Please read this leaflet carefully before taking
Rizuderm Capsules. Keep the leaflet in case
you want to refer to it again. If you want to know
more about Rizuderm Capsules or have any
questions, you should ask your doctor or


Rizuderm Capsules contain Isotretinoin which
belongs to a group of medicines known as
retinoids that are normally used to treat skin
Rizuderm Capsules are used to treat severe
acne, for patients whose acne has not responded
to other treatments. Their use must be supervised
by a dermatologist (a doctor who specialises in
the treatment of skin problems).
Rizuderm Capsules should not be used to treat
acne occurring before the onset of puberty.
You must not take Rizuderm Capsules and
should talk to your doctor immediately if you:
• are pregnant or think you may be pregnant (see
’Important advice for female patients’ in the box
• have liver disease
• are breast-feeding
• are taking certain antibiotics called tetracyclines
• are allergic to Rizuderm Capsules or any of the
ingredients it contains
• have very high levels of vitamin A in your body
(Hypervitaminosis A)
• have very high levels of cholesterol or
triglycerides (a fat like substance) in your blood
• are allergic to soya
Rizuderm capsules do not contain peanut oil but
do contain soya oil and some patients who are
allergic to peanuts may suffer a cross reactivity to

soya protein. If you have a peanut allergy you
should discuss this with your doctor.
Important Advice for Female Patients.
Rizuderm will damage an unborn baby so:
• You must not take Rizuderm Capsules if you
are pregnant or think you may be pregnant.
• You must not take Rizuderm Capsules if you
are breast-feeding.
• You must use one, preferably two, effective
methods of contraception (including condom,
cap or spermicide) for one month before
Rizuderm treatment, during treatment and for
one month after treatment ends.
• Your doctor will ask you to take a pregnancy
test before, during and after your treatment.
These must be negative. You should start
taking Rizuderm Capsules on the second or
third day of your menstrual cycle.
• You must not become pregnant at any time
during treatment or for one month after
treatment ends.
• Contact your dermatologist immediately if you
do become pregnant or think you may be
pregnant during treatment or in the first month
after treatment ends.
Advice for Male patients
Isotretinoin treatment does not appear to damage
sperm. Isotretinoin and its metabolites are
present at very low levels in your semen. These
levels are considered too low to harm the unborn
baby of your female partner.
Advice for all patients:
• Tell your doctor if you have or have had any
mental illness including depression, psychosis
or suicidal behaviour.
• Tell your doctor if you, or members of your
family, have a history of high fat levels in the
blood. Your doctor may reduce the dose of
Rizuderm or suggest you go on a low-fat diet.
Rizuderm may increase blood fats and may
also increase liver enzymes (transaminases).

Blood tests will be performed before, during and
after Rizuderm treatment to check your blood
fat and liver enzyme levels.
• Tell your doctor if you have diabetes mellitus
(sugar diabetes), are overweight, or you are an
alcoholic. Rizuderm may increase your blood
sugar levels, so your doctor may want to
monitor this during treatment.
• Your skin and lips are likely to get dry. Use a
moisturiser and lip balm during treatment.
• Avoid chemical dermabrasion and laser
treatment of the skin and wax depilation during
and for at least 6 months after treatment as they
could cause scarring or irritation of the skin.
• Avoid too much sun and do not use a sunlamp
or sunbed as your skin may be more sensitive.
Before going out in the sun apply a sun block to
exposed skin, particularly in strong sunlight.
• Do not donate blood during therapy or for at
least one month after treatment with Rizuderm.
• Do not give your medication to anyone else.
Return any unused capsules to the pharmacy.
Taking/using other medicines
• Do not use any other acne treatments unless
your doctor has told you to.
• Do not take tetracycline antibiotics when on
Rizuderm treatment.
• Do not take any vitamin A supplements.
Tell your doctor or pharmacist if you are taking or
have recently taken any other medicine including
those obtained without a prescription.

Always take the capsules as your doctor tells you
to. Your doctor will tell you how many to take,
which may change after a few weeks of
treatment. This will depend on how you respond
to your medicine.
Adolescents, adults and the elderly:
The usual starting dose is 0.5mg/kg daily, e.g. if

breathing, swelling of face, tongue or throat,
itching, rash

use of a good moisturising cream and lip balm
from the start of treatment
• the inside of the nose may become dry and
"crusted", which may lead to mild nosebleeds.
Applying a thin layer of petroleum jelly gently to
the inside of the nose will help
• skin rash, mild itching and slight peeling of the
skin, or red, fragile skin

a problem if you wear contact lenses. Ask your

temporary and persistent hair thinning is rare.
Your hair should return to normal after the
treatment ends.

are cells in your blood involved in fighting
infections, may decrease in number
• arthritic pain, soreness of the tendons

normal course of treatment, but these are very
unlikely during a normal course of treatment.
Skin and hair problems (Unknown frequency)
Serious skin rashes (erythema multiforme,
Stevens-Johnson syndrome, and toxic epidermal
necrolysis), which are potentially life-threatening
and require immediate medical attention. These
appear initially as circular patches often with
central blisters usually on arms and hands or legs
and feet, more severe rashes may include
blistering of the chest and back. Additional
symptoms such as infection of the eye
(conjunctivitis) or ulcers of the mouth, throat or
nose may occur. Severe forms of rash may
progress to widespread peeling of the skin which
can be life threatening. These serious skin rashes
are often preceded by headache, fever, body
aches (flu-like symptoms).
If you develop a rash or these skin symptoms,
stop taking Rizuderm and contact your doctor
