What Flexeril tablets look like

Flexeril (the brand name for cyclobenzaprine) comes in two standard tablet sizes, and the appearance depends on the dose. The 5 mg tablet is a white or off-white round tablet with "MSD 105" printed on one side and a score line on the other. The 10 mg tablet is a yellow or pale yellow round tablet marked "MSD 265" on one side, also with a score line on the reverse.

The score line on both tablets allows you to split the dose if your doctor prescribes it that way. If your tablet looks significantly different—a different color, shape, or marking—double-check the label on your bottle or contact your pharmacy, because you may have received a generic version or a different medication.

Generic cyclobenzaprine tablets vary widely in appearance depending on the manufacturer. Some are round, some are oval, and colors range from white to yellow to other shades. The imprint will always include the manufacturer's code and the dose strength, so reading the imprint is the most reliable way to confirm what you have.

Key Takeaways

  • Brand-name Flexeril 5 mg is a white round tablet marked "MSD 105" with a score line on the back.
  • Brand-name Flexeril 10 mg is a yellow round tablet marked "MSD 265" with a score line on the back.
  • Generic cyclobenzaprine tablets look different depending on the manufacturer but always carry an imprint showing the dose and maker's code.
  • The score line allows the tablet to be split in half if your doctor directs you to do so.
  • If your tablet's appearance does not match your prescription label, contact your pharmacy before taking it.

Why tablet appearance matters

Knowing what your medication looks like is a basic safety step. If you take multiple tablets, you need to be able to tell them apart at a glance. If a tablet looks wrong—chipped, discolored, or marked differently than usual—you can catch a dispensing error before you take it.

Appearance also helps you remember whether you have already taken your dose. Many people keep their tablets in a weekly organizer or pill box, and a quick visual check confirms you are taking the right medication at the right time.

Generic versions and how they differ

When your pharmacy fills a prescription for Flexeril, they may dispense the brand-name tablet or a generic equivalent, depending on what your insurance covers and what the pharmacy stocks. Both contain the same active ingredient (cyclobenzaprine) at the same dose, but they look different because different manufacturers make them.

Common generic imprints include "M" with a number, "MYLAN" codes, "TEVA" codes, and others. The imprint always includes enough information for you or a pharmacist to identify the drug and dose. If you are unsure what a generic tablet is, the pharmacy label on your bottle will tell you the drug name, dose, and manufacturer.

What to do if your tablet looks wrong

If a tablet is chipped, cracked, or discolored, or if the imprint is unclear or missing, do not take it. Set it aside and contact your pharmacy. A damaged tablet may not deliver the correct dose, or the damage could indicate a storage or handling problem.

If the tablet looks completely different from what you expected—a different shape or color than your last refill—call your pharmacy before taking it. Dispensing errors are rare, but they happen. A quick phone call takes two minutes and rules out a mistake.

If you have questions about whether a tablet is safe to take, your pharmacist can answer them over the phone and can often look up the imprint in their system to confirm what you have.

Storing your tablets safely

Keep Flexeril in its original bottle with the label intact. The label tells you the dose, the number of tablets, the expiration date, and the pharmacy contact information. If you transfer tablets to a pill organizer or other container, write the dose and expiration date on the new container so you know what you are taking and when it expires.

Store tablets at room temperature, away from moisture and direct sunlight. Do not store them in a bathroom medicine cabinet, where humidity can damage them. A cool, dry closet or drawer works better. Damaged or discolored tablets should be discarded according to your pharmacy's instructions—many pharmacies accept old medications for safe disposal.

Frequently Asked Questions

Can I split a Flexeril tablet in half?

Only if your doctor tells you to. The score line on both the 5 mg and 10 mg tablets allows them to be split, but splitting should only happen on your doctor's instruction. Never split a tablet on your own to change your dose.

What if I get a generic that looks completely different from my last refill?

Different manufacturers make generic cyclobenzaprine, so appearance can change from one refill to the next. Check the imprint and the pharmacy label to confirm the dose and drug name. If the label says cyclobenzaprine and the dose matches your prescription, the tablet is correct even if it looks different.

Is it safe to take a tablet that is slightly discolored?

Minor color variation between tablets from the same batch is normal. If one tablet is noticeably darker, lighter, or stained compared to others in the same bottle, set it aside and ask your pharmacist. Significant discoloration can indicate moisture damage or a manufacturing defect.

How long do Flexeril tablets stay good?

Flexeril tablets are stable for the expiration date printed on your bottle, usually one to three years from the fill date. After the expiration date, the medication may lose potency or break down. Do not use tablets past their expiration date.
