question: Hi doctor, i have been suffering from allergic rhinitis since 10 years. It all starts with sneezing which leads to itching on the upper mouth and in hours time it changes to throat pain. Throat irritation and pain produce greenish sputum and the irritation on the throat quickly changes to severe cough. Severe cough means its as severe as if im may faint after a cough session. During this time the sputum become greenish and breathhing difficulty starts. During this period i feel heavyness, conjestion and chocking in my chest. Some times fever also persist. nowadays it takes more than a months time to become normal. Anti biotics and cough syrups were used to treat. Reacently a doctor prescribed me Telekast F. But that never helped me from the cycle of events repeated. Now adays i am freequently getting infected. Is long term use of Telekast F help? Is telekast F is the proper prescription? Does there other effective medicin which can save me from this deadly allergic cough?
