Managing Nosebleeds in Patients Taking Qelbree (Viloxazine)
Nosebleeds in patients taking Qelbree should be managed using standard epistaxis protocols, as there is no specific evidence linking viloxazine to increased bleeding risk or requiring medication discontinuation.
Immediate Management of Active Nosebleed
The FDA label for Qelbree does not list epistaxis as a known adverse effect 1. Therefore, standard epistaxis management applies per the 2020 American Academy of Otolaryngology guidelines 2:
First-Line Home Treatment
- Lean forward and pinch the soft part of the nose for at least 5 minutes
- If bleeding slows, continue holding for a full 15 minutes
- Clear clots by gently blowing the nose, then spray 2 sprays of oxymetazoline or phenylephrine decongestant in the bleeding nostril
- Continue holding the soft part of the nose for 5 minutes after spraying (may repeat once)
When to Seek Emergency Care
Patients should go to the emergency department or call 911 if 2:
- Bleeding does not stop despite the above measures
- Bleeding is severe or persistent
- Patient feels weak or lightheaded
Medication Management Considerations
Do not discontinue Qelbree for nosebleeds. Unlike blood thinners, viloxazine is not associated with coagulation abnormalities 1. The guidelines specifically address blood-thinning medications, stating patients should "promptly check with the clinician who has prescribed the blood-thinning medication" and avoid additional doses only if bleeding is severe 2. This does not apply to Qelbree, which has no anticoagulant properties.
Preventive Measures
Educate patients on prevention strategies 2:
- Eliminate contributing factors: Stop nose picking and vigorous nose blowing
- Nasal hygiene: Use nasal saline gel or spray 1-3 times daily to moisturize nasal tissues
- Environmental modification: Use a bedside humidifier, especially in dry climates
Post-Treatment Care
If cautery or packing is required 2:
- Avoid nose blowing, strenuous activity, and heavy lifting for at least one week
- Do not place cotton or tissues in the nose
- Continue nasal saline gel or spray 1-3 times daily for lubrication
- Follow up within 30 days to document outcome
Clinical Pitfalls to Avoid
- Do not assume Qelbree caused the nosebleed without evidence of other contributing factors (dry air, trauma, hypertension, etc.)
- Do not stop Qelbree as this may destabilize ADHD treatment without addressing the actual cause of epistaxis
- Do not overlook systemic causes: Evaluate for hypertension, coagulopathy, or other medications that truly affect bleeding (aspirin, NSAIDs, actual anticoagulants)
The most common adverse effects of Qelbree are insomnia, headache, somnolence, decreased appetite, and fatigue 3, 4, 5—not bleeding complications. Standard epistaxis management without medication adjustment is appropriate.
