Safe Use of Transdermal Medication Delivery Systems

Introduction to Transdermal Medication Delivery Systems

Transdermal medication delivery systems, such as Dotti patches, can cause contact dermatitis, including both irritant and allergic contact dermatitis, with repeated applications to the same area, as reported by the British Journal of Dermatology 1

Using multiple patches simultaneously can lead to excessive hormone absorption, increasing the risk of adverse effects, including severe nausea and vomiting, renal failure, and metabolic disturbances, as documented in case reports 1
Excessive hormone absorption from multiple patches can also increase the risk of thromboembolic complications, including deep vein thrombosis and pulmonary embolism 1

To prevent accidental overdosing and minimize side effects, only one patch should be applied at a time, and patients should follow the prescribed schedule, typically one patch every 3-4 days 1
Rotating application sites is recommended to reduce skin irritation, as suggested by dermatology guidelines 1
Old patches should be removed before applying new ones to prevent accidental overdosing and minimize side effects 1

Patients should be monitored for severe or persistent skin reactions, signs of excessive estrogen, visual disturbances, severe abdominal pain, and jaundice, and report any concerns to their healthcare provider, as recommended by general medical guidelines 1
Patients should be aware of the risks associated with incorrect use of transdermal medication delivery systems, including fatal outcomes from multiple patch application due to severe vomiting leading to dehydration and renal failure, as documented in case reports 1
Common adverse effects of transdermal patches include:
In adolescents, the adverse effects of transdermal patches are similar to those in adults, but there may be greater concern about adherence and menstrual changes 2

Historia previa de reacciones alérgicas graves to components of the patch or medical conditions that contraindicate the use of specific hormones are contraindications for the use of transdermal patches 1
Reacciones cutáneas graves that do not improve with standard management require medical evaluation 1
Síntomas sistémicos severos or persistentes should be evaluated by a healthcare professional 1
