Amiodarone (Cordarone X): reminder of risks of treatment and need for patient monitoring and supervision

March 2022 - Amiodarone is used to treat certain types of abnormal heart rhythm, including atrial fibrillation and tachyarrhythmias (heart beats unevenly or too fast). Treatment should be initiated under hospital or specialist supervision and in accordance with clinical guidance.

Amiodarone is associated with serious adverse effects in several organ systems including the eyes, gastrointestinal tract, nerves, skin, thyroid, lungs, heart, and liver. Amiodarone has a long plasma half-life of around 50 days, meaning that any adverse effects may persist for a month (or more) after treatment has stopped. Patients must be monitored closely during treatment

Advice for patients and carers:

Always read the patient information leaflet provided with your medicines and follow the advice on other medicines to avoid and what to do if you have a side effect.

Your doctor may perform tests of your blood, lungs, heartbeat, and eyes before and during treatment – it’s important to have these tests because they can identify if there’s a problem. During treatment blood tests are advised every 6 months.

Stop taking amiodarone and see a doctor or go to a hospital straight away if you experience any of the following during treatment or in the period after stopping amiodarone:

New or worsening shortness of breath or coughing that will not go away
Yellowing of the skin or eyes (jaundice), feeling tired or sick, loss of appetite, stomach pain, or high temperature
Weakness, weight loss or weight gain, heat or cold intolerance, hair thinning, sweating, changes in menstrual periods, swelling of the neck (goitre), nervousness, irritability, restlessness, or decreased concentration
Your heartbeat becomes even more uneven or erratic, or becomes very slow
Any loss of eyesight

NHS Emergency Steroid card

September 2020 - Recently issued National guidance promotes a patient-held Steroid Emergency Card to help healthcare staff identify patients with adrenal insufficiency and provide information on emergency treatment.

This means that there are now 2 types of steroid alert card a patient may be required to carry:

1. A steroid TREATMENT card (blue card)

This carries a series of instructions for the patient and informs healthcare professionals to whom the patient shows the card. The card should be carried when a patient is taking ORAL steroids. Patients taking oral corticosteroids for periods of more than three weeks should receive a steroid treatment card, or those receiving more than four short oral courses per year.

2. A steroid EMERGENCY card

Is a prompt to help healthcare staff to identify appropriate patients and gives information on the emergency treatment to start if they are acutely ill, or experience trauma, surgery or other major stressors.

The steroid emergency card should be given to all patients with primary adrenal insufficiency and those who are steroid dependent (on a long-term oral steroid).

Cards are available through community pharmacies or The card can be downloaded from the Society for Endocrinology adrenal crisis webpage.

Hydrochlorothiazide: risk of non-melanoma skin cancer, particularly in long-term use

November 2018 - Studies have shown a dose-dependent increased risk of non-melanoma skin cancer with exposure to increasing cumulative doses of Hydrochlorothiazide (contained in some combination products used for high blood pressure). Patients taking Hydrochlorothiazide should:

Regularly check for and report any new or changed skin lesions or moles
Limit their exposure to sunlight and UV rays and use adequate protection when exposed to sunlight and UV rays to minimise the risk of skin cancer
Make an appointment to discuss alternative options to the use of hydrochlorothiazide if you would like to and particularly if you have had a previous skin cancer.
