HP 500mg Injection belongs to the category of a synthetic progesterone female hormone called progestin used to prevent premature labour. Premature labour can start before 37 completed weeks of pregnancy and can be caused by premature rupture of membranes, high blood pressure during pregnancy (pre-eclampsia), and poor diet. Preterm labour symptoms include leaking fluid or bleeding from the vagina, the feeling of pressure in the pelvis, and cramps that feel like menstrual cramps regularly.

HP 500mg Injection contains 'Hydroxyprogesterone', a progestin (female hormones) that modulates the immune response of pregnant women to prevent rejection of the embryo and allow its attachment to the uterus. HP 500mg Injection prevents miscarriage and helps lower the risk of premature birth in pregnant women who have had past premature labour. HP 500mg Injection should be administered only to those pregnant women who are pregnant with one baby or who have had a preterm (premature) delivery of one baby in the past.

HP 500mg Injection will be administered by a healthcare professional. Do not self-administer. In some cases, you may experience certain common side effects such as nausea, vomiting, itching, hives (skin rashes), swelling in the face, lips, tongue, or throat, and diarrhoea. Not everybody experiences these side effects. Most of the side effects of HP 500mg Injection do not require medical attention and gradually resolve over time. Talk to your doctor if you feel any discomfort while taking HP 500mg Injection.

Preterm labour: Preterm labour, also called premature labour, is when your baby starts getting ready for birth too early in your pregnancy. It can start before 37 completed weeks of pregnancy. Premature labour can be caused by premature rupture of membranes, high blood pressure during pregnancy (pre-eclampsia), and poor diet. Symptoms of preterm labour include leaking fluid or bleeding from the vagina, the feeling of pressure in the pelvis, and cramps that feel like menstrual cramps regularly. Few premature babies need special care and also have long-term mental and physical disabilities.
