The launch of the drug came at a time when the deadly virus has claimed 257 lives and affected 8,153 people in the country.
The drug is sold under the trade name Tamiflu and is taken orally in capsules or a drink.
The ministry of health and family welfare issued a notification on Tuesday allowing “restricted sale” of tamiflu (Oselatamivir) the only available drugs that are used for the treatment of Swine Flu.
Taking into account the current spread of the Influenza A(H1N1) in the country, the health ministry decided that retail sale of tamiflu should be allowed in the country but in a regulated manner.
The retail sale of tamiflu was banned by the central government and its distribution was permissible only through public health institutions.
A 10-tablet strip of tamiflu costs Rs.280.
