Your child’s medicine at a glance

Genogyl N 150mg/100mg Suspension is an antibiotic medicine that is effective against a wide range of bacterial and parasitic infections. In children, it is used to treat infections of the urinary and gastrointestinal tract.

Give Genogyl N 150mg/100mg Suspension to your child orally, with food, preferably at a fixed time. Giving it with food helps prevent the risk of developing a stomach upset. Always give the dose as prescribed by the doctor since that depends on the severity and type of infection, body weight, and age of your child. If your child vomits within 30 minutes of intake, repeat the same dose but never double up the dose if it is time for the next dose.

Some children may develop minor and temporary side effects after taking Genogyl N 150mg/100mg Suspension. These include nausea, vomiting, metallic taste, headache, loss of appetite, abdominal cramps, red-brown urine, and mild skin rash. These side effects usually go away once your child’s body adapts to the medicine. However, in case they persist for long or start bothering your child, you must consult your child’s doctor without any delay.

Your child’s doctor must be aware if your child has ever had any previous episode of allergy, heart problem, blood disorder, liver impairment, and kidney malfunction. This will guide the doctor in planning your child’s overall treatment.

Q. My child is having a genetic deficiency of the G6PD enzyme. Is it safe to give Genogyl N 150mg/100mg Suspension?

It is advised that you get your child’s G6PD deficiency evaluated before starting the course of treatment. Avoid giving Genogyl N 150mg/100mg Suspension as deficiency of G6PD enzymes can lead to breaking of blood cells resulting in severe anemia.

Q. What if I give excess Genogyl N 150mg/100mg Suspension by mistake?

An extra dose of Genogyl N 150mg/100mg Suspension is unlikely to cause any harm. But, you must still be vigilant because overdose increases the risk of unwanted side effects such as seizures, tremors, severe headache, sudden weakness, blood cell abnormalities, and rapid and irregular heartbeat. Rush to your child’s doctor on an immediate basis if you notice any of these symptoms. If you think you have given too much Genogyl N 150mg/100mg Suspension to your child, immediately speak to a doctor.

Q. What should I do if my child shows no improvement even after taking Genogyl N 150mg/100mg Suspension for the prescribed duration?

Speak to your child’s doctor if your child does not show any improvement even after completing the dose. It could mean that the medicine is not able to act against the infection-causing microorganism. Your child’s doctor may change Genogyl N 150mg/100mg Suspension and prescribe some other antibiotic that is known to have a stronger impact on the infection-causing microorganism.

Q. Can other medicines be given at the same time as Genogyl N 150mg/100mg Suspension?

Genogyl N 150mg/100mg Suspension can sometimes interact with other medicines or substances. Tell your doctor about any other medicines your child is taking before starting Genogyl N 150mg/100mg Suspension. Also, check with your child’s doctor before giving any medicine to your child.

Q. Can I get my child vaccinated while on treatment with Genogyl N 150mg/100mg Suspension?

Antibiotics usually do not interfere with the ingredients in vaccines or cause a bad reaction in a child who has just been vaccinated. However, children taking antibiotics should not get vaccinated until they recover from the illness. As soon as your child feels better, the vaccine can be given.

Q. What should I tell the doctor before giving Genogyl N 150mg/100mg Suspension to my child?

Inform the doctor if your child is suffering from heart disease, genetic disorders involving blood vessels, seizures, psychiatric disorders, diabetes, photoallergy (allergy from sunlight), neuromuscular disorders, or rheumatoid arthritis.
