Shortness of breath, Mild swollen tongue

Hello, I have been put on the following medicines since yesterday, 1) Cernos 40 mg - soft gelatin capsules (1 - 1 - 1) - daily 2) tadalfil 20 mg (0 - 1 - 0) - alternate days Things were perfectly fine for about 3 hours after I consumed the above mentioned meds. I consumed the meds at around 3:45 pm & I was all OK till around 6:45 pm. However, post that I developed the following side effects, 1) shortness of breath 2) Mildy swollen tongue These effects lasted till around 9:45 pm .They started to disappear after that & right now I feel normal. I even consumed a cernos tablet after my dinner & it did not cause any issues. Are these side effects common.Is this the phase where my body is trying to adjust to the meds or is it a serious issue. I have been asked to be on these meds for 6 weeks. Could you please help me understand the long term side effects of both the meds prescribed. Should I stop consuming the meds & visit the doctor again?
