Is Oxyelite Pro Safe To Take While Having Cold?

I would like to know if I can take oxyelite pro when I have a cold? i work out regularly and eat very healthy (I am a dietitian). I think I have been stressing my body out working out while sick have had this cold for about 2 weeks (I work in several convalescent homes). But have been trying to lose a few extra pounds by using oxyelite pro, but have to take a break from the exercise so I can finally get better. Want to know if I can still take oxyelite if I am not going to really push myself with the cardio and P90x for a few days to a week.
