treatments) to subside before using a topical retinoid . alternating a preparation that causes peeling with a topical

retinoid may give rise to contact dermatitis (reduce

frequency of retinoid application). avoid accumulation in

angles of the nose . avoid contact with eyes, nostrils,

mouth and mucous membranes, eczematous, broken or

sunburned skin . avoid exposure to UV light (including

Discontinue treatment if skin peeling severe or

haemorrhagic diarrhoea develops.

Visual disturbances require expert referral and possible

withdrawal.

Psychiatric side-effects could require expert referral.

l CONCEPTION AND CONTRACEPTION

Pregnancy prevention

▶ With oral use Effective contraception must be used. In

women of child-bearing potential, exclude pregnancy up

to 3 days before treatment (start treatment on day 2 or 3 of

menstrual cycle), every month during treatment (unless

there are compelling reasons to indicate that there is no

risk of pregnancy), and 5 weeks after stopping treatment—

perform pregnancy test in the first 3 days of the menstrual

cycle. Women must practise effective contraception for at

least 1 month before starting treatment, during treatment,

and for at least 1 month after stopping treatment. Women

should be advised to use at least 1 method of

contraception, but ideally they should use 2 methods of

contraception. Oral progestogen-only contraceptives are

not considered effective. Barrier methods should not be

used alone, but can be used in conjunction with other

contraceptive methods. Each prescription for isotretinoin

should be limited to a supply of up to 30 days’ treatment

and dispensed within 7 days of the date stated on the

prescription; repeat prescriptions or faxed prescriptions

are not acceptable. Women should be advised to

discontinue treatment and to seek prompt medical

attention if they become pregnant during treatment or

within 1 month of stopping treatment.

▶ With topical use Females of child-bearing age must use

effective contraception (oral progestogen-only

contraceptives not considered effective).

l PREGNANCY Contra-indicated in pregnancy (teratogenic).

l BREAST FEEDING Avoid.

l HEPATIC IMPAIRMENT

▶ With oral use Manufacturer advises avoid—limited

information available.

l RENAL IMPAIRMENT

Dose adjustments ▶ With oral use In severe impairment,

reduce initial dose (e.g. 10 mg daily) and increase gradually

up to 1 mg/kg daily as tolerated.

l MONITORING REQUIREMENTS

▶ With oral use Measure hepatic function and serum lipids

before treatment, 1 month after starting and then every

3 months (reduce dose or discontinue if transaminase or

serum lipids persistently raised).

l PRESCRIBING AND DISPENSING INFORMATION Isotretinoin

is an isomer of tretinoin.

l PATIENT AND CARER ADVICE

▶ With oral use Warn patient to avoid wax epilation (risk of

epidermal stripping), dermabrasion, and laser skin

treatments (risk of scarring) during treatment and for at

least 6 months after stopping; patient should avoid

exposure to UV light (including sunlight) and use

sunscreen and emollient (including lip balm) preparations

from the start of treatment. Patients and carers should be

told how to recognise signs and symptoms of psychiatric

disorders such as depression, anxiety, and rarely suicidal

thoughts.

▶ With topical use Patients should be warned that some

redness and skin peeling can occur initially but settles with

time. If undue irritation occurs, the frequency of

application should be reduced or treatment suspended

until the reaction subsides; if irritation persists,

discontinue treatment. Several months of treatment may

be needed to achieve an optimal response and the

treatment should be continued until no new lesions

develop. If sun exposure is unavoidable, an appropriate

sunscreen or protective clothing should be used.

SYSTEMIC CARDIOVASCULAR EFFECTS (JUNE 2017)

Systemic cardiovascular effects including bradycardia,

hypotension, and dizziness have been reported after

application of brimonidine gel. To minimise the

possibility of systemic absorption, it is important to

avoid application to irritated or damaged skin, including

after laser therapy.

MHRA/CHM ADVICE: BRIMONIDINE GEL (MIRVASO ®): RISK OF

EXACERBATION OF ROSACEA (NOVEMBER 2016)

Symptom exacerbation has been reported very

commonly in patients treated with brimonidine gel.

Treatment should be initiated with a small amount of gel

(less than the maximum dose) for at least 1 week, then

increased gradually, based on tolerability and response.

Patients should be counselled on the importance of not

exceeding the maximum daily dose, and advised to stop

treatment and seek medical advice if symptoms worsen

7 Scalp and hair conditions

Scalp and hair conditions

Overview

Dandruff is considered to be a mild form of seborrhoeic

dermatitis. Shampoos containing antimicrobial agents such

as pyrithione zinc (which are widely available) and

selenium below may have beneficial effects. Shampoos

containing tar extracts may be useful and they are also used

in psoriasis. Ketoconazole shampoo p. 1233 should be

considered for more persistent or severe dandruff or for

seborrhoeic dermatitis of the scalp.

Corticosteroid gels and lotions can also be used.

Shampoos containing coal tar with salicylic acid p. 1255

may also be useful. A cream or an ointment containing coal

tar with salicylic acid is very helpful in Psoriasis p. 1239 that

affects the scalp. Patients who do not respond to these

treatments may need to be referred to exclude the possibility

of other skin conditions.

Cradle cap in infants may be treated with coconut oil or

olive oil applications followed by shampooing.

Hirsutism

Hirsutism may result from hormonal disorders or as a sideeffect of drugs such as minoxidil p. 1275, corticosteroids,

anabolic steroids, androgens, danazol p. 742, and

progestogens.

Weight loss can reduce hirsutism in obese women.

Women should be advised about local methods of hair

removal, and in the mildest cases this may be all that is

required.

Eflornithine p. 1275 an antiprotozoal drug, inhibits the

enzyme ornithine decarboxylase in hair follicles. Topical

eflornithine can be used as an adjunct to laser therapy for

facial hirsutism in women.

Co-cyprindiol p. 1267 may be effective for moderately

severe hirsutism. Metformin hydrochloride p. 692 is an

alternative in women with polycystic ovary syndrome

[unlicensed indication]. Systemic treatment is required for

6–12 months before benefit is seen.

Androgenetic alopecia

Finasteride p. 787 is licensed for the treatment of

androgenetic alopecia in men. Continuous use for

3–6 months is required before benefit is seen, and effects are

reversed 6–12 months after treatment is discontinued.

Topical application of minoxidil may stimulate limited hair

growth in a small proportion of adults but only for as long as

it is used.
