POTASSIUM IODIDE - ORAL

PHONETIC PRONUNCIATION: (poh-TASS-ee-um EYE-oh-dyed)

COMMON BRAND NAME(S): SSKI

GENERIC NAME(S): potassium iodide

Uses

USES: Potassium iodide is used to loosen and break up mucus in the airways. This helps you cough up the mucus so you can breathe more easily if you have long-term lung problems (e.g., asthma, chronic bronchitis, emphysema). This medication is known as an expectorant. Potassium iodide is also used along with antithyroid medicines to prepare the thyroid gland for surgical removal, to treat certain overactive thyroid conditions (hyperthyroidism), and to protect the thyroid in a radiation exposure emergency. It works by shrinking the size of the thyroid gland and decreasing the amount of thyroid hormones produced. In a radiation emergency, potassium iodide blocks only the thyroid from absorbing radioactive iodine, protecting it from damage and reducing the risk of thyroid cancer. Use this medication along with other emergency measures that will be recommended to you by public health and safety officials (e.g., finding safe shelter, evacuation, controlling food supply).


How to use POTASSIUM IODIDE - ORAL

HOW TO USE: Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) as directed by your doctor or public health and safety officials. To avoid stomach upset, take after meals or with food. Drink plenty of liquids with this medication unless otherwise directed. If you are taking the tablets, do not lie down for at least 10 minutes after taking this medication. If you are using the drops or liquid medication, use the dropper that comes with the bottle or a medication spoon/device to measure the correct dose. Liquid forms of this product may be mixed in water, milk, formula, or juice before taking. Do not use this medication if the solution turns brownish-yellow. Dosage is based on your medical condition and response to therapy. In children, dosage is also based on age. Do not increase your dose, take it more often, or take it for longer than prescribed or recommended because of the increased risk of side effects. In a radiation emergency, take this drug only when public health and safety officials tell you to do so. Read the Patient Information Leaflet that comes with the medication. Start treatment as soon as possible for the best protection. Take this medication usually once every 24 hours. The length of treatment will be determined by public health and safety officials and depends on several factors (e.g., whether you continue to be exposed to the radiation, and whether you are pregnant, breast-feeding, or have a newborn baby). See also Precautions. If so directed, use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Inform your doctor if your condition persists or worsens.

Side Effects

SIDE EFFECTS: Nausea, vomiting, stomach ache, diarrhea, metallic taste in the mouth, fever, headache, or acne may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if any of these unlikely but serious side effects occur: burning mouth/throat, sore teeth/gums, swelling inside the mouth, increased saliva, eye irritation/swollen eyelids, severe headache, swelling of the front of the neck/throat (goiter), signs of decreased thyroid gland function (e.g., weight gain, cold intolerance, slow/irregular heartbeat, constipation, unusual tiredness), confusion, numbness/tingling/pain/weakness of the hands/feet. Seek immediate medical attention if any of these rare but very serious side effects occur: chest pain, black stools, vomit that looks like coffee grounds, bloody diarrhea. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, fever with joint pain. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

PRECAUTIONS: Before taking potassium iodide, tell your doctor or pharmacist if you are allergic to it; or to iodine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: current attack/worsening of bronchitis (if taking potassium iodide to thin mucus in the lungs), a certain type of skin condition (dermatitis herpetiformis), a certain type of blood vessel disease (hypocomplementemic vasculitis), nodular thyroid disease with heart disease. Before using this medication, tell your doctor or pharmacist your medical history, especially of: certain thyroid disorders (e.g., multinodular goiter, Graves' disease, autoimmune thyroiditis), overactive thyroid disease (unless you are specifically prescribed potassium iodide to treat hyperthyroidism), tuberculosis, high potassium blood level, kidney disease, Addison's disease, a certain muscle disorder (myotonia congenita). Caution is advised when this drug is given to newborn babies younger than 1 month old. Treatment for more than 1 day should be avoided because repeated dosing increases the risk of blocking thyroid function, possibly affecting the newborn's brain development. If treatment is needed for longer than 1 day, discuss the risks and benefits with the doctor. Treated babies should be given thyroid function tests. During pregnancy, this medication should be used only when clearly needed. Treatment for more than 1 day should be avoided because repeated dosing increases the risk of blocking thyroid function in the unborn baby, possibly causing harm. If treatment is needed for longer than 1 day, discuss the risks and benefits with your doctor. Caution is advised when this drug is used by women who are breast-feeding. This drug passes into breast milk. Treatment for more than 1 day should be avoided if you are breast-feeding because repeated dosing increases the risk of blocking thyroid function in the nursing infant. This effect may cause harm, especially in newborns younger than 1 month old. If treatment is needed for longer than 1 day, discuss with your doctor the risks and benefits, as well as whether you should stop breast-feeding.
