Looking for a Primatene Mist coupon? Primatene Mist (Primatene MIST HFA) is an inhaled epinephrine aerosol and the only FDA-approved over-the-counter asthma inhaler sold in the United States. It offers temporary relief of mild symptoms of intermittent asthma — wheezing, chest tightness, and shortness of breath — in adults and children 12 and older who have already been diagnosed with asthma by a doctor. Because it is sold over the counter, you do not need a prescription to buy it, and an Rx.com coupon can help you compare what you would pay at pharmacies near you. Enter your ZIP above to see today's price.
What Primatene Mist is and how it works
Primatene Mist HFA contains epinephrine, a fast-acting bronchodilator that belongs to a group of medicines called sympathomimetics (alpha- and beta-adrenergic agonists). When inhaled, it relaxes the muscles around the airways so they open up, which can quickly ease mild wheezing, chest tightness, and shortness of breath. It is meant only for the temporary relief of mild, intermittent asthma symptoms in people 12 and older who have already been diagnosed with asthma by a doctor.
Primatene Mist is not a controller or maintenance medicine. It does not treat the underlying inflammation of asthma and is not intended for severe or persistent asthma. Medical guidelines discourage using it in place of a doctor-prescribed asthma controller. Talk with your provider about a long-term asthma plan; this product is not a substitute for that care.
How to use it, and how to save with an Rx.com coupon
Follow the Drug Facts label and your doctor's guidance. Shake the inhaler well, prime it before first use as directed, and take one inhalation at the first sign of symptoms. If you are not relieved in about one minute, the label allows one more inhalation. Do not use more than 2 inhalations at once and do not use more than 8 inhalations in 24 hours. Rinse the mouthpiece and let it dry as directed to keep it working properly.
Because Primatene Mist is sold over the counter, prices can vary a lot from one pharmacy to the next. Some over-the-counter products cost less when you use a pharmacy discount coupon or when a prescriber writes them as a prescription. An Rx.com coupon is free to use and lets you compare the cash price at pharmacies near you — enter your ZIP above to see today's price. There is no manufacturer copay card for this product; you can find official product information on the manufacturer's own website at Primatene.com, and any promotional terms there may vary.
Primatene Mist vs. prescription inhalers
Primatene Mist uses epinephrine and is the only asthma inhaler you can buy without a prescription. Most doctors, however, prescribe short-acting inhalers that use albuterol, a different bronchodilator that is more selective for the airways and generally causes fewer whole-body effects such as a racing heart or jitteriness. If you find yourself reaching for Primatene Mist often, that is a sign your asthma may not be well controlled and you should see a provider.
Prescription rescue-inhaler options your doctor may discuss include albuterol and brand versions such as Ventolin HFA and ProAir HFA. Injectable epinephrine is a different product used for severe allergic reactions, not for routine asthma symptom relief. These prescription products require a prescription, but an Rx.com coupon can help you compare their prices too.
Safety and when to get help
Primatene Mist is only for people who have been diagnosed with asthma by a doctor — do not use it if you have never been diagnosed with asthma. Because epinephrine can affect the heart and nervous system, it may cause a rapid or irregular heartbeat, higher blood pressure, tremor, nervousness, or trouble sleeping. Stop use and contact a doctor if these happen. Avoid caffeine while using it, and ask a doctor before use if you have heart disease, high blood pressure, diabetes, thyroid disease, glaucoma, a seizure disorder, or trouble urinating due to an enlarged prostate, or if you take MAO inhibitors, tricyclic antidepressants, or other stimulant or decongestant medicines.
Get emergency care if your symptoms are not relieved within 20 minutes, if they get worse, if you need more than 8 inhalations in 24 hours, or if you have more than 2 asthma attacks in a week — these can be signs of a serious problem. This information is not medical advice; talk with your own provider about whether Primatene Mist is right for you and about a proper asthma treatment plan.
