What side effects are associated with Invokana (canagliflozin)?
Invokana (canagliflozin) is a diabetes medicine (an SGLT2 inhibitor). Side effects most commonly reported with SGLT2 inhibitors include:
- Genital yeast infections (more common in people with a history of these infections), such as vaginal yeast infections or balanitis.
- Urinary tract infections.
- Increased urination or signs of dehydration (for some people), such as dizziness or low blood pressure.
More serious or less common risks can include:
- Diabetic ketoacidosis (DKA), including “euglycemic” DKA (DKA with not-very-high blood sugar).
- Serious volume depletion (dehydration) that can lead to fainting or kidney injury.
- Lower-limb complications (for some patients), including ulcers or infections that may lead to amputation risk signals seen with this drug class.
- Bone fractures (a noted risk signal for canagliflozin compared with some comparators in clinical data).
- An increased risk of needing treatment for acute kidney problems in certain settings.
Because side effects vary by dose, other medications, and patient risk factors, the most accurate list (including frequency) is the Prescribing Information.
When should you get urgent help after taking Invokana?
Get urgent medical care if you develop symptoms that can signal DKA or severe dehydration, such as:
- Nausea, vomiting, abdominal pain, trouble breathing, unusual sleepiness, or rapid breathing, especially if you feel ill even if blood sugar is not very high.
- Fainting, severe dizziness, or signs of marked dehydration.
- Severe pain, redness, swelling, sores, or infection on the foot or lower limb.
What side effects are most common—and who is more likely to get them?
Genital yeast infections are among the more common issues, especially in people prone to yeast infections. People who are older, take diuretics or blood-pressure medicines, or have conditions that increase dehydration risk may be more likely to experience dizziness or low blood pressure effects.
Does Invokana interact with other drugs that can raise side-effect risk?
Yes. Side effects can become more likely or more severe when Invokana is combined with certain therapies, particularly those that also lower blood pressure or affect kidney function. Your prescriber can check your medication list for interaction risk and advise monitoring.
If you tell me what other medicines you take (and your dose of Invokana), I can help you identify which side effects to watch for most closely.
How do you reduce the risk of side effects while on Invokana?
Common practical risk-reduction steps doctors use with SGLT2 inhibitors include:
- Staying well hydrated.
- Monitoring for genital symptoms early and treating promptly.
- Reviewing DKA risk during illness, fasting, heavy alcohol intake, surgery, or very low-carbohydrate intake (these can raise risk).
- Monitoring kidney function as directed.
Your clinician should give you “sick day” and monitoring instructions specific to your health situation.
