The Effect of Peppermint Oil Aromatherapy on Pain, Functional Capacity and Cost in Fibromyalgia Patients

Summary

This study was designed to evaluate the effect of topically applied peppermint oil (Mentha × piperita) on chronic pain and functional capacity experienced by fibromyalgia patients, as well as its cost-effectiveness.

Conditions

• Fibromyalgia
• Aromatherapy
• Cost

Interventions

OTHER

Peppermint Oil

This group of patients will be introduced to the tender points where chronic pain is detected in fibromyalgia patients, and the areas where these tender points are located will be divided into six regions, which will be identified with the patient. Subsequently, one drop of peppermint oil will be applied transdermally to the inner surface of the patient's forearm, and the application site will be monitored for allergic reactions such as redness or swelling. Patients who do not report any allergic reactions will apply 2 drops of peppermint oil to each area transdermally with their fingertip at 8:00 a.m. and 8:00 p.m. This application will be performed twice daily by the patient for 2 weeks. For areas inaccessible to the patient, a relative/caregiver will apply 2 drops of peppermint oil. The first dose will be administered by the researcher, who will demonstrate the application to the patient. The patient's opinions will be sought and questions answered during the first dose application

OTHER

sweet almond oil

Patients in this group will be introduced to the six sensitive areas where pain is felt, and the locations will be identified with the patient. The patient will apply 2 drops of sweet almond oil to each sensitive area twice daily, at 8:00 a.m. and 8:00 p.m., using their fingertip. This application will be performed twice daily by the patient for 2 weeks. For sensitive areas that the patient cannot access, a family member/caregiver will apply 2 drops of sweet almond oil. The first dose will be administered by the researcher, who will demonstrate the application to the patient. The patient's opinions will be sought and their questions answered during the first dose administration. Sweet almond oil will be provided to patients in dark-coloured glass bottles with droppers and secure caps that open with firm pressure. Patients will be advised to store sweet almond oil at room temperature.

OTHER

Duloxetine

Patients in this group will receive treatment planned by a rheumatologist. The pharmacological treatment plan will involve administering duloxetine 60 mg once daily for two weeks, a serotonin-noradrenaline reuptake inhibitor effective on descending pain inhibition pathways in fibromyalgia.
