Reactine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. By inhibiting histamine's effects, Reactine helps alleviate symptoms such as sneezing, itching, and a runny nose. It is a second-generation antihistamine, meaning it is less likely to cause drowsiness compared to first-generation antihistamines.
Common Reactine side effects may include:
Serious side effects (rare):
Note: Contact your healthcare provider if you experience any serious symptoms or unusual eye changes.
Do Not Overuse: Stick to the recommended dose of Reactine. Taking more than the prescribed amount can lead to unwanted side effects.
If you miss a dose of Reactine, take it as soon as you remember. However, if it's almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take extra medicine to make up for a missed dose.
Taking more than the recommended dose of Reactine can lead to symptoms such as drowsiness, rapid heartbeat, and dizziness. Seek immediate medical attention if you suspect an overdose.
