Iona Macca, I know that the paracetamol and codeine is safe, the only issue may be with the muscle relaxant that is in the mersyndol as well.

Probably best to check with the pharmacy or do some searching online for the particulare drug name - doxylamine succinate - in this case.

Usually medications state on the packet if they are not safe during pregnancy (check out an ibuprofen packet) and the fact that there is no warnings in this case tends to leave me feeling that it is safe.

I get shocking tension headaches at times, if they get bad the only thing that will do anything is mersyndol... Now that we are ttc I avoid it unless absolutely completely necessary, but have been forced to take it at times.
