i have lung cancer 4rth stage and i had been prescribed tylenol 3 RATIO-lenoltec NO.3 30 MG acetaminophen 300 mg / CAFEINE / Codeine PHOS 30 MG 2 TABLETS BY MOUTH EVERY 6 HOURS WHEN NEEDED. I am always in constant pain and the most side effect is constipation. so i was given SENNOSIDES 2 TABLETS 8.6 MG 2 TABLETSBY MOUTH AT NIGHT AND Dulcolax Bisacodyl tablets 5 mg , 10 g HS . but i have to see my doctor and i ave to leave very early with lots of blood works, ct scan and MRI SO I WOULD BE in the road for 2 hours before i reach the hospital. Can i take GLYCERINE SUPPOSITORIES 2.6 gm instead just for today so i can have my BOWEL movement before leave the house?
