Patient's question:
Today, my stomachache was very severe. Accompanied by my mom, I went to the hospital and received two injections. Finally, it improved a lot. On the way back, the doctor prescribed some medicine for me, which includes a drug called Cimetidine. I asked an expert: What is the package insert for Cimetidine? What are its side effects?Doctor's answer:
Cimetidine's function is to significantly inhibit gastric acid secretion induced by stimuli such as food, histamine, or pentagastrin, thereby reducing its acidity. It also has a preventive and protective effect against corrosive gastritis caused by chemical irritation. It is commonly used for symptoms such as duodenal ulcers, gastric ulcers, gastroesophageal reflux disease, and upper respiratory tract bleeding.Note:
- Gastrointestinal reactions: Common side effects include diarrhea, bloating, bitter taste in the mouth, dry mouth, and mild elevated transaminase levels. Severe cases may involve hepatitis, liver necrosis, or fatty liver changes.
- Urinary system reactions: In recent years, there have been reports of this medication causing acute interstitial nephritis and leading to kidney failure. However, this toxic reaction is reversible, and renal function generally returns to normal after discontinuation.
- To avoid nephrotoxicity, renal function should be monitored during treatment, and it is best to take this medication under the guidance of a doctor.
