<s>[INST] Hi, My dermatologist had prescribed me Finax tab and a particular hair oil for cure of hair loss. However after taking tabs for 1 month I noticed increased acidity and also lesser errection. I am afraid that it might lead to impotency so I have stopped taking this tablet now. Please suggest. [/INST] Hi, Yes, these are some common side effects of final. The common side effects of final include headache, weight gain, abdominal pain, and swelling of the fact and lips. Since it acts by preventing the formation of active male sex hormone, it can cause decreased interest in sexual intercourse, inability to have or keep an erection loss in sexual ability, desire, or performance. Ask your doctor for an alternate effective, but a safer medicine for hair loss like minoxidil lotion. Hope I have answered your question. Let me know if I can assist you further.  </s>
