Susten 400 mg Soft Gelatin Capsule

Susten 400 mg Soft Gelatin Capsule is a progesterone medicine used as part of infertility therapy and other doctor-directed hormone support needs. Each capsule contains 400 mg of progesterone, a natural female hormone. It belongs to the progestogen class and is commonly prescribed to support the uterine lining, help with progesterone deficiency, and assist in selected fertility or pregnancy-support situations. Susten 400 mg Soft Gelatin Capsule should be used only when a clinician has determined that this higher-strength capsule is appropriate.

How it works: Progesterone helps prepare and maintain the lining of the uterus so it can support implantation and early pregnancy when that is the treatment goal. In a soft gelatin capsule, the medicine is swallowed and absorbed through the digestive tract to raise progesterone levels in the body. It also helps balance estrogen’s effects on the uterus, which is why Susten 400 mg Soft Gelatin Capsule may be used in hormone support plans directed by a doctor.

Susten 400 mg Soft Gelatin Capsule is a higher-strength option compared with Susten 300 mg Soft Gelatin Capsule, so it may be chosen when a doctor wants a larger amount of progesterone in fewer capsules. This can be helpful for people who need a stronger hormone supplement or a simpler capsule schedule, but it is not a starting dose for everyone. The 400 mg soft gelatin capsule is meant for patients specifically assessed by a clinician, since the right progesterone dose depends on the treatment goal and response.

• Progesterone supplementation
• Infertility therapy support
• Luteal phase support

• Swallow Susten 400 mg Soft Gelatin Capsule whole with water unless your doctor gives different instructions.

Each Susten 400 mg Soft Gelatin Capsule provides 400 mg of progesterone. The number of capsules you take and how often you take them may vary by condition, but it is only used in a doctor-selected regimen and should not be adjusted on your own. Your clinician decides the exact schedule, and the daily maximum depends on the treatment plan and your response to therapy.

Do not change your dose or stop the medicine without speaking to your doctor.
