Standard Indications

Specific Indications

ISENTRESS, in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus (HIV-1) infection in adults,

adolescents and children from the age of 2 years. This indication is based on analyses of plasma HIV-1 RNA levels in controlled studies of ISENTRESS

(see CLINICAL TRIALS). The indication in paediatric patients is based on the evaluation of safety, tolerability, pharmacokinetic parameters and efficacy

of ISENTRESS through at least 24 weeks in a multicentre, open label, non-comparative study in HIV-1 infected, treatment-experienced children and

adolescents 2 to 18 years of age. The use of other active antiretroviral agents in combination with ISENTRESS is associated with a greater likelihood of

treatment response (see CLINICAL TRIALS). There are no study results demonstrating the effect of ISENTRESS on clinical progression of HIV-1

used for

ISENTRESS is used in combination

with other anti-HIV medicines to

treat adults, adolescents and children

2 years of age and older who are

infected with HIV. The children and

adolescents (2 - 18 years of age) who

participated in the ISENTRESS

studies had previously taken HIV


ISENTRESS belongs to a group of

medicines called integrase inhibitors.

It works by blocking HIV integrase,

one of the enzymes that is needed

during the replication process for

HIV to make more virus. When

integrase is blocked by ISENTRESS,

the virus is not able to reproduce

normally. This helps reduce the

amount of virus in the blood.

When used with other anti-HIV

medicines, ISENTRESS helps reduce

the amount of HIV virus in your

blood (called "viral load") and

increase the number of CD4 (T)


ISENTRESS may not have these

effects in all patients.

ISENTRESS does not cure HIV

infection or AIDS.

It is very important that you stay

under the care of your doctor during

How long to take it

Continue taking your medicine for

as long as your doctor tells you.

Do not change your dose or stop

taking ISENTRESS or your other

HIV medicines without first

talking with your doctor.

When your supply of ISENTRESS

starts to run low, get more from your

doctor or pharmacy. This is very

important because the amount of

virus in your blood may increase if

the medicine is stopped for even a

short period of time. HIV may



develop resistance to ISENTRESS

and become harder to treat.

If you forget to take it

If you miss a dose, take it as soon as

you remember. If you do not

remember until it is time for your

dose that you missed.

your doctor or pharmacist.

Like all medicines, ISENTRESS can

cause side effects, although not

everybody gets them.

In studies, side effects usually were

mild and did not cause patients to

common side effects are nausea,

headache, diarrhoea, tiredness

inflammation of the nasal passages

and throat, trouble sleeping and

upper respiratory tract infection,

cough, fever, bronchitis, back pain

and depression.

Additionally, since the medicine has

been on the market, the following

side effects have been reported:

depression, suicidal thoughts and

actions, low blood platelet count,

muscle tenderness or weakness,

clumsiness and lack of coordination,

rash with or without increase in some

white blood cells, severe skin

reactions, liver failure.

In some patients with advanced HIV

infection (AIDS), signs and

symptoms of inflammation from

opportunistic infections (eg:

pneumonia, tuberculosis or a painful

blistering rash known as shingles)

may occur when combination

antiretroviral treatment is started.

Tell your doctor immediately if you

notice any symptoms of infection.

Tell your doctor or pharmacist if

you develop any unusual side effect

or if any known side effect does not

go away or gets worse.
