Susten SR 300 mg Tablet – Uses, Dosage, Side Effects & Price
Susten SR 300 mg is a slow-release progesterone tablet that provides the body with a steady supply of an important female hormone. Each tablet contains 300 mg of natural, micronized Progesterone, matching the hormone the ovaries make naturally. Because it's micronized, the particles are very fine, so the body absorbs them better than standard Progesterone.
This mid-range strength is often prescribed for women who need reliable hormone support but not the highest dose. Gynecologists and fertility specialists use it to help maintain early pregnancy, reduce the risk of premature delivery, and support the uterine lining after fertility treatments. It's also used to correct cycle problems caused by low Progesterone, such as irregular periods or abnormal bleeding. The extended-release design means one tablet a day usually covers a full 24 hours, making the routine easy to follow.
Working mechanism of Progesterone
In a natural menstrual cycle, the ovary releases progesterone after ovulation. Its job is to tell the uterus to get ready for a possible pregnancy. Susten SR 300 mg copies this signal. Once absorbed, Progesterone attaches to receptors in the uterine tissue. The endometrium becomes richer in blood vessels and glands, creating a soft, supportive bed where an embryo can attach. If conception happens, Progesterone keeps sending this "hold steady" message so the lining isn't shed as a period.
The hormone also calms the uterus's smooth muscle and lowers its sensitivity to oxytocin, the hormone that drives contractions. This helps prevent the uterus from contracting too early. Progesterone also supports cervical strength, which is one reason it's used to lower the risk of premature birth. The sustained-release matrix lets small amounts of Progesterone into the blood over time, so levels stay even and side effects are often milder than with fast-release forms.

Precautions with Progesterone
Progesterone therapy isn't right for everyone. Tell your doctor before starting if any of the following apply to you:
- A personal or family history of blood-clotting disorders, deep vein thrombosis, or pulmonary embolism
- Known or suspected hormone-sensitive cancers, such as breast or uterine cancer
- Active liver disease or abnormal liver function tests
- Unexplained bleeding from the vagina
- Porphyria, a rare inherited blood disorder
- Sensitivity to Progesterone or to peanut or soy products, if the formulation contains them (check the label)
Women with diabetes should check their blood sugar more often, since Progesterone can slightly lower insulin sensitivity. If you have a history of depression, watch for mood changes and report them early. Conditions that get worse with fluid retention, such as asthma, epilepsy, migraine, and heart or kidney disease, also need closer monitoring. Dizziness and sleepiness are possible; be careful when driving or doing tasks that need full attention. Limit alcohol during treatment. Certain drugs can raise or lower progesterone levels, including antifungals, some antibiotics, seizure medicines, and herbal remedies. Share your complete medicine list with your doctor or pharmacist.

Usage instructions of Progesterone - Susten SR 300 mg
- Follow your doctor's prescription for dose and duration. Most patients take one tablet a day.
- Take the tablet whole with water. Breaking or chewing it destroys the slow-release mechanism.
- Choose a fixed time each day. Evening dosing is popular because any drowsiness then happens while you sleep.
- Food doesn't block absorption much, but taking it the same way every day (always with a meal or always without) keeps results consistent.
- If you forget a dose, take it when you remember, unless your next dose is almost due. In that case, skip the missed one and continue as normal.
- Keep taking it for the full time your doctor recommends, even if you feel fine. Pregnancy support often continues until a specific week.
- Store the tablets at room temperature, away from moisture, heat, and children.
