Leah, a young woman, comes into
the pharmacy carrying a baby and
accompanied by a toddler. She
says that she, her husband and two
children are going on holiday to the
coast over Christmas and she would
like some advice about suitable sun
protection for her family. Her toddler
is two years old and the baby is four
Which of the following is the most
appropriate advice to give to Leah?
a) Leah should be advised not to use
sunscreen on her baby, as infants
under six months of age have
sensitive skin and increased skin
permeability. This makes them
more susceptible to skin reactions
and toxicity resulting from
absorption of sunscreen chemicals.
You recommend she keeps the
baby in the shade and, if he has to
be out in the sun, that she protects
his skin with clothes and a hat.
b) You recommend that Leah, her
husband and two-year-old daughter
she should use a sunscreen that
states on the label that it is SPF30+
and broad spectrum, as this will
protect them from both UVA and
UVB rays. A sunscreen that is only
labelled SPF30+ may only protect
them from UVA radiation.
c) For optimum protection, they
should apply the sunscreen
immediately before going out in the
sun. Leah and her husband should
use approximately one teaspoon
of sunscreen on each arm and
leg, on the back and on the torso
and about half that amount on the
face and neck. A pro rata amount
should be used on the two-year-old,
appropriate for her size.
d) Sunscreen products containing
inorganic chemicals such as titanium
dioxide are less likely to cause skin
irritation/rashes than those containing
organic filters such as cinnamates
and may be more suitable for people
with sensitive skin.

Claire, a 27 year old nurse, returns
with an unopened box of Logynon ED
dispensed at your pharmacy last week
and asks if she can obtain a refund.
She and her husband have decided to
start a family in a month's time when
he returns from an overseas business
trip. She does not sleep well while he
is away and would like to exchange the
Logynon ED for a bottle of Thursday
Plantation Hypericum -- St. John's wort
(which contains equiv. dry herb 1500 mg
hypericum perforatum per 3 mL liquid).
Claire is a very good customer and she
used the hypericum liquid several years
ago with good results.
Which of the following would be the
most appropriate response?
a) Inform Claire that you will take the
tablets back and provide the mixture
at no cost; but that you will be unable
to re-use the dispensed tablets and
will need to dispose of them.
b) Advise Claire that it would be
prudent to avoid using the mixture
at this time if she is intending to fall
pregnant when her husband returns.
The questions in this series are independently researched and compiled by PSA commissioned authors and peer reviewed.
Each question is worth 0.5 CPD credits.
