For Dental Abscess "I took 250 mg of erythromycin for a tooth infection as I’m allergic to penicillin. Side effects were pretty bad on the first few days, couldn’t eat, couldn’t get out of bed, diarrhea, fast heart rate. But after my body got used to it, the pain went after a few days of taking it. Dental pain is the worst pain I’ve ever experienced. I still can’t see my dentist because of this pandemic!!!"

For Skin or Soft Tissue Infection "Had an insect bite that got really badly infected on my calf to the point where I could barely walk, it was that painful. I was on penicillin, but that did very little. After taking this, it cleared up almost immediately. Although it's making me feel quite nauseous, where all it takes is a biscuit to make me want to throw up, I'm also having headaches and my heartbeat keeps going fast, but it worked a treat on my bite."

For Strep Throat "Took this after I got too sick off of Clindamycin. Took one 500 mg pill, and it quickly went downhill. About one hour in, I felt nauseous and like someone sucker-punched me below the ribs. Five minutes later, I was sweating and noticed my heart was racing. I checked, and it was beating 136 BPM. I then had trouble breathing and was in the toilet with intense diarrhea. Heart rate and breathing got so bad I was taken to the ER. While waiting 2 hours, I finally returned to somewhat normal. But my gosh. What a horrible drug. AVOID"
