Family Support

“The presence of severe and persistent side effects caused by the treatment of an aesthetic problem raises great concern for the clinician. A low estimated prevalence of PFS cannot be an excuse for nonvigilance since the drug is used by millions of relatively young and healthy individuals.”

“It is paramount that clinicians do their due diligence and not fall for the slogan ‘these drugs are well tolerated and safe.’’
