Gestone 100 Injection (Progesterone)

Introduction About Gestone 100 Injection (Progesterone)

Gestone 100 Injection (Progesterone) is a prescription progesterone injection used when the body needs extra progesterone support. Progesterone is a natural hormone that helps prepare and maintain the lining of the uterus.

When progesterone levels are not within the normal range, a clinician may recommend progesterone supplementation in specific situations, especially in fertility and reproductive care.

What Gestone 100 Injection is commonly used for

Your clinician may prescribe progesterone injections for several reasons, depending on your history and current treatment plan. Common uses include:

• Luteal phase support in fertility treatment (for example, IVF or other assisted reproductive care), where progesterone helps support the uterine lining after ovulation or embryo transfer.
• Support in early pregnancy in selected cases, when a clinician believes progesterone supplementation may help based on symptoms and medical history.
• Hormone therapy support with estrogen in certain patients who have a uterus, since progesterone is often used to help protect the uterine lining when estrogen is given.

Your exact reason and schedule should be determined by your prescriber, since progesterone needs can vary from person to person.

How it works

Gestone 100 Injection contains progesterone, which signals the uterus to maintain a lining that can support implantation and early pregnancy. In hormone therapy settings, progesterone helps balance estrogen’s effect on the uterine lining.

How it is given

Gestone 100 Injection is typically given as an intramuscular (IM) injection, which means it is injected into a muscle. Many progesterone injections are oil-based, which can make the shot feel sore afterward. Some people are taught to inject at home, while others receive it in a clinic.

Because dosing depends on your treatment plan, do not change the dose or schedule on your own. If a dose is missed, contact your clinic or prescriber for the safest next step. Doubling up without guidance is not a good idea.

What you may feel after the injection

Some effects are common and not usually dangerous, especially early on:

• Injection site pain, swelling, warmth, or a firm lump
• Tiredness or sleepiness
• Headache
• Breast tenderness
• Bloating or mild stomach discomfort
• Mood changes

Call a clinician urgently if you notice symptoms that could signal a serious reaction, such as:

• Signs of a severe allergy (trouble breathing, facial swelling, widespread rash)
• Possible blood clot symptoms (sudden chest pain, shortness of breath, swelling or pain in one leg)
• Severe headache, vision changes, or weakness on one side
• Yellowing of the skin or eyes (possible liver issue)

Serious side effects are not expected for most people, but they are important to recognize early.

Precautions to discuss before using progesterone injections

Before starting Gestone 100 Injection, your prescriber will usually want to know if you have a history of:

• Blood clots, stroke, or clotting disorders
• Breast cancer or certain hormone-sensitive cancers
• Liver disease
• Unexplained vaginal bleeding
• Allergies to progesterone or to ingredients used in the injection base (many progesterone injections use an oil base, so checking the product label matters)

Also share a full medication list. Some medicines and supplements can affect hormone levels. If you are taking seizure medicines or certain antibiotics, or using herbal products, it is worth a quick check for interactions.

Available strengths

Gestone 100 is one strength option. Progesterone injections may also be available in other strengths, depending on the manufacturer and supply chain. In many markets, progesterone injections are commonly seen in strengths such as 50 mg, 100 mg, or 200 mg. The exact concentration (mg/mL) and vial size may vary, so it is smart to confirm the label and follow the prescribed dose exactly.

Substitutes and alternatives

If Gestone 100 Injection is not the right fit, clinicians sometimes consider other progesterone options. These are not always interchangeable dose-for-dose, so changes should be clinician-led.

Possible alternatives your prescriber may discuss include:

• Generic progesterone injection
• Susten 100 mg Injection (Progesterone)
• Susten 200 mg Injection (Progesterone)
• Susten 8% Vaginal gel (Progesterone)
• Susten 400 mg (Progesterone)
• Vaginal progesterone options (commonly used in fertility care), such as progesterone gel or inserts (brand examples on the market include Crinone and Endometrin)
• Oral micronized progesterone (a capsule form; a known brand is Prometrium)
• Hydroxyprogesterone caproate injections (a different progesterone-like medicine, used for different clinical reasons and not a direct swap)

Which option is best often depends on your diagnosis, treatment goals, tolerance of side effects, cost, and how your body responds.

FAQs

1. Will Gestone 100 Injection affect a pregnancy test result?

Progesterone typically does not create a false positive on a pregnancy test. False positives are more often linked to certain fertility trigger shots that contain hCG. If you are unsure, ask your clinic which test timing they recommend.

2. Can I drink alcohol while using progesterone injections?

It is best to ask your prescriber. Alcohol can worsen sleepiness, dizziness, and mood changes for some people. If you drink, keeping it minimal and watching how you feel is a common approach, unless your clinician advises avoiding it.

3. Does progesterone injection cause weight gain?

Some people notice fluid retention or bloating that can look like weight gain. True long-term weight gain is not guaranteed and varies by individual, dose, and duration. Track changes and discuss them if they feel significant.

4. How long does progesterone from an injection stay in the body?

It depends on the formulation (often oil-based), dose, and your metabolism. Some progesterone injections are designed to last longer than oral forms. Your clinician can explain what to expect for your exact product and schedule.

5. Can I use Gestone 100 Injection while breastfeeding?

This depends on your medical situation and why progesterone is being used. Safety can vary by timing postpartum and dose. Your prescriber or pediatrician should guide you based on your specific case.
