Undesirable reactions in men
Undesired reactions with triptorelin are associated with its expected pharmacological effects: initial increase in testosterone concentration, and then almost complete suppression of testosterone synthesis.
The frequency of adverse reactions that may occur during therapy is given in the following gradation: very often (> 1/10), often (> 1/100, <1/10), infrequently (> 1/1000, <1/100), rarely (> 1/10000, <1/1000), very rarely (<1/10000) and the frequency is unknown (the frequency can not be determined based on the available data).

Disturbances from the skin and subcutaneous tissues: very often - hyperhidrosis; infrequently - hypotrichosis; rarely - alopecia, acne, itching, rash; very rarely blisters; frequency unknown - Quincke's edema, hives, purpura.
Disturbances from musculoskeletal and connective tissue: very often - back pain; often - pain in the limbs; rarely - muscle spasm, muscle weakness, myalgia, arthralgia; very rarely - swelling of joints, stiffness of muscles and joints, osteoarthritis; frequency unknown - musculoskeletal pain, joint stiffness, bone pain.

General disorders and disorders at the site of administration: very often - asthenia; often - fatigue, reaction at the injection site, pain at the injection site, redness at the injection site, inflammation at the injection site, swelling, irritability; rarely - pain; very rarely - fever, flu-like syndrome; the frequency is unknown - a feeling of discomfort, chest pain, malaise.
Laboratory and instrumental data: infrequently - increased activity of lactate dehydrogenase, gamma-glutamyltransferase, weight loss; rarely - increased activity of alanine aminotransferase, aspartate aminotransferase, weight gain, increased creatinine concentration, urea in blood plasma; very rarely - increased activity of alkaline phosphatase in blood plasma, hyperthermia; frequency unknown - increased blood pressure.
Triptorelin causes a short-term increase in the concentration of circulating testosterone during the first week after the first injection of the drug.In this regard, there may be a temporary worsening of symptoms of prostate cancer, which is usually manifested by disorders of the urinary tract, increased pain associated with metastatic damage. These symptoms are transient and usually disappear after 1-2 weeks.
In isolated cases, obstruction of the urinary tract or metastatic compression of the spinal cord is noted. As a consequence, patients with metastatic spinal cord lesions and / or obstruction of the upper or lower urinary tract should be monitored more closely within the first few weeks after initiation of therapy. The use of GnRH agonists for the treatment of prostate cancer may be associated with an increased risk of bone loss, the development of osteoporosis and an increased risk of bone fractures.
Patients receiving long-term therapy with GnRH analogues in combination with radiotherapy may experience more unwanted reactions, especially from the gastrointestinal tract, which are associated with the course of radiation therapy.
Undesirable reactions in women
As a consequence of the decrease in estrogen concentration, the most frequent adverse reactions can be: headache, decreased libido, sleep disturbance, mood changes, dyspareunia, dysmenorrhea, vaginal bleeding, ovarian hyperstimulation syndrome, ovarian enlargement, pelvic pain, abdominal pain, dryness mucous membrane of the vagina and vulva, increased sweating, "hot flashes" and asthenia.

At the beginning of treatment during a period of short-term increase in the concentration of estradiol in the blood plasma, the symptoms of endometriosis, including pain in the pelvic region and dysmenorrhea, can be exacerbated. These symptoms are transient and, as a rule, disappear after 1-2 weeks. Uterine bleeding, including menorrhagia, metrorrhagia may occur within one month after the first injection. There may be an increase in the size of the ovaries, pain in the pelvic region and / or pain in the abdominal region.
