It is not used for treating a minor fungal infection such as a yeast infection of the mouth, esophagus, or vagina. The drug is currently in a short supply and the Centre is taking adequate steps to ramp up its production and its availability to states where there is high demand for the drug.
Mucormycosis of black fungus primarily affects people recovering from COVID-19 and has been steadily rising across the country. Several states, including Telangana, Odisha, Karnataka, Tamil Nadu, Rajasthan, Gujarat, and Haryana, have already declared black fungus an epidemic.
The treatment of this fungal infection requires a multidisciplinary approach consisting of eye surgeons, ENT specialists, general surgeons, neurosurgeons, and dental maxillo-facial surgeons, among others, and institution of Amphotericin-B injection as an antifungal medicine.

This rare drug is used to treat a variety of serious, fatal fungal infections. It helps in stopping the growth of fungi.

This drug is normally injected into the vein. Usually, a single dose of the drug is given to a patient daily, depending on his medical condition or as directed by his doctor. The injection is administered very slowly - over 2 to 5 hours. The dosage depends on a patient’s medical condition, weight, response to the test dose, and the therapy.
In some cases, the drug is given to a patient for several days, weeks to several months in order to treat certain infections.

Fever, shivering, loss of appetite, dizziness, nausea, vomiting, headache, shortness of breath, or fast breathing are some of the common side effects of this drug.

What is the Centre doing to scale up its production?
The Drug Controller General of India (DCGI) has recently granted approval to five pharma companies to start manufacturing antifungal anti-fungal drug Amphotericin B liposomal injection.
The five companies that got DCGI's nod are - Alembic Pharmaceuticals, Emcure Pharmaceuticals, Gufic Biosciences, Lyca Pharmaceuticals, and Natco Pharma. Presently six firms - BDR Pharma, Bharat Serums and Vaccines, Mylan, Sun Pharma, Cipla, and Life Care - are producing the drug.
"The existing pharma companies have already started ramping up the production. Indian Companies has also placed orders for importing 6 lakh vials of AmphotericinB," Minister of State for Chemicals and Fertilisers Mansukh Mandaviya said.
The government is also actively exploring other global sources from where the Amphotericin-B drug can be imported, and the Union Health Ministry is also trying to procure other anti-fungal drugs that can be used in the treatment of Black Fungus.
It is believed that nearly 7,000 people have been infected in India with the black fungus and over 200 have lost their lives. Maharashtra has reported the highest number of black fungus cases. Excessive use of steroids during COVID treatment and those with diabetes are more prone to catching the black fungus infection.
