potassium bicarbonate-citric acid

COMMON BRAND NAME(S): Effer-K, K-Lyte

GENERIC NAME(S): POTASSIUM BICARBONATE/CITRIC ACID

Uses

This medication is a mineral supplement used to treat or prevent low amounts of potassium in the blood. A normal level of potassium in the blood is important. Potassium helps your cells, kidneys, heart, muscles, and nerves work properly. Most people get enough potassium by eating a well-balanced diet. Some conditions that can lower your body's potassium level include severe prolonged diarrhea and vomiting, hormone problems such as hyperaldosteronism, or treatment with "water pills"/diuretics.

How to use potassium bicarbonate-citric acid

Take this medication by mouth as directed by your doctor, usually 1 to 4 times daily. To prevent stomach upset, take each dose with a meal. Dissolve the prescribed number of tablets in at least 4 ounces (120 milliliters) of cold water or juice per tablet. After the tablets are fully dissolved, sip the liquid slowly over 5 to 10 minutes. If you have upset stomach, mixing your dose in a larger amount of liquid may help.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. The dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than prescribed.

Tell your doctor if your condition does not improve or if you have symptoms of low potassium in the blood (such as irregular heartbeat, muscle weakness/cramps).

Side Effects

Upset stomach, nausea, vomiting, gas, or diarrhea may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because 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.

Get medical help right away if you have any very serious side effects, including: vomit that looks like coffee grounds, stomach/abdominal pain, black/tarry stools.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Notes
