How It Works

How It Works

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.

Side Effects

Side Effects

Common Reactine side effects may include:

  • Drowsiness or fatigue
  • Dry mouth
  • Headache
  • Dizziness
  • Sore throat

Serious side effects (rare):

  • Rapid or irregular heartbeat
  • Severe allergic reactions (rash, itching, swelling)
  • Difficulty urinating
  • Severe dizziness or fainting

Note: Contact your healthcare provider if you experience any serious symptoms or unusual eye changes.

Warnings

  • Drowsiness: Reactine can sometimes make you feel drowsy or sleepy. If this happens, avoid driving or doing anything that needs your full attention.
  • Alcohol: Drinking alcohol while using Reactine can make you feel more tired or dizzy. It’s a good idea to limit or avoid alcohol while taking this medication.
  • Kidney and Liver Health: If you have kidney or liver issues, talk to your doctor before taking Reactine, as it could affect how your body processes the medication.
  • Pregnancy and Breastfeeding: If you’re pregnant or breastfeeding, check with your doctor to see if Reactine is safe for you.
  • Other Medications: If you’re taking other medications, let your doctor know, as some drugs may interact with Reactine and cause unwanted side effects.

Do Not Overuse: Stick to the recommended dose of Reactine. Taking more than the prescribed amount can lead to unwanted side effects.
