Equivalent pills — same medicine, different imprint
The pills below contain the same active ingredient at the same strength (Allopurinol 100 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.
