If you experience nausea and vomiting after taking medication, you can give anti-emetic medication such as gastrofacial tablets to relieve the nausea and vomiting symptoms. Most of the nausea and vomiting after taking medication is caused by the side effects of the medication, which stimulate the mucous membrane of the gastrointestinal tract. In addition, if the nausea and vomiting sensation is obvious, consider whether to reduce or suspend the dosage of the medication and increase the interval of the medication to relieve the nausea and vomiting symptoms. If nausea and vomiting occur after taking the medication, if it is particularly severe, the medication should be stopped immediately and medication to protect the gastric mucosa, such as omeprazole or ranitidine, should be given for treatment.
