Travelers often overlook the importance of customs regulations regarding medications. Dr. Sundar Krishnan, a senior consultant at KIMS Hospitals in Thane, highlights that many common medications available in India may be restricted or banned abroad. Carrying large quantities or unlabelled medications can raise red flags at customs, leading to potential issues. To ensure a smooth travel experience, it's advisable to keep medications in their original packaging and have a doctor’s prescription that includes the patient's name, diagnosis, and dosage. Additionally, travelers should check the regulations of their destination country, as many allow only a 30-day supply of certain medications and require documentation. Proper planning and documentation can help avoid unnecessary complications at immigration counters and ensure uninterrupted treatment during travel.
