Reviews
On the Internet, patient opinions about Bellasthesin are mostly positive. It copes well with stomach pain due to gastritis with high acidity. The low price and rapid onset of effect are emphasized as advantages. The downside is that it cannot be used for a long time.
Gastroenterologists often prescribe tablets as part of complex therapy, but warn about short-term use. The disadvantages include the need to study the interaction of the drug with other medications if they are taken by patients.
