An allergy is a negative reaction of a person’s immune system to a particular substance, such as pollen, dust, mold, mites, pet dander, or food. These triggers can release histamine and other chemicals that cause allergy symptoms (1).

Allergies can be countered with medications, and allergy medications for children come in syrup, chewable tablets, or spray forms.

It is advisable to consult a pediatrician to learn about the types and forms of allergic medications most suitable for your child as medication concentration and dosage may differ for a two-year-old and an eight-year-old (2).

Read this post to learn more about the different types of allergy medicines for kids.

At What Age Can A Child Take Allergy Medicines?

Most over-the-counter allergy medicines are suitable for a child aged above two years. However, consulting a pediatrician for a prescription is highly recommended. Your healthcare provider would suggest the dosage of allergy medications and the form of medicine based on your child’s requirements (3).

Infants rarely catch allergies. But if you notice allergy symptoms in a child aged less than two years, consult your doctor (1).

Allergy Medicines For Kids

Allergy medicines for children are often similar to those prescribed for adults. But they may differ in their concentrations and mode of intake. Generally, they have low concentrations of active ingredients and are mostly available as syrups or chewable tablets.

Here are some child-friendly allergy drugs available on the market.

1. Antihistamines

Antihistamines are the most common medications administered for allergies in children. On contact with an outdoor or indoor allergen, the mast cells in our body release histamines. These histamines are the primary cause of most allergy symptoms, such as congestion, itchy nose, and runny eyes. Antihistamines reduce the impact of the already-produced histamines.

Antihistamines are classified into two types, namely sedating or first-generation and non-sedating or second-generation. Second-generation forms are the most child-friendly version. Due to their low sedative nature, they don’t hinder your child’s day-to-day activities. Some common second-generation counter antihistamines suggested by pediatricians for children include cetirizine, fexofenadine, and loratadine. These are also available in syrup, pill, eye drop, and chewable forms (4) (5).

Antihistamines can be given to children even before the allergy season begins as a preventive measure. Consult your health care professional for the dosage and the type of formulation (6).

Side effects: First-generation antihistamines, such as diphenhydramine, may cause drowsiness or hyperactivity. Also, a long-term dosage of second-generation antihistamines may lead to headache, nausea, and vomiting (2) (5).

2. Decongestants

A decongestant narrows the blood vessels and clears a stuffy nose caused by allergies. These medications are available as both over-the-counter and prescription drugs. And, some medications may also combine an antihistamine and a decongestant for improved performance (7).

Decongestants are present in the form of nasal sprays, nose drops, tablets, and syrups. Oxymetazoline, phenylephrine, and pseudoephedrine are the common decongestants.

Remember that decongestants only relieve the symptom of a blocked nose and act on the primary cause; thus, they are only ideal for short-term relief (8) (9).

Side effects: Decongestants are addictive, and excessive use could have a rebound effect—they could worsen nasal congestion. They may also lead to insomnia, anxiety, hallucinations, and increased heart rate (8).

3. Cromolyn sodium

Cromolyn sodium is a medication that is effective against nasal allergic reactions. By acting on the mast cells, cromolyn sodium reduces the production of inflammatory chemicals, such as histamine, and helps alleviate nasal allergy symptoms such as runny nose, itching, and sneezing (10).

It is mostly available as an over-the-counter nasal spray. Although cromolyn sodium reduces the release of antihistamines, it has no impact on histamines already in circulation; therefore, it is not the primary source of treatment for pollen allergies or hay fever.

Cromolyn sodium is better used as a preparatory medication as the allergy season approaches or before contact with a common allergen. Based on your child’s contact with potential indoor or outdoor allergens, your pediatric allergist may suggest the child use it three to five times a day.

Side effects: As cromolyn sodium is a nasal spray, it may irritate and cause a burning and stinging sensation immediately after usage. It may also cause sinus pain and nose bleeds. Avoid using the spray and contact your doctor immediately if the side effects persist.

4. Corticosteroids

A pediatrician may recommend corticosteroids or steroids for asthma or allergic rhinitis attacks. They can be administered orally as pills and syrups or via the nose as steroid nasal sprays. Steroids either act on the inflamed cells when taken orally or directly on the site of inflammation (11).

Corticosteroids can be used for both short-term and long-term allergic reactions and a range of allergies. Nasal steroids are also used to reduce congestion, but they are mostly slow-acting, and hence, not ideal for immediate allergy relief. Your pediatrician may prescribe them before the allergy season begins and may ask your child to continue their usage the entire season based on their susceptibility rate.

Prednisolone is a common corticosteroid administered to children. Corticosteroids are available as over-the-counter medications. Nevertheless, it is better to consult a pediatrician for the dosage level and type of steroid to be used (12).

Side effects: Corticosteroids may reduce the growth rate of a child temporarily. They may also lead to weight gain, rounding of the face, mood swings, and cataracts (12).

5. Eye drops

Most eye drops you find in the allergy medicine aisle are antihistamines with a combination of mast cell stabilizers. These eye drops reduce irritation triggered by weed pollens, grass pollen, and other allergens that have entered your child’s eyes. Sometimes, your pediatrician may also suggest nonsteroidal anti-inflammatory eye drops (13) (14).

Ketotifen is the most commonly prescribed antihistamine eye drops for children above three years. Eye drops are safe to be used throughout the pollen season.

Side effects: They may initially cause a burning sensation during usage. If the sensation persists, stop the usage and contact your medical supervisor. Antihistamine eye drops may also cause eye dryness.

As most allergy medicines for children are available over the counter, it is always a good idea to be prepared before the seasonal allergies kick in. In addition, these pre-preparations may help you and your child avoid severe allergies altogether. Consult your pediatrician beforehand and buy the medications as per their advice.
