Your child’s medicine at a glance
Aristocillin 100mg Drop works best on an empty stomach, so try to give it to your child 30 minutes to 1 hour before he/she eats. However, give it with food if it upsets your child’s stomach. It is generally given three times a day. Stick to the dose, time, and way prescribed by the doctor as these depend on the severity of the infection, its type, and your child’s body weight and age. If your child vomits within 30 minutes of taking the medicine, repeat the dose when your child feels better. However, do not double the dose if it is the time for the next dose.
Aristocillin 100mg Drop can cause some minor and temporary side effects such as nausea, vomiting, diarrhea, abdominal pain, and mild skin rash. These side effects should ideally subside on their own. But, in case these side effects persist or become bothersome for your child, report to the doctor without a delay.
Tell your child’s doctor if your child has had any previous episode of allergy, heart problem, blood disorder, birth defects, airway obstruction, lung anomaly, gastrointestinal problem, skin disorder, and kidney malfunction. Knowledge of your child’s medical history will help the dose make dose alterations and plan your child’s overall treatment.

How Aristocillin Drop works
Aristocillin 100mg Drop is an antibiotic. It works by preventing the formation of the bacterial protective covering (cell wall) which is essential for the survival of the bacteria. By doing so, this medicine kills the infection-causing bacteria and prevents the infection from spreading without making them resistant to further treatment.
Quick tips
- Complete the entire course of antibiotics without stopping the medicine in between. Doing so may cause the bacteria to multiply again, become resistant, or cause another infection.
- Make sure your child drinks plenty of water if they develop diarrhea as a side effect.
- Conditions like common cold and flu are caused by viruses. Never use this medicine for such conditions.
- Give Aristocillin 100mg Drop to your child only for their current infection. Avoid storing the medicine for future use as it is impossible to judge whether the same medicine would work for any future illnesses.
- Stop this medicine and immediately report to your child’s doctor in case your child develops an itchy rash, facial swelling, or breathing difficulties while taking this medicine.
- Aristocillin 100mg Drop is used to treat infections caused by bacteria.
- Finish the prescribed course, even if you start to feel better. Stopping it early may make the infection come back and harder to treat.
- Diarrhea may occur as a side effect. Taking probiotics along with Aristocillin 100mg Drop may help. Talk to your doctor if you notice bloody stools or develop abdominal cramps.
- Take it with food and plenty of fluids to avoid an upset stomach.
- Stop taking this medicine and inform your doctor immediately if you develop an itchy rash, swelling of the face, throat or tongue or breathing difficulties while taking it.

Frequently asked questions
Giving your child Aristocillin 100mg Drop for a long term can cause fungal infection (oral thrush) in the mouth and severe gastrointestinal infections (superinfections). Therefore, do not alter the dose and duration on your own and give Aristocillin 100mg Drop to your child exactly as prescribed. Additionally, irregular treatment, repeated use, and misuse of Aristocillin 100mg Drop can make the bacteria resistant.
Although rare, Aristocillin 100mg Drop may cause some serious side effects such as skin rash, allergy, superinfection, bleeding problems, seizures, and blood cell abnormalities. If your child experiences any such symptoms, consult the doctor at the earliest.
Aristocillin 100mg Drop can sometimes interact with other medicines or substances. Tell your doctor about any other medicines your child is taking before starting Aristocillin 100mg Drop. Also, check with your child’s doctor before giving any medicine to your child.
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.
In the common cold, the mucus changes its color and thickens up with time, but this does not mean that your child needs antibiotics. Common cold symptoms often last for 7-10 days. In case they fail to clear up within this duration, reach out to your child’s doctor for guidance.
