Dicyclomine injection is labeled for intramuscular use only. IV administration, including giving it diluted in an IV infusion, can cause thrombosis/thrombophlebitis and severe injection-site injury. Its labeled injectable dosing is for adults, and pediatric safety/effectiveness have not been established. DailyMed prescribing information

Paracetamol (PCM) IV may be used in children when clinically indicated, but it should be given using the specific pediatric product, dose, dilution, and infusion instructions, generally as a separate administration. Do not mix it with dicyclomine in the same bag without a pharmacist-approved compatibility protocol.

For a 10-year-old with abdominal pain/cramps, assess first for red flags such as persistent vomiting, localized right-lower abdominal pain, guarding/rigidity, bilious vomiting, blood in stool, dehydration, fever/toxic appearance, or altered consciousness. Those need urgent pediatric evaluation rather than empiric antispasmodic infusion.
