Precautions
Patients with pituitary adenoma; weight-related amenorrhoea until weight corrected; polycystic ovary disease or endometriotic cysts; metabolic bone disease. Monitor closely as there may be initial worsening of signs and symptoms during first few wk of therapy. Contraceptive measures to be taken to protect against unwanted ovulation in females.
Pregnancy-Lactation
Pregnancy
Based on findings in animal studies and mechanism of action, therapy can cause fetal harm when administered to a pregnant woman; expected hormonal changes that occur with treatment increase risk for pregnancy loss; in animal developmental and reproductive toxicology studies, daily administration of drug to pregnant rats during period of organogenesis caused maternal toxicity and embryo-fetal toxicities, including loss of pregnancy, at doses as low as 0.2, 0.8, and 8 times estimated human daily dose based on body surface area; advise pregnant patients and females of reproductive potential of potential risk to fetus
Based on mechanism of action, treatment may impair fertility in males of reproductive potential
Lactation
The safety and efficacy not established in females; there are no data on presence of drug in human milk, effects of drug on milk production, or on breastfed child; because of potential for serious adverse reactions in a breastfed child from treatment, a decision should be made to either discontinue breastfeeding, or discontinue drug taking into account importance of drug to mother
Interactions
Decrease in LHRH receptors in pituitary with hyperprolactinaemic drugs antagonises effects of triptorelin.

Mechanism of Action
Triptorelin is a synthetic analogue of natural gonadotropin-releasing hormone. Initial admin stimulates the release of pituitary gonadotrophins with a transient increase in testosterone levels in men and in oestradiol levels in women, leading to an initial worsening of symptoms during the first wk. Prolonged admin leads to a suppression of gonadotrophins and a decrease in plasma testosterone or oestradiol after approximately 20 days, which is maintained for as long as triptorelin is admin.
