Prempro

conjugated estrogens / medroxyprogesterone
Used for Menopause, Osteoporosis

Prempro is a combination hormone replacement therapy (HRT) for postmenopausal women who still have a uterus. It's used to relieve vaginal dryness and hot flashes caused by menopause and to help prevent osteoporosis after menopause. The medication contains estrogen and a progestin in one tablet that's taken by mouth once a day. Common side effects include breast pain, back pain, and headache.

Premphase contains the same hormones but uses a different dosing schedule: estrogen alone for the first 14 days, followed by estrogen plus progestin for the next 14 days.

What is Prempro?

What is Prempro used for?

How Prempro works

Prempro is a combination of two medications:

  • Conjugated estrogens is a mixture of estrogens. It replaces the estrogen your body loses during menopause. This helps relieve hot flashes and vaginal symptoms and can slow bone loss.
  • Medroxyprogesterone is a progestin that acts like the hormone progesterone. It helps balance the effect of estrogen on your uterine lining, lowering the risk of changes that can lead to cancer.

Pharmacist tips for Prempro

pharmacist
  • You can take Prempro with or without food. If you have nausea, try taking it with food. For best results, take your dose around the same time each day.
  • Premphase comes with two different types of tablets that must be taken in the correct order. Follow the order shown on the package, and ask your pharmacist if you're unsure how to take it.
  • If you miss a dose of Prempro, take it as soon as you remember. If it's almost time for your next dose, skip the missed dose and don't take 2 doses at once.
  • You might start to notice relief from menopause symptoms within a few weeks of starting Prempro. Talk to your prescriber if your symptoms aren't improving after about a month.
  • Check in with your prescriber regularly while taking Prempro to make sure you still need treatment. Long-term use can raise your risk of serious problems, such as breast cancer, heart attack, and blood clots, so use the lowest effective dose for the shortest time needed.
  • Tell your prescriber right away if you have unusual vaginal bleeding, a breast lump, vision changes, or severe headaches while taking Prempro. These could be signs of a more serious problem.
  • Tell your prescriber and pharmacist about all medications and supplements you take before starting Prempro. Products such as St. John's wort, rifampin, ketoconazole, and clarithromycin can affect your hormone levels.
  • Tell your prescriber if you take thyroid replacement medication while taking Prempro. Estrogen can affect your thyroid hormone levels, so you might need extra blood tests or a change in your thyroid medication dose.

Risks and warnings for Prempro

Prempro can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Blood clots, heart attacks, and strokes

  • Risk factors: Personal or family history of blood clots | High blood pressure | Diabetes | High cholesterol | Smoking | People who identify as obese | Systemic lupus erythematosus (SLE)

Black Box Warning HRTs like Prempro can increase your risk of blood clots because they contains estrogen. Sometimes, these blood clots can be very dangerous and lead to a heart attack, stroke, or pulmonary embolism (blood clot in the lungs).

Tell your prescriber about your full medical history so they can check your risk for blood clots. Also tell your prescriber about any planned procedures or long periods of bedrest. Your prescriber will let you know when to stop Prempro before your procedure and when to restart it afterwards to lessen your risk for blood clots. In general, you should take the lowest dose of Prempro for the shortest period of time possible to lower your risk for blood clots.

Be aware of the signs and symptoms of a blood clot and related complications.

  • Blood clot in arm or leg: swelling or pain in the arm or leg
  • Blood clot in the lung: chest pain, trouble breathing
  • Blood clot in the eye: sudden partial or complete vision loss, bulging eyes, double vision
  • Heart attack (blood clot near the heart): chest pain, arm pain, shortness of breath, a cold sweat, lightheadedness
  • Stroke (blood clot in the brain): sudden weakness on one side of the body, drooping face, trouble breathing, bad headache, changes in speech or vision

Get medical help right away if you have any signs or symptoms of a blood clot.

Breast cancer

  • Risk factors: Personal or family history of breast cancer | Long-term use of Prempro

Black Box Warning Taking HRT with estrogen and progestin, like Prempro, can raise your risk of breast cancer. Your risk can increase the longer you use the medication, so it's recommended to use the lowest effective dose for the shortest time needed.

Talk to your prescriber about your risk, especially if you or a family member has had breast cancer. Keep up with recommended breast cancer screenings, including mammograms. Let your prescriber know if you notice a breast lump or other unusual breast changes.

Uterine (endometrial) cancer

  • Risk factors: Estrogen therapy without additional progestin | People with a healthy uterus | Taking Prempro for a long time

Black Box Warning Vaginal bleeding after menopause can be a warning sign of uterine (endometrial) cancer, so let your prescriber know if you notice any unusual bleeding. Even though Prempro contains a progestin to help protect your uterus, unusual bleeding still needs to be checked.

Ovarian cancer

HRTs like Prempro could raise your risk of ovarian cancer. Although this risk is small, it’s important to be aware of possible symptoms.

Tell your care team if you notice unusual vaginal bleeding, abnormal vaginal discharge, pelvic pain, bloating, or a feeling of fullness that doesn’t go away. These can be signs of ovarian cancer and should be checked by your care team.

Dementia

  • Risk factors: Age 65 years or older

Black Box Warning People taking medications that contain estrogen, such as Prempro, might have a higher risk of dementia. This risk has been seen in women who start hormone therapy at age 65 or older.

Be aware of the early signs and symptoms of dementia, such as becoming confused or more forgetful, getting lost, and having trouble doing familiar things at home or at work. Speak with your prescriber if the risk for dementia worries you.

Liver and gallbladder problems

  • Risk factors: History of liver problems or jaundice

The risk for gallbladder problems is higher for people who've gone through menopause and are taking estrogen therapy like Prempro. Sometimes, these gallbladder problems require surgery. Let your prescriber know if you've previously had jaundice (yellowing of your skin or whites of the eyes). And tell your care team if you start having jaundice, stomach pain that doesn't go away, nausea, or vomiting while you're taking this medication. These can be signs of liver damage or gallbladder problems.

Changes in calcium levels in the blood

  • Risk factors: Breast cancer | Cancer that has spread to the bones | Low parathyroid hormone levels

Prempro can change the calcium levels in the blood. People with breast cancer and people with cancer that's spread to the bones are at higher risk of dangerously high calcium levels while they're taking estrogens. Tell your care team if you have any symptoms of high calcium levels, including tiredness, muscle weakness, bone pain, nausea, constipation, and thirst.

On the other hand, estrogen therapy can make calcium levels drop in people with low parathyroid hormone levels. Contact your care team if you have symptoms of low calcium levels, such as muscle cramps; brittle nails; and tingling in your fingers, toes, or lips.

Vision problems

Although very rare, some people taking estrogens have experienced vision problems caused by a blood clot in the eyes. If you have sudden partial or complete vision loss, bulging eyes, double vision, or migraines, stop Prempro and tell your care team.

High triglycerides (fat) levels

  • Risk factors: History of high triglyceride levels in the blood

Let your prescriber know if you have a history of having high triglyceride levels. It's possible that the estrogen in Prempro can raise the amount of triglycerides (fat) in the blood. And having too much in the blood can lead to swelling of the pancreas (pancreatitis). Tell your care team right away if you have symptoms of pancreatitis, like sudden stomach or back pain, nausea, vomiting, fever, or weakness.

Low thyroid hormone levels

  • Risk factors: Conditions that cause low thyroid hormone levels

The estrogen in Prempro can cause changes to the thyroid hormone levels in the body. It's harder for the body to adjust to these changes for people with low thyroid hormone levels (hypothyroidism) than for an average person. If you take thyroid replacement medication for your thyroid condition, you might need a higher dose of your thyroid medication. Work with your prescriber to adjust the dose of your thyroid medication.

Buildup of fluids in your body (fluid retention)

  • Risk factors: History of heart or kidney problems

Estrogen/progestin combination therapies like Prempro can make your body hold onto extra fluids. This can sometimes cause swelling of your hands and feet. Fluid retention can worsen symptoms of certain heart conditions, like heart failure, and kidney damage. Tell your healthcare team if you notice any signs of worsening fluid retention (e.g., swelling, sudden weight gain) while you're taking Prempro if you have heart or kidney problems.

Severe allergic reaction

Prempro can rarely cause serious allergic reactions, including anaphylaxis and facial or throat swelling. These reactions can happen within minutes to hours after taking a dose. Symptoms can include hives, itching, swelling of your face, lips, or tongue, trouble breathing, stomach pain, or vomiting. Get emergency medical help right away if you develop these symptoms.

Worsening of certain other health conditions

Before you start Prempro, speak with your care team about your medical history. Taking estrogen-containing medications can worsen certain health conditions and you might require closer follow up. These health conditions include diabetes, asthma, migraine, lupus, seizures, and hereditary angioedema.
