Hi Sir, Hope you are doing good. My sister took a dosage of 9 tablets of stalopalm and was noticed sleeping unusual. Later, after discovering this after 5 hours after the intake, we had her stomach washed and we saw her going drowsy. After 3 days she started complaining of drowsiness, heavy head, vertigo and breathlessness. All the ABG,Biochemical and LFT results came normal. Vitals are also stable. I am not certain about CO2 levels. May I know what can be the reason for this and how this can be recovered from? Regards
