Amiodarone is an antiarrythmic used to treat a life threatening heart condition known as ventricular and supraventricular arrhythmias, or abnormal heart rhythm. This medication is only given when all other medications have failed to control the arrhythmias. In the United States these drugs are marketed as Cordarone and Pacerone. The drug works by relaxing the heart muscle.
Proper Use
The Mayo Clinic reports that amioderone is an oral medication. The first dosage will be given in the hospital so that the physician can monitor reaction to the drug to make sure there are no serious side effects or allergic reactions. Dosages will vary according to each individual patient's needs and can be taken with or without food. Patients usually remain in the hospital for about a week while the drug is titrated and the proper therapeutic dosage is found.
Contraindications
According to Medic8.com, the only absolute contraindication is an allergy to the medication. Due to the numerous amount of potential side effects, a number of groups should be cautious about taking this medication. Pregnant women are strongly encouraged not to take it. However, if there is a life threatening heart condition, the risk of not taking the medication must be weighed against the potential effects on the unborn fetus. People with a decreased lung function should be monitored closely.
Special Precautions
Before taking amiodarone it is important to let your health care provider know if you are allergic to this medication, iodine or any other medications. Medline Plus, a publication of the National Institutes of Health, states that it is imperative that you let them know all medications you are currently taking including vitamins and herbal supplements. Amiodarone has a negative interaction with a number of drugs, some of which can be fatal.
Side Effects
According to the Mayo Clinic, amiodarone side effects can be life threatening and your health care professional should be alerted to any of the following: cough, dizziness, fainting, painful breathing, sensitivity to light, shortness of breath, trembling or shaking hands, trouble walking, unusual or uncontrolled body movements and weakness in the arms and legs. Less common effects can include seeing halos of light around objects and a blue green tint to the face, neck and arms. In rare instances liver damage may occur. It is important to let your doctor know immediately if your eyes or skin begin to appear yellow.
Considerations
There are a number of things to keep in mind while taking this medication. Do not eat grapefruit or drink grapefruit juice. Wearing a medical bracelet is recommended so that others are aware that you are taking this medication in an emergency situation. Always inform surgeons or dentists before undergoing any procedure. This medicine may cause permanent changes in your heart rhythm. The National Institutes of Health cautions patients to never stop taking the medication without consulting a physician. This can result in a hospitalization.
