E-Mycin is a well-known brand name for Erythromycin, a macrolide antibiotic used for a great many bacteria-induced infections in the human body.
You need to take E-Mycin following your physician's guidelines precisely. Do not increase the dosage or the term of treatment on your own free will. E-Mycin can be ingested on an empty stomach freely, but if your body's usual reaction to antibiotics is diarrhea or upset stomach, you can take it with warm food or milk. If you are using enteric-coated or delayed-release pills, do not crush, break or chew them before swallowing. The former is specifically coated with a concoction meant to protect your stomach walls whereas the latter is designed to released a big amoung of the drug slowly and if your body receives the whole dose at once, trouble may ensue. The chewable E-Mycin tablets, on the contrary, need to be chewed thoroughly. The E-Mycin oral suspension must be shaken and measured with a special marked medicine cup or spoon. Usually this device goes with the E-Mycin pack, or it can be bought individually from any local pharmacist.
The most common E-Mycin side effects include mild nausea, diarrhea, stomach pain, vomiting; dizziness, headache, exhaustion; vaginal itching/discharge, mild itching or skin rash. If any of these symptoms increase to the point where they start bothering you too much, contact your doctor.
