Drug (Route; Brand Name)Adverse Reactions / EffectsNotes and References
Levonorgestrel-releasing intrauterine system (LNG-IUS; Mirena®)Warnings and Precautions:
  • If pregnancy should occur with Mirena in place, remove Mirena.
  • There is increased risk of ectopic pregnancy including loss of fertility, pregnancy loss, septic abortion (including septicemia, shock and death) and premature labor and delivery.
  • Group A streptococcal infection has been reported; strict aseptic technique is essential during insertion.
  • Before using Mirena, consider the risks of pelvic inflammatory disease (PID).
  • Bleeding patterns become altered, may remain irregular and amenorrhea may ensue.
  • Perforation may occur during insertion. Risk is increased in women with fixed retroverted uteri, during lactation, and postpartum.
  • Embedment in the myometrium and partial or complete expulsion may occur.
  • Persistent enlarged ovarian follicles should be evaluated.
Serious:
  • Ectopic pregnancy - Incidence in clinical trials excluding women with risk factors for ectopic was 0.1% per year.
  • Intrauterine pregnancy - “As of September 2006, 390 live births out of an estimated 9.9 million Mirena users had been reported.”
  • Group A streptococcal sepsis (GAS) – “As of September 2006, 9 cases of Group A streptococcal sepsis (GAS) out of an estimated 9.9 million Mirena users had been reported.”
  • Pelvic Inflammatory Disease
  • Embedment
  • Perforation
  • Breast cancer – “Spontaneous reports of breast cancer have been received during postmarketing experience with Mirena… Two observational studies have not provided evidence of an increased risk of breast cancer during the use of Mirena.”

“The data provided reflect the experience with the use of Mirena in the adequate and well-controlled studies for contraception (n=2,339) and heavy menstrual bleeding (n=80). For the contraception indication, Mirena was compared to a copper IUD (n=1,855), to another formulation of levonorgestrel intrauterine system (n=390) and to a combined oral contraceptive (n=94) in women 18 to 35 years old. The data cover more than 92,000 woman-months of exposure. For the treatment of heavy menstrual bleeding indication (n=80), the subjects included women aged 26 to 50 with confirmed heavy bleeding and exposed for a median of 183 treatment days of Mirena (range 7 to 295 days). The frequencies of reported adverse drug reactions represent crude incidences. The adverse reactions seen across the 2 indications overlapped, and are reported using the frequencies from the contraception studies.”

Contraceptive vaginal ring (NuvaRing®)Warning:
Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive use. This risk increases with age, particularly in women over 35 years of age and with the number of cigarettes smoked. For this reason, COCs should not be used by women who are over 35 years of age and smoke.

Most common (reported by 5-14% of women in clinical trials:
  • Vaginitis
  • Headache
  • Upper respiratory infection
  • Vaginal secretion
  • Sinusitis
  • Weight gain
  • Nausea
Adverse events leading to discontinuation in 1-2.5% of women using NuvaRing in trials:
  • Device-related events (foreign body sensation, coital problems, device explusion)
  • Vaginal symptoms (discomfort/vaginitis/vaginal secretion)
  • Headache
  • Emotional lability
  • Weight gain
Also any adverse reactions that are associated with the use of combination hormonal contraceptives are also likely to apply to combination vaginal hormonal contraceptives, such as NuvaRing.
NuvaRing [package insert]. Whitehouse Station, NJ: Merck & Co; 2012.
Tranexamic acid (oral; Lysteda®)Warnings and Precautions:
  • The risk of thrombotic and thromboembolic events may increase further when hormonal contraceptives are administered with Lysteda, especially in women who are obese or smoke cigarettes. Women using hormonal contraception should use Lysteda only if there is a strong medical need and the benefit of treatment will outweigh the potential increased risk of a thrombotic event. Do not use Lysteda in women who are taking more than the approved dose of a hormonal contraceptive.
  • Concomitant use of Lysteda with Factor IX complex concentrates, anti-inhibitor coagulant concentrates, or all-trans retinoic acid (oral tretinoin) may increase the risk of thrombosis.
  • Visual or ocular adverse effects may occur with Lysteda. Immediately discontinue use if visual or ocular symptoms occur.
  • Cerebral edema and cerebral infarction may be caused by use of Lysteda in women with subarachnoid hemorrhage.
  • Ligneous conjunctivitis has been reported in patients taking tranexamic acid.

Postmarketing reports in patients receiving tranexamic acid for various indications:
  • Nausea, vomiting, and diarrhea
  • Allergic skin reactions
  • Anaphylactic shock and anaphylactoid reactions
  • Thrombotic events (e.g., deep vein thrombosis, pulmonary embolism, cerebral thrombosis, acute renal cortical necrosis, and central retinal artery and vein obstruction) – including venous and arterial thrombotic events in women who have used Lysteda concomitantly with combined hormonal contraceptives
  • Impaired color vision and other visual disturbances
  • Dizziness
“Lysteda safety derived from two randomized, double-blind, placebo-controlled studies on treatment of heavy menstrual bleeding. Long-term safety was studied in two open label studies.”
“In one study, subjects with physician-diagnosed heavy menstrual bleeding (not using the alkaline hematin methodology) were treated with 3900 mg/day for up to 5 days during each menstrual period for up to 27 menstrual cycles. A total of 781 subjects were enrolled and 239 completed the study through 27 menstrual cycles. A total of 12.4% of the subjects withdrew due to adverse events. Women using hormonal contraception were excluded from the study… A long-term open-label extension study of subjects from the two short-term efficacy studies was also conducted in which subjects were treated with 3900 mg/day for up to 5 days during each menstrual period for up to 9 menstrual cycles. A total of 288 subjects were enrolled and 196 subjects completed the study through 9 menstrual cycles. A total of 2.1% of the subjects withdrew due to adverse events… The types and severity of adverse events in these two long-term open-label trials were similar to those observed in the double-blind, placebo-controlled studies although the percentage of subjects reporting them was greater in the 27-month study, most likely because of the longer study duration.”

0.03 mg ethinyl estradiol and 0.15 mg levonorgestrel (oral; Nordette-28®, others)Warning:
Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptives (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked.

“The relative risk of heart attack for current oral contraceptive users has been estimated to be two to six. The risk is very low under the age of 30.”

“Case control studies have found the relative risk of users compared to non-users to be 3 for the first episode of superficial venous thrombosis, 4 to 11 for deep-vein thrombosis or pulmonary embolism, and 1.5 to 6 for women with predisposing conditions for venous thromboembolic disease. Cohort studies have shown the relative risk to be somewhat lower, about 3 for new cases and about 4.5 for new cases requiring hospitalization. The approximate incidence of deep-vein thrombosis and pulmonary embolism in users of low dose (<50μg ethinyl estradiol) combination oral contraceptives is up to 4 per 10,000 woman-years compared to 0.5 to 3 per 10,000 woman-years for non-users. However, the incidence is substantially less than that associated with pregnancy (6 per 10,000 woman-years). The risk of thromboembolic disease due to oral contraceptives is not related to length of use and disappears after pill use is stopped.”

“In a large study, the relative risk of thrombotic strokes has been shown to range from 3 for normotensive users to 14 for users with severe hypertension. The relative risk of hemorrhagic stroke is reported to be 1.2 for nonsmokers who used oral contraceptives, 2.6 for smokers who did not use oral contraceptives, 7.6 for smokers who used oral contraceptives, 1.8 for normotensive users, and 25.7 for users with severe hypertension. The attributable risk is also greater in older women.”

NOTE: marketing discontinued in US; labels are not available.
As for progestogens in general.

Porphyria
  • The Drug Database for Acute Porphyria, compiled by the Norwegian Porphyria Centre (NAPOS) and the Porphyria Centre Sweden, classifies dydrogesterone as porphyrinogenic; it should be prescribed only for compelling reasons and precautions should be taken in all patients. (The Drug Database for Acute Porphyria. Available at: http://www​.drugs-porphyria.org (accessed 04/10/11))
Pregnancy
  • Anomalies (non-virilising) of the genito-urinary tract were found in a 4-month-old baby whose mother had taken dydrogesterone 20 mg daily from the eighth to twentieth week of pregnancy and 10 mg daily from then until term.1 She had also been given hydroxyprogesterone caproate 250 mg by intramuscular injection weekly from the eighth to the twentieth week.

Medroxyprogesterone acetate (injectable; Depo-Provera CI®, others)Warnings:
  • Intrauterine exposure: “Several reports suggest an association between intrauterine exposure to progestational drugs in the first trimester of pregnancy and genital abnormalities in male and female fetuses. The risk of hypospadias (5 to 8 per 1,000 male births in the general population) may be approximately doubled with exposure to these drugs. There are insufficient data to quantify the risk to exposed female fetuses, but insofar as some of these drugs induce mild virilization of the external genitalia of the female fetus, and because of the increased association of hypospadias in the male fetus, it is prudent to avoid the use of these drugs during the first trimester of pregnancy.”

N-acetyl-cysteineWarning:
After proper administration of acetylcysteine, an increased volume of liquified bronchial secretions may occur. When cough is inadequate, the open airway must be maintained by mechanical suction if necessary. When there is a mechanical block due to foreign body or local accumulation, the airway should be cleared by endotracheal aspiration, with or without bronchoscopy. Asthmatics under treatment with acetylcysteine should be watched carefully. Most patients with bronchospasm are quickly relieved by the use of a bronchodilator given by nebulization. If bronchospasm progresses, this medication should be discontinued immediately.

Adverse reactions from intravenous include:
  • Tachycardia not otherwise specified
  • Nausea
  • Vomiting not otherwise specified
  • Anaphylactoid reaction
  • Pharyngitis
  • Rhinorrhea
