Progesterone works like a natural “support hormone” for women’s bodies. After ovulation, it tells the womb to get ready for a baby by making the lining thicker and more stable. It also keeps the lining from growing too much when estrogen is used, so the uterus stays healthy and balanced.

Pregnancy

Progesterone is the key pregnancy hormone that keeps the womb lining stable and ready for a baby. It prevents early contractions and supports the placenta, helping maintain a healthy pregnancy.

Breastfeeding

Progesterone is safe to use while breastfeeding because only tiny amounts pass into breast milk and do not affect the baby. Doctors often prefer progesterone-only options in breastfeeding patients over other alternatives since they do not affect milk supply.

Kidney and Liver Problems

Progesterone should be avoided in liver disease because it can worsen liver function. In kidney patients, it may be used cautiously, as fluid retention and blood pressure changes. It is recommended to consult a doctor before using it.

Heart Patients

Progesterone should be used carefully in heart patients because it can cause fluid retention and changes in blood pressure. Those with heart failure, a history of stroke, or clotting problems need close medical supervision before taking it.

The use of drinks that contain alcohol raises your risk of low blood pressure from progesterone. If you drink alcohol, talk to your doctor. You may need to have your blood pressure monitored while you take this drug.

Progesterone 200 mg tablets are hormone pills that help regulate periods, protect the uterus lining, and support pregnancy. They work by preparing the womb for a baby or keeping the lining from growing too much. Common side effects include breast soreness, bloating, sleepiness, dizziness, and mood changes. Grapefruit and alcohol can interfere with the medicine, so they should be avoided. Women with breast cancer, liver problems, unexplained bleeding, blood clots, or stroke should not take it unless a doctor approves. In short, it is a supportive hormone medicine that must be used under medical guidance, because taking more than 200 mg at once can cause serious side effects like extreme drowsiness, dizziness, or even complications requiring urgent medical care.
