does lantus insulin peak
More peaking usually indicates less than 24 hours of activity. If your Lantus or Levemir âwears outâ before the day is done, this can cause unexplained highs before or soon after the time when the next dose is given. It can also cause low readings during its peak activity. For instance, if Lantus is given only at bedtime, night lows may become more likely due to a peak in activity, while if one injection is given in the morning, high readings may occur before breakfast due to the lessening activity from the previous dose.
