They don't produce EpiPen's as a generic in India because the Indian medical community does not recommend self-administration of epinephrine.
If you're that much in need though, you can buy pre-filled epinephrine syringes for intramuscular injection - just keep in mind the ease-of-use of an EpiPen won't be available. You have to take the time to take off the cap, insert and inject the medicine.
I assume they intramuscularly inject epinephrine just as you would with an EpiPen. I doubt it'd be hard for patients to get hold of an epinephrine kit.
You'll also find developing countries have far less allergic population. It's said this is partly due to urban environments having more vitamin D deficiency as well as people being more exposed to more pathogens/etc during childhood outside of developed countries.
