How can I tell if a pill is Ambien (zolpidem)?
Ambien is the brand name for zolpidem, a prescription sedative-hypnotic. Because tablets can look similar across manufacturers and doses, the most reliable identification is not visual. Use the markings on the pill plus the prescription bottle label (drug name, strength in mg, and NDC/lot) to confirm.
If you only have the pill, look for these clues:
- Imprint/lettering on the tablet (the exact letters/numbers)
- Color
- Shape (round/oblong)
- Size (if you can measure with a ruler)
- Whether it’s immediate-release vs. extended-release
- Ambien typically refers to immediate-release zolpidem.
- There is also Ambien CR (extended-release), which may have different tablet markings.
Why “looks like Ambien” isn’t enough
Pills from different drugs can share similar colors and shapes, and zolpidem tablets at different strengths (and generics) may use different imprints. Without the exact imprint text, you can easily misidentify it—dangerous because zolpidem is sedating and can interact with other medications and alcohol.
What information do I need from the pill?
To identify it accurately, you’d need the pill’s:
1. Exact imprint (every letter/number as written)
2. Color
3. Shape
4. Any score line (and which side it’s on)
5. Immediate-release or extended-release (if you can tell from the imprint or packaging)
6. Where you are (country/state) can matter for manufacturer codes
If you share those details (especially the imprint), I can narrow it down.
What to do if you found the pill or aren’t sure it’s zolpidem
If you did not get it from a prescription you control, treat it as unknown until verified.
- Don’t take it “just to test.”
- Store it away from children and others.
- If someone may have taken it, contact Poison Control now (US: 1-800-222-1222) or local emergency services.
- In emergencies (trouble breathing, severe sleepiness, confusion, fainting), call emergency services.
How should Ambien be packaged?
Prescription bottles for zolpidem typically show:
- Drug name (Zolpidem or Ambien/Ambien CR)
- Strength (mg)
- Directions
- Pharmacy NDC (on the label)
If the bottle label doesn’t match the tablet imprint/strength, don’t use it and ask the pharmacist to verify.
Next step
Send the pill’s imprint text, color, and shape (and score line if present). If you have the prescription bottle label, include the strength (mg) and whether it says Ambien or Ambien CR.
