What should I watch for while taking amiodarone?
Your condition will be monitored closely when you first begin amiodarone therapy. Often, this drug is first started in a hospital or other monitored health care setting.
Amiodarone can cause serious side effects including significant lung damage, liver damage, vision changes, thyroid dysfunction, skin problems, and potentially heartbeat problems. It is very important to have regular checks with your health care professional. Notify your prescriber immediately if you notice symptoms that are listed in the side effects section, or any other persistent problems or unusual reactions. Amiodarone can be present in the body for a long time (months); some side effects may persist for a time after treatment is stopped.
Once you are on maintenance therapy, visit your prescriber or health care professional for regular checks on your progress. Check with your prescriber or health care professional if you develop a cough or have any difficulty breathing. Because your condition and use of this medicine carry some risk, it is a good idea to carry an identification card, necklace or bracelet with details of your condition, medications, and prescriber or health care professional.
You may get dizzy; to avoid a sudden drop in blood pressure and fainting spells, do not stand or sit up quickly, especially if you are an older person, until you know how amiodarone affects you.
Amiodarone can make your skin more sensitive to the sun. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen. Do not use sun lamps or sun tanning beds or booths.
You should have regular eye exams before and during treatment with amiodarone. Call your doctor if you have blurred vision, see halos, or your eyes become sensitive to light, or experience other changes in vision. Your eyes may get dry while you are using amiodarone. It may be helpful to use a lubricating eye solution or artificial tears solution.
If you are going to have surgery tell your prescriber or health care professional that you are taking amiodarone.
