What does “potassium citrate ER 15 mEq TB” mean?
“Potassium citrate ER 15 mEq” refers to an extended-release (ER) oral potassium citrate product where each tablet provides 15 milliequivalents (mEq) of potassium. “TB” usually means tablets.
This medication is used to increase urinary citrate and help alkalinize urine, most commonly in conditions like certain types of kidney stones (for example, uric acid stones and prevention of recurrent stones in some patients).
How do you take potassium citrate ER 15 mEq tablets?
The exact dosing schedule depends on the reason it was prescribed (stone prevention, urine alkalinization, etc.) and your kidney function. Follow the directions on the specific label.
Common general instructions (not a substitute for your prescription label) are:
- Take it by mouth with water.
- Do not crush or chew ER tablets unless your product’s instructions say it’s okay (extended-release forms are designed to release slowly).
- Take it consistently as directed, because urine chemistry depends on steady dosing.
What side effects should patients watch for?
Because it contains potassium, the main risk is too much potassium (hyperkalemia), which can be serious—especially in people with reduced kidney function or those taking certain interacting medicines.
Seek medical help urgently if you have symptoms like:
- Severe weakness or fatigue
- Numbness/tingling
- Slow or irregular heartbeat
- Shortness of breath
Common side effects can include gastrointestinal upset (such as nausea or stomach discomfort).
Who should be careful or ask a clinician before using it?
You need extra caution if any of the following apply:
- Kidney disease or poor kidney function
- A history of high potassium levels
- Use of medications that raise potassium (for example, certain blood pressure drugs like ACE inhibitors/ARBs, spironolactone/eplerenone, or potassium supplements)
- Conditions that increase risk of potassium retention
Drug interactions and safety checks
Potassium citrate can interact with other drugs that affect potassium or urine chemistry. If you tell me the other medicines you take, I can help identify likely interaction concerns to discuss with your pharmacist or prescriber.
How much is “15 mEq” in practical terms?
“15 mEq” is a measure of ionic charge. Clinically, the label uses mEq to define the potassium delivered per tablet rather than a weight like grams.
Can you share the exact product name or label?
If you paste what’s written on your bottle/box (including manufacturer name, strength format, and any instructions like “take ___ tablets ___ times daily”), I can translate the label more precisely and help you understand what “TB” and the 15 mEq ER dosing likely means for your prescription.
