Because of the potential for serious adverse reactions in nursing infants from mecamylamine, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Long-term studies in animals have not been performed to evaluate the effects upon fertility, mutagenic or carcinogenic potential of mecamylamine.
