A survey-based, quasi-experimental study assessing a high-cannabidiol suppository for menstrual-related pain and discomfort

Abstract The endocannabinoid system is involved in gynecological functions, with cannabidiol (CBD) demonstrating promise for alleviating menstrual-related symptoms. This survey-based, quasi-experimental study assessed pro re nata (PRN) use of a commercially-available, hemp-derived, broad-spectrum, high-CBD (100 mg) vaginal suppository (Foria®) for menstrual-related pain and discomfort compared to a treatment-as-usual (TAU) group (CBD n = 77, TAU n = 230), with survey assessments collected at baseline and two monthly follow-ups (~2 menstrual cycles). The CBD group demonstrated significantly reduced frequency and severity of menstrual-related symptoms, impact of symptoms on daily functioning, need for analgesics, and number of analgesics used relative to the TAU group ( ps ≤ 0.032). Correlation analyses indicated a potential dose-dependent response, with increased suppository use associated with greater reduction of symptoms ( ps ≤ 0.025). Most CBD participants reported at least moderate improvement of symptoms (follow-up 1 = 72.9%, follow-up 2 = 81.1%). Future studies (including replication in randomized clinical trials) assessing pharmacokinetics/pharmacodynamics, mechanism(s) of action, efficacy for other gynecological indications, and potential adverse events (e.g., drug-drug interactions) are indicated.
