Hello, I ve read your queries and i understand your concern Thanks for writing to healthcare magic Cyp-L has cyproheptadine. It increases appetite by stimulating hypothalamic (part of brain) regions. And is a drug which is to be used with caution because of its side effects like dizziness, urinary retention, fever, dry mouth, loss of attention, etc. I would advice you to continue only for a short duration like 2 weeks. If there is no improvement in appetite, better stop it !! If your child is active do not worry. Try doing a master health check to look for micronutrient deficiencies and undiagnosed body problems. Give your child nutritious foods, vegetables and fruits. Do not dilute milk which is a common mistake mothers do. The medication is prescribed to increase your baby s weight Take Care
