Hi I am taking an antibiotic clindamycin, I am having dental work done, he put me on this to clear up infection or get me ready to pop that crown on this tuesday, I had a root canal done. i am having a lot of heart burn with it or upset tummy feeling like I should take rolaids. I am 54 I have a life time of taking meds this one is making me burp......? all day I have taken it with food after food before food...tried it. Different kinds of food so any way I hate it, but today I noticed my face is red not like hives not like when i had my pennicilliin reaction but hot like flush with fever feels like i drank a bottle of wine my face looks like I have too much blush on I have none. This has been going on for 2 days. Should i stop for now taking these pills that warn me to take them all ?
