Get emergency medical help if you have signs of an allergic reaction to Sympazan (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
Sympazan can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing. A person caring for you should seek emergency medical attention if you have weak or shallow breathing, if you are hard to wake up, or if you stop breathing.
Call your doctor at once if you have:
severe drowsiness, feeling like you might pass out;
unusual changes in mood or behavior;
aggression, thoughts of hurting yourself; or
problems with balance or muscle movement.
The sedative effects of clobazam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking Sympazan.
Common Sympazan side effects may include:
constipation;
drowsiness, lack of energy;
fever; or
drooling.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
