Brief Answer:

Detailed Answer:
hello and thank you for sending the question.

Most likely there will be no significant negative side effects from taking a double dose of this particular medication.

I would recommend that you stay well hydrated, drinking plenty of fluids for the next 24 hours.

You might experience some fatigue or mild sedation. otherwise I would not anticipate any serious side effects for you.

within 24 hours the full affect of taking this medication should be out of your system. If you need to resume taking this for cough suppressant you can do so in 24 hours.

If you experience any strange symptoms such as nausea, vomiting, blurred vision, palpitations or shortness of breath please contact your primary care doctor or go to your local emergency room for evaluation.

thank you again for sending the question.
