• Drug Interactions with Propranolol?

I was reading on this site the drug Interactions with Propranolol and Guaifenesin, without the combination of Sudafed or any other nasal decongestant. I am a 22 year old male and was diagnosed with essential hypertension and currently take 20 mg Propranolol twice a day. I have a pretty bad cough and was wondering if it’s safe to take Guaifenesin if I haven’t taken Propranolol yet for the day and if it’ll increase my hypertension.

Guaifenesin has no effect on hypertension and has no interaction with Propranolol.
