	A second study (Van Heerbeek, 2002) investigated the effect of xylometazoline on eustachian tube function in 80 children with ventilation tubes due to persistent otitis media effusion compared to placebo. Each child was treated with intranasal administration of five drops of 0.05% xylometazoline hydrochloride or placebo. The Group noted this study demonstrated no significant difference on eustachian tube function compared to placebo. The Group noted a further study investigating the effect of phenylephrine (Turner, 1996) on middle ear pressure in children aged six to eighteen months with the common cold compared to placebo.

	Nasal sprays based on saline (0.9%), xylometazoline hydrochloride (0.1%), and the combinations hydroxypropylmethylcellulose/succinic acid/disodium succinate or Galphimia glauca/ Luffa operculata/ Sabadilla were ineffective. The combination of sodium hypochlorite (0.08%) with lithium magnesium sodium silicate achieved a reduction factor of 2.2 , which, however, is not considered sufficient for virucidal activity. Since the product forms a gel matrix that may interfere with the virus, an effect may be achieved in vivo if need be. However, the tolerability of sodium hypochlorite for long-term use requires clarification. 2.2 Preventive efficacy in in vivo and in-use studies Gargling Gargling with hypertonic saline (2% - 3%) 3 times/d significantly shortened the duration of illness from viral influenza, with the reduction in viral shedding reducing the incidence of illness by 35%, even among people living in the same household.

	The concomitant use of xylometazoline with monoamine oxidase (MAO) inhibitors or tri- and tetra-cyclic antidepressants, may cause an increase in blood pressure due to the cardiovascular effects of these substances (see Contraindications). No foetal toxicity or fertility studies have been carried out in animals. In view of its potential systemic vasoconstrictor effect, it is advisable to take the precaution of not using Otrivine during pregnancy. No evidence of any adverse effect on the breast-fed infant. However, it is not known if xylometazoline is excreted in breast milk, therefore caution should be exercised and Otrivine should be used only on the advice of a doctor whilst breastfeeding. Otrivine has no or negligible influence on the ability to drive and use machines.
