Comprehensive Guide to Common Allergy Medications

As allergy seasons approach, symptoms like runny nose, itchy eyes, and sneezing can disrupt daily life. While avoiding allergens is ideal, medications are often necessary for relief. The market offers various options including tablets, liquids, nasal sprays, inhalers, skin creams, and injections. Some are available OTC, while others require a doctor's prescription. Understanding the different types of allergy medicines can help you choose the right treatment when needed.

Typically, allergy medications are categorized into several groups, each serving specific symptoms and conditions.

Different Types of Allergy Relief Medications

Antihistamines
These drugs target histamine release caused by allergic reactions, offering relief from symptoms like sneezing, runny nose, and watery eyes. They come in various forms such as pills, liquids, nasal sprays, and eye drops. OTC options include second-generation antihistamines like cetirizine, loratadine, and fexofenadine, known for fewer sedative effects compared to older options like diphenhydramine.

  • Oral medications
    Suitable for watery eyes, nasal congestion, or swelling, OTC antihistamines are widely used. Care should be taken to avoid overdose, which may cause drowsiness. Newer drugs tend to have less sedation.

Nasal sprays
Ideal for congestion and sneezing, nasal sprays such as azelastine and olopatadine provide quick relief. Overuse can lead to side effects like bitter tastes, drowsiness, or nasal irritation. Usage should be limited to a few days to prevent rebound congestion.

  • Eye drops
    OTC antihistamine eye drops like ketotifen and olopatadine help soothe red, itchy, or watery eyes. Keep refrigerated for stinging relief and avoid overuse.

Decongestants
These medications provide rapid relief from nasal and sinus blockage but are not suitable for everyone. Pregnant women, children, the elderly, or individuals with high blood pressure, heart issues, or glaucoma should avoid their use. Available in tablets, liquids, and nasal sprays, they include pseudoephedrine and combinations with antihistamines.

  • Oral and liquid decongestants
    OTC options like pseudoephedrine help alleviate sinus pressure. Combining decongestants with antihistamines is also common.

Corticosteroids
These medications reduce inflammation caused by allergies and are available as nasal sprays, inhalers, pills, eye drops, and skin creams. They are effective but may have side effects with long-term use.

  • Nasal sprays
    Popular options like fluticasone and mometasone help with nasal symptoms but should be used sparingly to avoid irritation.
  • Inhalers
    For asthma triggered by allergens, inhalers containing corticosteroids like beclomethasone or fluticasone are prescribed for daily use.
  • Topical and eye applications
    Corticosteroid eye drops and skin creams are used for severe symptoms but require doctor's guidance to avoid side effects like skin thinning or hormonal imbalance.

Leukotriene receptor antagonists
Oral medications that block leukotrienes help reduce allergy symptoms, especially in asthma and hay fever cases, and require a doctor’s prescription.

Immunotherapy
For persistent allergies, allergy shots or sublingual tablets for pollen, dust mites, or molds can offer long-term relief after several years of treatment.

Mast Cell Stabilizers
These help prevent allergic responses by stabilizing mast cells and are used when antihistamines aren’t effective. Available as sprays and eye drops, they are part of advanced treatment options.

Always consult healthcare professionals before starting any allergy medication, especially if you have other health conditions or take other drugs.
