Rebecca asked

Hi there. I was wondering if there any interactions between trazodone and Mucinex D (it has sudafed in it)?. I took trazodone last night for sleep at 11pm, and want to take Mucinex D now (2pm). I also want to be able to take my trazodone tonight at 10 pm. Let me know if this is ok


Drugs In MortarMucinex D and trazodone do not have any drug interactions and may be taken together safely. However, the pseudoephedrine in the Mucinex-D, which is a nasal decongestant, can cause you to have trouble sleeping if taken too close to bedtime, which can counter the effects of trazodone if you are taking it for insomnia.

Pseudoephedrine is a decongestant used to treat sinus congestion and pressure caused by the common cold or allergies. This medication provides temporary symptomatic relief by promoting nasal or sinus drainage.

Sudafed can be taken with or without food but if taking the extended release formulations, it is important not to crush or chew the tablets.
