CRINONE

CRINONE is prescribed to women with luteal phase defect to supplement progesterone. It is also used in Assisted Reproductive Technology procedures, such as IVF, to supplement or replace natural progesterone. Your doctor may have prescribed CRINONE for a different reason.

The use of Crinone 8% vaginal progesterone gel resulted in a lower implantation rate compared to the use of IM progesterone-in-oil.

According to this study, the use of progesterone was found to decrease the occurrence of miscarriages. However, the reduction in miscarriages was only observed in individuals who had previously experienced a miscarriage. The study also revealed that the greatest impact of progesterone was seen in women who had a history of three or more miscarriages.

Potential Risks of Crinone® on Fetal Development:
There have been reports of birth defects in babies whose mothers used Crinone® during the early stages of pregnancy. These defects include an abdominal wall defect and a cleft palate. However, it is important to note that a definitive link between Crinone® and these birth defects has not been established. Further research is needed to confirm or refute any causal association.

In terms of live birth rates, cycles using Crinone gel showed similar results compared to cycles using IMP (RR 0.91; 95% CI 0.73-1.13). There were also no significant differences in biochemical pregnancy rates (RR 1.12, 95% CI 0.65-1.92), spontaneous abortion rates (RR 1.41, 95% CI 0.90-2.20), and clinical pregnancy rates (RR 1.00, 95% CI 0.86-1.17) between the two groups.

Once tests confirm your pregnancy, you may be advised to continue using Crinone to support your pregnancy for a duration of 30 days. The applicator is specifically designed to deliver an accurate amount of gel (1.125 g, containing 90 mg progesterone).

It is normal and harmless to experience some gel residue buildup. If desired, you can manually remove the leftover gel by gently inserting your finger into the vagina and clearing it.

There were no significant differences in the rates of biochemical pregnancy, miscarriage, or ectopics regardless of age. However, in younger patients undergoing IVF, the use of Crinone for luteal phase support resulted in significantly higher pregnancy rates compared to IMP.

Progesterone supplementation is employed in numerous assisted reproductive technology (ART) techniques to enhance the receptiveness of the endometrium.

You may experience symptoms such as bloating, cramps, stomach pain, constipation, diarrhea, nausea, breast swelling/pain, pain around the vaginal area, drowsiness, tiredness, decreased interest in sex, joint pain, or headache. If any of these symptoms persist or worsen, please inform your doctor or pharmacist immediately.

Please inform your healthcare provider if you have a history of fluid build-up or swelling before starting Crinone (progesterone). If you experience unexplained swelling, rapid weight gain (more than 3 pounds in a day or 5 pounds in a week), or sudden difficulty breathing, contact your healthcare provider immediately or seek medical assistance.

Crinone is a medication designed for vaginal use that is prescribed to women who are not experiencing menstrual periods due to a deficiency of progesterone in their bodies. Its purpose is to induce menstrual periods in women who have not yet entered menopause.

It is understood that progesterone plays a role in stimulating the production of GABA, a neurotransmitter that aids in sleep. However, GABA also has the ability to enhance mood, promoting feelings of relaxation and well-being. When progesterone levels decrease, so do GABA levels. Consequently, low progesterone levels can contribute to symptoms such as anxiety, sadness, or depression.

Usually, the gel remains on the vaginal walls for a few days while the progesterone is absorbed. If you notice small, white globules as a discharge after several days of use, there is no need to worry. It is normal and harmless to have some buildup of gel residue.

As a result, there is no need to continue lying down after using CRINONE. If you experience discomfort from gel accumulation, consult your doctor. Take the applicator out of the sealed wrapper.

Progesterone production is primarily carried out by the ovary until the placenta assumes this role at approximately 8-10 weeks of gestational age. To err on the side of caution, most IVF clinics in the United States advise progesterone supplementation for 8-10 weeks following egg retrieval or frozen embryo transfer (FET).

The absorption half-life of Crinone is approximately 25-50 hours, while the elimination half-life is only 5-20 minutes. This means that the rate at which Crinone is absorbed is the limiting factor in its pharmacokinetics, rather than its elimination.

It is important to use Crinone at the same time every day. If you are using it twice a day, one applicator should be used in the morning and another one at night. You can find detailed instructions on how to use the applicator inside the carton.

CRINONE should be stored at a temperature between 20°C and 25°C (68°F and 77°F). It is important to avoid exposing CRINONE to extreme cold or heat. There is no need to refrigerate CRINONE or take any other special precautions. The individually wrapped applicators are convenient to carry in a handbag for use when you are not at home.

Crinone, a prescription medication utilized in Assisted Reproductive Technology, does not currently have a generic alternative. The typical price for a 6, 1.125GM of 4% Tube of Crinone is approximately $134.05.

Possible side effects that you should promptly inform your healthcare provider about include allergic reactions such as skin rash, itching, hives, and swelling of the face, lips, tongue, or throat. Additionally, you should report any symptoms of a blood clot, such as pain, swelling, or warmth in the leg, as well as shortness of breath and chest pain.

According to a prospective, randomized study published in Fertil Steril in 2010, Crin-one vaginal gel is just as effective and better tolerated than intramuscular progesterone for luteal phase support in in vitro fertilization-embryo transfer cycles.

Progesterone supplementation is typically recommended by most IVF clinics in the US for a period of 8-10 weeks following egg retrieval or frozen embryo transfer (FET), taking into account the estimated timing and a conservative approach.

Crinone (progesterone) is a long-acting vaginal gel used in fertility treatments and to restart menstrual periods. It is only available as a brand medication, making it potentially very costly.

A Prospective, Randomized Study Shows Progesterone Gel (Crinone®8%) is More Comfortable Than Progesterone Suppositories (Utrogest®) for Luteal Phase Support and Yields Similar Pregnancy Rates.

Previously, research findings were divided on whether vaginal progesterone or intra-muscular progesterone was more effective. However, current consensus suggests that there is no significant difference in pregnancy rates between the two methods. As a result, the majority of women now tend to favor using vaginal progesterone.

Conclusion: The use of Crinone 8% vaginal progesterone gel for luteal phase support after IVF-ET results in reduced implantation efficiency, as evidenced by lower embryonic implantation rates and higher biochemical pregnancy rates compared to the use of IM progesterone-in-oil.

The average serum progesterone level at the time of endometrial biopsy was 11.3 ± 6.5 ng/mL for cycles treated with Crinone and 65.2 ± 12.5 ng/mL for cycles treated with IM progesterone.

Based on the conclusion, it can be inferred that Crinone 8% administered once daily is an effective alternative to IM progesterone for women who need complete progesterone replacement. It produces similar endometrial development and pregnancy rates without causing early bleeding.

Regardless of the type of progesterone used, the implantation rates were approximately 46 percent. The clinical pregnancy rates were approximately 62 percent with the shot and approximately 61 percent with the gel. The live birth rates were approximately 50 percent with the shot and approximately 49 percent with the gel.

Having some gel residue build-up is a common occurrence and is not harmful. If the gel is applied in the morning, there is a lower chance of gel accumulation because activities like walking can help spread the gel on the vaginal walls. As a result, it is not necessary to stay lying down after using CRINONE.

Crinone® has sustained release properties that result in prolonged absorption of progesterone. The absorption half-life of Crinone® is approximately 25-50 hours, while the elimination half-life is only 5-20 minutes. This means that the rate at which Crinone® is absorbed into the body is the limiting factor in its pharmacokinetics, rather than the rate at which it is eliminated.

As a component of ART treatment, CRINONE aids in the preparation of the uterine lining to ensure its readiness for receiving and nurturing an embryo. Survey findings indicate that women attempting to conceive expressed a preference for CRINONE over vaginal capsules or injectable alternatives.
