Will be perform a RCT to compare pain measure on office hysteroscopy after pre-medication with oral analgesic. Patients will be alocate to oral sodic diclofenac, scopolamin or placebo. We will compare visual analog score of pain after the procedure.

Patients: patients with indication of office hysteroscopy to evaluate uterine intracavitary abnormality.

Interventions Group 1 (control) The patients will receive about 2 h prior to the procedure 2 placebo tablets.

Group 2 (diclofenac + scopolamine) The patients will receive about 2 h prior to the procedure 1 tablet of diclofenac sodium 50 mg and 1 tablet of scopolamine 2 mg.

Group 3 (diclofenac only). Patients will receive approximately 2 h prior to the procedure 1 tablet of diclofenac sodium 50 mg and 1 tablet of placebo.

Pain during and 30 minutes after a hysteroscopy will be measured through the visual analog pain scale of 10 centimeters, considering 0 (no pain) and 10 (unbearable pain or the greatest pain ever experienced). Acceptance of the procedure and assessed through the Likert 5-point scale: 1) totally disagree; 2) disagree; 3) I do not agree or disagree; 4) I agree and 5) I totally agree.There will also be a need for analgesia after the procedure, the time spent in the observation room and the onset of vagal symptoms such as dizziness, malaise, nausea, vomiting or syncope
