Dear sir,

Many times I was suffered from normal cough and cold. I was consulted well known ENT specialist doctor in Manglore, India. He prescribed me of Allercet DC, Hicet DC & Ebast DC on different visits. I was not aware of this website or other which provides useful info on drugs side effects. I was experienced few of normal side effects by these drugs which you specified over here in this website.

And I was also wondered by getting known about there so called drugs which are generally prescribed by doctors to treat normal cough and cold have the chemical ingredients which can also show Heart related side effects. And which is a shocking news to everyone who using them.

Great work by you peoples who are involved with this website and providing vital information on every drug and its ingredients, side effects etc.

My question is to those doctors who prescribe these kind of drugs to treat normal diseases: "why they dont refer online informations about side effects of several drugs they prescribe?

Why those drug making companies use such serious side effects causing ingredients in their products? And they dont rely upon safe ingredients?

Finally why goverment let these drugs into the market?
