Clomigen
Clomigen Uses, Dosage, Side Effects, Food Interaction and all others data.
Clomiphene citrate is the first non-steroidal preparation (a mixture of 2 geometric isomers-Cis [Zuclomiphene] & Trans [Enclomiphene]) that in many patients induces ovulation, which has failed previously. Clomiphene citrate stimulates the increased secretion of both gonadotropins (FSH & LH) from pituitary, which induce maturation of the ovarian follicle, ovulation & subsequent normal function of the corpus luteum. It does not interfere with the other functions of pituitary & thyroid & has no progesteronic or androgenic effect. Clomiphene citrate is taken orally & readily absorbed from gastro intestinal tract. Its biological half-life in plasma is 5-7 days. It is partially metabolized in the liver & through the bile is excreted in the faeces. A part is reabsorbed & enters into enterohepatic recirculation-pool.

Dosage
Clomigen dosage
For the treatment of ovulatory failure: 50 mg (1 tab) daily for 5 days, starting within about 5 days of onset of menstruation (or may be from the 1st day of menstruation). If this dose induces ovulation there is no need to increase the dose in the following courses. If this dose induces ovulation but not pregnancy, stimulation with Clomiphene citrate is to be continued up to 6 stimulative courses. If the1st course does not induce ovulation, 2nd dose of Clomiphene citrate is100 mg (2 tab at a time) daily for 5 days is recommended. Minimum 3 & maximum 6 simulative courses should constitute an adequate therapeutic trial. However, if menstrual bleeding does not occur, the patient should be examined carefully for the possible pregnancy & the next course should be delayed until correct diagnosis has been determined. The modern studies reveal that ultrasonographic monitoring for ovulation is most preferable.
