Valium Side Effects

by on January 8, 2012


The most common side effects of Valium (diazepam) are minor and may include drowsiness, dizziness, and headaches. These side effects may go away on their own as the body adjusts to the medication. In cases where valium side effects are disruptive, a healthcare professional can help the patient develop a more effective treatment regimen. Serious valium side effects are rare and include changes in behavior, hallucinations and flu-like symptoms.

Valium side effects can be very serious for pregnant or breastfeeding women. In animal studies, valium caused birth defects. Valium (diazepam) belongs to pregnancy category D. This indicates that the medication is considered dangerous for pregnant women. If you are pregnant, breastfeeding or plan to become pregnant, you should consult your doctor about a possible alternative to valium (diazepam).


Valium side effects from abrupt withdrawal can be very uncomfortable and potentially dangerous. The patient's valium dosage should always be monitored by a health care professional. If you wish to stop taking valium, consult your doctor for a gradual withdrawal program which will cause fewer side effects.  Side effects associated with withdrawal include the following:

  • Depression
  • Insomnia
  • Confusion
  • Irritability
  • Hallucinations
  • Personality changes
  • Panic attacks
  • Dizziness
  • Nausea
  • Vomiting
  • Diarrhea
  • Fever
  • Headaches
  • Anxiety
  • Sweating
  • Numbness or tingling
  • Tachycardia
  • Memory loss
  • Tension
  • Heart palpitations

Withdrawal symptoms may also occur if a person becomes addicted to valium. If this happens, the patient should consult a doctor for assistance in quitting the medication and finding an alternative solution for their condition.

Valium is an effective treatment for many people, and most patients experience no serious side effects from the medication. If you do experience side effects, the best course of action is always to consult your healthcare provider. Stopping the drug on your own, even to eliminate side effects, can be unpleasant and dangerous. If and when you do decide to stop taking valium, use a gradual withdrawal method to minimize adverse side effects as much as possible.
