Would prometh-cod cough syrup cause hiccups?

Yes, promethazine-codeine cough syrup can potentially cause hiccups as a side effect. The active ingredients, especially codeine, may affect the central nervous system and could lead to involuntary contractions of the diaphragm, resulting in hiccups. However, individual reactions can vary, and not everyone will experience this side effect. If hiccups persist or are bothersome, it’s advisable to consult a healthcare professional.
