Effervescent tablets taken directly need to be remedied by drinking plenty of water. Effervescent tablets are a kind of tablets containing disintegrating agents that are highly soluble in water. The disintegrants contained in effervescent tablets are bicarbonate and organic acids, which produce carbon dioxide in large quantities in contact with water, leading to asphyxiation if taken directly. In addition, the effervescent tablets directly eaten will bring great stimulation to the mucous membrane of the gastrointestinal tract, which will make the patient appear nausea, vomiting, diarrhea and other symptoms. So effervescent tablets taken directly can be remedied by drinking a lot of water to accelerate the absorption of the drug and the disintegration of the effervescent tablets, to avoid the effervescent tablets stuck in the throat, or the release of carbon dioxide catalyzed by salivary amylase, resulting in choking. If the symptoms are not relieved after taking effervescent tablets directly, or when accompanied by other symptoms, you should go to the hospital in time to see a doctor to clarify the cause and then give targeted treatment.
