It is possible to take amoxicillin if you have stomach problems. Amoxicillin belongs to the class of antibiotics, which has a broad-spectrum anti-inflammatory effect and has a therapeutic effect on various diseases. There are many people who have stomach diseases due to factors such as gastritis and gastric ulcers, and can use amoxicillin appropriately for anti-inflammatory treatment. However, when taking amoxicillin, you should try to take it half an hour after a meal to reduce the damage caused by the drug to the gastric mucosa. Some people develop stomach diseases caused by H. pylori infection, and amoxicillin can kill H. pylori in the stomach and play a role in curing the disease. However, since H. pylori is drug-resistant, it is best to use the treatment together with other antibiotics. The use of amoxicillin in combination with other medications, such as those that inhibit gastric acid secretion and protect the gastric mucosa, can increase the effectiveness of the medication while avoiding damage to the gastric mucosa.
