How you prepare

Tell your doctor if you've received any type of botulinum toxin injections within the past four months. And tell him or her if you take muscle relaxants, sleeping aids or allergy medications.

If you take blood thinners, you may need to forgo them for several days before your injection, to reduce your risk of bleeding or bruising.
