V Mayilvaganan | TNN Thanjavur: An anti-retroviral therapy (ART) centre at the Thanjavur medical college has given expired drugs to at least 60 people living with HIV/AIDS. While experts say it isn't dangerous to take such drugs after the expiry date, some HIV positive people have complained of itching, vomiting and giddiness. The ART centre has been treating about 1,200 people with HIV/ AIDS. The 60 patients who received the expired drugs are from Thanjavur, Tiruvarur and Nagapattinam. Raman (46), one of the HIV positive people, said he developed itching, vomiting and giddiness last week.
