Can i take methadone and phenylephrine together i take 150mg of the metha.my nose is so stuffed i can hardly breath is this safe to take if not what is?

Talk with doctor: Although I see no problem with the mixture, I also double that phenylephrine would provide you enough relief. Is the congestion only present after you have taken metha or has it been present all along only to be aggravated by the metha? If the latter, you need to find out the cause such as allergies etc to keep the nose open .
