Klonopin Pill Identification Overview

Klonopin (clonazepam) is a prescription medication belonging to the benzodiazepine (BZD) drug class.

BZDs are one of the most widely prescribed drug classes in the U.S. and are known for their calming effects on the central nervous system (CNS). They work by enhancing the effects of a natural brain chemical called GABA, leading to relaxation and reduced anxiety.

Considering Clonazepam is among the most addictive drugs on the market, it is important to identify the pill you were prescribed by your healthcare provider. Here is the breakdown of the key points for correct Klonopin pill identification:

Brand Name Klonopin Pill Colors and Shapes

Klonopin is exclusively manufactured by Roche Laboratories, which uses blue, orange, and white colors to indicate the medication’s strength.

Roche also marks the tablets with a distinctive K-shaped cutout, the dosage, and the company’s name. The color coding is:

  • 0.5 mg Klonopin pill: Orange, round and scored.
  • 1 mg Klonopin pill: Blue, round, and scored.
  • 2 mg Klonopin pill: White, round and scored.

Roche also offers a disintegrating tablet option for those who have difficulty swallowing tablets, which is white and has the dosage imprinted on one side. All Roche Klonopin pills have “K ROCHE” imprinted.

Roche Klonopin Pill Identifier

Color Imprint Image Dosage
Orange K-shaped perforation in the tablet with an imprint of 1/2 and ROCHE. Orange Roche Klonopin pill. 0.5mg
Blue K-shaped perforation with an imprint of 1 at the top and ROCHE on the bottom. Blue roche Klonopin pill. 1mg
White There is a K-shaped perforation in the tablet with an imprint of 2 at the top and ROCHE on one side of the bottom of the pill. White roche klonopin pill. 2mg
White This “wafer” is an orally disintegrating tablet with strength imprinted on one side, indicated by fractions (e.g., 0.5mg is marked as 1/2). Klonopin branded wafer. 0.125mg=1/8





Klonopin Generic Pill Identifier: Clonazepam Colors

Clonazepam was approved as a generic drug in the late 1990s, and now multiple pharmaceutical companies manufacture it in a variety of Klonopin pill colors, such as the Teva 833 or the blue pill marked c1.

These imprints help identify the manufacturer and the strength of the medication. Typically, insurance providers, including Medicaid and Medicare, cover only the generic versions unless a medical provider can validate the need for the brand-name medication. This often means trying the generic versions before moving to the more expensive brand-name option.

Take into account that symptoms of clonazepam overdose mirror those of other CNS depressants and can include drowsiness, confusion, coma, and reduced reflexes. Call 911 if you suspect someone is suffering a Klonopin overdose.
