Azelastine hydrochloride nasal spray is a second-generation antihistamine indicated for the symptomatic relief of seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis in adults and children aged 6 years and older. It works as a potent, selective H1-receptor antagonist and also inhibits the release of inflammatory mediators, including leukotrienes and platelet-activating factor, from mast cells and other cells involved in the allergic response. Azelastine provides rapid relief from nasal symptoms such as rhinorrhoea, sneezing, nasal pruritus, and congestion without causing significant sedation.
Usual adult dose: For adults and children aged 12 years and older: one actuation (0.14 ml containing 0.14 mg azelastine hydrochloride) into each nostril twice daily. This corresponds to a total daily dose of 0.56 mg. Once symptoms are controlled, some patients may be maintained on one actuation per nostril once daily. For children aged 6 to 11 years: one actuation into each nostril twice daily. The bottle should be primed before first use by pumping until a fine mist appears. The head should be tilted forward during administration, and the nozzle should be cleaned after each use.
Dosage form: Nasal spray, solution in a 10 ml amber glass bottle fitted with a metered-dose pump and nasal applicator. Each bottle contains 10 ml of a 0.1% w/v solution (1 mg/ml), delivering approximately 70 metered actuations. Each actuation delivers 0.14 mg azelastine hydrochloride in 0.14 ml solution.
Onset of action: Symptomatic relief of allergic rhinitis symptoms begins within 15 to 30 minutes of intranasal administration. Maximum antihistaminic effect at the nasal mucosa occurs within 2 to 3 hours, and improvement in nasal congestion is typically evident after several days of regular twice-daily use.
Duration of action: A single intranasal dose provides symptomatic relief lasting up to 12 hours, supporting a twice-daily dosing regimen. The plasma elimination half-life of azelastine is approximately 20 hours, while its active metabolite, desmethylazelastine, has a half-life of approximately 45 hours.
Alcohol recommendation: Alcohol consumption should be avoided or strictly limited during treatment with azelastine nasal spray. Although systemic absorption is low following intranasal administration, alcohol may enhance the potential for central nervous system depression and exacerbate any sedative effects. Patients should exercise caution when driving or operating machinery, particularly if alcohol is consumed.
Most common side effects: Bitter taste dysgeusia is the most frequently reported adverse effect, occurring in approximately 20% of patients. This can be minimised by tilting the head forward during administration to reduce post-nasal drip. Other common side effects include nasal irritation, sneezing, epistaxis, and mild transient somnolence. Headache and application site reactions such as burning or stinging sensations may also occur.

Azelastine is an antihistamine nasal spray used mainly for hay fever and year-round allergic rhinitis. Unlike oral antihistamines that take a tablet to reach your nose via the bloodstream, this one goes directly onto the nasal lining where the allergic reaction is actually happening. That local delivery matters. It starts blocking histamine receptors within 15 to 30 minutes of spraying. For someone walking into a high-pollen day, that speed makes a tangible difference.
The standard dose for adults and children over 12 is one spray in each nostril twice daily. Some people get adequate control with once-daily use once the worst of the season passes. The 10 mL bottle delivers approximately 100 metered sprays, each containing 0.14 mg of azelastine hydrochloride. A bottle typically lasts about a month at the standard twice-daily dosing. For children aged 6 to 11, the same dose applies, but treatment should be supervised by a doctor.
Azelastine is a second-generation H1 receptor antagonist, but calling it just an antihistamine undersells it. It also stabilises mast cells and reduces the release of leukotrienes, prostaglandins, and other inflammatory mediators that keep the allergic cascade rolling. Histamine is only the first wave. The late-phase allergic response, the congestion, the nasal obstruction, the sinus pressure that sets in hours after exposure, that is driven by these other mediators. Azelastine dampens both phases.
The drug has high receptor affinity and dissociates slowly from the H1 receptor, which partly explains why twice-daily dosing is enough. Systemic absorption is low, around 40% of the intranasal dose reaches the bloodstream, and plasma concentrations after a single nasal dose are in the picogram-per-millilitre range. It is metabolised by CYP450 enzymes in the liver, primarily CYP3A4, and the active metabolite desmethylazelastine contributes to the overall antihistamine effect. The elimination half-life of azelastine is about 20 hours, and the metabolite hangs around for roughly 45 hours.
Prime the pump before first use, usually 2 to 4 sprays into the air until a fine mist appears. If you have not used it for a week or more, re-prime with a spray or two. Skip this step and you will get a weak stream, not a mist, and the dose will not reach the nasal mucosa properly.
Blow your nose gently first. Tilt your head forward slightly, not back. Insert the nozzle into one nostril, close the other with a finger, and spray while inhaling gently through your nose. Do not sniff hard. Sniffing forcefully pulls the medication straight down the throat instead of keeping it in the nasal cavity. Repeat on the other side. If some drips back out or the taste hits the back of your throat, it is not wasted, enough stays where it needs to be. Rinse the nozzle after use and wipe it dry before capping.
If you forget a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed one. Do not spray twice as much to compensate.
The most common complaint is a bitter taste. It affects roughly 1 in 5 users and happens because a small amount of the spray drains from the nasal cavity into the throat. Drinking water or eating something after use helps mask it. The taste does not mean the spray is not working. It is just an annoying quirk of the formulation.
Nasal irritation, stinging, itching, sneezing, or a dry feeling inside the nose, occurs in about 1 in 10 people, particularly in the first few days. This usually settles as the mucosa adapts. Using a saline nasal spray about 15 minutes before azelastine can help if the dryness is persistent. Drowsiness is less common than with oral antihistamines but not impossible. Around 2% to 5% of users report feeling sleepy. If you are affected, taking the evening dose right before bed works in your favour.
Epistaxis, nosebleeds, can occur with prolonged use, especially if the spray nozzle is angled incorrectly and hits the septum repeatedly. Aim slightly away from the midline, toward the outer wall of the nostril. If nosebleeds persist, stop using it and let your GP or pharmacist know.
Pregnancy is not a contraindication, but the data are limited. Animal studies at oral doses far exceeding the intranasal equivalent showed no teratogenicity. The amount absorbed systemically from the spray is tiny. That said, the standard advice in the UK is to avoid it in the first trimester unless clearly necessary and to use it only after discussing it with your midwife or consultant.
Breastfeeding is similar. Azelastine passes into breast milk in amounts that are probably too small to affect a nursing infant, but the manufacturer advises caution. A non-sedating oral antihistamine like loratadine is often suggested as an alternative during breastfeeding, though nasal azelastine is unlikely to cause harm given the minuscule systemic exposure.
Older adults can use the standard dose without adjustment. The drug is not anticholinergic and does not carry the cognitive risks of first-generation antihistamines. That is relevant because many older hay fever sufferers default to cheap sedating antihistamines out of habit, which is genuinely risky. Azelastine is a safer choice.
People with significant renal or hepatic impairment have not been studied extensively with intranasal azelastine. Given that systemic levels are already negligible, clinically meaningful accumulation is improbable. Standard dosing is considered safe, but a cautious approach, once-daily to start, is reasonable if there is severe liver disease.
Most people can drive without issue. The bitter taste and mild nasal discomfort are nuisances, not impairments. If you are among the small percentage who experience drowsiness, treat it like any other sedating medication and avoid driving until you know how it affects you. The drowsiness tends to be mild and transient.
Alcohol does not interact directly with intranasal azelastine in a pharmacological sense. However, alcohol causes nasal vasodilation and can worsen congestion on its own. If you have been drinking heavily the night before and wake up congested, the spray still works, but you are giving it a bigger problem to solve. Moderate drinking is not an issue.
Serious drug interactions with intranasal azelastine are rare. The systemic dose is so low that CYP450-mediated interactions, theoretically possible with strong CYP3A4 inhibitors like ritonavir or ketoconazole, do not translate into clinically meaningful effects. The plasma concentrations barely register even without an inhibitor present.
The one interaction worth paying attention to is with other CNS depressants. If you are already taking sedating antihistamines, benzodiazepines, opioids, or gabapentinoids, the small additive sedation from azelastine might tip the balance. It is not a dangerous interaction, but feeling groggier than expected in the morning is enough to warrant spacing things out. Taking azelastine at night and the other sedating medication at a different time usually solves it.
Using azelastine alongside intranasal corticosteroids, fluticasone, mometasone, beclometasone, is not only safe but often more effective than either alone. Combination products like Dymista pair azelastine with fluticasone propionate in a single spray for moderate to severe allergic rhinitis. The two mechanisms are complementary, not competing.
Oral antihistamines, cetirizine, loratadine, fexofenadine, are the obvious first alternative. They are cheap, widely available without prescription, and effective for many people. Their weakness is nasal congestion. Histamine is not the only driver of a blocked nose, and oral antihistamines leave leukotrienes and prostaglandins largely untouched. Azelastine covers a broader spectrum of mediators locally.
Intranasal corticosteroids are the gold standard for moderate to severe allergic rhinitis. They reduce inflammation across the board but take days to reach full effect. Azelastine works faster. The two used together outperform either alone, which is why Dymista exists.
Sodium cromoglycate nasal spray is a mast cell stabiliser available over the counter. It prevents mast cells from degranulating in the first place. It needs to be used four times daily and works best started before allergen exposure. Compliance is poor because of the frequency, but for mild, predictable hay fever it has a place.
Montelukast, a leukotriene receptor antagonist taken as a tablet, is licensed for allergic rhinitis in patients who also have asthma. It is not first-line for rhinitis alone, but for someone with both conditions, it addresses the lower and upper airways simultaneously.
Immunotherapy, grass pollen or house dust mite desensitisation, is the only disease-modifying option. It involves years of treatment, either sublingual tablets daily or subcutaneous injections at a clinic. For someone who has tried every spray and tablet and still cannot function during pollen season, it is worth discussing with an allergist.

The nasal spray is designed for allergic rhinitis. The eye drops are for allergic conjunctivitis. They contain the same active ingredient at different strengths and are not interchangeable. If you have both nose and eye symptoms, using the spray for your nose and the drops for your eyes is entirely reasonable. Just do not put the nasal spray in your eyes.
Generic azelastine and branded Rhinolast are bioequivalent. The bottle design and pump mechanism differ slightly between manufacturers, and some people find one easier to use than another. The mist quality can vary. If you have tried one brand and found it dripped down your throat excessively, switching to a different generic is worth trying before you abandon the drug altogether.
The combination product Dymista is a different proposition. It contains azelastine and fluticasone in a single device and is intended for patients whose symptoms do not respond adequately to either component alone. It is more expensive and remains prescription-only. For moderate persistent rhinitis that breaks through monotherapy, it often works when simpler approaches have failed.
How quickly does azelastine nasal spray work?
Onset is about 15 to 30 minutes for histamine-driven symptoms, sneezing, itching, runny nose. The effect on congestion takes longer because that involves the late-phase inflammatory response. Full benefit is usually seen within a few days of regular twice-daily use.
Can I use azelastine with other nasal sprays?
Yes, with a caveat on timing. Leave at least 10 to 15 minutes between different nasal sprays. If you use a saline rinse or a steroid spray, do that first, then azelastine. If you reverse the order, the azelastine gets washed away before it has time to bind to receptors.
Is the bitter taste normal?
Very normal. It is the most common side effect and affects roughly 20% of users. It is not a sign of incorrect technique, though sniffing less forcefully after spraying can reduce it. Drinking water or eating a small amount of food afterwards masks it effectively.
Can I use azelastine long term?
Yes. It is safe for continuous use throughout pollen season and for perennial allergic rhinitis year-round. There is no tachyphylaxis, it does not lose effectiveness over time, and no evidence of nasal mucosa damage with prolonged use. The main risk with long-term use is epistaxis if the spray repeatedly hits the septum.
Does azelastine help with non-allergic rhinitis?
It can. Non-allergic rhinitis is a broad category, and azelastine is not licensed for it, but some patients with vasomotor rhinitis triggered by temperature changes, strong smells, or smoke report improvement. The mast-cell-stabilising effect probably accounts for this. It is not as reliably effective as it is for allergic triggers, but it is a low-risk thing to try when other options have been exhausted.
