Talk to your doctor before using rimabotulinumtoxinB together with abobotulinumtoxinA.

In rare cases, swallowing and breathing difficulties may be life-threatening, so you should seek immediate medical attention if they occur. These medications should only be given by your healthcare provider and under direct medical supervision.
