I have a cold and I've been taking Mucinex-D. Around 1pm today, I took 2 pills and haven't had a dose since. The 2 pills at once works wonders, but I don't want to overdo it. I was wondering if I could take a benadryl tonight and then begin again with the 2 mucinex-ds in the morning. Good idea? Bad idea?
Before I give you an answer, make sure the Mucinex D is actually Mucinex D...sorry if that is confusing, but there is also a Mucinex DM, which is different in chemical compound from Mucinex D.
Mucinex D (guaifenesin and pseudoephedrine) can safely be used with plain old benadryl (diphenhydramine), however you should NOT take EITHER product for more than 7 days. If your symptoms persist for longer than 7 days, see your doctor.
You should not take any other products containing any of the active ingredients in benadryl or mucinex d during the time you are using them.
A nasal spray may also help with nasal congestion. As long as it is straight saline, it may be used in conjunction with benadryl and mucinex d.
