Dimetrum®: Indicated for the treatment of endometriosis1
Dimetrum (dienogest 2mg) is a fourth-generation synthetic progestin,4,5 derived from 19-nortestosterone, which is highly selective for progesterone receptors.6
Dienogest has:6
- Direct antiproliferative activities
- Immunologic activities4 and also causes atrophy of the endometriotic lesions.7

These are expected to contribute to the reduction of endometriosis-associated symptoms.6
Dimetrum® is generally well tolerated1,8,9
- Most adverse events were mild to moderate intensity9
- The most frequently reported undesirable effects under treatment with Dimetrum are headache (9.0%), breast discomfort (5.4%), depressed mood (5.1%) and acne (5.1%)1
- Adverse event discontinuation rates were low.9

For special warnings, precautions, and contraindications please consult the SPC.
Dimetrum® provides symptom control for your patients
Dimetrum reduces endometriosis-associated pelvic pain (EAPP)10
In a randomised, double-blind, placebo-controlled, multicentre study of 198 women, Dimetrum was significantly more effective than placebo in reducing EAPP at 12 weeks (p<0.0001).10
In a literature review, Dimetrum was shown to reduce multiple types of endometriosis-associated pain:8
- Pelvic pain
- Dysmenorrhea
- Dyspareunia
- Dysuria
- Dyschezia.
Dimetrum® provides disease control for your patients5,9,11
In a systematic review and meta-analysis, Dimetrum was shown to significantly reduce the rate of post-operative recurrence of endometriosis up to approximately three years, compared to post-operative patients not given Dimetrum (p<0.001).11
In an open-label, randomised, multicentre, 24-week comparative trial in 29 women with histologically confirmed endometriosis, Dimetrum was shown to significantly reduce the severity of endometriotic lesions compared to baseline (p<0.001).9
Dimetrum® compares well to established treatments6,8,12
Dimetrum has been shown to be as effective as gonadotropin-releasing hormone (GnRH) agonists.
In a study of 252 patients with confirmed endometriosis, dienogest 2 mg was as effective as Leuprolide acetate (LA) for treating EAPP at 24 weeks (p<0.0001).12
In a Japanese, randomised, double-blind, multicentre, controlled trial of 253 patients with endometriosis, dienogest 2 mg was as effective as intranasal buserelin acetate (BA) 900mcg in alleviating the symptoms of endometriosis at 24 weeks (p>0.05).6
Dimetrum® and cyst reduction
In a multicentre, prospective study of 81 patients with ovarian endometriosis, dienogest 2mg alone was significantly more effective in reducing the volume of endometriomas than a combined oral contraceptive (ethinyl estradiol 30 µg plus dienogest 2mg) (p<0.001).13
