Patient's Query
Hello doctor,
My friend took a higher-than-usual dose of a sleep aid specifically around 350 mg of Unisom (Doxylamine succinate). This was not a suicide attempt, but he is extremely drowsy, and I am concerned. He does have a history of depression and substance use. I am wondering if this dose could be dangerous or potentially harmful.
Please help.
Thank you.
Hello,
Welcome to icliniq.com.
I completely understand your concerns.
The usual dose of Doxylamine succinate as an antihistamine will not exceed greater than 60 mg per day. Excessive dose may cause CNS (central nervous system) depression, palpitations, tachycardia, disorientation, dizziness, drowsiness, headache, paradoxical central nervous system stimulation, vertigo, anorexia, constipation, diarrhea, dry mucous membranes, epigastric pain, xerostomia, dysuria, urinary retention, blurred vision and diplopia.
So, there is no specific antidote treatment and symptomatic support may be required. If it is severe CNS depression, it can lead to coma. So, please consult your doctor immediately. He will examine and treat him accordingly. For more information consult an internal medicine physician online.
I hope this helps.
Kindly revert if there is any query.
Thank you.
Same symptoms don't mean you have the same problem. Consult a doctor now!
