Premature ejaculation is a general term, not a medical one. It is a question of timing with female sexual partner. It is true that some people have early orgasmic response in relation to one partner. The same person may not have the same problem with another sexual partner. It is not a disease. There are many non-drug methods to delay ejaculation. Details can be obtained in any good book on sex meant for lay people.
Flucan is the brand name of a medicine called fluconazole. It is indicated in the treatment of fungal infections. Its side effects include damage to liver. Flucan is not even remotely connected with sexual dysfunction. I cannot see any scientific reason to prescribe this medicine to you, that too, for such a long period unless you are suffering from serious, systemic fungal infection.
