In some cases, medical cannabis may be prescribed as a suppository or a pessary. The difference is where the medicine is placed: a suppository is inserted into the rectum, and a pessary is inserted into the vagina.
These specialist formats can only be prescribed after an assessment by a specialist clinical team, and they are prepared to controlled pharmaceutical standards.
A clinician may suggest a suppository or pessary if other forms of medical cannabis are not suitable – for example, if a patient cannot easily take medicines by mouth. They may also be considered when symptoms affect the pelvis, rectum, reproductive organs or digestive system, where a more localised approach may be appropriate.
Your clinician will explain how to use your medicine during your consultation. Instructions are also included on your dispensing label and in any patient information supplied with your medicine.
A suppository is a dose of medicine that’s inserted into the rectum, where it will dissolve and release the medication.
A pessary is a dose of medicine that’s inserted into the vagina, where it will dissolve and release the medication.
Suppositories and pessaries release medication after they are inserted into the rectum or vagina. Once in place, they dissolve or melt at body temperature, releasing the active ingredient. Depending on the medicine, it may work in the area where it is applied or be absorbed into the bloodstream to work throughout the body.
The time it takes for a medical cannabis suppository or pessary to work can vary depending on the formulation, dose and individual patient factors. Once inserted, the product dissolves or melts, releasing cannabinoids that may be absorbed through local tissues. Some people may notice effects relatively quickly, while for others it may take longer. The onset and duration of effects can vary between individuals.
