Crinone (progesterone) is a vaginal gel that's used in fertility treatments. It's also used to help restart menstrual periods. This medication contains progesterone, which is a hormone that's naturally made in the body. You insert Crinone (progesterone) into the vagina using a prefilled applicator. For fertility, it's inserted once or twice a day. And for menstrual periods, the medication is inserted every other day. Some possible side effects include headache, stomach pain, and vaginal discharge.

Pros and cons of Crinone (progesterone)

- Used less often than the alternative progesterone vaginal insert
- Not as painful as progesterone injections
Cons
- Might cause breast growth and breast pain

Pharmacist tips for Crinone (progesterone)
- Crinone (progesterone) is available as a vaginal gel that comes in two different strengths: 4% and 8%. Using more of the 4% gel isn't the same as using the 8% strength. Don't use more Crinone (progesterone) than what your prescriber tells you.
- For fertility treatment: It's important to use Crinone (progesterone) for as long as prescribed. This helps raise your chances of getting and staying pregnant. Don't stop using this medication earlier than instructed. Tell your prescriber right away if you have any irregular menstrual bleeding; this can be a sign of a possible miscarriage.
- It's normal to see small, white drops in your vaginal discharge a few days after you use Crinone (progesterone). This is leftover gel that builds up after the medication has been absorbed. Wear a panty liner while you're using Crinone (progesterone) to help prevent this vaginal discharge from getting on your underwear.
- Don't use any other vaginal products within 6 hours of using Crinone (progesterone). Other vaginal products can affect how well the medication works.
How to use Crinone (progesterone):
- Take out the Crinone (progesterone) prefilled applicator from its packaging. Slide the plunger into the open end of the applicator, and then carefully remove the cap without pushing on the plunger.
- Lie on your back with your knees bent. Gently insert the applicator as far as you comfortably can into your vagina. Then, press the plunger all the way down to release the gel. Once you insert the medication into the vagina, you don't have to stay lying down.
- After you remove the applicator from your vagina, throw it away into the trash. It's okay if you see a small amount of gel left in the applicator.
Risks and warnings for Crinone (progesterone)
Crinone (progesterone) 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
- Risk factors: History of blood clots
Tell your prescriber before you start treatment with Crinone (progesterone) if you have a history of blood clots or medical problems caused by a blood clot (e.g., heart attack, stroke). You can't use this medication if you've had any kind of blood clot before.
Be aware of the signs and symptoms of a blood clot. Blood clots can sometimes lead to serious problems like heart attack or stroke. Call 911 or seek medical attention right away if you have pain in your legs or arms, chest pain, sudden severe headaches, trouble breathing, or sudden changes in your speech or vision. These can be signs of a blood clot.
Not FDA-approved for preventing miscarriage
Some fertility specialists might use progesterone and other forms of progesterone to help prevent a miscarriage (pregnancy loss). Crinone (progesterone) isn't FDA-approved to prevent miscarriages and hasn't been proven to work well for this purpose. Speak with your prescriber about your options for preventing miscarriages and follow your prescriber's recommendations very carefully.
Fluid buildup
- Risk factors: Heart failure | Kidney problems
It's possible for Crinone (progesterone) to cause extra fluid to build up in your body, especially in your legs, ankles, and feet. This is because progesterone plays a role in regulating fluid levels in the body.
Fluid buildup might be more likely to happen if you have certain medical conditions, like kidney problems or heart failure. The extra fluid can also worsen these conditions. Tell your prescriber if you have problems with fluid buildup or swelling before you start using Crinone (progesterone). Call your prescriber or get medical help right away if you notice unexplainable swelling, rapid weight gain, or sudden trouble breathing.
Worsening depression
- Risk factors: History of depression
Progesterone might play a role in causing negative emotions like depression. Research suggests that it's more likely due to changing progesterone levels in the body, such as during treatment with Crinone (progesterone). Tell your prescriber if you have or have had depression. Be aware of any changes in your mood or worsening symptoms of depression like feelings of hopelessness, fear, or despair. Speak to your prescriber if this happens while you're using Crinone (progesterone).
Possible rise in blood sugar levels
- Risk factors: Diabetes or prediabetes
Progesterone can raise blood sugar levels. If you have diabetes, it's possible for Crinone (progesterone) to make it harder for you to control your blood sugar. Let your prescriber know if you have diabetes or any problems with your blood sugar levels before you start using this medication.
