I don't know if this is from the medicine or not.

I have been on concerta for about 6 months now 3 of them 54mg.

Im not sure but i think i had a cold 3 weeks ago. I say I am not sure because I only had a sore throat and felt a bit tired for about 2-3 days. But after these days I have had constant phlegm and coughing. I have not been able to cough it out and it is very annoying.

Is this a known side effect that anyone else has experienced? Should I contact my doctor about it or wait a bit longer?

I have searched a bit on the internet and some say that they never got rid of it without pausing the intake of meds while others say it went away.
