Estrogen helps moisten the lining of your vagina. During menopause, your estrogen levels drop, which cause your vagina to become dry and irritated. This can make sex painful and uncomfortable.

Pharmacist tips for Osphena (ospemifene)
- Take Osphena (ospemifene) once a day with food. Taking the medication with food helps it get absorbed into the body better.
- It's normal to experience hot flashes, vaginal discharge, and sweating while you're taking Osphena (ospemifene). Talk to a healthcare professional if these symptoms become too bothersome for you.
- If you have a hot flash, it's recommended to limit how much spicy foods you eat or how much alcohol and caffeine you drink. These foods and beverages can make hot flashes feel worse. Keep a fan nearby and keep your room cool to help you feel more comfortable when you get hot flashes.
- Tell your prescriber about any planned surgeries or bedrest. Some types of surgeries and periods of time when you won't be moving much can put you at risk for blood clots while you're taking Osphena (ospemifene). Your prescriber can tell you when to stop taking Osphena (ospemifene) — typically at least 4 to 6 weeks before — and when you can restart the medication. This helps lower the risk for blood clots.
- Don't take other estrogen medications to help with menopause symptoms with Osphena (ospemifene). We don't know how safe it is to take these medications at the same time.
Risks and warnings for Osphena (ospemifene)
Osphena (ospemifene) 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.
Risk for blood clots, stroke, or heart attack
- Risk factors: Personal or family history of blood clots | High blood pressure | High blood sugar (diabetes) | High cholesterol | Tobacco use | Systemic lupus erythematosus (SLE)
Though rare, some people who took Osphena (ospemifene) developed a blood clot during clinical studies with the medication. Sometimes, these blood clots led to a heart attack or stroke. Let your prescriber know about your full medical history so they can check your risk for blood clots before you start taking Osphena (ospemifene).
Be aware of the signs and symptoms of a blood clot, heart attack, and stroke.
- Blood clot in arm or leg: swelling or pain in the arm or leg
- Blood clot in the lung: chest pain, trouble breathing
- 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
Stop taking Osphena (ospemifene) and get medical help right away if you have any signs or symptoms of a blood clot.
Uterine or endometrial cancer
- Risk factors: Estrogen therapy without additional progestin | People with a uterus | Using estrogen therapy for more than 1 year
Osphena (ospemifene) acts like estrogen in your uterus. It can thicken and change the lining of your uterus, called the endometrium. Uncontrolled growth of the uterus lining can cause uterine or endometrial cancer in people with a healthy uterus. In general, the risk for endometrial cancer is higher in people who take estrogen therapy without progestin (another hormone) to balance out estrogen's effect on the growth of the uterine lining.
Although studies found that Osphena (ospemifene) thickens the lining of the uterus a little, there haven't been any reported cases of endometrial cancer in people who've taken the medication yet. And taking a progestin with Osphena (ospemifene) hasn't been studied, so it's not clear whether taking a progestin with this medication is beneficial.
To be safe, be aware of warning symptoms of uterine (endometrial) cancer, including vaginal bleeding that doesn't go away or keeps coming back or pelvic pain. Let your healthcare team know if you notice any unusual vaginal bleeding. Speak with your prescriber if you're worried about Osphena (ospemifene) and uterine cancer.
Breast cancer
- Risk factors: History of breast cancer
Osphena (ospemifene) hasn't been studied in people with breast cancer. It's unclear whether this medication can affect your risk for breast cancer. To be safe, you shouldn't take Osphena (ospemifene) if you currently have or have had breast cancer in the past. Remember to regularly do a breast cancer self-exam to check for any changes and get your scheduled breast scans (mammograms) done. Let your prescriber or primary care provider know if you notice any unusual changes to your breasts.
