Chronic rhinosinusitis (CRS) with nasal polyps: US-approved treatments and how families in the Gulf can access them

Reviewed by the Reserve Meds clinical operations team on 17 October 2026.

What is chronic rhinosinusitis with nasal polyps?

Sinusitis means the sinuses, the hollow air spaces in the bones around the nose, are inflamed. Chronic sinusitis lasts more than 12 weeks and can continue for months or even years. Allergies, nasal problems and certain diseases can cause it.^[1]

Symptoms can include congestion, mucus draining down the back of the throat, cough and fatigue. Some people with chronic rhinosinusitis also have nasal polyps, a form the US labels call chronic rhinosinusitis with nasal polyps (CRSwNP).^{[1, 2]}

For adults whose disease stays inadequately controlled, several biologic medicines are approved in the US as add-on maintenance treatment for chronic rhinosinusitis with nasal polyps (CRSwNP).^{[2, 3, 4, 5]}

Chronic rhinosinusitis with nasal polyps in the Gulf

Gulf ear, nose and throat specialists have published on chronic rhinosinusitis, including a phenotype-based study of severe asthma in Kuwait and a retrospective analysis of chronic rhinosinusitis symptoms after COVID-19.^{[6, 7]}

We checked every medicine on this page against the full SFDA drugs list and the Abu Dhabi Department of Health drug code list on 17 October 2026. 4 of 4 were listed in Saudi Arabia and 4 of 4 in Abu Dhabi. The result for each medicine is shown below. A listing does not mean every hospital stocks the medicine, and federal UAE, Kuwait, Qatar, Bahrain and Oman registers were not checked.^{[8, 9]}

How families in the Gulf can access treatment

If the medicine is listed in your country. Ask your specialist and the hospital about local supply first. A listing does not mean every hospital stocks the medicine, but it is usually the fastest route, and you may not need us.

If it is not registered. The usual legal route is a named-patient request: the treating hospital, on your specialist's written request, asks the national regulator for permission to import the medicine for one patient, using the US FDA approval as the reference. In Saudi Arabia the SFDA Special Access Program guidance covers these requests; in Bahrain, NHRA Circular 41 of 2020 sets the procedure. Other Gulf countries have their own procedures, which the hospital confirms.^{[10, 11]} Once approval is in place, Reserve Meds arranges supply through a US-licensed pharmaceutical wholesale partner to the hospital.

Who does what

• Your treating specialist decides whether a medicine is right for the patient and writes the medical letter.
• The hospital checks local supply, files any import request, and gives the treatment safely.
• The national regulator decides whether to approve the import of a medicine that is not registered.
• The manufacturer decides where its medicine can be supplied, especially for cell and gene therapies.
• Reserve Meds helps organize records, coordinates US supply through our wholesale partner, shipping and updates to your family. We do not give medical advice.

Documents you will usually need

• A letter from the treating specialist with the diagnosis, past treatments and why this medicine is being considered
• Reports that confirm the diagnosis, such as genetic, pathology, imaging or laboratory results, translated into English where needed
• Recent clinic notes and a list of current medicines
• For a hospital import request: the prescription, the hospital's request form and the written consent of the patient or guardian
• Proof of the US FDA approval and the US prescribing information (we can supply these)

We give you a written timeline estimate for your case before you commit. The regulator, the hospital or treatment center and the manufacturer set their own timelines.

What treatment costs

Quote on request. Your total cost depends on the medicine, the dose, shipping, import steps and coordination. Your coordination fee is quoted in writing for your case before you commit. No hidden charges.

How Reserve Meds helps

Reserve Meds is a digital health company. Medicines are supplied through a US-licensed pharmaceutical wholesale partner. We help your doctor and hospital prepare the file, arrange US supply and temperature-controlled shipping once approval is in place, and keep your family updated. We coordinate access to FDA-approved medicines only. Investigational medicines are only available through a manufacturer's expanded-access program requested by the treating physician; we can explain that route, but we do not supply them.
