Nursing implications

Nursing assessment

  • Monitor BP periodically during therapy.
    • Assess patient’s usual menstrual history. Administration of drug may begin on any day of cycle in patients with amenorrhea and on day 16 or 21 of cycle in patients with dysfunctional bleeding.
    • Monitor intake and output ratios and weekly weight. Report significant discrepancies or steady weight gain.
  • Lab Test Considerations: Monitor hepatic function before and periodically during therapy.
    • May cause ↑ alkaline phosphatase levels. May ↓ pregnanediol excretion concentrations.
    • May cause ↑ serum LDL concentrations or ↓ HDL concentrations.
    • May alter thyroid hormone assays.

Potential Nursing Diagnoses

Sexual dysfunction (Indications)
Ineffective tissue perfusion (Side Effects)


  • Do not confuse Depo-Provera with Depo-subQ Provera 104. Do not confuse Provera (medroxyprogesterone) with Proscar (finasteride) or Prozac (fluoxetine).
    • Only the 150 mg/mL vial should be used for contraception.
    • Injectable medroxyprogesterone may lead to bone loss, especially in women younger than 21 yr. Injectable medroxyprogesterone should be used for >2 yr only if other methods of contraception are inadequate. If used long term, women should use supplemental calcium and vitamin D, and monitor bone mineral density.
  • Subcutaneous: Shake vigorously before use to form a uniform suspension. Inject slowly (over 5–7 seconds) at a 45° angle into fatty area of anterior thigh or abdomen every 12 to 14 wk. If more than 14 wk elapse between injections, rule out pregnancy prior to administration. Do not rub area after injection.
    • When switching from other hormonal contraceptives, administer within dosing period (7 days after taking last active pill, removing patch or ring, or within the dosing period for IM injection).
  • Intramuscular: Shake vial vigorously before preparing IM dose. Administer deep IM into gluteal or deltoid muscle. If period between injections is >14 wk, determine that patient is not pregnant before administering the drug.
    • In patients with cancer, IM dose may initially be required weekly. Once stabilized, IM dose may be required only monthly.

Patient/Family Teaching

  • Explain the dose schedule. Instruct patient to take medication at the same time each day. Take missed doses as soon as remembered, but do not double doses.
    • Advise patients receiving medroxyprogesterone for menstrual dysfunction to anticipate withdrawal bleeding 3–7 days after discontinuing medication.
    • Review patient package insert (PPI) with patient. Emphasize the importance of notifying health care professional if the following side effects occur: visual changes, sudden weakness, incoordination, difficulty with speech, headache, leg or calf pain, shortness of breath, chest pain, changes in vaginal bleeding pattern, yellow skin, swelling of extremities, depression, or rash. Patients receiving medroxyprogesterone for cancer may not receive PPI.
    • Advise patient to keep a 1-mo supply of medroxyprogesterone available at all times.
    • Instruct patient in correct method of monthly breast self-examination. Increased breast tenderness may occur.
    • Advise patient that gingival bleeding may occur. Instruct patient to use good oral hygiene and to receive regular dental care and examinations.
    • Medroxyprogesterone may cause melasma (brown patches of discoloration) on face when patient is exposed to sunlight. Advise patient to avoid sun exposure and to wear sunscreen or protective clothing when outdoors.
    • Instruct patient to notify health care professional if menstrual period is missed or if pregnancy is suspected. Patient should not attempt conception for 3 mo after discontinuing medication in order to decrease risk to fetus.
    • Emphasize the importance of routine follow-up physical exams, including BP; breast, abdomen, and pelvic exams; and Papanicolaou smears every 6–12 mo.
  • Intramuscular: Subcutaneous: Advise patient to maintain adequate amounts of dietary calcium and vitamin D to help prevent bone loss.

Evaluation/Desired Outcomes

  • Regular menstrual periods.
  • Decrease in endometrial hyperplasia in postmenopausal women receiving concurrent estrogen.
  • Control of the spread of endometrial or renal cancer.
  • Prevention of pregnancy.
