Are Dicyclomine Hydrochloride And Simethicone Right Medication For Stomach Pain In A Child?

My 5-1/2-year-old son is complaining of stomach pain from morning. No other accompanying symptoms (like fever or headache), just stomach pain. We gave dicyclomine hydrochloride and simethicone suspension. He has had 3 semi-liquid stools until now. Is it fine to continue the same medication along with oral hydration?
