Yes, you can take metoprolol on an empty stomach, and for most people taking it, nothing bad will happen. But the two versions of metoprolol play by different rules. Immediate-release metoprolol tartrate (Lopressor) absorbs better and more consistently when you take it with food, so its FDA label says to take it with or right after meals. Extended-release metoprolol succinate (Toprol-XL) absorbs the same whether you eat or not.
So the real question is not "is it safe to skip the meal." It is "which metoprolol do I have, and am I taking it the same way every day?"

First, Check Which Metoprolol You Take
The word on your pharmacy label matters more than the meal on your plate.
| Metoprolol tartrate (Lopressor) | Metoprolol succinate (Toprol-XL) | |
|---|---|---|
| Release type | Immediate-release, usually twice a day | Extended-release, once a day |
| Does food change absorption? | Yes. Food increases how much of the dose your body absorbs | No. The FDA label says absorption is "not significantly affected by food" |
| What the FDA label says | "Preferably be administered with or following meals" | "Preferably with or immediately following meals," mainly to anchor a daily routine |
| Empty stomach once in a while | Fine for most people, but you may absorb a bit less than usual | Fine, no meaningful difference |
| What matters most | Doing it the same way every day | Taking it every day, period |
Why Food Changes One Version and Not the Other
Metoprolol tartrate has a quirk: your liver breaks down a big share of each dose before it ever reaches your bloodstream. The Lopressor prescribing information puts oral bioavailability at only about 50% because of this first-pass metabolism. Eating changes how fast the drug moves through your gut and liver. A 1977 study in Clinical Pharmacology and Therapeutics found that taking metoprolol with a standardized breakfast increased the amount reaching the blood compared with taking it fasted, and that absorption varies a lot from person to person.
That is why "with or after meals" is on the tartrate label. It is not about protecting your stomach. It is about getting a similar amount of medication into your blood at every dose.
Toprol-XL smooths this out. Its extended-release tablet lets go of metoprolol slowly over the day, and the Toprol-XL label states absorption "is not significantly affected by food." A pharmacokinetic study in the British Journal of Clinical Pharmacology tested an extended-release metoprolol system fasting and around three different meals and found the blood concentration profiles were "virtually identical" in all four conditions.
If you want the full picture on timing (morning vs night, tartrate vs succinate schedules), that lives in our guide to the best time to take metoprolol.
Already Took It on an Empty Stomach? Do This
Nothing. You are almost certainly fine.
Do not take a second dose to "make up" for the meal you skipped. MedlinePlus is blunt about this for missed doses, and the same logic applies here: never double up. If anything, taking tartrate fasted means slightly less medication absorbed, not more. Taking an extra pill is how people end up reading our article on accidentally taking a double dose of metoprolol.
Two situations are worth a call to your pharmacist:
- You take tartrate and your eating schedule has completely changed (new job, fasting, illness). Absorption swings could make your response less predictable.
- You feel dizzy or lightheaded after a fasted dose. Sit down until it passes. If it is severe, or it does not pass, call your doctor or pharmacist right away instead of waiting. Beta-blockers lower blood pressure and heart rate, and everyone responds a little differently.
And if the empty stomach happened because you skipped breakfast and then forgot the pill entirely, that is a different problem: see what to do about a missed metoprolol dose.
One more thing you should never do with metoprolol: stop taking it because the food rules feel like a hassle. The Lopressor label warns that after abrupt cessation of certain beta-blockers, chest pain has worsened and, in some cases, heart attacks have occurred. Any change should go through your doctor.
The Real Rule: Same Way, Every Day
Notice what both labels agree on: consistency. "With or following meals" is really an anchoring trick. A pill tied to breakfast is a pill you take at roughly the same time, in roughly the same way, every single day. For steady blood pressure control, that day-to-day consistency is the part you can actually control, which is the same reason switching your blood pressure medication timing should be done deliberately, not randomly.
Pillo handles the routine part. Set your metoprolol reminder for your usual breakfast or dinner time, and the persistent alarm keeps ringing until you log the dose. No more "did I take it before or after I ate, or at all?" If your household juggles blood pressure pills alongside other prescriptions, our guide on foods to avoid with blood pressure medications covers what actually interacts.
FAQ
Should metoprolol be taken with food?
Ideally, yes. The FDA label for metoprolol tartrate (Lopressor) says it should "preferably be administered with or following meals" because food increases and steadies absorption. For metoprolol succinate (Toprol-XL), food does not meaningfully change absorption, but taking it with a regular meal is still a useful habit anchor.
What happens if I take metoprolol tartrate on an empty stomach?
For most people, nothing noticeable. Your body may absorb somewhat less of the dose than it would with food, and absorption varies more from person to person when fasted. An occasional fasted dose is not dangerous, but taking it differently every day makes your levels less predictable. Pick one pattern and stick to it.
Does Toprol-XL need to be taken with food?
No. The Toprol-XL prescribing information states that absorption is not significantly affected by food. The label still suggests taking it with or right after a meal, mainly because tying the pill to a daily routine helps you not miss it.
Can I take metoprolol with just a snack instead of a full meal?
Yes. There is no rule requiring a full meal. For tartrate, having something in your stomach at roughly the same time each day is the point. What counts as an "empty stomach" is fuzzier than most people think; our guide on what taking medication on an empty stomach means breaks down the actual time windows.
Should I skip my metoprolol dose if I have not eaten?
No. An empty stomach is not a reason to skip a dose. Neither FDA label makes food a requirement, and a fasted dose does far more for you than a missed one. If you know you will not be able to eat for a longer stretch (illness, fasting, a procedure), ask your pharmacist ahead of time how to handle your schedule.
Is it better to take metoprolol in the morning or at night?
It depends on your formulation and why you take it. That question has its own full guide: best time to take metoprolol. Whatever time you choose, take it consistently. Metoprolol is one of many medications where food timing rules matter less than a steady routine.
