Hello I just visited the doctor an he prescribed me four different medicines the first one is amox-clav 500mg twice a day for 10 days , prednisone 20mg once a day for 7 days , bromfed dm syrup 5ml every 4hrs and he also prescribed me 2 one time tablets of fluconazole 150 mg . First question is it safe to take all these meds at once without it affecting another?? And do these meds affect birth control??

Thank you in advance, hope someone can help me
