No, it is not safe to take Miofree A while breastfeeding. Miofree A is a combination of Aceclofenac (a pain reliever) and Thiocolchicoside (a muscle relaxant). Thiocolchicoside is strictly contraindicated during breastfeeding because it can pass into breast milk and potentially cause harmful effects to your baby. Additionally, there is limited safety data regarding Aceclofenac during lactation. Taking this medication could pose risks to your nursing infant. Please consult your healthcare provider or pediatrician immediately so they can prescribe a safer alternative for pain and muscle spasms that is compatible with breastfeeding.
