BACKGROUND AND OBJECTIVES: Non-obstetric causes of pain during pregnancy are very common and can be disabling if not treated properly. The objective of this study is to discuss the pharmacological treatment of pain during pregnancy with a focus on drug classification and pregnancy use, therapy options, teratogenicity, increased fetal malformations and gestational complications associated with the use of therapy. 

CONTENTS: During pregnancy, the body goes through several anatomical and physiological changes. These changes can precipitate pain, which in some cases can lead to disability. In addition, pregnancy may exacerbate pre-existing painful conditions. The choice to prescribe a drug to a pregnant woman is difficult. The changes in the body of a pregnant woman influence drug absorption, distribution, metabolism, and excretion, and may alter the expected response.

CONCLUSION: The risks and benefits of the drug for the mother and the child should be considered, weighing the risks of not treating the disease adequately during pregnancy.

JUSTIFICATIVA E OBJETIVOS: As causas não obstétricas de dor durante a gravidez são muito comuns e podem ser incapacitantes se não forem tratadas adequadamente. O objetivo deste estudo foi discutir o tratamento farmacológico da dor durante o período gestacional com foco na classificação de fármacos e o uso na gravidez, opções de terapia, teratogenicidade, aumento de malformações fetais e complicações gestacionais associados ao uso da terapia.

CONTEÚDO: Durante a gravidez, várias alterações anatômicas e fisiológicas ocorrem no corpo. Essas alterações podem precipitar a dor, que em alguns casos pode levar à incapacidade. Além disso, a gravidez pode exacerbar condições dolorosas pré-existentes. A escolha de prescrever um fármaco para uma gestante é difícil. As alterações gravídicas no corpo da gestante influem na absorção, distribuição, metabolismo e excreção dos fármacos, podendo alterar a resposta esperada.

CONCLUSÃO: Deve-se considerar os riscos e benefícios do uso do fármaco para a mãe e filho, pesando-se os riscos de não tratar adequadamente a doença durante a gestação.
