Symptoms of Too Much Antihistamine
Taking too much antihistamine can lead to a range of uncomfortable and potentially dangerous symptoms. Common signs of an overdose of antihistamine include:
Drowsiness: Taking too much antihistamine can lead to excessive drowsiness and even sedation. This can be dangerous for activities that require alertness, such as driving or operating machinery.
Nausea and Vomiting: Too much antihistamine can also cause nausea and vomiting. This can lead to dehydration and electrolyte imbalances, especially in young children.
Confusion: Overdosing on antihistamines can lead to confusion, disorientation, and difficulty concentrating.
Agitation: Taking too much antihistamine can lead to agitation and restlessness.
Rapid Heartbeat: An overdose of antihistamine can lead to a rapid heartbeat (tachycardia). This can cause serious complications if left untreated.
Dry Mouth: Too much antihistamine can cause excessive dryness in the mouth, leading to difficulty swallowing and speaking.
Blurred Vision: Taking too much antihistamine can lead to blurred vision and other vision problems.
Seizures: In rare cases, taking too much antihistamine can lead to seizures. This is especially dangerous and should be treated as a medical emergency.
