I have a cold. Is it safe to keep taking my probiotics and 5-HTP if I'm taking OTC meds for the cold?

Currently I'm only finishing up a tube of Airborne. I'll be taking my last Airborne tablet in a couple of hours. If I don't feel better I'm gonna start taking either Nyquil or Tylenol Cold Severe Head Congestion. Do you think it will be safe if I continue to take my probiotics (I take 2-3 Garden of Life Primal Defense Ultra probiotic capsules a day) and 1 capsule of 5-HTP 100mg while taking either one of the cold medicines I listed above? Does anyone know if it's ok to do this?
Answer:
They will not interfere with the cold medicine and the probiotics will help if you have a sensitive stomach.
