infections (eg, tinea
pedis)
*Advantages of one topical drug over another for most infections are not clear. For skin infections,allylamines have good activity against dermatophytes but weaker activity against Candida;imidazoleshave better activity against both dermatophytes and Candida. Adverse effects are rare, but all topicalantifungals can cause skin irritation, burning, and contact dermatitis. Drug doses may vary by indication.Oral antifungals can cause hepatitis and neutropenia. Periodic laboratory monitoring of hepatic functionand of CBC is recommended when oral antifungals (eg, itraconazole
, terbinafine
) are given for > 1 mo.Drug interactions may occur. For example, itraconazole
may interact with lovastatin
,midazolam
, simvastatin
, and triazolam
. Cisapride
, dofetilide
, pimozide
, orquinidine
should not be used with itraconazole
; taking these drugs with itraconazole
may cause cardiac arrhythmias.

Things to consider when using
antifungal medicinesBefore you take antifungals there are a number of things you should discuss with your GP.
Allergies
You are generally advised not to take an antifungal medicine if you are allergic to the medicine or any
of the ingredients used in it.
In some cases, such as when treating invasive fungal infections in hospital, your doctors may feel the
benefit of the medicine outweighs the risk of an allergic reaction. They may decide to use the
medicine and monitor you closely.
Other conditions
Be careful with some oral antifungals if you have problems with your heart, liver or kidneys.
Discuss your condition with your GP or pharmacist to find out which antifungal medicines are safe for
you to use.
Topical antifungals
If you are using a topical antifungal medicine, such as a cream, avoid it coming into contact with:
your eyes
moist linings (mucous membranes), for example, inside your nose or mouth (unless it
is a gel that is supposed to be used in your mouth)
Contraceptives
Some antifungal medicines are designed to be used on a man's penis or in or around a woman's
vagina. Antifungal creams or vaginal suppositories (pessaries) are sometimes used to treat thrush.
However, these types of antifungal medicines can damage latex condoms and diaphragms, making
them less effective. Use a different method of contraception while you are using the antifungal
medicine, or avoid having sex.
Some types of antifungal medicines can also interact with oestrogens and progestogens, which arefound in some types of hormonal contraceptives, such as thecombined contraceptive pill.You may
experience some breakthrough bleeding while taking your antifungal medicine, but your contraceptive
protection should not be affected.
Only oral antifungal medicines interact with oestrogens.
Pregnancy
Many antifungal medicines are not suitable to take during pregnancy. Check the patient information
leaflet that comes with your medicine to find out.
However, if you havevaginal thrush during pregnancy, your GP may prescribe an antifungalsuppository that can be inserted into your vagina (a pessary) or an antifungal cream.

Breastfeeding
Small amounts of some medicines can pass into your breast milk and may then be passed on to your
baby if you are breastfeeding. Check the patient information leaflet that comes with your antifungal
medicine, as many medicines should not be taken while breastfeeding.
Antifungal medicines are used to treat fungal infections.
Fungal infections
Fungi are plant-like organisms that feed by breaking down livingtissue.Fungi that cause infections in humans are known asdermatophytes. Dermatophytes are particularly attracted to a typeof tissue called keratin, which is a tough, waterproof tissue foundin many parts of the body such as in the:
nails
hair
skins outer surface
This explains why fungal infections often occur on the skin, nailsand scalp.Common funga l in fec tions
Antifungal medicines may be used to treat the following common
fungal infections: ringwormwhich causes a ring-like red rash on the skin of the body or scalp
athletes footwhich affects the skin on the feet, causing it to become red, flaky and
itchy
fungal nail infectionwhich causes the toenails or fingernails to become thickened
and discoloured, and sometimes brittle, with pieces of nail breaking off
vaginal thrushwhich causes irritation and swelling of the vagina and vulva (the
female external sexual organs)

Invasiv e fung al infect ion s
Invasive fungal infections are a less common, but more serious,type of fungal infection. They are infections that occur deep inside
the bodys tissue or in one of the organs, such as in the: brain for example, fungalmeningitis,where a fungus causes an infection of the
protective membranes that surround the brain and spinal cord
lungsfor example,aspergillosis,which is a lung infection caused by a fungal mould
called aspergillus
People with a weakened immune system (the bodys naturaldefence system) are particularly vulnerable to invasive fungalinfections. Those at risk include:
people withHIV and AIDS
people having high-dosechemotherapy to treat cancer
people who are taking immunosuppresantsmedicines to suppress the immune
system (the bodys natural defence against infection and illness), often used after an
organ transplant
How antifungal medicines work
Antifungal medicines work by either:
killing the fungal cellsfor example, by affecting a substance in the cell wall, causing
the contents of the cell to leak out and the cell to die
preventing the fungal cells from growing and reproducing
Types of antifungal medicines
Antifungal medicines are used in several ways, depending onyour specific fungal infection. The main types of antifungalmedicines include:
topical antifungals, applied to the skin, hair or nails
oral antifungals, swallowed in capsule, pill or liquid form
intravenous antifungals, injected into your bloodstream
