Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Ketotifen is a selective histamine H1-receptor antagonist and mast cell stabilizer that inhibits the release of inflammatory mediators such as histamine and leukotrienes from mast cells.
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.
FDA-approved for the prevention and treatment of ocular itching associated with allergic conjunctivitis
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.
One drop in each affected eye twice daily (approximately 8 hours apart) as needed. The lens should be removed prior to instillation and can be reinserted after at least 10 minutes.
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.

"Lisdexamfetamine, a prodrug of dextroamphetamine, increases central nervous system (CNS) arousal via dopamine and norepinephrine release, counteracting the sedative effects of ketotifen, a mast cell stabilizer with histamine H1-receptor antagonism and CNS depressant properties. The interaction results in reduced sedative efficacy of ketotifen, potentially affecting therapeutic outcomes in allergic conditions where sedation is beneficial, such as severe pruritus or urticaria. Clinically, patients may experience decreased drowsiness or sleepiness, which could be undesirable if ketotifen is prescribed specifically for its soporific effects."
"Pseudoephedrine, a sympathomimetic amine, exerts central nervous system (CNS) stimulant effects by indirectly activating adrenergic receptors, which can counteract the sedative properties of ketotifen, a histamine H1-receptor antagonist with mast cell stabilizing activity. This pharmacodynamic antagonism may reduce the therapeutic efficacy of ketotifen in managing allergic conditions, particularly its ability to cause drowsiness as a side effect. Clinically, patients may experience diminished sedation, potentially leading to decreased compliance or altered therapeutic outcomes in conditions where sedation is beneficial."
"Hydroxyamphetamine, an indirect-acting sympathomimetic amine, stimulates the release of norepinephrine from presynaptic nerve terminals, leading to activation of alpha- and beta-adrenergic receptors. This produces central nervous system (CNS) stimulation that may oppose the sedative effects of ketotifen, a histamine H1-receptor antagonist with sedative properties. Consequently, coadministration may result in reduced efficacy of ketotifen for sedation or sleep induction, potentially compromising its therapeutic benefit in conditions requiring CNS depression (e.g., allergic rhinitis, urticaria)."
