I accidentally took 1 NyQuil this morning before work Is

Patient : I accidentally took 1 NyQuil this morning before work. Is it safe to take 1 DayQuil now? It has been about 2 hrs.
Doctor :   Hello. Welcome to ask the doctor. I have read your query. I understand your concern. Dayquil ans Nyquil are OTC an ti-Allergics used for common cold but since you have taken Nyquil 2 hours back so it's better to give a gap of at least 6-8hours before you take the next dose. Ideally the gap should be of 12 hours between the two doses. But in case of severe nasal congestion, it can be taken 8 hourly. The reason for this is that high doses of anti-Allergics can cause excessive sedation, drowsiness which might hamper your work and pose a threat to safe driving. I would advise you to take steam inhalations. Drink hot fluid for symptomatic relief. In case your symptoms persist after 6hours, you may take a dose of Dayquil. I hope it helps. If you have any further query, you may ask me. Stay healthy.
