progesterone
Progesterone is an injection used to treat people who aren't getting their period or have abnormal bleeding due to hormone imbalance. It belongs to a group of medications called progestins and works by replacing progesterone hormone that's naturally made in the body. The medication is typically injected into the muscle daily for 6-8 days in a row. Potential side effects include pain at the injection site, weight gain or weight loss, and breast tenderness.

Pharmacist tips for Progesterone
- The dosing schedule can be different depending on what you’re using progesterone for, so take it exactly the way your prescriber tells you.
- Progesterone can be given at home. You don't need to go to your prescriber's office to receive your doses. But you'll need to be taught how to correctly give yourself the injections.
- Progesterone is commonly injected in the upper outer buttock area, but your prescriber might also suggest areas. Make sure to rotate injection sites each time to lessen injection-site reactions.
- Progesterone contains sesame oil, so tell your prescriber if you're allergic to sesame oil or sesame seeds. Speak with your care team about all of your allergies so they can make sure this medication is safe for you.
- Progesterone can make you feel tired or dizzy. Don't drive or perform dangerous activities without seeing how it affects you first.
- If you're taking progesterone to regulate your period, your period should start within 3 days after the last injection. If your period doesn't start by this point, let your prescriber know. If you've been sexually active, you should also take a pregnancy test.
- Let your prescriber know if you experience unusual or heavy vaginal bleeding, lumps in your breast, changes to your vision, or severe headaches after starting progesterone. These are not typical side effects and could be a sign of more serious problems.
- Progesterone is a multi-use vial, so you'll draw up the many doses from the same vial. Make sure you use a new needle and syringe for each injection to prevent contamination.
- Throw away used syringes and needles in a sharps container, which might be provided by your prescriber or purchased at most pharmacies. Never throw needles and syringes in the regular trash.
- Store the progesterone vial at room temperature, even after it's been opened. Be sure to throw away the opened vial after 28 days, unless the product label instructs otherwise.
Common questions about Progesterone
Some people have reported gaining weight while taking Progesterone. But research is mixed, since some people have also reported weight loss. These changes in weight can sometimes be caused by your body holding on to extra fluid. Tell your prescriber if you notice you're gaining weight so they can help you determine the cause and provide suggestions.
Research suggests that Progesterone might make you feel more tired. But there isn't enough information to know if it causes fatigue. Talk to your prescriber if you're feeling more tired than usual.
If you're taking Progesterone because you don't get periods, you can expect a withdrawal bleed (like a period) around 48 to 72 hours after your last injection. Your body might have normal menstrual cycles after this. Tell your prescriber if you don't have any bleeding within a few days after using this medication for 8 days in a row.
Progesterone is sometimes used off-label for in vitro fertilization (IVF) to help people get pregnant. Its purpose is to prepare the lining of the uterus (womb) for the implantation of a fertilized egg. For more information about using progesterone for IVF, talk with your healthcare professional.

Risks and warnings for Progesterone
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: Taking progesterone with estrogens | Personal or family history of blood clots | High blood pressure | Diabetes | High cholesterol | Smoking | Obesity | Systemic lupus erythematosus (SLE)
Progesterone can raise your risk of blood clots, especially when taken with estrogen medications. This can be very dangerous and lead to heart attack, stroke, or pulmonary embolism (life-threatening blood clot in the lungs). Be sure to discuss all your medical conditions with your prescriber before starting progesterone. Call 911 or seek immediate medical attention if you have pain in your legs or arms, chest pain, sudden severe headaches, trouble breathing, or sudden changes in your speech.
Vision problems
Progesterone can cause retinal thrombosis, or a blood clot in the eyes. Speak to your prescriber right away if you notice changes in your vision, sudden vision loss, bulging eyes, double vision, or migraine.
Fluid buildup
- Risk factors: Heart failure | Kidney problems
Progesterone can cause extra fluid to build up in your body, especially in your legs, ankles, and feet. This is more likely to happen if you have certain conditions like kidney problems or heart failure. The extra fluid can cause these other conditions to get worse. If you know you have problems with fluid buildup or swelling, tell your prescriber before you start using progesterone. Call your prescriber or seek medical help right away if you notice unexplainable swelling, unexplained weight gain, or sudden trouble breathing.
Pneumonia
Very rarely, progesterone can cause a certain type of pneumonia. In some cases, this type of pneumonia can affect your breathing, which can be life-threatening. This is most likely to happen during the first 2 to 4 weeks after you start using the medication. It usually goes away when progesterone is stopped or if corticosteroids are taken. If you have sudden shortness of breath along with a fever, cough, and chest pain that gets worse when you take a deep breath, contact your care team or seek medical care right away.
