Hi,

Your son is suffering from abdominal pain and two episodes of vomiting, which is usually due to difficult movement of bowel (pain occur off and on whenever gut moves).
Following infection of gut or indigestion due to contaminated food these symptoms can occur.

I advise you to do the following-

1. Feed him a liquid diet first like plain water, fresh juice which is not sour; if he tolerates that try soft bland food
2. Avoid milk and milk products
3. If he continues to vomit please take him to the paediatrician
5. Watch out for diarrhoea and fever
6, Give a Proton pump inhibitor (like omeprazole or lansoprazole granule)
7. You can add dicyclomine (an antispasmodic) which relaxes the gut muscle and will give some relief in his stomach pain.

8. Oral antibiotics can be started.

Now about meftal spas, it is an analgesic+antispasmodic drug. It can be used in stomach pain particularly in women having dysmenorrhoea. As it is an analgesic (NSAID) so it has lots of side effects like- gastritis, gastric erosion and gastric ulcer, Sleepiness, diarrhea, abdominal crunches, constipation, vomiting, gas, unusual heart burn etc. So it can only be used safely in stomach pain when a PPI (like omeprazole) or H2 antagonist (like ranitidine, famotidine etc.)
So please try to avoid meftal spas in your son as it may aggravate his stomach pain by causing gastritis/gastric erosion/gastric ulcer and also can cause vomiting as a side effect. Dicyclomine will reduce his stomach pain.

Your child should be done scanning of the abdomen, some routine blood investigations (like complete blood count) to diagnose the disease.

Consult your physician, tests to be done and advice to be followed based on his prescription.

Hope I have answered your query. If you have any further questions I will be happy to help.
