Liothyronine tablets and capsules

About liothyronine

If you have an underactive thyroid gland, it means that your thyroid does not produce enough thyroid hormone. This is a condition known as hypothyroidism. Liothyronine restores the balance of thyroid hormone in your body. It is similar to thyroxine, the hormone which your body produces naturally. Although a medicine called levothyroxine is usually prescribed in preference to liothyronine for people with this condition, liothyronine is given when a fast action is needed, as it works more quickly.

Before taking liothyronine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking liothyronine it is important that your doctor knows:

• If you have heart or blood vessel disease, or a high blood pressure.

• If you have either diabetes (diabetes mellitus) or diabetes insipidus.

• Si toma o utiliza otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

• Si alguna vez ha tenido una reacción alérgica a un medicamento.

How to take liothyronine

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about liothyronine and will also provide you with a full list of the side-effects which you could experience from taking it.

• Take liothyronine exactly as your doctor tells you to. It is usual for your doctor to give you a small dose (such as ½-1 tablet a day) when you first take liothyronine, and then for your dose to be gradually increased to two or three tablets daily, taken spaced out throughout the day.

• Take the tablets with a drink of water. You can take liothyronine either before or after meals.

• If you forget to take a dose, take it as soon as you remember. Try to take the correct number of doses each day but do not 'double up' to make up for any missed doses.

• Try to keep your regular appointments with your doctor so that your progress can be monitored. You will need regular blood tests to check your thyroid levels, particularly in the early stages of your treatment.

• Continue to take the tablets until your doctor tells you to stop.

• If you have diabetes you may need to check your blood glucose more frequently as these tablets can affect the levels of sugar in your blood. Your doctor will advise you about this.

• If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking liothyronine.
