Got these from an IOP. They look very legit I believe them to be, but just wanted to check and see what some experts have to say. Each pill has "CIBA" scored on one side and "AB" scored on the other with a break separating the two letters. The Registration Number on the back of the blister pack checks out as "Ritalin, 10mg." Here are some photos to help with the ID:

CIBA AB

I can't find a description of Ritalin from Mexico, but here are the descriptions of Ritalin marketed in Canada:

Ritalin® is available as tablets in strengths of 10 mg and 20 mg.

10 mg: Type: tablet. Appearance: pale blue, round, flat-faced, bevelled-edged. Markings: marked "AB" and scored on one side and marked "CIBA" on the other. Active ingredients: 10 mg of methylphenidate. Nonmedicinal ingredients: cornstarch, FD&C Green No. 3, lactose, magnesium stearate, polyethylene glycol, sugar, and talc.

20 mg: Type: tablet. Appearance: pale yellow, round, flat-faced, bevelled-edged tablet. Markings: marked "PN" and scored on one side and marked "CIBA" on the other. Active ingredients: 20 mg of methylphenidate. Nonmedicinal ingredients: D&C Yellow No. 10, lactose, magnesium stearate, polyethylene glycol, sugar, tragacanth, and talc.

Information from MediResource, Canada.

Since your tablet has the exact same imprint, it's a good bet it's genuine Ritalin.Laughing
