Tri-Sprintec® (norgestimate and ethinyl estradiol tablets USP) is a combination oral contraceptive containing the progestational compound norgestimate, USP and the estrogenic compound ethinyl estradiol, USP.It is used to prevent pregnancy.
It is used to treat pimples (acne).
It may be given to you for other reasons. Talk with the doctor.
Use Tri-Sprintec (ethinyl estradiol and norgestimate) as ordered by your doctor. Read all information given to you. Follow all instructions closely.
Follow how to use as you have been told by the doctor or read the package insert.
Take Tri-Sprintec (ethinyl estradiol and norgestimate) at the same time of day.
Take with or without food. Take with food if it causes an upset stomach.
If you also take colesevelam, take it at least 4 hours after you take Tri-Sprintec (ethinyl estradiol and norgestimate).
Do not skip doses, even if you do not have sex very often.
If you throw up or have diarrhea, Tri-Sprintec (ethinyl estradiol and norgestimate) may not work as well to prevent pregnancy. Use an extra form of birth control, like condoms, until you check with your doctor.
If you miss 2 periods in a row, take a pregnancy test before starting a new cycle.
The following serious adverse reactions with the use of COCs are discussed elsewhere in labeling:
Serious cardiovascular events and stroke [see BOX WARNING and WARNINGS AND PRECAUTIONS]
Vascular events [see WARNINGS AND PRECAUTIONS]
Liver disease [see WARNINGS AND PRECAUTIONS]
Adverse reactions commonly reported by COC users are:
Irregular uterine bleeding
Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of Tri-Sprintec was evaluated in 4,826 healthy women of child-bearing potential who participated in 6 clinical trials and received at least 1 dose of Tri-Sprintec for contraception. Two trials were randomized active-controlled trials and 4 were uncontrolled open-label trials. In 3 trials, subjects were followed for up to 24 cycles; in 2 trials, subjects were followed for up to 12 cycles; and in 1 trial, subjects were followed for up to 6 cycles.
Common Adverse Reactions (= 2% Of Subjects)
The most common adverse reactions reported by at least 2% of the 4,826 women were the following in order of decreasing incidence: headache/migraine (33.6%), breast issues (including breast pain, enlargement, and discharge) (8%), vaginal infection (7.1%), abdominal/gastrointestinal pain (5.6%), mood disorders (including mood alteration and depression) (3.8%), genital discharge (3.2%), and changes in weight (including weight fluctuation, increased or decreased) (2.5%).
Adverse Reactions Leading To Study Discontinuation
Over the trials, between 9 to 27% of subjects discontinued the trial due to an adverse reaction. The most common adverse reactions (=1%) leading to discontinuation were: metrorrhagia (4.3%), nausea/vomiting (2.8%), headache/migraine (2.4%), mood disorders (including depression and mood altered) (1.1%), and weight increased (1.1%).
Serious Adverse Reactions
breast cancer (1 subject), carcinoma of the cervix in situ (1 subject), hypertension (1 subject), and migraine (2 subjects).
The following additional adverse drug reactions have been reported from worldwide postmarketing experience with norgestimate/ethinyl estradiol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Consult the labeling of concurrently used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.
No drug-drug interaction studies were conducted with Tri-Sprintec.
Effects Of Other Drugs On Combined Oral Contraceptives
Substances Decreasing The Plasma Concentrations Of COCs:
Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the plasma concentrations of COCs and potentially diminish the effectiveness of COCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampicin, topiramate, rifabutin, rufinamide, aprepitant, and products containing St. John’s wort. Interactions between hormonal contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability.
Colesevelam, a bile acid sequestrant, given together with a COC, has been shown to significantly decrease the AUC of EE. The drug interaction between the contraceptive and colesevelam was decreased when the two drug products were given 4 hours apart.
Substances Increasing The Plasma Concentrations Of COCs:
Co-administration of atorvastatin or rosuvastatin and certain COCs containing ethinyl estradiol (EE) increase AUC values for EE by approximately 20 to 25%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase plasma hormone concentrations.
Human Immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) Protease Inhibitors And Nonnucleoside Reverse Transcriptase Inhibitors:
Significant changes (increase or decrease) in the plasma concentrations of estrogen and/or progestin have been noted in some cases of co-administration with HIV protease inhibitors (decrease [e.g., nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir] or increase [e.g., indinavir and atazanavir/ritonavir])/HCV protease inhibitors (decrease [e.g., boceprevir and telaprevir]) or with non-nucleoside reverse transcriptase inhibitors (decrease [e.g., nevirapine] or increase [e.g., etravirine]).
Effects Of Combined Oral Contraceptives On Other Drugs
COCs containing EE may inhibit the metabolism of other compounds (e.g., cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole) and increase their plasma concentrations.
COCs have been shown to decrease plasma concentrations of acetaminophen, clofibric acid, morphine, salicylic acid, temazepam and lamotrigine. Significant decrease in plasma concentration of lamotrigine has been shown, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because the serum concentration of thyroid-binding globulin increases with use of COCs.
Interference With Laboratory Tests
The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.
There have been no reports of serious ill effects from overdosage of oral contraceptives, including ingestion by children. Overdosage may cause withdrawal bleeding in females and nausea.
