Warnings and precautions
During treatment with these types of medications, it is important that you and your doctor have good ongoing communication about how you are feeling.
Dom-FLUOXETINE is not for use in children under 18 years of age.
New or Worsened Emotional or Behavioural Problems
Particularly in the first few weeks or when doses are
adjusted, a small number of patients taking drugs of this type
may feel worse instead of better. They may experience new
or worsened feelings of agitation, hostility, anxiety,
impulsivity, or thoughts about suicide, self-harm or harm to
others. Suicidal thoughts and actions can occur in any age
group but may be more likely in patients 18 to 24 years old.
Should this happen to you or those in your care, consult
your doctor immediately. Close observation by a doctor is
necessary in this situation. Do not discontinue your
medication on your own.
You may be more likely to think like this if you have previously had thoughts about harming yourself.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Dom-FLUOXETINE has an effect on the electrical
activity of the heart
In very rare cases, this effect can lead to disturbances in
heart rhythm. These heart rhythm disturbances are more
likely in patients with risk factors, such as heart disease, or in
the presence of certain drugs. In general, females and people
more than 65 years in age are at higher risk. It is important to
follow the instructions of your doctor with regard to dosing.
If you experience any symptoms of a possible heart rhythm
disturbance, such as dizziness, palpitations (sensation of
rapid, pounding, or irregular heart beat), fainting, or seizures,
you should seek immediate medical attention.
Before starting Dom-FLUOXETINE, tell your doctor or pharmacists:
- if you have ever had an allergic reaction to any medication
- if you have QT/QTc prolongation or a family history of QT/QTc prolongation;
- if you have a heart disease;
- if you have a personal history of fainting spells;
- if you have a family history of sudden cardiac death at <50 years;
- if you have electrolyte disturbances (e.g., low blood potassium or magnesium levels) or conditions that could lead to electrolyte disturbances (e.g., vomiting, diarrhea, dehydration);
- if you use diuretics, enemas and/or laxatives;
- all your medical conditions, including a history of liver or kidney problems, seizures or blackouts, diabetes, bleeding disorder or have been told that you have low platelets, glaucoma or increased pressure in the eyes, eye pain, or blurred vision;
- if you had a recent bone fracture or were told you have osteoporosis or risk factors for osteoporosis.
- any medications (prescription or nonprescription) you are taking or have recently taken, especially monoamine oxidase (MAO) inhibitors (e.g., phenelzine sulfate, tranylcypromine sulfate, moclobemide or selegeline) or thioridazine or anticoagulants, acetylsalicylic acid ( ASA) and other non-steroidal anti-inflammatory drugs (e.g., ibuprofen);
- any natural or herbal products you are taking (e.g. St. John's Wort);
- if you are pregnant or thinking about becoming pregnant, or if you are breast feeding;
- your habits of alcohol and /or street drug consumption
- if you drive a vehicle or perform hazardous tasks during your work.
Angle-closure Glaucoma
Dom-FLUOXTINE can cause an acute attack of glaucoma. Having your eyes examined before you take Dom-FLUOXETINE could help identify if you are at risk of having angle-closure glaucoma. Seek immediate medical attention if you experience:
- eye pain
- changes in vision
- swelling or redness in or around the eye
Effects on Pregnancy and Newborns
If you are already taking Dom-FLUOXETINE and have just
found out that you are pregnant, you should talk to your doctor
as soon as possible.
Taking Dom-FLUOXETINE in early stages of pregnancy:
Some studies have suggested a small increased risk of birth
defects affecting the heart in babies whose mothers took Dom-
FLUOXETINE during the first few months of pregnancy. In
the general population, about 1 in 100 babies are born with a
heart defect. The studies found that this increased to about 2 in
100 babies whose mothers took Dom-FLUOXETINE during
early pregnancy.
Taking Dom-FLUOXETINE in later stages of pregnancy:
Possible complications at birth (from taking any newer
antidepressant, including Dom-FLUOXETINE):
Post-marketing reports indicate that some newborns whose
mothers took an SSRI (selective serotonin reuptake inhibitor)
or other newer anti-depressant during pregnancy have
developed complications at birth requiring prolonged
hospitalization, breathing support and tube feeding. Reported
symptoms included feeding and/or breathing difficulties,
seizures, tense or overly relaxed muscles, jitteriness and
constant crying.
In most cases, the newer anti-depressant was taken during the third trimester of pregnancy. These symptoms are consistent with either a direct adverse effect of the anti-depressant on the baby, or possibly a discontinuation syndrome caused by sudden withdrawal from the drug. These symptoms normally resolve over time. However, if your baby experiences any of these symptoms, contact your doctor as soon as you can.
Persistent Pulmonary Hypertension (PPHN) and newer
antidepressants:
The use of SSRIs, including Dom-FLUOXETINE, during
late pregnancy, may increase the risk of a serious lung
condition called persistent pulmonary hypertension of the
newborn (PPHN) that causes breathing difficulties in
newborns soon after birth. In the general population, PPHN
is known to occur in about 1 or 2 per 1000 newborns but this
may be increased 2 to 6 times in babies whose mothers used
SSRIs during late pregnancy.
If you are pregnant and taking an SSRI, or other newer antidepressant, you should discuss the risks and benefits of the various treatment options with your doctor. It is very important that you do NOT stop taking these medications without first consulting your doctor. See SIDE EFFECTS AND WHAT TO DO ABOUT THEM section for more information.
Taking Dom-FLUOXETINE may increase your risk of breaking a bone if you are elderly or have osteoporosis or have other major risk factors for breaking a bone. You should take extra care to avoid falls especially if you get dizzy or have low blood pressure.

This medicine has been prescribed only for you. Do not
give it to anybody else, as they may experience undesirable
effects, which may be serious.

Overdose
Side effects and what to do about them
Like other medications, Dom-FLUOXETINE can cause some
side effects. You may not experience any of them. For most
patients, side effects are likely to be minor and temporary.
However, some may be serious. Some of these side effects
may be dose related. Consult your doctor if you experience
these or other side effects, as the dose may have to be
adjusted.
The most common side effects of Dom-FLUOXETINE are:
- nausea
- dizziness
- headache
- anxiety
- nervousness
- drowsiness
- insomnia (difficulty falling or staying asleep)
- fatigue
- weakness
- diarrhea
- upset stomach
- dry mouth
- loss of appetite
- excessive sweating
Dom-FLUOXETINE does not usually affect people’s normal activities. However, some people feel sleepy while taking it, in which case they should not drive or operate machinery.
Although psychiatric disorders may be associated with decreases in sexual desire, performance and satisfaction, treatment with this medication may also affect sexual functioning. Occasionally, these symptoms may continue after stopping Dom-FLUOXETINE.
Dom-FLUOXETINE can raise your levels of a hormone
called “prolactin” (measured with a blood test). Symptoms of
high prolactin may include:
In men: breast swelling, difficulty in getting or maintaining
erections, or other sexual dysfunction.
In women: breast discomfort, leakage of milk from the
breasts, missed menstrual periods, or other problems with
your cycle.
If you experience any symptoms of a possible heart rhythm disturbance, such as dizziness, palpitations, fainting or seizures, you should seek immediate medical attention.
Discontinuation Symptoms
Contact your doctor before stopping or reducing your dosage
of Dom-FLUOXETINE. Symptoms such as headache,
insomnia, paresthesias (numbness, tingling, burning, or
prickling sensation) nervousness, anxiety, nausea, sweating,
dizziness, jitteriness and weakness and other symptoms have
been reported after stopping Dom-FLUOXETINE. These
symptoms usually disappear without needing treatment. Tell
your doctor immediately if you have these or any other
symptoms. Your doctor may adjust the dosage of Dom-
FLUOXETINE to alleviate the symptoms. See WARNINGS
AND PRECAUTIONS section for more information.
Effects on Newborns
Some newborns whose mothers took an SSRI (Selective
Serotonin Uptake Inhibitor) or other newer antidepressants
during pregnancy have shown such symptoms as breathing and feeding difficulties, jitteriness and constant crying. If your baby experiences any of these symptoms, contact your doctor
as soon as you can. See WARNING AND PRECAUTIONS
section for more information.
