Dio Plus Tablet Information
Dio Plus is a topical antiseptic containing 10% Povidone-Iodine (equivalent to 1% titratable iodine) intended for external use only on wounds and skin infections—it is NOT indicated for nasal congestion or allergic rhinitis. 1
Critical Clarification
There appears to be confusion about this product. Based on FDA labeling, Dio Plus is a topical wound antiseptic, not a nasal or allergy medication. The evidence provided shows it contains Povidone-Iodine for treating minor cuts, scrapes, and burns—completely unrelated to rhinitis management.

If You're Looking for Nasal Congestion/Allergic Rhinitis Treatment
If the question intended to ask about combination antihistamine-decongestant products for rhinitis, the evidence-based approach is:
For moderate-to-severe allergic rhinitis with nasal congestion, intranasal corticosteroids (INCS) are the most effective monotherapy. 2 When congestion remains problematic despite INCS, the combination of intranasal antihistamine + intranasal corticosteroid (e.g., azelastine + fluticasone) is more effective than either agent alone. 3, 4
Oral decongestants (pseudoephedrine or phenylephrine) combined with antihistamines can relieve nasal congestion but cause side effects including insomnia, irritability, palpitations, and potential blood pressure elevation. 2 Notably, phenylephrine's efficacy as an oral decongestant has not been well established 2, with recent evidence showing no significant benefit over placebo 5.
Use oral decongestants with extreme caution in patients with:
- Cardiovascular or cerebrovascular disease
- Hypertension (monitor blood pressure)
- Hyperthyroidism
- Closed-angle glaucoma
- Bladder neck obstruction 2
In children under 6 years, oral decongestants carry serious risks including agitated psychosis, ataxia, hallucinations, and death—risks must be carefully weighed against benefits. 2
