Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Afrinol is a sympathomimetic amine that acts as a nasal decongestant by stimulating alpha-1 adrenergic receptors in the vascular smooth muscle of nasal blood vessels, causing vasoconstriction and reducing nasal congestion. It also has weak alpha-2 agonist activity.
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.
Temporary relief of nasal congestion due to colds, hay fever, or other upper respiratory allergies.
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.

None.
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.
Hypertension, cardiovascular disease, hyperthyroidism, diabetes mellitus, increased intraocular pressure, prostatic hyperplasia; use caution in elderly patients; do not exceed recommended dosage.
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.
Hypersensitivity to any component; concurrent use or recent use (within 14 days) of MAO inhibitors; severe hypertension or coronary artery disease.
Hypersensitivity to ibuprofen, pseudoephedrine, or any component of the formulation. History of asthma, urticaria, or allergic-type reaction after taking aspirin or other NSAIDs. In the setting of coronary artery bypass graft (CABG) surgery. Severe hypertension. Coronary artery disease. Concurrent use with or within 14 days of monoamine oxidase inhibitors (MAOIs) due to risk of hypertensive crisis. Pregnancy (third trimester).
Avoid excessive caffeine intake as it may increase stimulant effects. No significant food interactions known.
Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
Afrinol (pseudoephedrine) is generally considered low risk during pregnancy. First trimester: Some studies suggest a possible association with gastroschisis, but data are inconsistent. Second and third trimesters: Avoid due to risk of uterine vasoconstriction and potential fetal hypoxia, especially near term. Overall, FDA Pregnancy Category C.
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.
Pseudoephedrine is excreted into breast milk in small amounts (M/P ratio approximately 2.6–3.5). Use with caution as it can reduce milk production and may cause irritability in the infant. A single dose is likely safe, but chronic use is not recommended.
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.
No specific dose adjustments are established for pregnancy. However, due to increased plasma volume and renal clearance, the duration of action may be shorter. Use the lowest effective dose for the shortest duration, typically 60 mg every 4–6 hours (max 240 mg/day).
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.
