If you missed a dose of Jardiance (empagliflozin), take it as soon as you remember, as long as your next scheduled dose is 12 or more hours away. If it's less than 12 hours until your next dose, skip it and take the next one on schedule. Never take two doses to make up for a missed one. One skipped dose of Jardiance is unlikely to cause a dangerous blood sugar spike.
Why a missed dose of Jardiance matters (but isn't an emergency)
Jardiance belongs to a class of drugs called SGLT2 inhibitors. Instead of pushing your body to produce more insulin, it works in your kidneys. It blocks a protein that normally reabsorbs glucose back into your blood, so more sugar leaves your body through urine.
Here's the reassuring part: Jardiance on its own does not typically cause low blood sugar (hypoglycemia). That's different from insulin or sulfonylureas, where a missed dose can mean a real blood sugar swing. With Jardiance, the main risk of skipping a dose is that your blood sugar runs higher than usual for the day. Your kidneys temporarily go back to reabsorbing glucose instead of flushing it out.
That said, consistency matters. Jardiance has a half-life of about 12.4 hours, meaning roughly half the drug is cleared from your body within half a day. By the time 24 hours pass without a dose, only about a quarter of the previous dose is still active. So while one missed dose isn't an emergency, regularly skipping doses undermines the protection Jardiance provides for your blood sugar, heart, and kidneys.
Adherence is a widespread challenge. A national cohort study found that about one-third of patients starting an SGLT2 inhibitor didn't fill their second prescription within 30 days. If you're finding it hard to stay on track, you're far from alone.
What to do when you forgot to take Jardiance
The Jardiance missed dose guidelines are straightforward, according to the NHS:
- Remembered early in the day? Take the missed dose now, as long as your next dose is 12 or more hours away. Then continue your regular schedule tomorrow.
- Remembered late, close to your next dose? Skip the forgotten dose. Take the next one at your normal time. Don't try to catch up by doubling.
- Not sure what to do? Call your pharmacist. They can tell you the best move based on how many hours remain before your next dose.
Why the 12-hour cutoff? Jardiance reaches peak levels in your blood about 1.5 hours after you take it. Taking two doses too close together means overlapping peak concentrations, which can increase the risk of side effects like dehydration and urinary tract infections without giving you extra blood sugar benefit.
How Jardiance works differently from other diabetes drugs
Most people with type 2 diabetes start with metformin, which works in the liver and gut. Jardiance takes a completely different approach, working in the kidneys. Some patients also take injectable medications like Ozempic (semaglutide), which works on the GLP-1 pathway. Each drug class has its own missed dose rules.
When you eat, glucose enters your bloodstream and gets filtered by your kidneys. Normally, a protein called SGLT2 reabsorbs almost all of that glucose back into your blood. Jardiance blocks that protein, so your kidneys excrete excess glucose through urine instead.
This mechanism is why Jardiance causes increased urination, which is a feature, not a bug. But it also explains why doctors typically recommend taking Jardiance in the morning. If you take it at night, the extra urination can disrupt your sleep.
The kidney-based mechanism is also why Jardiance has earned FDA approval for three different conditions: type 2 diabetes, heart failure, and chronic kidney disease. Removing excess glucose and sodium through urine reduces the workload on both the heart and kidneys.
Jardiance vs. metformin: missed dose comparison
If you take both Jardiance and metformin, here's how they compare when it comes to a missed dose of Jardiance versus a missed dose of metformin:
| Jardiance (empagliflozin) | Metformin | |
|---|---|---|
| Drug class | SGLT2 inhibitor | Biguanide |
| How it works | Blocks glucose reabsorption in kidneys | Reduces glucose production in liver |
| Typical dosing | Once daily (morning) | Twice daily (with meals) |
| Half-life | ~12.4 hours | ~6.2 hours |
| Missed dose rule | Take if 12+ hours until next dose | Take as soon as you remember; skip if almost time for next dose |
| Causes low blood sugar alone? | No | No |
| Key side effect to watch | Increased urination, UTIs, genital yeast infections | GI upset (nausea, diarrhea) |
| Take with food? | With or without food | With meals (reduces stomach upset) |
If you're managing both medications plus others, the timing can get complicated. Our guide on managing multiple medications without missing doses breaks down practical strategies for keeping everything on schedule.
Why morning dosing matters for Jardiance
Your doctor probably told you to take Jardiance in the morning. There's a good reason.
Jardiance increases how much glucose and fluid your kidneys flush out. That translates to more frequent urination, sometimes significantly more. Taking it in the morning means most of this extra activity happens during the day when you're awake and near a bathroom. Taking it at bedtime can mean multiple trips to the bathroom overnight.
The extra urination also carries a risk of dehydration, especially in hot weather or if you're not drinking enough water. Morning dosing gives you the full day to stay hydrated.
There's another timing-related side effect worth knowing about. Jardiance can cause urinary tract infections and genital yeast infections because the extra sugar in your urine creates an environment where bacteria and yeast thrive. Good hydration and hygiene habits throughout the day help reduce this risk, and that's easier to manage when the drug is active during waking hours.
When to call your doctor about a missed dose of Jardiance
A single missed dose of Jardiance usually isn't a reason to call your doctor. But reach out if:
- You're missing doses often. If the timing is hard to stick with, your doctor may be able to adjust your routine. Consistent dosing is important for Jardiance to protect your heart and kidneys, not just manage blood sugar.
- Your blood sugar stays high for more than a day. One missed dose shouldn't send your blood sugar dangerously high. If it does, something else may be going on.
- You notice signs of a UTI or yeast infection. Burning during urination, unusual discharge, or pelvic pain after restarting Jardiance warrants a call.
- You feel unusually weak, nauseated, or short of breath. These could be signs of diabetic ketoacidosis (DKA), a rare but serious complication of SGLT2 inhibitors. DKA can happen even when blood sugar looks normal, which is unusual and easy to miss.
- You want to stop taking Jardiance. Don't stop on your own. Talk to your doctor about alternatives or adjustments first.
How to stop forgetting your Jardiance dose
The upside of Jardiance is that it's once a day, no food restrictions, no waiting period. That makes it easier to build a habit than medications like omeprazole that require empty-stomach timing.
The simplest approach: pair it with something you already do every morning. Put the bottle next to your toothbrush, your coffee maker, or your phone charger. Take it at the same time each day, and it becomes automatic.
If that isn't enough, Pillo uses persistent alarms that won't stop until you acknowledge them. No more silencing a notification and then forgetting anyway. It also tracks your medication history, so on days when you can't remember if you took your medication, you can check instead of guessing. For a once-daily medication like Jardiance, knowing whether you already took today's dose prevents accidental double-dosing.
FAQ
What happens if you miss Jardiance for one day?
Your blood sugar may run slightly higher than usual, but one missed day is unlikely to cause a serious problem. Unlike insulin, Jardiance does not cause hypoglycemia on its own, so you won't experience a dangerous low from missing it. Take your next dose at the normal time and continue your schedule.
Can I take Jardiance at night if I forgot it in the morning?
You can, as long as your next morning dose is 12 or more hours away. Just be aware that Jardiance increases urination, and taking it at night may mean extra bathroom trips while you're trying to sleep. If you find yourself regularly taking a late Jardiance dose, talk to your doctor about whether an adjusted schedule makes sense.
Does missing Jardiance cause high blood sugar?
A missed dose of Jardiance can cause a temporary rise, but not a dramatic spike in most people. Jardiance works by removing excess glucose through urine. When you miss a dose, your kidneys go back to reabsorbing that glucose. If you're taking other diabetes medications alongside Jardiance, those continue working even when Jardiance is missed.
Is Jardiance the same as metformin?
No. They're completely different drugs that work through different mechanisms. Metformin reduces glucose production in your liver, while Jardiance blocks glucose reabsorption in your kidneys. Many people take both together. Their missed dose rules differ because they have different half-lives and side effect profiles. See the comparison table above for details.
Can you take two Jardiance pills if you missed yesterday's dose?
No. Never double up on Jardiance. Taking two doses at once increases the risk of dehydration, urinary tract infections, and other side effects without providing meaningful extra blood sugar control. If you missed yesterday's dose, just take today's dose at the normal time and move on. If you're unsure, your pharmacist can advise.
