"The scourge of premenstrual tension, which affects more than half of women and causes physical as well as emotional trauma, could soon be eradicated by a safe, low-dose pill, scientists said yesterday. A laboratory-based study has found that very low doses of the anti-depression drug Prozac can eliminate the symptoms of premenstrual syndrome, which include mood swings, tiredness, irritability, headaches and joint pains. The scientist leading the research said the findings, which have so far been observed in laboratory rats, are strong enough to warrant a full-scale clinical trial with Prozac given that the drug has already undergone the necessary safety tests at the higher doses needed to treat depression."
