Suggest Remedy For Side Effects From Mucinex DM

i was taking mucinex dm and started having the following side effects: sore gums, headache,muscle and joint pains, dizziness, sweats, shortness of breath, developed a terrible small little simple rash on my face from the medication. I started taking the medication on Friday and I m still feeling the side effects. Help, I already put in a call to my doctor and I m waiting to hear back. A very worried and concern consumer. I feel this medication should be taken off the market. I have already left a message for the tea with a complaint regarding this drug.
