Canagliflozin: What It Is and How It Works
If you’ve been told to take canagliflozin, you probably wonder why a pill that sounds like a tongue‑twister could help your health. In plain terms, canagliflozin is an oral drug that belongs to the SGLT2 inhibitor class. It tells your kidneys to let more sugar leave your body through urine, which lowers blood glucose levels over time. The result is better control of type 2 diabetes without having to inject insulin.
When Do Doctors Prescribe Canagliflozin?
Most doctors add canagliflozin when diet and exercise alone aren’t enough to keep A1C numbers in range. It’s also an option if you’re already on metformin or another oral agent but need extra help. Some specialists even use it for people with kidney disease or heart failure because studies show it can protect the kidneys and reduce cardiovascular risk.
Typical patients are adults with type 2 diabetes who have a decent kidney function (eGFR above 30 mL/min/1.73 m²). If you have severe kidney problems, your doctor might choose another medication instead.
How to Take Canagliflozin – Dosage Basics
The standard starting dose is 100 mg once a day with or without food. After a few weeks, if your blood sugar is still high and you tolerate the drug well, the doctor may increase it to 300 mg daily. Some people split the dose—taking one tablet in the morning and another at night—to smooth out any bathroom trips.
Never crush or chew the tablets; they’re designed to dissolve slowly. If you miss a dose, take it as soon as you remember unless it’s almost time for your next pill – then just skip the missed one. Consistency is key because the drug works best when there’s steady exposure in your system.
Common Side Effects and What to Watch For
Canagliflozin can cause a few predictable side effects. The most frequent are increased urination, mild yeast infections (especially in women), and occasional dizziness from low blood pressure. These usually fade after the first couple of weeks.
A rarer but serious issue is diabetic keto‑acidosis (DKA). If you feel nausea, stomach pain, rapid breathing, or unusual fatigue, call your doctor right away—even if your blood sugar isn’t sky‑high. Another warning sign is a sudden drop in weight or persistent low blood pressure; that could mean you’re losing too much fluid.
Key Tips for Safe Use
Stay hydrated. Because the drug pushes extra fluid out, drink plenty of water throughout the day, especially if you exercise or live in a hot climate.
Check your blood sugar regularly. Even though canagliflozin lowers glucose, you still need to monitor levels to avoid lows when combined with other diabetes meds.
Watch for infections. If you notice itching, burning, or abnormal discharge, schedule a quick check‑up; early treatment stops problems from getting worse.
Talk to your pharmacist about any over‑the‑counter supplements or herbal products. Some can interfere with kidney function and make the drug less effective.
