Make sure your practitioner is very experienced at Botox injections and is a respected medical professional. A salon stylist, for example, is not an appropriate person to administer Botox, because he or she would not have emergency equipment or sufficient medical knowledge if something went wrong. Some disreputable people have reportedly administered injections that were over- or under-diluted with saline, as well as counterfeit solutions that didn't contain Botox at all.
Finding an experienced practitioner is particularly important if you’ve never had Botox treatments before as he or she will devise an optimal treatment plan to address your forehead wrinkles. Furthermore, with an experienced, board-certified plastic surgeon you’ll be far less likely to experience any side effects like pain, bruising around the injection site, droopy eyelids, or mistakenly be administered too much Botox, leaving your face looking frozen for the next several months.
I increase the dose at each treatment cycle to 195 units. This is based on experience with patients with cervical dystonia, in whom higher doses result in a longer duration of effect. In addition, I transition to the next onabotulinumtoxinA treatment at 12 weeks by using occipital and trigeminal nerve blocks at 10 weeks. Most insurance companies will not cover onabotulinumtoxinA treatments earlier than 12 weeks, but in rare cases, 10-week cycles have been approved.
Tell your doctor if you have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (tell your doctor exactly which product you received); have recently received an antibiotic by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; take aspirin-like products or blood thinners.
