Detailed Information

Tadalafil tablets are manufactured as an unscored, intact dosage form and are practically insoluble in water and very slightly soluble in ethanol. Tadalafil tablets should not be split and entire dose should be taken.1

Splitting or crushing tadalafil tablets may result in a patient receiving more or less than the prescribed dose. Data are not available to support any alternative dosing options beyond specific dosing/administration according to the approved tadalafil label.

Food and Drug Administration Guidance on Tablet Splitting

The FDA advises against tablet splitting unless it is specified in the drug’s labeling. In addition, the American Medical Association and other medical organizations also advise against tablet splitting.2 

If a tablet is approved by the FDA to be split, this information will be printed in the “HOW SUPPLIED” section of the professional label insert and in the patient package insert. In addition, the tablet will be scored with a mark indicating where to split it.2,3

If labeling does not include such information, the FDA has not evaluated the tablet to ensure that, if split, the 2 halves are the same in weight or drug content or work the same way in the body as the whole tablet.3
