I had sinus infection back in January and was on doxycycline. I currently take flecainide and aciphex. I have no appetite. HELP [/INST] Hello, Loss of sense of taste and smell is commonly seen when you have a sinus infection as a result of sinus and nasal congestion. Alter taste is commonly seen as a side effect of the medication. So my suggestion is to consult your physician and get evaluated and thorough clinical examination done and treated accordingly. For now, you should start cleaning your tongue using a tongue cleaner. Gargle with 1:1 solution of HY Chat Doctor.   </s>
