Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction.
Combination of ethinyl estradiol and levonorgestrel suppresses gonadotropin-releasing hormone (Gn RH) secretion from the hypothalamus, inhibiting pituitary release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby preventing ovulation. Additionally, it thickens cervical mucus, impeding sperm penetration, and alters endometrial receptivity.
Temporary relief of symptoms due to hay fever or other upper respiratory allergies: nasal congestion, sinus pressure, sneezing, runny nose, itching of nose or throat, and itchy, watery eyes due to allergies.,Temporary reduction of fever.,Relief of minor aches and pains associated with the common cold, headache, toothache, muscular aches, backache, menstrual cramps, and arthritis pain.
Prevention of pregnancy,Treatment of moderate acne vulgaris (in women ≥15 years who have achieved menarche and desire contraception),Contraception in women with heavy menstrual bleeding (off-label)
Ibuprofen 200 mg and pseudoephedrine HCl 30 mg per tablet. Usual adult dose: 1-2 tablets orally every 4-6 hours as needed, not to exceed 6 tablets in 24 hours.
One tablet (ethinyl estradiol 20 mcg, levonorgestrel 0.1 mg) orally once daily at the same time each day for 21 days, followed by 7 days of placebo. For initiation, start on the first day of menstrual period or first Sunday after onset of menses.
Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Levonorgestrel: terminal half-life ~17-20 hours (range 11-25 hr). Ethinyl estradiol: biphasic; terminal half-life ~13-27 hours (mean ~17 hr). Clinical context: steady-state achieved within 5-7 days. The half-life supports once-daily dosing with at least 24-hour contraceptive coverage.
Ibuprofen is primarily metabolized by cytochrome P450 (CYP) enzymes, mainly CYP2C9, to inactive metabolites (hydroxyibuprofen and carboxyibuprofen). Pseudoephedrine is partially metabolized in the liver by N-demethylation to an inactive metabolite.
Ethinyl estradiol is primarily metabolized by CYP3A4 and undergoes conjugation (glucuronidation and sulfation). Levonorgestrel is metabolized by CYP3A4 and reduction, with conjugation to glucuronide and sulfate conjugates.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Renal: ethinyl estradiol (UE2) and levonorgestrel (LNG) metabolites primarily excreted in urine (UE2: ~40% as sulfate and glucuronide conjugates; LNG: ~25% as glucuronides). Fecal/biliary: ~40% (UE2) and ~45% (LNG) eliminated in feces via bile. Unchanged drug excretion is negligible.
Ibuprofen: 99% bound to albumin; pseudoephedrine: negligible protein binding.
Levonorgestrel: 97-99% bound to albumin and sex hormone-binding globulin (SHBG). Ethinyl estradiol: 98-99% bound, primarily to albumin (98.5%), with minor binding to SHBG. Free fractions: LNG ~1%, UE2 ~1.0-1.5%.
Ibuprofen: 0.1-0.2 L/kg; pseudoephedrine: 2.5-3 L/kg.
Levonorgestrel: Vd ~1.8 L/kg (range 1.5-2.0 L/kg). Ethinyl estradiol: Vd ~2.5-3.5 L/kg (mean ~2.9 L/kg). Indicates extensive tissue distribution, including target organs (ovaries, endometrium, breast). Not clinically adjusted for obesity.
Oral: ibuprofen 80-100%; pseudoephedrine 100%.
Oral: levonorgestrel ~95-100% (highly bioavailable). Ethinyl estradiol ~45-55% (first-pass metabolism reduces bioavailability; interindividual variability due to gut wall and hepatic conjugation). Both are prodrugs requiring hydrolysis for activity.
For pseudoephedrine: Cr Cl <30 m L/min, reduce dose by 50% or administer every 12 hours. For ibuprofen: avoid use if Cr Cl <30 m L/min; if Cr Cl 30-59 m L/min, use lowest effective dose and monitor renal function.
No specific GFR-based dose adjustments are recommended; however, use with caution in patients with renal impairment due to potential fluid retention and hypertension.
For ibuprofen: Child-Pugh class A and B: no adjustment necessary; Child-Pugh class C: avoid use. For pseudoephedrine: use with caution in severe hepatic impairment; no specific dose adjustment recommended, but monitor for adverse effects.
Contraindicated in patients with severe hepatic disease (Child-Pugh class C) or active liver disease. In mild to moderate impairment (Child-Pugh A or B), use only if benefits outweigh risks; no specific dose reduction guidelines are available.
Not indicated for children under 12 years of age. For children 12 years and older: same as adult dose (1-2 tablets every 4-6 hours, max 6 tablets per day). Weight-based: not routinely used; safety and efficacy not established for <25 kg.
Approved for postmenarchal adolescents; same dosing as adults: one tablet orally once daily for 21 days followed by 7 days of placebo. No weight-based adjustments are recommended.
For ibuprofen: use lowest effective dose for shortest duration; monitor renal function and GI bleeding risk. For pseudoephedrine: initiate at lower doses (e.g., one tablet every 6 hours) due to increased sensitivity and risk of hypertension, urinary retention, and CNS effects.
Not indicated for use in postmenopausal women; no specific geriatric dosing adjustments are necessary if used off-label, but consider increased risk of thrombotic events in older women.
Cardiovascular risk: NSAIDs may increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use and in patients with cardiovascular risk factors. Contraindicated for perioperative pain in coronary artery bypass graft (CABG) surgery. Gastrointestinal risk: NSAIDs increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Elderly patients and those with prior peptic ulcer disease and/or GI bleeding are at greater risk.
Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive use. The risk increases with age, particularly in women over 35 years, and with heavy smoking (≥15 cigarettes per day). Women over 35 who smoke should not use this medication.
Cardiovascular effects: may increase risk of heart attack or stroke; use lowest effective dose for shortest duration. Gastrointestinal effects: may cause GI ulceration, bleeding, perforation. Renal effects: avoid in advanced renal disease; monitor renal function. Hepatic effects: may cause liver enzyme elevation; discontinue if liver disease develops. Anaphylactic reactions: may occur in patients with or without prior NSAID sensitivity. Asthma: may cause bronchospasm. Hypertension: may worsen hypertension. Avoid in late pregnancy due to risk of premature closure of ductus arteriosus. Pseudoephedrine: may cause nervousness, dizziness, insomnia, hypertension, arrhythmias; use with caution in patients with cardiovascular disease, diabetes, glaucoma, prostatic hypertrophy, hyperthyroidism. Avoid in severe hypertension or coronary artery disease.

Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
No specific food restrictions. Grapefruit juice may slightly increase ethinyl estradiol levels but not clinically significant. High-fat meals do not affect absorption. Avoid excessive alcohol as it may impair compliance.
First trimester: Possible increased risk of cardiovascular malformations and gastroschisis with NSAID use. Second trimester: No specific malformation risk reported, but avoid prolonged use due to potential oligohydramnios. Third trimester: NSAIDs (including ibuprofen) are contraindicated due to risk of premature ductus arteriosus closure and oligohydramnios. Pseudoephedrine: Limited data; possible association with gastroschisis if used in first trimester; avoid due to vasoconstrictive effects.
Pregnancy category X. Use contraindicated in pregnancy. First trimester exposure associated with cardiovascular defects (e.g., VSD), neural tube defects, and cleft lip/palate. Second and third trimester exposure may cause fetal adrenal suppression, hepatic dysfunction, and virilization of female genitalia due to progestin component (levonorgestrel). Increased risk of ectopic pregnancy if conception occurs during use.
Ibuprofen: Excreted in low levels (M/P ratio ~0.006); considered compatible with breastfeeding. Pseudoephedrine: Excreted in breast milk (M/P ratio ~2.5-3.5); may reduce milk production and cause irritability in infants; use with caution.
Excreted in breast milk. Levonorgestrel M/P ratio approximately 0.3–0.4. Small amounts of ethinyl estradiol present. May reduce milk production and quality due to estrogen component. Use only if benefit outweighs risk; consider alternative contraception. American Academy of Pediatrics considers it compatible with nursing.
Ibuprofen: No specific dose adjustment recommended for pregnancy; however, avoid use in third trimester. Pseudoephedrine: No dose adjustment studied; use lowest effective dose for shortest duration. Neither drug is recommended for regular use during pregnancy.
Contraindicated. No dose adjustments apply as drug must be discontinued immediately if pregnancy suspected or confirmed. Pharmacokinetic changes in pregnancy (increased clearance, volume of distribution) not relevant due to contraindication.
Combination of ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen may increase blood pressure, counteracting pseudoephedrine's vasoconstriction; monitor in hypertensive patients. Avoid in patients with severe CAD, uncontrolled HTN, or within 2 weeks of MAOI use.
ALESSE is a combined oral contraceptive (COC) containing ethinyl estradiol (20 mcg) and levonorgestrel (100 mcg). It is indicated for contraception and treatment of acne vulgaris in women aged ≥14. Monitor for thromboembolic events, especially in smokers >35 years. Assess for contraindications including migraines with aura, hypertension, and history of DVT/PE. Advise use of backup contraception if a pill is missed. Start on first day of menses or first Sunday after onset. Check BP at baseline and annually. Counsel on increased risk of VTE, especially in first year.
