Dosage Intravaginal administration Cervidil = Intracervical gel Prostin E2 = Intravaginal suppository
The dosage of dinoprostone in the vaginal insert is 10 mg designed to be released at approximately 0.3 mg/hour over a 12 hour period. Cervidil should be removed upon onset of active labor or 12 hours after insertion.
Classification Uterine Stimulants, Abortifacient, ProstaglandinAction Prostaglandin E2
Uterine and gastrointestinal smooth muscle stimulation
Cervical softening and dilation Increases frequency and strength of uterine
contraction.Indication Cervidil Vaginal Insert (dinoprostone, 10 mg) is
indicated for the initiation and/or continuation of cervical ripening in patients at or near term in whom there is a medical or obstetrical indication for the induction of labor.
Contraindication Endocervically administered dinoprostone gel is not recommended for the following:
Patients in whom oxytocic drugs are generally contraindicated or where prolonged contractions of the uterus are considered inappropriate, such as:o Cases with a history of cesarean section or
major uterine surgery.o Cases in which cephalopelvic
disproportion is present.o Cases in which there is a history of
difficult labor and/or traumatic delivery.o Grand multiparae with 6 or more previous
term pregnancies cases with non-vertex presentation.
o Cases with hyperactive or hypertonic uterine patterns.
o Cases of fetal distress where delivery is not imminent.
o In obstetric emergencies where the benefit-to-risk ratio for either the fetus or the mother favors surgical intervention.
Patients with hypersensitivity to prostaglandins or constituents of the gel.
Patients with placenta previa or unexplained vaginal bleeding during this pregnancy.
Patients for whom vaginal delivery is not indicated, such as vasa previa or active herpes genitalia.
Vaginal Suppository Hypersensitivity to dinoprostone. Acute pelvic inflammatory disease. Patients with active cardiac, pulmonary, renal,
or hepatic disease.Adverse Reaction Nausea and vomiting; diarrhea
Fever Orthostatic hypotension Arrhythmia
Nursing Responsibilities Store suppositories in freezer and bring to room temperature before insertion.
Store cervical gel in freezer and bring to room temperature in room temperature, just prior to use. Do not force warming with external sources (ie, water bath, microwave)
Ensure adequate hydration throughout the procedure.
Monitor uterine tone and vaginal discharge throughout the procedure and several days after procedure.
Be prepared to support patient through labor (cervical ripening). Give oxytocin 6-12 hours after dinoprostone.

Trade Name Hemostan, Fibrinon, Cyklokapron, Lysteda, Transamin
Generic Name Tranexamic AcidDosage
Classification Anti-fibrinolytic, antihemorrhagicAction
Tranexamic acid is a synthetic derivative of the amino acid lysine. It exerts its antifibrinolytic effect through the reversible blockade of lysine-binding sites on plasminogen molecules. Anti-fibrinolytic drug inhibits endometrial plasminogen activator and thus prevents fibrinolysis and the breakdown of blood clots. The plasminogen-plasmin enzyme system is known to cause coagulation defects through lytic activity on fibrinogen, fibrin and other clotting factors. By inhibiting the action of plasmin (finronolysin) the anti-fibrinolytic agents reduce excessive breakdown of fibrin and effect physiological hemostasis.
Indication Tranexamic acid is used for the prompt and effective control of hemorrhage in various surgical and clinical areas:
Treating heavy menstrual bleeding Hemorrhage following dental and/or oral
surgery in patients with hemophilia Management of hemophilic patients (those
having Factor VIII or Factor IX deficiency) who have oral mucosal bleeding, or are undergoing tooth extraction orother oral surgical procedures.
Obstetrical and gynecological: abortion, post-partum hemorrhage and menometrorrahgia.
Contraindication Allergic reaction to the drug or hypersensitivity Presence of blood clots (eg, in the leg, lung,
eye, brain), have a historyof blood clots, or are
at risk for blood clots Current administration of factor IX complex
concentrates or anti-inhibitorcoagulant concentrates
Adverse Reaction Severe allergic reactions such as rash, hives, itching, dyspnea, tightnessin the chest, swelling of the mouth, face, lips or tongue* Calf pain, swelling or tenderness* Chest pain* Confusion* Coughing up blood* Decreased urination* Severe or persistent headache* Severe or persistent body malaise* Shortness of breath* Slurred speech* Slurred speech* Vision changes
Nursing Responsibilities Unusual change in bleeding pattern should be immediately reported to the physician.
For women who are taking Tranexamic acid to control heavy bleeding, the medication should only be taken during the menstrual period.
Tranexamic Acid should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.
The medication can be taken with or without meals.
Swallow Tranexamic Acid whole with plenty of liquids. Do not break, crush,or chew before swallowing.
If you miss a dose of Tranexamic Acid, take it when you remember, then take your next dose at least 6 hours later. Do not take 2 doses at once.
