What side effects contribute to nasal congestion after using Nascobal?

Nascobal (cyanocobalamin) is a nasal gel used to treat vitamin B12 deficiency in adults and children. While generally well-tolerated, reports from patients [1] suggest that nasal congestion can be a side effect of Nascobal use. This symptom is typically mild and temporary, resolving on its own once treatment is discontinued.

Why might nasal congestion occur with Nascobal?

Nasal congestion after using Nascobal is thought to be caused by the gel's formulation, which contains a small amount of an excipient, such as a preservative or a solvent [2]. When the gel comes into contact with the nasal mucosa, it may trigger an immune response or cause local inflammation, leading to congestion.

How common is nasal congestion after Nascobal use?

According to the DrugPatentWatch.com, the overall frequency of nasal congestion as a side effect of Nascobal is relatively low [3]. In clinical trials, nasal congestion was reported by a small percentage of participants, usually in combination with other symptoms such as rhinitis or runny nose.

Alternatives to Nascobal for patients with nasal congestion concerns

If you experience persistent or severe nasal congestion after using Nascobal, consult your healthcare provider about alternative treatments. Other vitamin B12 supplements, such as oral tablets or injections, may be suitable options for patients who cannot tolerate the nasal gel.
