Storing and Disposing of Your Medication
Keep your medication at room temperature in a dry location, avoiding storage in a bathroom. Ensure that all medications are stored in a safe place, out of the reach of children and pets. When disposing of unused or expired medication, do not flush it down the toilet or pour it down the drain unless specifically instructed to do so.

Safety & Warnings
BLACK BOX WARNING
Estrogens and progestins should not be used for the prevention of cardiovascular disease or dementia.
Cardiovascular Disorders and Probable Dementia
The Women's Health Initiative (WHI) study reported increased risks of stroke, deep vein thrombosis (DVT), pulmonary embolism (PE), and myocardial infarction (MI) in postmenopausal women receiving daily oral conjugated estrogens (CE) plus medroxyprogesterone acetate (MPA) compared to placebo. The WHI Memory Study (WHIMS), a substudy of WHI, reported an increased risk of probable dementia in postmenopausal women 65 years of age or older receiving CE plus MPA compared to placebo. It is unknown whether these findings apply to younger postmenopausal women.
Breast Cancer
The WHI study reported an increased risk of invasive breast cancer in postmenopausal women receiving daily oral CE plus MPA compared to placebo.

Do not start, stop, or change the dose of any medication without first consulting your doctor.
Precautions & Cautions
Before taking this medication, inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are using this drug. Your doctor may instruct you to stop taking this medication before certain surgical procedures. If you need to stop taking this medication, your doctor will advise you on when to resume treatment after your surgery or procedure.
Risk of Blood Clots
This medication may increase the risk of blood clots, which can be life-threatening. Blood clots can occur in the form of heart attack, stroke, or clots in the leg, lung, or eye. If you have a history of blood clots, inform your doctor. Additionally, if you will be immobile for an extended period, such as during long trips, bedrest after surgery, or illness, discuss this with your doctor, as it may increase your risk of blood clots.
Monitoring and Precautions
If you have diabetes, closely monitor your blood sugar levels. High triglyceride levels have been associated with this medication, so inform your doctor if you have a history of elevated triglycerides. Regularly undergo blood tests and bone density checks as directed by your doctor. Take calcium and vitamin D supplements as advised by your doctor.
Breast Cancer Risk
There may be an increased risk of breast cancer associated with this medication. Ensure you have regular breast exams, gynecology check-ups, and perform breast self-exams as instructed by your doctor.
Lab Tests and Skin Effects
This medication may affect certain laboratory tests, so inform all your healthcare providers and lab workers that you are taking this drug. Additionally, this medication may cause dark skin patches on your face, so avoid sun exposure, sunlamps, and tanning beds. Use sunscreen and protective clothing and eyewear to minimize sun exposure.
Special Considerations
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects.
Hormone Therapy (HT) Considerations
Drugs like this one have been associated with high blood pressure. Regularly check your blood pressure as directed by your doctor. Certain side effects, such as heart attack, stroke, breast cancer, and others, have been reported in people taking estrogen with progestin. The risk of these side effects may vary depending on factors like treatment duration, estrogen use with or without progestin, and other individual factors. Discuss the benefits and risks of using this medication with your doctor.

What to Do:
There is no specific antidote for medroxyprogesterone overdose. Treatment is symptomatic and supportive. In case of suspected overdose, contact a poison control center or emergency medical services immediately. Call 1-800-222-1222 for poison control.
Drug Interactions
Major Interactions
- Aminoglutethimide (may significantly decrease MPA plasma concentrations)
- CYP3A4 inducers (e.g., Rifampin, Carbamazepine, Phenytoin, Phenobarbital, St. John's Wort - may decrease MPA efficacy)
Moderate Interactions
- CYP3A4 inhibitors (e.g., Ketoconazole, Itraconazole, Ritonavir, Clarithromycin - may increase MPA plasma concentrations)
- Grapefruit juice (may increase MPA levels)
- Corticosteroids (MPA may decrease corticosteroid clearance)
- Cyclosporine (MPA may inhibit cyclosporine metabolism)
- Anticoagulants (MPA may alter coagulation parameters, requiring monitoring)
Minor Interactions
- Laboratory tests (may affect thyroid function tests, coagulation tests, glucose tolerance tests)
Monitoring
Baseline Monitoring
Rationale: To identify contraindications, risk factors (e.g., cardiovascular disease, breast cancer), and establish baseline health status.
Timing: Prior to initiation of therapy
Rationale: To establish baseline and monitor for potential hypertension.
Timing: Prior to initiation of therapy
Rationale: To screen for breast cancer, especially important due to increased risk with HRT.
Timing: Prior to initiation of therapy and as clinically indicated
Rationale: To assess cardiovascular risk factors.
Timing: Prior to initiation of therapy
Rationale: To assess hepatic function, as MPA is metabolized in the liver.
Timing: Prior to initiation of therapy, especially in patients with suspected hepatic impairment

Special Patient Groups
Pregnancy
Contraindicated in pregnancy. Medroxyprogesterone acetate is classified as Pregnancy Category X. There is evidence of fetal risk based on human experience, and the risks of use in pregnant women clearly outweigh any possible benefits.
Trimester-Specific Risks:
Lactation
Use with caution. Medroxyprogesterone is excreted in breast milk. While generally considered compatible with breastfeeding, observe the infant for any potential adverse effects (e.g., jaundice, breast enlargement). The American Academy of Pediatrics considers progestins compatible with breastfeeding.
Pediatric Use
Safety and efficacy have not been established in pediatric patients for the indications typically treated with 2.5mg oral tablets (e.g., HRT). Not recommended for use in prepubertal girls. Higher doses are used for specific pediatric conditions like precocious puberty, but not the 2.5mg oral tablet.
Geriatric Use
Use with caution. Women 65 years of age or older have an increased risk of probable dementia when receiving combined estrogen plus progestin therapy. Increased risk of stroke and DVT has also been observed in this population. Use the lowest effective dose for the shortest duration consistent with treatment goals and risks.
Clinical Information
Clinical Pearls
- Medroxyprogesterone 2.5mg is most commonly used as part of continuous combined hormone replacement therapy (HRT) to protect the endometrium from estrogen-induced hyperplasia in postmenopausal women with an intact uterus.
- Always assess for contraindications (e.g., undiagnosed abnormal genital bleeding, breast cancer, active DVT/PE, severe liver disease) before initiating therapy.
- Patients should be advised of the Black Box Warnings regarding cardiovascular events, breast cancer, and probable dementia, especially with long-term use in HRT.
- Regular monitoring, including annual physical exams, breast exams, and mammograms, is crucial.
- Any new or unusual vaginal bleeding should be promptly investigated to rule out endometrial pathology.
- Consider the lowest effective dose for the shortest duration consistent with treatment goals and risks.
Alternative Therapies
- Other progestins (e.g., micronized progesterone, norethindrone)
- Selective Estrogen Receptor Modulators (SERMs) for specific indications (e.g., tamoxifen, raloxifene)
- Non-hormonal therapies for menopausal symptoms (e.g., SSRIs/SNRIs, gabapentin, clonidine)
- For abnormal uterine bleeding: other hormonal therapies (e.g., oral contraceptives, IUDs), surgical options.
