Cough Syrup for Kids: What to Give, What to Avoid & Safe Dosage 

Introduction

Cough and cold are very common in children, especially during weather changes or when they catch infections from others¹. Most of the time, these coughs are mild and easily manageable at home. However, many people use cough syrups as the primary approach to manage cough in children. Though they can help relieve symptoms such as dry cough and mucus buildup, they are not always essential². This article explores different types of cough syrup for children, when they should be used, their side effects, recommended dose, easy ways to make cough syrups at home, and when to avoid them. 

What Is Cough Syrup?

Cough syrup is a liquid medicine that is often used to treat coughs. It acts differently depending on the ingredients; some cough syrups block the cough reflex, particularly in dry or unpleasant coughs, while others loosen and thin heavy mucus, allowing it to be coughed up more easily. This helps clean the airways and makes breathing easier³. 

Cough syrups can enhance sleep and overall comfort by lowering coughing or by helping in the removal of mucus in children. However, it is important to note that cough syrup does not cure the underlying sickness; rather, it relieves symptoms while the body heals⁴. 

Note: Persistent night coughing in children may sometimes indicate an underlying health condition such as asthma⁵. In such cases, the child should be evaluated by a doctor.  

Types of Cough Syrup in Children

Different types of cough syrups are available to help manage different kinds of coughs in children. The following are some of the most common types of cough syrups for kids: 

1. Antitussive Cough Syrups 

These are known as central cough suppressants. They work by acting on cough receptors in the brain and reducing the cough reflex. They are mainly used to treat dry, irritating coughs that do not produce mucus. They are especially helpful for frequent coughing. However, they are not routinely prescribed in children under the age of 2⁶.

2. Antihistamine Cough Syrups 

These are widely used to treat allergy symptoms caused by dust or pollen. They work by lowering the body’s allergic response, thereby alleviating symptoms such as sneezing, runny nose, and post-nasal drip. However, these are not recommended in children who have a general cough without a clear cause⁷. 

3. Expectorants 

These are known as the wet cough syrups. They are used to treat coughs that produce mucus or phlegm. They work by loosening the mucus in the lungs and making it easier to cough it out⁸. By clearing the airways, these syrups help improve breathing and provide relief from chest congestion. 

4. Decongestants 

These are the cough syrups that help relieve a blocked or stuffy nose by shrinking the swollen blood vessels inside the nose. Thus, by lowering swelling inside the nose, they help open the nasal passages and make breathing easier⁹.

Note: Cough syrups are not recommended for children under 2 years of age unless specifically prescribed by a doctor. For older children, cough syrup should only be used as advised by the doctor. Not all cough syrups are suitable for every child, as the right type depends on the cause of the cough. Therefore, avoid buying them over-the-counter. Also, avoid giving more than one cough or cold medicine at the same time unless a paediatrician recommends it. 

Homemade Cough Syrup for Kids

Mild cases of cough and cold can be managed at home using several home-care approaches. The following are some homemade cough syrups for kids: 

1. Ginger and Tulsi Cough Syrup 

• Preparation: Take a handful of tulsi (holy basil) leaves and a piece of crushed ginger. Boil these in a cup of water for about 10-15 minutes. Strain the mixture and add a little honey, if needed. 
• When to Use: Sore throat, cold, cough, allergy, and infection. 
• Benefits: Both ginger and tulsi are known to have anti-inflammatory properties. Hence, drinking this syrup might help reduce throat inflammation, reduce cough, and help relieve fever and cold^10,11.

2. Honey and Warm Water Cough Syrup 

• Preparation: This cough syrup mainly needs two ingredients, honey and warm water. Take half a glass of warm water and mix 1-2 teaspoons of honey into it. You can use it like that or add some crushed ginger if needed. 
• When to Use: Dry cough and sore throat. 
• Benefits: Honey is known for its soothing effect. It helps lower throat irritation and thus reduces the tendency to cough. It also has antioxidants, which might help fight infections¹². 

Note: Honey should not be given to children younger than one year old due to the risk of botulism (muscle weakness and paralysis from a type of bacterial infection). 

3. Turmeric and Black Pepper Syrup 

• Preparation: Take turmeric powder and black pepper, one teaspoon each. Boil both in half a cup of water for a few minutes. After cooling slightly, mix in 1 tablespoon of honey if needed. 
• When to Use: Dry cough, sore throat, and cold. 
• Benefits: It might help reduce irritation, mainly caused by a dry cough. It also helps to alleviate the symptoms of cold¹³.

4. Onion-Honey Syrup 

• Preparation: Take a small onion and crush it to extract its juice. Then add one teaspoon of honey to the juice and mix well¹³. 
• When to Use: Cough, cold, and allergies. 
• Benefits: Onion has anti-inflammatory properties which help in fighting infection and reducing respiratory irritation. Its natural components help reduce the irritation due to cough. It also reduces allergic responses causing cough or cold¹⁴.

5. Carom (Ajwain) Water Syrup 

• Preparation: Take a few ajwain seeds and boil them in a cup of water for 10 minutes, then strain it. 
• When to Use: Cough, cold, chest congestion. 
• Benefits: Ajwain seeds contain natural compounds like thymol and carvacrol that help fight germs and support immunity. They help reduce cough, loosen mucus, and clear blocked airways, making breathing easier. They can also soothe the airways and reduce irritation in the chest¹³. 

Note: The information provided is for general educational purposes and should not be used as a substitute for medical advice or treatment. Always consult a paediatrician before administering any homemade or herbal approach to children, particularly infants and toddlers. Also, if the child’s cough persists, worsens, or is accompanied by fever, difficulty breathing, wheezing, or chest pain, seek medical assistance right away. 

Recommended Dosage for Cough Syrup in Kids

There is no single standard dosage for cough syrup in children, as it depends on their age, weight, the type of medicine, and its concentration¹⁵. Most importantly, cough syrups should only be administered in the exact dose suggested by a doctor, since giving too little or too much may not be effective and can cause side effects¹⁶. 

Caretakers should never assume the dosage or give children adult formulations. To ensure exact dosing and prevent overdose, the FDA recommends using professional measuring equipment such as a medication cup, oral syringe, or dropper rather than household spoons¹⁷. 

Note: Following the prescription dosage recommended by a doctor is very important to avoid adverse events that can be caused by overdose. For any doubts, immediately reach out to a paediatrician. 

Side Effects of Cough Syrup in Children

Cough syrups for kids may sometimes cause side effects that affect different body systems, including the brain and digestive system and, in rare cases, more serious reactions. 

• Neurological Symptoms: These include drowsiness or excessive sleepiness, dizziness or light-headedness, irritability, etc. In severe cases, symptoms such as tremors (shaking), hallucinations, confusion, seizures, etc., can be caused. 
• Digestive Symptoms: These include nausea, vomiting, diarrhoea, constipation, stomach discomfort, etc. 
• Respiratory Symptoms: These include breathing difficulties, slow breathing, and rarely, irregular breathing patterns and apnoea (temporary stopping of breathing). 
• Heart-Related Symptoms: These include increased heart rate, irregular heartbeat, heart palpitations, etc. 
• Other Symptoms: Dry mouth and eyes, blurred vision, slight headache, etc¹⁸.

When to Avoid Cough Syrup?

According to the FDA and other health authorities, cough syrups are not recommended for children under the age of two, as they can cause several adverse effects in them¹⁶. They are also usually not necessary for mild or short-term coughs caused by common viral infections, which often resolve on their own without the need for medication¹. In many cases, giving syrup without first determining the actual reason for the cough (such as a cold, allergy, or asthma) might have no benefits over it⁷ and can even delay accurate diagnosis and treatment. 

These medicines should also be avoided when a child shows symptoms like wheezing, chest tightness, or difficulty breathing, as these may indicate more serious conditions that need medical attention rather than just cough relief. Using cough syrup in such situations may only mask the symptoms instead of treating the underlying problem⁵.

Another important reason to be cautious is the risk of side effects and overdose of the over-the-counter syrups. These may cause sleepiness, dizziness, nausea, and sometimes more serious reactions¹⁸. Taking more than the recommended dose or using multiple cold and cough syrups together can lead to repeated ingredients, which increases the risk of overdose and toxicity¹⁶.

When to Consult a Doctor?

Consulting a doctor is important in the following cases: 

• When the cough is accompanied by fever, difficulty breathing, wheezing, or chest pain  
• If the cough is affecting your child’s feeding or sleep 
• If symptoms worsen or do not improve even after 1-2 weeks of home care or using cough syrups¹
• If side effects (such as excessive drowsiness, seizure, breathlessness, allergic reactions) arise from using cough syrup^17,18 

Conclusion

Cough in children is usually harmless and improves with time and simple care. Cough syrups can help ease symptoms, but they should be used carefully and only when necessary. Understanding the type of cough, selecting the appropriate medicine, and maintaining proper dosage is critical for a child’s safety. 

In many cases, basic home medicines and supportive care are sufficient to assist them in recovering peacefully. However, parents should avoid self-medication and always seek a paediatrician’s advice, especially for young children.
