Pharmacist tips for Climara (estradiol patch)

pharmacist
  • Pick a day to change your Climara (estradiol patch) and mark it on your calendar each week. Remove your patch after 7 days and apply a new one on the same day each week.
  • Use a different spot each time you apply Climara (estradiol patch) to avoid skin irritation. Don't use the same area twice in the same week.
  • Apply Climara (estradiol patch) to your lower stomach or upper buttocks. But avoid your waistline, since tight clothing can cause it to fall off.
  • When removing Climara (estradiol patch), fold the patch in half with the sticky sides together before throwing it away. This helps prevent exposing others to any medication left on the patches. Never flush it down the toilet.
  • If any sticky residue stays on your skin after removing Climara (estradiol patch), let the area dry for 15 minutes, then gently rub it off with some cream or lotion.
  • Swimming, showering, bathing, or using a sauna can cause Climara (estradiol patch) to fall off. If it does, try reapplying it to another area of your lower stomach or upper buttocks. If it doesn't stick, apply a new patch but stay on your regular schedule.
  • Let your prescriber know if you experience unusual vaginal bleeding, lumps in your breast, changes to your vision, or severe headaches after starting Climara (estradiol patch). These are more serious side effects and could be a sign of a bigger health problem.
  • Be sure to attend your follow-up appointments so you and your prescriber can discuss whether you still need Climara (estradiol patch).

How to apply Climara (estradiol patch):

  • Remove the patch from the pouch and peel off the protective backing without touching the sticky part.
  • Apply the patch to clean, dry, hairless skin on your lower stomach or upper buttocks. Never put it on your breasts or broken skin (e.g., cuts, scrapes, wounds).
  • Press the patch firmly to your skin for 10 seconds. Rub the edges to make sure that it sticks properly.

Common questions about Climara (estradiol patch)

You should place Climara (estradiol patch) on a clean, dry area of your lower stomach or upper buttocks, but avoid the waistline so the patch doesn't rub off. Rotate where you apply it each time and wait at least one week before using the same spot again.

The highest dose Climara (estradiol patch) comes in is 0.1 mg/day.

It's generally not recommended to cut patches like Climara (estradiol patch) in half, because this can change how the medication is released into your body. Climara (estradiol patch) comes in different doses, so your prescriber can help you to find the right one that works best for you.

It can. In studies, some people reported weight gain as a side effect when using Climara (estradiol patch). One reason is that the medication might cause your body to hold onto extra fluid, which can appear as water weight. Keep in mind that weight gain is also common during menopause. If you've been gaining weight since you started Climara (estradiol patch) and it concerns you, speak with your prescriber.

Yes. Climara (estradiol patch) is a bioidentical hormone.Bioidentical hormones are chemically similar to the hormones your body naturally makes.

Climara (estradiol patch) contains only estrogen, while Climara Pro contains both estrogen and a progestin called levonorgestrel. If you have a healthy uterus, it's recommended to take a progestin along with estrogen to help protect the uterine lining and lower the risk of uterine (endometrial) cancer. Both patches are hormonal replacement therapies that you apply to the skin once a week. Speak with your prescriber to learn more about comparing these different patches.

As soon as you apply the patch, your estrogen levels will start to go up. But it can take time to notice an improvement in your symptoms. Studies show that Climara (estradiol patch) can start working within 1-2 weeks after you start it. And changes in bone mineral density were seen 6 months after starting the medication. Be sure to attend all of your follow-up appointments so your prescriber can check how well the medication is working for you.

If Climara (estradiol patch) falls off, try to reapply it. If it won't stick, put on a new patch in a different area on your lower stomach or upper buttocks. Then, keep following your regular schedule for applying patches.

Risks and warnings for Climara (estradiol patch)

Climara (estradiol patch) 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 and related complications (e.g., heart attack, stroke)

  • Risk factors: Personal or family history of blood clots | High blood pressure | Diabetes (high blood sugar) | High cholesterol | Tobacco use | Considered obese | Systemic lupus erythematosus (SLE)

Black Box WarningClimara (estradiol patch) can raise the risk of blood clots. These clots can block the blood flow to other parts of the body, like the leg, lungs, heart, or brain. Some clots can lead to dangerous complications, like heart attack or stroke.

Get emergency help right away if you have any signs of a blood clot.

  • Brain: weakness or numbness in your arms, legs, or face on one side of the body, trouble speaking, blurred vision, dizziness, loss of balance, trouble walking, or confusion
  • Eyes: trouble seeing, bulging eye, double vision
  • Heart: chest pain, sweating, nausea, or dizziness
  • Lungs: trouble breathing, chest pain, or cough
  • Legs: cramps, swelling, pain, or muscle tightness

If you need to have surgery, tell your care team you're taking Climara (estradiol patch). They might have you stop taking it 4 to 6 weeks before surgery to lower your risk of blood clots.

Uterine (endometrial) cancer

  • Risk factors: Using Climara (estradiol patch) without progestin for people with a uterus | Long-term use of Climara (estradiol patch)

Black Box WarningVaginal bleeding after menopause can be a warning sign of uterine (endometrial) cancer, so let your prescriber know if you notice any unusual bleeding. Using estrogen replacement therapy, like the Climara (estradiol patch), for more than a year can raise your risk of this cancer. If you still have your uterus, taking another hormone called a progestin along with Climara (estradiol patch) can help lower this risk. Progestin works by balancing estrogen's effects and slowing the growth of the uterine lining.

Breast cancer

  • Risk factors: Personal or family history of breast cancer | Using estrogen and progestin together | Long-term use of Climara (estradiol patch)

Black Box WarningTaking Climara (estradiol patch) with a progestin can raise your risk of breast cancer. The longer you use them, the higher the risk. That's why it's best to use this medication for the shortest time needed. You should have a breast exam every year with a healthcare professional and do monthly self-exams to check for any changes. In addition, check with your prescriber about when to schedule mammograms. Call your prescriber if you notice any abnormal changes or feel lumps, pain, or swelling in your breasts.

Ovarian cancer

  • Risk factors: Using estrogen and progestin together

Taking Climara (estradiol patch) with a progestin might raise your risk of ovarian cancer. If you're concerned about this risk, talk to your prescriber. Let your prescriber or gynecologist know if you have unusual vaginal bleeding, vaginal discharge, or pelvic pain, as these could be signs of ovarian cancer.

Dementia

  • Risk factors: Older adults

Black Box Warning Taking estrogen alone or with progestin might raise the risk of dementia, especially in older adults. Talk to your prescriber if you have concerns about memory problems or dementia while taking this medication.

Gallbladder and liver problems

  • Risk factors: History of liver problems or jaundice

Climara (estradiol patch) can cause gallbladder problems, and some people have even needed to have their gallbladder removed after starting this medication. If you have stomach pain, nausea or vomiting that won't go away, fever, or yellowing of the skin and eyes (jaundice), tell your prescriber right away or get medical attention.

Since Climara (estradiol patch) is broken down by your liver, you might have more side effects if your liver isn’t working properly. If you have or have had any problems with your liver, including liver issues during pregnancy, you shouldn't use this medication.

Vision problems

Although very rare, some people taking estrogens had vision problems from a blood clot in the eye. Stop taking Climara (estradiol patch) right away and tell your prescriber if you have sudden vision loss, bulging eyes, double vision, or migraines.

High triglycerides

  • Risk factors: High levels of triglycerides

Estrogens like Climara (estradiol patch) can raise your blood fat levels (triglycerides), which can lead to heart problems or inflammation of the pancreas. If you experience sudden stomach or back pain, nausea, vomiting, sudden weight loss, or a fast heart rate, contact your prescriber or get medical care right away.

Low thyroid hormone levels (hypothyroidism)

  • Risk factors: Low thyroid hormone levels

Climara (estradiol patch) can affect thyroid hormone levels in your blood. If your thyroid is healthy, your body can adjust and keep your hormone levels normal. But if you take thyroid medication, you may need a higher dose while using Climara (estradiol patch). Your prescriber will monitor your thyroid levels during treatment to make sure they stay in a healthy range.

Fluid Retention

  • Risk factors: History of heart or kidney problems

Using estrogen products like Climara (estradiol patch) might cause fluid retention, or edema. The risk is higher if you have heart conditions, like congestive heart failure, or kidney damage. If you notice unusual swelling in any part of your body or sudden weight gain, let your prescriber know. If fluid retention becomes a serious problem, your prescriber might stop your treatment with Climara (estradiol patch).

Worsening of other health conditions

Tell your prescriber about all the medical conditions you have before taking Climara (estradiol patch). This medication can make some health conditions worse. This includes asthma, diabetes, epilepsy, migraine, and lupus, among others. It can also affect people with hypoparathyroidism or hereditary angioedema.
