###Human: Is it normal to have nausea and stomach pain after taking Panadol? ###Assistant: Hello. The drugs that you mentioned all contain NSAIDs. These drugs are known to damage stomach mucosal lining and cause gastritis. I would suggest to minimise these drugs. You can use some over-the-counter antacids like Pantoprazole or Ranitidine available at stores along with syrup Gaviscon for a couple of days. If symptoms persist, you should get yourself examined by a gastroenterologist locally.
