Full Prescribing Info
Contents
Progesterone.
Description
Each 8% gel contains progesterone 90 mg/dose.
Each applicator contains 1.45 g of gel and delivers 1.125 g of gel.
Excipients/Inactive Ingredients: Glycerin, light paraffin, hydrogenated palm oil glyceride, carbopol 974P, sorbic acid, polycarbophil, sodium hydroxide and purified water.
Action
Pharmacology: The pharmacological particulars of Crinone are those of the naturally occurring progesterone with induction of a full secretory endometrium.
Pharmacokinetics: The progesterone vaginal gel is based on a polycarbophil delivery system which attaches to the vaginal mucosa and provides a prolonged release of progesterone for at least 3 days.
Toxicology: Preclinical Safety Data: In rabbits, Crinone was an eye irritant categorised as class IV (minimal effects clearing in <24 hrs), but not a dermal irritant.
A moderate vaginal irritation was found in rabbits after application of 2 mL/day of 8% gel for 5 days.
Indications/Uses
Treatment of disorders associated with progesterone deficiency eg, infertility due to inadequate luteal phase, and for use during in vitro fertilization, where infertility is mainly due to tubal, idiopathic or endometriosis linked sterility associated with normal ovulatory cycles.
Dosage/Direction for Use
Treatment of Infertility Due to Inadequate Luteal Phase: 1 application (1.125 g gel 8%) once daily, starting after documented ovulation or arbitrarily on the 18th to 21st day of the cycle.
When used during in vitro fertilization, daily application of Crinone gel 8% should be continued for 30 days if there is laboratory evidence of pregnancy.
Children: Not applicable.
The Elderly: Not applicable.
Administration: Crinone is applied directly from the specially designed sealed applicator into the vagina. Remove the applicator from the sealed wrapper. Do not remove the twist-off cap at this time.
1. Grip the applicator firmly by the thick end. Shake down like a thermometer to ensure that the contents are at the thin end.
2. Twist off the tab and discard.
3. The applicator may be inserted while the patient is in a sitting position or when lying on the back with knees bent. Gently insert the thin end of applicator well into the vaginal cavity.
4. Press the thick end of the applicator firmly to deposit gel. Remove the applicator and discard in a waste container.
5. Crinone coats the vaginal mucosa to provide long-lasting release of progesterone.
Overdosage
Not applicable.
Contraindications
Known hypersensitivity to progesterone or to any of the excipients of Crinone. Undiagnosed vaginal bleeding; known or suspected progesterone-sensitive malignant tumours and porphyria.
Use in pregnancy & lactation: In case of corpus luteum deficiency, Crinone can be used during the 1st month of pregnancy. Do not use during lactation.
Special Precautions
Caution is recommended on the use of Crinone in patients with severe hepatic insufficiency.
In cases of breakthrough bleeding, as in all cases of irregular vaginal bleeding, non-functional causes should be considered. In cases of undiagnosed vaginal bleeding, adequate diagnostic measures should be undertaken.
Crinone is not indicated in threatened abortion. Treatment should be discontinued in the event of a missed abortion.
Although risk of thromboembolism has been associated with estrogens, a link with progestins remains questionable. Therefore, in women with generally recognized risk factors for thromboembolic events eg, personal or family history, treatment with Crinone may further increase the risk. In these women, the benefits of Crinone administration need to be weighed against the risks. It should be noted, however, that pregnancy itself carries an increased risk of thromboembolic events.
Avoid concurrent use with other intravaginal preparations (see Interactions).
The excipient, sorbic acid, may cause local skin reactions (eg, contact dermatitis) or vaginal irritation.
Effects on the Ability to Drive or Operate Machinery: Drivers and users of machines are warned that risk of somnolence may occur.
Use In Pregnancy & Lactation
In case of corpus luteum deficiency, Crinone can be used during the 1st month of pregnancy. Do not use during lactation.
Adverse Reactions
Common (>1/100 to 1/10): Headache, somnolence, breast tenderness; vaginal irritation, itching or burning.
Post-Marketing Reports: In addition, intermenstrual bleeding (spotting), hypersensitivity reactions usually manifesting as skin rash, and other mild application site reactions have been reported post-marketing.
Rare events of urticaria and pruritis were noted.
Drug Interactions
Crinone is not recommended for concurrent use with other vaginal preparations.
Although there is evidence of interaction between oral progestogens and CYP3A4 inducers, resulting in a decrease of serum progestogen levels, no significant consequences on progesterone levels is expected from concurrent administration of Crinone vaginal gel with CYP3A inducers.
Incompatibilities: No incompatibilities were found with the usual contraceptive devices.
Storage
Store below 30°C.
Shelf-Life: 36 months.
ATC Classification
G03DA04 - progesterone ; Belongs to the class of pregnen (4) derivative progestogens.
