What happens when you eat some strong medicine,say antibiotic tablet empty stomach?

Unless the pharmacist has instructed otherwise, take the antibiotic with food or a glass of milk. Some antibiotics can cause stomach upset if taken on an empty stomach.

You may want to eat something smal if you don't feel like eating. Even if it's a piece of bread. I have taken an antibiotic by it self and was fine the first time but the next one I had to take I still hadn't eaten and good really sick to my stomach making me throw up
