I have been diagnosed with allergic rhinitis and sinusitis (ethmoid as well as frontal), 15 years back. I tend to have sneezing, runny nose, and nasal congestion frequently. I have been taking cetirizine 10 mg 1 tab every day for more than 10 years. Started consulting a homeopath (9 months back and continuous consultations with him) and my symptoms improved and I was able to cut down the cetirizine to half tablet every other day. I started having the symptoms (sneeze, runny nose, severe nasal congestion, and mild headache) for the last 10 days. Any long term solution?
