No, Loperamide is not banned in India. It is among the most commonly used medicines in the country for the treatment of diarrhea. That’s why you can easily buy it in any corner of India from any local chemist's shop.
Not a lot of people know this, but this Loperamide medicine/drug is the one that is mainly and widely used to treat diarrhea, and it is a popular option in India too. It works pretty simply, actually, like, by limiting the activity of your gut, loperamide makes your stools to be of more solid in consistency and also lessens the frequency of your bowel movements. Plain and simple!
Loperamide is still a drug from the opioid family; however, it is not a drug of abuse and doesn’t affect the brain or produce any kind of high if used properly. That's the thing to keep in mind! Physicians generally prescribe it to adult patients where acute diarrhea is present and fast alleviation is necessary. Therefore, it is a somewhat obvious remedy that serves its purpose effectively.
For those who know little to nothing about it all, the Central Drugs Standard Control Organization (CDSCO) is the top decision-making body in India for drug manufacturing those which are allowed to be sold or used. It is an agency that operates under the Drugs & Cosmetics Act, which is a regulation that specifies the rules for the entire country regarding medicine. Just know that for now!
And yes, we must say that every state drug controller in the respective state is responsible for overseeing the implementation of the drug regulations at the local level, which means that they also ensure that drugs are in compliance with the guidelines issued by the National authorities. Consequently, even if the Central Drugs Standard Control Organization (CDSCO) imposes a ban on a medicine, it is the state authorities who verify that the products are not on the shelves of the stores.
