According to its FDA-approved label, Clonazepam is described as follows (reference information only — not advice about whether it is right for anyone):

In patients with absence seizures (petit mal) who have failed to respond to succinimides, clonazepam tablets may be useful....
Equivalent pills — same medicine, different imprint
The pills below contain the same active ingredient at the same strength (Clonazepam 0.5 mg). Different makers stamp their own codes, so equivalent pills often look completely different. This is factual label information — it is not a suggestion to substitute one product for another; only a pharmacist or prescriber can advise on that.
