special instructions
Cancellation or replacement of Hexamidine with another drug is carried out gradually, since drug dependence may develop with prolonged treatment.
If megaloblastic anemia occurs, Hexamidine should be discontinued and vitamin B 12 and / or folic acid should be taken.
With prolonged therapy with anticonvulsants, it may be necessary to prescribe an additional amount of vitamin D, which is necessary to prevent osteomalacia.
There is evidence of a possible relationship between the use of anticonvulsants and an increased incidence of congenital malformations.
