothyroxine if one of the following applies:
- You have a heart problem, including angina, heart disease or heart failure
- You have a health problem that affects your adrenal glands
- You have previously had a heart attack
- You have an overactive thyroid that produces too much thyroid hormone (thyrotoxicosis)
- You have diabetes
- You have previously had an allergic reaction to levothyroxine or any other medicine
- You have high blood pressure
When to call 999
Levothyroxine can cause a wide array of side effects, some of which may warrant a call to 999 or a visit to A&E. Common side effects of levothyroxine include:
- Flushing or sweating
- Feeling restless or excitable
- Trouble sleeping
- Nausea
- Headaches

- Muscle cramps
Bear in mind that there could be additional side effects linked to levothyroxine not mentioned above. For a comprehensive list of potential side effects, refer to the leaflet included with your medication.
While these common side effects can be uncomfortable, they’re typically not severe and don’t require emergency medical attention. However, if they persist, the NHS recommends consulting a doctor or pharmacist for professional advice.
If you experience a rapid or irregular heartbeat, it’s crucial to contact a doctor or dial 111 immediately. Moreover, if you suffer from chest pains while on levothyroxine, you should call 999 without delay.
