Looking for a Dulera coupon? Dulera (mometasone furoate / formoterol fumarate) is a brand-name maintenance inhaler for asthma, and because there is no generic version yet, the price can be a real burden. Rx.com offers a free cash discount coupon you can use at the pharmacy counter, no insurance required. Enter your ZIP code above to see today's Dulera price at pharmacies near you and get your coupon.
What is Dulera and how does it work?
Dulera is a combination inhaler that pairs two medicines: mometasone furoate, an inhaled corticosteroid (ICS) that reduces swelling and inflammation in the airways, and formoterol, a long-acting beta2-agonist (LABA) that relaxes the muscles around the airways to keep them open. It is FDA-approved for the maintenance (long-term control) treatment of asthma in adults and children 5 years and older.
Dulera is a controller inhaler, not a rescue inhaler. It is meant to be used every day to prevent asthma symptoms, and it does not relieve a sudden asthma attack or bronchospasm already in progress. Doctors typically prescribe it when asthma is not well controlled on an inhaled corticosteroid alone, or when the severity of the asthma calls for both an ICS and a LABA. Dulera is not approved to treat COPD.
Dulera cost: manufacturer savings card vs. Rx.com cash coupon
There is no generic version of Dulera available, so this brand-name inhaler can be expensive without help. There are two main ways to lower the cost. The manufacturer (Organon) offers a Dulera savings card, which you can review at the official Dulera savings page. Manufacturer copay cards like this are generally limited to people with commercial (private) insurance and typically exclude those covered by Medicare, Medicaid, or other government plans. Terms and eligibility vary, so check the manufacturer's page for the current details.
If you are uninsured, on Medicare, or your savings card is declined, the Rx.com cash coupon is an alternative. It is a free discount coupon that works like a cash price at the pharmacy, no insurance needed. You can only use one discount at a time (you cannot combine a cash coupon with your insurance), so it helps to compare both. Enter your ZIP above to see today's Dulera price with the Rx.com coupon. Organon also runs patient support and assistance programs for eligible patients, which you can learn about at organon.com.
Dulera vs. Symbicort and other alternatives
Dulera belongs to the same class of ICS/LABA combination inhalers as several other brand and generic products. If you and your prescriber are weighing options or looking for a lower-cost alternative, these are commonly compared:
- Symbicort (budesonide / formoterol) and its generic, budesonide-formoterol
- Advair and Advair Diskus (fluticasone / salmeterol)
- Breo Ellipta (fluticasone furoate / vilanterol)
- Flovent (fluticasone), an inhaled corticosteroid used on its own
These inhalers use different corticosteroid and beta-agonist ingredients and come in different devices, so they are not identical. Any switch should be made by your prescriber. Because some of these have generic versions, comparing prices across them may reveal a lower-cost option; check each drug's page above for today's pricing.
Dulera safety: what to know
Dulera contains formoterol, a LABA. Older labeling for the LABA class carried a boxed warning about a possible increased risk of asthma-related death, but large safety studies of ICS/LABA combination inhalers (including this drug class) did not show a significant increase in serious asthma-related events compared with an inhaled corticosteroid alone, and current labeling reflects that. Dulera should only be used as maintenance therapy alongside its corticosteroid component, never as a stand-alone (monotherapy) asthma treatment, and never to treat sudden symptoms or an asthma attack, keep a separate rescue inhaler on hand for that. It is not intended for people whose asthma can be controlled with an inhaled corticosteroid alone.
Possible side effects and risks include oral thrush (candidiasis), a higher chance of pneumonia and other respiratory infections, effects on the immune system, reduced bone mineral density, possible slowed growth in children, glaucoma or cataracts, adrenal suppression, low potassium, high blood sugar, and heart-related effects such as a fast heartbeat. Dulera should not be used as the primary treatment of status asthmaticus or acute episodes, or by anyone allergic to its ingredients. This is general information, not medical advice, talk with your doctor or pharmacist about whether Dulera is right for you.
