Visyneral Oral Drops provide essential vitamins for infants who may need nutritional support. The duration of use depends on the baby’s individual dietary needs and must be guided by your paediatrician. Multivitamins for infants are often prescribed daily for a few weeks to several months, but the exact length should be determined by the doctor based on the baby’s growth, diet, and overall health. Do not continue for an extended period without medical supervision.
