MEDICAL TREATMENT OF PMS: PROGESTERONE/PROGESTOGEN THERAPY
Saturday, April 16th, 2011Progesterone therapy is one of the most controversial therapies for PMS, yet it is one of the most widely used. Supporters of British researcher Dr Katharina Dalton, who has researched the treatment for over 30 years, are largely responsible for its widespread use.Despite the enthusiasm, proper studies of progesterone versus a dummy pill have failed to show any benefit with this hormone therapy. But because a few women do seem to benefit many doctors feel if s worth a try if other methods have failed.Dr Dalton and other doctors who follow her teaching believe that natural progesterone should not be taken by mouth because it breaks down before it has a chance to work. So vaginal or rectal ‘suppositories’ – a gel-based ‘pellet inserted into the vagina or rectum – are used instead. Sometimes daily injections are given and work is being done on a tablet form.The dose is 400mg to 800mg taken twice a day, starting on day 12 of the cycle. Treatment usually lasts for a minimum of six months but some women may need to carry on for up to two years or until the menopause if they are over 40.Progestogens are synthetic forms of progesterone which can be taken as tablets by mouth.Dydrogesterone is the type of progestogen most often prescribed. The main drawback of progestogens is that some women find they tend to produce more side-effects than natural progesterone, especially weight gain and irregular periods.Critics of progestogen treatment say its chemical structure is so different from that of progesterone that it does not work and actually makes PMS worse Once again, though, there have been no studies to support or refute this claim.*47\120\4*
