Hello, There are many medicines that cause loss of libido but Tetrsayl (tetralysal) has no such indication. Loss of libido in women is commonly work stress, financial stress, anxiety, fatigue, weakness, fear of getting pregnant, physical illness, depression, emotional hurt with the sexual partner or dyspareunia (painful intercourse). Medical problems causing loss of libido are hormonal or thyroid issues. PCOS or menstrual issues, fear of getting sexually transmitted infections. Never indulge with multiple partners. Always perform safe sex. You are suggested to discuss with a Counselor, you may need medicines. You can even give a break & rest and resume your sex life after a couple of days. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nupur K, General & Family Physician
