Allegra and Insomnia

Insomnia is not a common side effect of Allegra. Because of the infrequency of insomnia as a side effect, the connection between Allegra and insomnia is not completely clear. When insomnia does occur, it can often be improved by using good sleep habits, such as keeping a regular sleep-wake cycle and avoiding caffeine or large meals before bedtime.

An Overview of Allegra and Insomnia

Several side effects can occur with Allegra® (fexofenadine hydrochloride). Insomnia is an Allegra side effect that was reported in postmarketing experience. This means that even though studies did not indicate that insomnia was a possible side effect of Allegra, some healthcare providers have reported that they think Allegra may cause insomnia in some people. Because healthcare providers voluntarily report such side effects, it is impossible to tell exactly how frequently insomnia occurs with Allegra, although it is probably fairly rare.

What Is Insomnia?

People with insomnia have one or more of the following symptoms:
  • Difficulty falling asleep
  • Waking up often during the night and having trouble going back to sleep
  • Waking up too early in the morning
  • Unrefreshing sleep.

Allegra and Insomnia: Suggestions

Some people taking Allegra find that improving their sleep habits can be an effective insomnia cure. Some tips for better sleep include:
  • Keeping a regular sleep-wake cycle. Try going to bed and waking up at the same time every day.
  • Avoiding caffeine, alcohol, or nicotine in the four to six hours before bedtime.
  • Refraining from exercise within two hours of bedtime. (Exercising five or six hours before bedtime may help you sleep more soundly.)
  • Not eating large meals within two hours of bedtime.
  • Not taking naps later than 3 p.m.
  • Sleeping in a dark, quiet room at a comfortable temperature.
If you can't fall asleep within 20 minutes, do a quiet activity somewhere else and return to bed when you are sleepy.
Wind down in the 30 minutes before bedtime with a relaxing pre-sleep ritual, such as a warm bath, soft music, or reading.
