Suffering With Sinus, Feel Jumpy And Light Headed With Mucinex. Advised Mucinex Or Robitussin. Suggestion?

Just came from walk in where I was told I had a bad sinus infection . Will be taking an antibiotic but my question is when I take Mucinex it makes me very jumpy and light headed. I thought the dr said it was from the guaifenesin and to take mucinex or robitussin exportorant. It looks as though all the mucinex products contain guaifenesin. Did I misunderstand?

Hello,

Guaifenesin is the Pharmacological name of the drug(Medical name).

But the brand name of Guaifenesin will differ depending on the companies.

Mucinex and Robitussin are different brands names for the same drug Guaifenesin.

So you need to take either mucinex or Robitussin and not the both.

you understand good
but sinus infections are all allergies and after neglecting milld allergies off and on you get infected sinuss
and you need to take antiallergic instead of bronchodilators
if infected can take doxycycline 100 mg bd for 7 days off and on as hey are fast clearing of infections
take anti allergic bd dose
add antacid and syp cpm and codeine combination one tsf nighttake flunarazine 5 mg night continue 3 wk
but get xray pns waers view and take ent doctorconsultation to cure it completely
