I have been told by many who have had pethadine that they didnt like it, I am due in the next 2wks and dont want an epidural and want to use gas & air but want to keep the option of pethadine open if i get into a panic and feel I cant cope, I was thinking of asking for a first dose of only 25mg so that if i dont like it i havent had to much, I understand that the normal hospital dosage is 150mg.......anyone able to comment?
