Targeted mutation-based therapy with BRAF and MEK inhibitors has become an integral part of systemic therapy for metastatic melanoma in the advanced setting and for the adjuvant therapy of melanoma in stage III after complete resection. Due to the increased chances of survival and early use in the adjuvant situation, fertility preservation as well as aspects of teratogenicity and pregnancy are increasingly relevant in patients who are often still young. To communicate the published and study-based information on fertility preservation, teratogenicity and pregnancy under therapy with BRAF and MEK inhibitors. Summaries of product characteristics as well as studies and case reports on BRAF and MEK inhibitors published in PubMed were used as sources of information. There are no specific preclinical studies or experience in humans on fertility, teratogenicity, and contraception with targeted therapy. Recommendations can only be derived from toxicity studies and individual case reports. Patients should be offered counseling on the options for fertility-protective measures before starting targeted therapy. Due to unclear teratogenicity, adjuvant melanoma therapy with dabrafenib and trametinib should not be initiated in pregnant patients. In the advanced metastatic situation, BRAF and MEK inhibitors should only be given after extensive interdisciplinary education and counselling of the pregnant patient and her partner. Patients should be informed about the need for adequate contraception during targeted therapy. © 2023.
