Sometimes when we go to the doctor for a sore throat or a skin infection, we are prescribed an antibiotic, right? One popular drug that is given like this is Erythromycin. Today we are talking about the chewable tablets of this drug. If you are using this drug, or if you are giving it to your child, it is very important to be aware of the facts we are talking about.
What is Erythromycin?
Simply put, erythromycin is an antibiotic. Its main function is to treat bacterial infections in our body. Sometimes you can find it under the brand name `EryPed`.
The most important thing to remember is that this medicine only works on bacteria. It will not cure viral illnesses like colds and flu.
Therefore, never do things like "I took an antibiotic I had at home as soon as I had a fever" without consulting a doctor.

It is important for your doctor to be fully informed about your health status before prescribing this medication. Be sure to tell your doctor if you have any of the following conditions:
| Your health condition | Why should you inform? |

| Liver disease | This medication can affect the liver, so it should be taken into account if you already have liver disease. |
| Myasthenia gravis | This is a muscle-weakening disease, and erythromycin can worsen symptoms. |

How exactly do you use this medicine?
Since this is a chewable tablet, special care must be taken in how it is used.
- Chew well: Before swallowing this pill, you should chew it thoroughly until it is completely crushed . Otherwise, do not swallow it whole.
- When to drink: For best results, it is best to drink on an empty stomach , either half an hour (30 minutes) before a meal or two hours after a meal.
- If you experience stomach upset: Some people may experience a slight stomach discomfort or heartburn when taking this on an empty stomach. If that happens, it's okay to take it with a little food or a glass of milk.
