Eamonn Brady MPSI looks at some of the common back-to-school issues and how the pharmacist can help

In this article, I discuss five distinct subjects relating to children’s health that pharmacists encounter regularly, some all-year-round and some more so after children go back to school. I discuss:

  • Children’s diet.
  • Back-to-school anxiety.
  • Head lice.
  • Threadworm.
  • Conjunctivitis.

Children’s diet

Different nutrients are needed for a balanced diet. Nutrients are made up of macronutrients (big), which are essentially carbohydrates, fats and proteins; and micronutrients (small), which are vitamins and minerals. Different foods have different micronutrients and macronutrients.


Staying hydrated is important to ensure all our nutrients are absorbed properly. Dehydration causes fatigue and lack of concentration. We should aim to drink about six-to-eight glasses of water per day to stop us getting dehydrated. Water can also be obtained through diet ie, soups.

Fruit and vegetables

Fruit and vegetables are packed with different vitamins and minerals (micro), which are all essential in different ways (see figures 1 & 2). Fruit and vegetables are also a good source of dietary fibre, which is important for our digestive health and regulates bowl movements. Including more fruit and vegetables as part of a balanced diet will help children grow and develop, improve vitality, and help prevent a range of chronic diseases, such as type 2 diabetes, heart disease, high blood pressure and cancer in later life.

It can be difficult to get some kids to eat the recommended ‘five a day’ of fruit and veg. Research has shown that the more fruit and vegetables are available and easily accessible for children, the more likely they are to eat them. Therefore, if fruit is chopped-up and ready to eat, children will eat more of them.

Providing a variety of different fruits and vegetables is one way to encourage children towards healthy eating habits, however, be patient. There is some evidence that children need to try new fruits and vegetables up to eight or nine times before they are liked or accepted. Being creative in the way fruit and vegetables are served-up can help. For example, prepare vegetables in different ways to vary the texture, such as raw, microwaved, mashed, baked, and grated into a casserole, blended-up as a pasta sauce or as a soup.


Carbohydrates are made up of sugars. They are for energy. Refined sugars include sweets, cakes, etc. They have no nutritional benefits and should only be consumed sparingly, as they can cause serious health problems for adults and children, including tooth decay, diabetes, and heart disease. Wholegrain carbohydrates are the more nutritious option as opposed to wheat, ie, white bread. Wholegrains contain soluble fibre, vitamin, iron, copper, zinc, magnesium and antioxidants.


Proteins are made up of essential and non-essential amino acids. Non-essential amino acids are already made in the body, so we do not need them from our diet; on the other hand, essential amino acids are the proteins we need to ingest. All these proteins (amino acids) help each other for the growth and repair of the body’s cells. Children need about 20-to-35 grams of protein in a day, depending on weight, age, and gender, ie, a tablespoon of peanut butter is about 5gs protein, and a palmed-sized portion of meat is about 20 grams. Other examples of foods high in protein are eggs, cheese, nuts, seeds and poultry, etc.


Fish oil is recommended for a healthy diet because it contains the omega-3 fatty acids eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). EPA aids emotional health and reduces stress levels, while DHA aids memory and concentration, therefore they are essential for children. Children should eat at least two portions a week of fish; one of the weekly portions (140g) should be oily fish, ie, salmon, mackerel.


Fats can either be saturated or unsaturated. Unsaturated are ‘good’ fats (nuts and seeds), while saturated are considered ‘bad’ (ie, butter, fatty meat like sausages). Small amounts of fat are essential for body insulation but too much can lead to obesity and other serious health conditions later in life. High-fat diets for children tend to lead to greater fatigue, sleepiness and distraction. Chicken, tuna, lean beef and eggs are examples of healthy options that are high in protein and low in fat.


It is important for children and young people to get enough exercise for their mental and physical health. Kids and teens should get one hour or more of moderate-to-vigorous activity daily. Exercise can improve their social skills, self-esteem, academic scores, concentration and build stronger heart and bones.

School lunches:
The good and the bad

Making up school lunches for children can be challenging; it includes balancing the need to get children to eat healthy foods, making sure they are not hungry, and ensuring they have the right foods to keep their concentration level up throughout their school day.

Why is the contents of the lunchbox so important?

  • Childhood obesity is on the rise. Irish children as young as seven are wearing adult-sized uniforms to school and it has come to light that one-in-five children are classified as obese. Obesity-related diseases like type 2 diabetes are on the rise.
  • Children need to know the difference between healthy food and unhealthy food — what is a ‘treat food’ and what foods are vital for health. By avoiding unhealthy foods in lunchboxes, we are sending the message that foods like fruit, vegetables, brown bread, and yoghurts are better for you than chocolate bars and crisps.
  • Deficiencies are avoided by including a range of different foods in the child’s lunchbox, from fish, to vegetables, wholegrain, fruit, and dairy.

What should go into a healthy lunchbox?

A kid’s lunchbox should be low in fat, salt, and high in essential vitamins, minerals, and nutrients. All meals prepared for children should help maintain normal growth and development, whether it be breakfast, lunch, dinner, or snacks. They should be fibre-rich (to avoid constipation), full of fruit and vegetables, contain a dairy option, and have lean protein.

Children’s back-to-school anxiety

Feeling anxious is completely normal for children, teens and parents while returning to school and/or starting a new school. Uncertainties over Covid-19 and its impact on young people over the last 18 months has heightened anxieties for many. Feeling anxious is the mind and body’s natural reaction to stress and fear, ie, ‘fight or flight’. It is essentially the fear of the unknown. Symptoms may include restlessness, nervousness, feelings of danger, panic and stomach upset. These feelings of anxiety only become a problem if these fears become overwhelming or unmanageable. This can be an anxiety disorder.

Within days of returning to school, an anxious child may be clingy, angry, complain of stomach pains and headaches, or be quiet and emotional. Children and young people have different worries relating to school, such as teachers, being away from their parents, friends, and fitting in. If a child does not go to school because of these feelings, they cannot find out if their fears are irrational or not.

If a child is excessively complaining of prolonged headaches, tummy complaints and other symptoms of anxiety, they may need a medical assessment. Do not rule out other underlying conditions if these complaints are a constant. Getting children into a school sleep routine before school starts can also reduce the amount of anxiety and stress they may be feeling.

Tip 1: Listen

Simply listening to a child’s fears about returning can make a child feel more at ease and secure. It will give him/her confidence in dealing with these thoughts about difficult times. Dismissing fears, ie, ‘you’ll be fine, nothing to worry about’ generally will not help. Children often want to talk about worries without a parent ‘fixing’ them. They usually seek validation and confidence from a parent or guardian.

Tip 2: The basics

Children can cope better with everything if they are getting enough sleep, eating regular healthy meals and snacks and getting daily exercise. A healthy body can mean a healthy mind.

Tip 3: Action plan

Worried teens and children may have scattered thoughts, so making coping methods for them can be helpful — for example, asking them ways in which they can react in a situation that is bothering them. A plan will help them to distinguish between rational or irrational situations (real and imaginary scenes in their heads).

Tip 4: Positivity

Everyone needs positivity. Once these fears are addressed and coping methods are in order, there is no need to dwell on them. Focusing on the positives of school can ease a child’s anxiety, ie, ‘what are you excited about on your first day?’ Fun aspects can get overlooked by worries.

Tip 5: Parent behaviour   

It is daunting for parents leaving their children at a new school for their first day. Children can see the stress and anxiety their parent displays. The calmer and more confident a parent is, the easier it will be for the child. It is important to be supportive, but also firm. A parent sharing their own anxieties with a child might not be a great decision if the child is anxious.

Head lice

Head lice is common as children return to school. The lice are small insects that feed on blood obtained by biting the scalp. These bites tend to be itchy, and this itchiness is caused by an allergy to the lice. Head lice are transferred by close hair-to-hair contact. They cannot jump, fly or swim, but rather walk from one hair to another. Head lice infestation is not as a result of dirty hair and poor hygiene. Head lice can be found in all hair types, long or short, and in hair of any condition.


There is no way of guaranteeing a child will not get head lice, but checking a child and the whole family’s hair and scalp regularly is important. If a child has long hair, tie it back, as this helps to reduce the likelihood of contact between their hair and that of an infected child.

There are many products to treat head lice, some of which include:

  1. Hedrin® Once Spray Gel and Shampoo.
  2. Full Marks® Solution.
  3. Lyclear® Products.

If parents do not wish to use chemicals, wet-combing is another method of removing head lice. Nit combs are used for wet combing. The steps to follow for wet-combing are to wash the hair as normal using an ordinary shampoo, apply conditioner liberally to wet hair (this causes lice to lose their grip on hair), and comb the hair through with a normal comb first.

Then with a fine-tooth nit comb, comb from the roots along the complete length of the hair and after each stroke, check the comb for lice and wipe it clean. Work methodically over the whole head for at least 30 minutes. Rinse the hair as normal. Repeat every three days for at least two weeks.


Threadworms are tiny parasites that infect the large intestine. They are mostly common in children under the age of 10 years. A common symptom includes intense itching around the anus, especially at night. If it is suspected a child has threadworms, the entire family should be treated, as sometimes they can be asymptomatic.


Threadworms are usually passed on through poor hygiene. The female worms lay eggs around the anus. When a child scratches, the threadworms can be transferred from their fingers to their mouth and different surfaces. If another person touches these contaminated surfaces and then their mouth, they become infected with threadworms. Therefore, the prevention of threadworms includes keeping a high standard of hygiene, ie, frequent hand-washing and avoid scratching the area.


Hygiene method: This can be used to stop the threadworm infection. These methods should be followed for six weeks. Everyone in the house must follow the strict methods. Some of this method includes washing all bed linen, clothes, thoroughly vacuum and dust the house, disinfect bathrooms and kitchen, keep fingernails short, no nail-biting, wash hands frequently, clean toothbrushes thoroughly before use, shower regularly and avoid towel-sharing.

Medication: There is a 75 per cent chance that everyone in the family will be infected with threadworms if one person has it. The most common medications are mebendazole and piperazine. Mebendazole (Vermox®) is the preferred treatment for those over two years of age.

It prevents the threadworms from absorbing glucose. It kills the worms in the gut, but not the eggs that have been laid around the anus. These can stay on underwear and bed linen, so it is important to have good hygiene standards in the house. Re-infection can be common, so another dose can be useful after two weeks of the initial treatment.


Conjunctivitis is when the eyes become inflamed, more commonly from a virus than bacteria. Symptoms usually clear-up within two weeks. The main symptom to look out for is red or pink eyes, green discharge, and swollen and itchy eyes. If there is pain and both eyes are red for more than two days, it may be a bacterial infection and the child needs to see his/her GP. If the child has sticky eyes for two weeks, they also need to see their GP.


Both viral (most common) and bacterial conjunctivitis are highly contagious, so good hygiene standards can prevent the contamination and spread of conjunctivitis. Make sure they wash their hands often, do not let them rub their eyes (if they do, wash their hands after touching their eyes), and do not share pillows and towels.


Viral conjunctivitis: There is no medication to treat a viral infection. There are ways to ease their discomfort, which includes (1) wash hands; (2) wet a cotton ball or pad with cooled boiled water; (3) wipe the child’s eye from the inner to outer corner. Make sure to use a different cotton ball or pad each time; (4) dry the eyes, using a different cotton ball or pad; and (5) wash hands.

Bacterial conjunctivitis: The doctor may prescribe antibiotic eye-drops; the pharmacist can decide if OTC options
are warranted and when referral to a GP is required. The HSE has stated that there is no reason for a child to be out of school because of viral conjunctivitis, unless they feel sick. It is important to inform the childcare provider if a child has conjunctivitis.
