Facial Flushing Associated with Anxiety and Improved by Venlafaxine: A Case Report.

Facial flushing affects the work and life of patients. The specific pathogenesis and conditions of facial flushing may be complicated. A 47-year-old perimenopausal woman was presented to the Pain Management with a 4-month history of facial flushing. The patient didn't have any history of special illness or history of allergies. Treatments with methylprednisolone, thalidomide, hydroxychloroquine drugs or sympathetic blockages (stellate ganglion block) were unable to effectively improve the symptoms. We believed that the facial flushing might be associated with the anxiety. After two weeks of venlafaxine medication, the symptoms were 90% relieved. We found that venlafaxine effectively improved flushing that may be related to anxiety.

Introduction

Facial flushing affects the work and life of patients, and its specific pathogenesis and conditions may be complicated.1 Here we introduce the diagnosis and treatment process of a case of bilateral flushing.

Case Presentation

A 47-year-old perimenopausal woman was presented to the Pain Management with a 4-month history of facial flushing. She was obviously anxious. The facial flushing in her face occurred in both sides with postural changes, thermal stimulation and mood changes. One month ago, the symptoms of this patient were aggravated. Symptoms including skin burning sensation and sleep difficulty appeared. The patient was unable to sleep flat and slept only 2–3 hours per day (Figure 1A). In addition, the patient didn’t have any history of special illness or history of allergies. A variety of tests were done with her body, including autoimmunity antibody test, skull MRI test, however, nothing abnormal was found. What’s more, treatments with drugs (methylprednisolone, thalidomide, hydroxychloroquine, glycyrrhizic anhydride tablets, ketotifen) or 10 times sympathetic blockages (stellate ganglion block) were unable to effectively improve the symptoms (Figure 1B). We invited dermatology, rehabilitation, hematology and other departments for consultation and multidisciplinary cooperation, and invited experts from higher-level hospitals for consultation, but no definite cause was found. We discussed the condition with the psychologist again, and finally we believed that the facial flushing might be associated with the anxiety. Venlafaxine inhibits the reuptake of serotonin and norepinephrine. We discussed the use of venlafaxine with the hospital pharmacy department and informed the patient. Then, venlafaxine was used. Miraculously, the facial flushing was markable improved in the following days. After two weeks of medication, the symptoms were 90% relieved. The patient was satisfied with the treatment, and the mood state improved significantly. Finally, the facial flushing of the patient was disappeared after taking venlafaxine for three months (Figure 1C).

Discussion

Perimenopausal women are prone to anxiety, and there may be abnormalities in sympathetic nerve function and vasomotor function.2,3 In addition, Jenifer et al found that venlafaxine may improve female hot flashes by regulating skin capillary perfusion.4 In fact, venlafaxine is a commonly used norepinephrine reuptake inhibitor and serotonin modulator, which can effectively improve anxiety and depression.5

Rosacea is a chronic, inflammatory skin disease that affects cheeks, nose, chin, and forehead. Rosacea is characterized by episodes of exacerbation and remission. The diagnosis of rosacea is based on clinical features and careful history taking. The differential diagnosis includes seborrheic dermatitis, flushing disorders, lupus erythematosus, etc.6 A recent systematic reviews showed that rosacea may predispose patients to develop depression and anxiety.7 In this case, the patient’s facial redness has consulted to the dermatology department, and we invited dermatology, rehabilitation, hematology and other departments for consultation and multidisciplinary cooperation. Considering the patient’s extreme anxiety and the good treatment effect of venlafaxine, as well as the follow-up situation, we believed that facial flushing caused by anxiety, but do not rule out rosacea. In addition, beta-blockers propranolol, carvedilol and clonidine were recommended first-line treatment in rosacea flushing.6,8 Venlafaxine inhibits the reuptake of serotonin and norepinephrine. Following treatment with venlafaxine, there was a reduction in flushing and endothelial dependent perfusion response in postmenopausal women.4 We agree that rosacea may also benefit from venlafaxine. This is very interesting and deserves further study.

In this case report, we found that venlafaxine may improve bilateral flushing by improving patient anxiety. However, its specific mechanism remains to be explored.

Conclusion

In conclusion, we found that venlafaxine effectively improved facial flushing that may be related to anxiety.
