Hypertensive interactions may occur between sympathomimetic amines such as oxymetazoline and monoamine oxidase inhibitors (MAOIs) (see Section 4.4) and/or reversible inhibition of monoamine oxidase (RIMA) and Moclobemide.
Oxymetazoline may reduce the efficacy of beta-blocking drugs, methyl dopa or other anti-hypertensive drugs including adrenergic neurone blockers.
There is a possible increased risk of hypertension and arrhythmias when tricyclic antidepressants, appetite suppressants and amphetamine-like psychostimulants are given with sympathomimetics such as oxymetazoline.
Possible additive cardiovascular toxicity may occur when sympathomimetics are given with antiparkinsonian drugs such as bromocriptine
There is an increased risk of dysrhythmias when cardiac glycosides are given with sympathomimetics such as oxymetazoline.
There is an increased risk of ergotism when ergot alkaloids (ergotamine & methysergide) are given with sympathomimetics such as oxymetazoline.
Due to insufficient evidence on the use of the product in pregnancy and lactation, use of the product should be avoided unless on the advice of a physician.
No effects on ability to drive and use machines have been observed.
In general no severe undesirable effects are expected.
