Externa 2mg Syrup is a medicine given to children to help treat nausea and vomiting. It is mainly given to treat nausea and vomiting associated with surgery, chemotherapy, radiotherapy, and stomach/intestinal infection. It also helps treat vomiting that is caused as a side effect of medicines like painkillers.
Externa 2mg Syrup may be given before or after meals. To control vomiting caused due to chemotherapy, give this medicine to your child 30 minutes before the procedure. Give it 1 to 2 hours before a radiotherapy session and 1 hour before surgery to prevent your child from vomiting post these procedures. If your child expels out the medicine within 30 minutes of the intake, help your child calm down and repeat the dose. Do not double the dose if it is already time for the next dose.
Externa 2mg Syrup may cause some temporary side effects such as headache, constipation, diarrhea, and fatigue. These side effects usually subside once your child’s body adapts to the medicine. In case these side effects persist or become bothersome, do reach out to the doctor on a priority basis.
Let the doctor know about all the medicines your child is taking, including painkillers, antibiotics, or medicines taken to treat depression. Also, inform the doctor if your child has a history of liver problems, kidney malfunction, blockage in the gastrointestinal tract, heart problems, or allergies to any medicine, its ingredients, or a food product. This information is very important for dose alterations and for planning your child’s overall treatment.
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How to use Externa Syrup
Take this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Measure it with a measuring cup and take it by mouth. Shake well before use. Externa 2mg Syrup may be taken with or without food, but it is better to take it at a fixed time.
How Externa Syrup works
During radiotherapy, chemotherapy, abdominal infection, or any major surgeries, the dead cells in the body start releasing a chemical called serotonin directly into the blood. Later, this stimulates special centers in the body that are responsible for inducing vomiting in your child. Giving Externa 2mg Syrup just before the procedure helps block the effect of this chemical on vomiting centers of the brain and prevents vomiting.

What if my child takes too much Externa 2mg Syrup?
Externa 2mg Syrup is unlikely to cause harm if you give an extra dose by mistake. However, you must still speak to your child’s doctor immediately. Sometimes, excessive intake of Externa 2mg Syrup can cause some serious side effects like excess sleepiness, agitation, rapid heartbeat, hypertension, flushing, dilated pupils, sweating, involuntary muscle jerk, uncontrolled eye movements, overactive reflexes, and seizures. These symptoms are collectively known as serotonin syndrome. If any of these appear, consult the doctor without any delay.
How should Externa 2mg Syrup be stored?
Externa 2mg Syrup should be stored at room temperature, in a dry place, away from direct heat and light. Also, keep all the medicines out of the reach and sight of children to avoid any accidental intake.
What all medicines should my child avoid while taking Externa 2mg Syrup?
Usually, it is advised not to give Externa 2mg Syrup along with antidepressant medicines, apomorphine, anti-migraine medicines, painkillers, heart medicines, and antibiotics like linezolid. But, it is ideal to speak to your child’s doctor before coming to any conclusion. So, narrate your child’s complete medical history to your child’s doctor and follow their advice strictly.
In what conditions do I need to call my child’s doctor right away?
Call your child’s doctor immediately if your child develops symptoms of serotonin syndrome like irregular heartbeat, green-colored vomiting, inability to pass wind, pale skin and eyes, dark-colored urine, restlessness, and insomnia.
My child is having a migraine and is on medication. Can I give Externa 2mg Syrup along with it?
Avoid combining Externa 2mg Syrup with such medicines because concomitant use of Externa 2mg Syrup with medicines meant to treat depression or migraine results in serotonin syndrome. Consult your child’s doctor before giving any medicine to your child.
