The best time to take metoprolol depends on which form you take. Metoprolol tartrate (immediate-release) is taken twice daily with meals, morning and evening. Metoprolol succinate (extended-release) is taken once daily, morning or evening, whichever time you can stick with consistently.
Why Timing Depends on Your Metoprolol Form
"Take metoprolol once or twice daily" is the instruction most people get. But which applies to you? It depends on whether your bottle says metoprolol tartrate or metoprolol succinate.
These are the same drug, but they release differently. Tartrate releases all at once and wears off within a few hours. Succinate releases slowly over 24 hours. That difference changes when and how often you need to take it.
Most guides online lump them together or bury the distinction three paragraphs in. Here's the clear breakdown.
Metoprolol Tartrate vs Succinate: Timing at a Glance
| Metoprolol Tartrate | Metoprolol Succinate | |
|---|---|---|
| Brand name | Lopressor | Toprol-XL |
| Release type | Immediate-release | Extended-release |
| How often | Twice daily (sometimes 3x) | Once daily |
| Typical schedule | Morning + evening | Morning or evening (your choice) |
| Half-life | 3-7 hours | 3-7 hours, but extended-release design provides 24-hour coverage |
| Take with food? | Yes, with or right after a meal | With or without food (consistency matters more) |
| Can you crush/split it? | Yes | Can split at the score line, but never crush or chew |
If You Take Metoprolol Tartrate (Twice Daily)
With tartrate, you don't get to choose morning or night. You take it at both. The FDA prescribing information recommends evenly spaced doses, typically with breakfast and dinner.
Spacing matters because tartrate has a half-life of 3 to 7 hours. The drug level in your blood drops fast between doses. If you take both doses too close together (say, 8 AM and noon), you'll have hours in the evening and overnight with very little coverage.
Best practice for metoprolol tartrate timing:
- Take your first dose with breakfast (around 7-8 AM)
- Take your second dose with dinner (around 6-7 PM)
- Aim for roughly 10-12 hours between doses
- Always take it with food or right after eating to help absorption and reduce stomach discomfort
If you work non-standard hours, anchor doses to your meals rather than clock times. Consistent spacing matters more than specific hours.
If You Take Metoprolol Succinate (Once Daily)
With the extended-release version, you have more flexibility. You can take metoprolol succinate in the morning or at night. The FDA label says to take it "regularly and continuously, preferably with or immediately following meals," but doesn't specify morning or evening.
So how do you decide between metoprolol morning or evening dosing?
When morning works best
Morning dosing is a good default for most people. You can pair it with breakfast and your other morning medications. If you're managing multiple medications, grouping them at one time simplifies your routine.
Morning also makes sense if metoprolol doesn't cause you dizziness or fatigue. If you've been on it for a few weeks with no issues, keep doing what's working.
When evening or bedtime works best
The NHS notes that your doctor may advise taking your first dose at bedtime in case it makes you dizzy. Common side effects of metoprolol include tiredness, dizziness, and depression. If those hit you hardest in the first few hours after taking it, nighttime dosing lets you sleep through the peak.
Bedtime dosing can also help if:
- You feel sluggish or fatigued during the day when taking it in the morning
- Your doctor says your blood pressure doesn't drop enough at night (a pattern called "non-dipping")
- You already have an established evening medication routine
Don't switch times on your own
If you want to change the time you take metoprolol succinate, talk to your doctor first. They may want you to transition gradually rather than jumping from morning to night in one day, especially at higher doses.
Take Metoprolol With Food: Here's Why
Metoprolol tartrate should be taken with meals or right after eating. According to MedlinePlus, taking the regular tablet with food can reduce stomach-related side effects. For succinate, the FDA patient counseling information advises taking it "preferably with or immediately following meals," though food does not significantly affect how the drug is absorbed.
Pairing either form with the same meal each day helps you build a consistent routine. If you take other medications that have strict food rules, check our guide on when to take medication with food to build a schedule that works for everything.
Never Stop Metoprolol Suddenly
Do not stop taking metoprolol without your doctor's guidance. The FDA warns that abrupt discontinuation of beta-blockers can trigger serious problems, including worsened chest pain (angina) and in some cases, heart attack.
If you and your doctor decide to stop metoprolol, the standard approach is a gradual taper over 1 to 2 weeks. Read more in our full guide: What Happens If You Stop Taking Blood Pressure Medication.
What If You Miss a Dose of Metoprolol?
If you forget a dose, skip the missed dose and continue your regular schedule. Do not take a double dose to make up for it. If you're unsure what to do, call your pharmacist.
Because tartrate has a short half-life, missing a dose means your blood pressure and heart rate can rebound faster than with longer-acting medications. We cover exactly what to do (and what to watch for) in our detailed guide: Missed a Dose of Metoprolol? Here's What to Do.
The best way to avoid missed doses is a reminder system that won't let you forget. If you've ever wondered whether you already took your pill today, you're not alone.
How Pillo Helps You Stay on Schedule
Keeping track of twice-daily metoprolol tartrate or a once-daily succinate dose is easier with a reminder that actually gets your attention. Pillo's persistent alarm won't stop until you acknowledge it, so doses don't slip by during a busy morning or a drowsy evening.
You can set separate reminders for each dose, track whether you've taken them, and get refill alerts before you run out. If your phone rings mid-reminder, Pillo's smart snooze pauses the alarm and brings it back when you're off the call.
Frequently Asked Questions
Should I take metoprolol in the morning or at night?
It depends on your form. Metoprolol tartrate is taken twice daily, so you take it at both morning and evening meals. Metoprolol succinate (extended-release) is once daily. You can take it in the morning or at night. Choose whatever time fits your routine and helps you remember. If it causes dizziness, bedtime may work better.
Can I take metoprolol on an empty stomach?
You can, but taking it with food is recommended. The FDA prescribing information says to take metoprolol tartrate with or immediately after meals. Succinate is less strict, but pairing it with a meal helps build a consistent routine and may reduce stomach discomfort.
Is it OK to take metoprolol succinate at bedtime?
Yes. Taking metoprolol succinate at bedtime is fine as long as your doctor agrees. It can help if you experience side effects like tiredness or dizziness during the day, since you'll sleep through the peak effect. Take it at roughly the same time each night.
What happens if I take metoprolol too late in the day?
For succinate (once daily), taking it a few hours late is usually fine. Just take it when you remember and return to your regular schedule the next day. For tartrate (twice daily), a late dose could put your doses too close together. If your next dose is within a few hours, skip the late one instead of doubling up. Call your pharmacist if you're unsure.
Can I take metoprolol and lisinopril at the same time?
Many people take both together. Metoprolol and lisinopril work through different mechanisms to lower blood pressure, and doctors commonly prescribe them as a combination. Check with your pharmacist about your specific situation, and see our guide on the best time to take lisinopril for more timing tips.
