6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor if you are pregnant or intend to become pregnant.
Your doctor will discuss the risks and benefits of taking ZACTIN during pregnancy.
When taken during pregnancy, particularly in the last 3 months, medicines like ZACTIN
may affect your newborn baby and they may experience irritability, constant crying,
feeding difficulties, vomiting, fluctuating temperature, seizures or fits, tremors,
jitteriness, bluish appearance (cyanosis), breathing interruptions, low blood sugar,
muscle stiffness, muscle weakness or over-responsive reflexes. These symptoms are
uncommon and may be due to either the effect or discontinuation of ZACTIN.
When used during pregnancy, particularly in late pregnancy, medicines like ZACTIN
may increase the risk of a serious condition in babies called persistent pulmonary
hypertension (PPHN) which may cause the baby to breathe faster and appear bluish.
If this happens to your baby, you should contact your doctor and/or go straight to
the Emergency Department at your nearest hospital.
If you take ZACTIN near the end of your pregnancy, there may be an increased risk
of heavy vaginal bleeding shortly after birth, especially if you have a history of
bleeding disorders. Tell your doctor or midwife that you are taking ZACTIN so they
can advise you.

Like many other medicines, ZACTIN can pass into breast milk. Your doctor will discuss

4. How do I use ZACTIN?
How much to take
The usual starting dose is one capsule taken once a day in the morning. Your doctor
may change your dose depending on how you respond to the medicine.
Follow the instructions provided and use ZACTIN until your doctor tells you to stop.
When to take ZACTIN
ZACTIN should be taken as a single dose in the morning. If your doctor tells you to
take it twice a day, take a dose in the morning and at noon.
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you
remember when to take it.
How to take ZACTIN
Swallow the capsules whole with a glass of water.
ZACTIN can be taken with or without food.
How long to take ZACTIN
Continue taking ZACTIN for as long as your doctor tells you to.
The length of treatment with ZACTIN will depend on how quickly your symptoms improve.
Most medicines of this type take time to work so don't be discouraged if you do not
feel better right away. While some symptoms will be relieved sooner than others, ZACTIN
commonly takes two to four weeks before improvement is really apparent.
If you do not start to feel better in about four weeks, check with your doctor.
If you forget to take ZACTIN
If it is almost time for your next dose, skip the dose you missed and take your next
dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking
your medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some
hints.
If you use too much ZACTIN
If you think that you have used too much ZACTIN, you may need urgent medical attention.
You should immediately:
phone the Poisons Information Centre
(Australia telephone 13 11 26) for advice, or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
If you have taken too much ZACTIN, you may feel sick in the stomach, vomit, feel restless,
agitated or excited.
5. What should I know while using ZACTIN?
Things you should do
Persons taking ZACTIN may be more likely to think about killing themselves or actually
trying to do so, especially when ZACTIN is first started or the dose is changed. Tell
your doctor immediately if you have any suicidal thoughts or other mental/mood changes.
Occasionally, the symptoms of depression or other psychiatric conditions may include
thoughts of harming yourself or committing suicide. These symptoms may continue or
get worse during the first one to two months of treatment until the full antidepressant
effect of the medicine becomes apparent. This is more likely to occur in children,
adolescents and young adults under 25 years of age.
Contact your doctor or a mental health professional immediately or go to the nearest
hospital for treatment if you or someone you know is demonstrating any of the following
warning signs:
worsening of your depression
thoughts or talk about death or suicide
thoughts or talk of self-harm or harm to others
any recent attempts at self-harm
increase in aggressive behaviour, irritability or any other unusual changes in mood
or behaviour
All mentions of suicide or violence must be taken seriously.

that you are taking ZACTIN.

taking ZACTIN.
Tell your doctor immediately if you become pregnant while taking ZACTIN.
Your doctor will discuss the risks and benefits of taking ZACTIN during pregnancy.

anxiety, irritability, agitation, confusion, weakness, headache, feeling sick, or
tingling or numbness of the hands or feet. Your doctor may want you to gradually reduce
the amount of ZACTIN you are taking before stopping completely.
Do not take the herbal remedy St John's Wort (Hypericum perforatum) while you are
being treated with ZACTIN.

doctor at your next visit.
