Hello. Seacod tab is mainly used after 12 years of age despite this you can use syp. Uprise d3 for short time period for your child after consulting pediatrician. B29 syp can be given as dose of 5 ml once daily is sufficient after consulting pediatrician.
If your doctor has prescribed those medicines and you r under regular follow up. Then he would have done so with a very strong reason, I think you should have faith in your doctor's clinical judgement and go ahead with the treatment. Or perhaps have a good discussion with the doctor about the health of your child, i'm sure your doctor will be glad to resolve your worries.
If consistency of diarrhoea nit improved and child is not active then you should consult pediatrician. If child is playful, no weight loss then give zinc 14 days and continue probiotics woth diet management.
Constipation may be due to large number if reasons in children. Mainly depends on diet and habits of children. Feed him food with high dietary fiber like green leafy vegetables, fruits (not juices), beans, nuts etc. Considering the child is 10-12 kgs, I suggest you use duphalac solution 10 ml at every night after food. If this all fails he may need to be investigated further for evaluation. Dr. Sumanth marthyaya
