  • In the United States, some major drug plan insurers have implemented tablet-splitting programs that target statins.
  • Tablet splitting has been shown to reduce prescription costs substantially without negatively affecting laboratory outcomes or compliance
  • In addition, patients have found tablet splitting to be simple and acceptable


Supporting Evidence

  • A retrospective chart review of total cholesterol and LDL cholesterol values of patients instructed to split simvastatin or atorvastatin between January 1999 and November 2000
  • The overall results for this review demonstrated no statistically significant increase in total cholesterol and LDL cholesterol concentrations. Total cholesterol and LDL cholesterol values actually decreased from presplitting to postsplitting, p = 0.017 and p = 0.003, respectively.

Manufacturers Recommendations

  • No information provided on tablet splitting
  • Most drug companies oppose pill-splitting. They say it can be dangerous. But studies to date have not shown any adverse impact on health on the drugs listed safe to be split

Not To be Split

  • combination medications such as Liptruzet (atorvastatin/ezetimibe), Advicor (lovastatin/niacin) or Vytorin (simvastatin/ezetimibe)
  • time-release drugs, such as Altoprev (lovastatin sustained-release tablets), or Lescol XL (fluvastatin sustained-release tablets)

Ways to Split

  • don’t use a knife—studies show doing so can result in unequal halves. Instead, get a pill splitter device.
  • A good practice is to split your pills one at a time, and take the second half as your next dose
