Pm1 yellow pill?

I can’t reliably identify a pill from just “PM1 yellow” text. Imprints can match many different medicines across brands and countries. If you can share more details, I can help narrow it down.

What I need:
- Exact imprint as it appears (PM1, PM-1, Pm1, etc.)
- Shape and size (round, oval, capsule) and approximate measurements
- Any other marks or logos on either side
- Country where the pill was obtained (US, UK, etc.)
- A photo (if you can upload one)

If you need quick safety guidance in the meantime:
- Do not take a pill you’re unsure about.
- Keep the pill away from children.
- If there’s been any ingestion or you’re worried about exposure, contact your local poison control or emergency services.
- In the US, you can call Poison Help at 1-800-222-1222 for confidential guidance.

Once you share more details or a photo, I’ll help identify the pill or point you to reputable pill-identification resources.
