Nausea and vomiting
Caffeine is a stimulant that enhances the effect of Paracetamol/Acetaminophen. It boosts alertness and reduces fatigue by stimulating the central nervous system.
Diphenhydramine is an antihistamine. It helps alleviate allergy symptoms like a runny nose, sneezing, and itching by preventing histamine from binding to its receptors.
Paracetamol/Acetaminophen is an analgesic and antipyretic. It reduces pain and fever by inhibiting the synthesis of prostaglandins in the central nervous system.
Phenylephrine is a decongestant. It reduces swelling and congestion by narrowing the blood vessels in the nasal passages.
