The color of my insulin is it good?

  • Anonymous ORIGINAL POSTER
    The color of my novolog insulin is cloudy. Is this insulin good? can I still use it?
  • Samuel Grossman, BS Pharm, Pharm.D, CDE PROFESSIONAL
    The usual color of novolog is clear. Novolog solution can become cloudy if it is used passed it's expiration date or if it is exposed to extreme heat or cold. I would not advise for you to use the novolog insulin if it is cloudy.
