• Tramadol 50 mg capsules are usually green and yellow, while 50 mg tablets are commonly white or pale yellow depending on manufacturer.
• The imprint code on pill is most reliable way to confirm it is tramadol, with common imprints including 355 U, 93 58, AN 627, and MP 717.
• If your tramadol looks different from your last refill, it is likely a generic manufacturer switch, but always verify imprint to be sure.
The 50 mg capsule is most commonly prescribed immediate release form of tramadol. In its capsule formulation, it is typically a size 4 hard gelatin capsule with a green cap and yellow body, filled with white to off white powder.
Not all countries and manufacturers use capsule form. In U.S., tramadol 50 mg is more frequently dispensed as a tablet rather than a capsule. The tablets come in several appearances depending on who made them.
Here are some of most common tramadol 50 mg tablets you might encounter in the U.S.
• 355 U: Pale yellow, oblong, film coated tablet. Made by Unichem Pharmaceuticals.
• 93 58: White, oval tablet. Made by Teva Pharmaceuticals.
• AN 627: White, round tablet. Made by Amneal Pharmaceuticals.
• 101 OUYI: White, oblong tablet. Made by Jingxin Pharmaceutical.
• MP 717: White, round tablet. Made by Mutual Pharmaceutical.
All of these contain tramadol hydrochloride 50 mg and work the same way regardless of their colour or shape. You can verify any imprint through National Library of Medicine's drug label database: DailyMed tramadol hydrochloride label.
Tramadol is also available in extended-release formulations at higher strengths (100 mg, 200 mg, and 300 mg). These are designed to be taken once daily and are usually tablet or capsule shaped.
Extended-release tramadol tablets are typically white or off white and oblong. The 100 mg extended-release tablet, for example, is often white and round with imprint "L010." Higher doses tend to be larger in size but follow a similar white colour scheme.
It is important to never crush or split extended release tramadol. These tablets are designed to release the medication slowly over time. Breaking them can release full dose at once, which increases risk of serious side effects including respiratory depression.
Pharmacies switch between generic manufacturers regularly based on supply and pricing. When this happens, your refill may come in a different colour, shape, or size than what you had last time. A tablet that was white and round last month could be pale yellow and oblong this month.
This does not mean you received the wrong medication. The active ingredient, dose, and effect remain same across manufacturers. If you are ever unsure, check imprint code against a pill identifier or ask your pharmacist to confirm the switch.
If your pill has no imprint at all, do not take it. The FDA requires all prescription medications sold in U.S. to carry an imprint code. A pill without one may be a supplement, a foreign product, or something unregulated. This is especially important with tramadol because it is a Schedule IV controlled substance with a potential for misuse.
If you are taking tramadol for pain management and want to understand more about types of pain it is typically prescribed for, this article on dull pain meaning explains different ways pain presents and when medication may be needed. And for a broader look at how pill identification works across different medications, this guide on M 05 52 pill identifier walks through another common example.
Tramadol capsules are typically green and yellow at 50 mg strength. Tramadol tablets vary more widely in colour, with common versions appearing white, pale yellow, or off-white depending on manufacturer. The imprint code is always most dependable way to confirm what you have. If your tramadol looks different from a previous refill, your pharmacy likely switched generic suppliers. Always verify using imprint, and never take a pill that has no markings.
