Overview

Introduction

Allegra 120mg Tablet belongs to a group of medicines called antihistamines. It is used to treat various allergic conditions such as hay fever, conjunctivitis and some skin reactions such as eczema, hives and reactions to bites and stings. It also relieves watery eyes, runny nose, sneezing, and itching.

Allegra 120mg Tablet should be taken on an empty stomach. The dose may vary depending on what you are taking it for. Take it as prescribed by your doctor. You may need this medicine only on days you have the symptoms, or you may need to take it every day to prevent the symptoms from happening. If you stop taking it earlier than advised, your symptoms may come back.

This medicine is generally very safe. The most common side effects include headache, drowsiness, dizziness, and nausea. These are usually mild and go away after a couple of days as your body adjusts. Consult your doctor if any of the side effects persist or worry you.

Before taking it, tell your doctor if you have any problems with your liver or kidneys or with your heart as antihistamines can cause your heart to beat faster. Pregnant or breastfeeding women should also consult with their doctor before taking it. Avoid drinking alcohol as it can cause excessive drowsiness with this medicine. It usually does not impair your ability to drive, but you should not drive if it makes you feel sleepy or dizzy.

Common
  • Headache
  • Drowsiness
  • Nausea
  • Dizziness

How to cope with side effects?

The occurrence of side effects varies from person to person. The following are a few ways of dealing with some of the common side effects. However, consult your doctor if these persist.

  • Coping with Headache
    Make sure you rest and drink plenty of fluids. Rest in a quiet, dimly lit room. Do not sleep more than you normally would. Do not strain your eyes (for example by looking at a screen). Do not drink alcohol. Headaches are usually temporary and usually go away with time. But, if they last longer or get worse, ask your doctor to recommend a painkiller.
  • Coping with Drowsiness
    If the medicine is making you drowsy during the day, stop what you are doing and sit or lie down until you feel better. You can also consider taking a nap. Physical exercises such as walking may be helpful. Do not drink alcohol, as it will make you feel more tired. Avoid driving or operating heavy equipment when you are feeling drowsy. This problem usually goes away as your body gets used to the medicine. However, if it does not, ask your doctor if you can take your medicine at bedtime or whether the dose can be reduced.
  • Coping with Nausea
    You can help yourself by eating small, frequent meals rather than large ones and drinking plenty of fluids. Eat slowly. Avoid fatty, fried, spicy and very sweet foods. Eat cold or slightly warm food if the smell of cooked or cooking food makes you feel sick. Get plenty of fresh air. You could also try chewing ginger or drinking ginger tea. Eat bananas to replace potassium in your blood which can drop if you are sick (vomit). Use oral rehydration salts to replace vitamins and minerals lost through being sick. There are some medicines that can help you stop from feeling sick. Speak to your doctor if your condition does not improve.
  • Coping with Dizziness
    This is usually short-lived and should go away within a few days. If this happens, stop what you are doing and sit or lie down until you feel better. Lying still in a dark, quiet room may help reduce the spinning feeling. Sleep with your head slightly raised on two or more pillows. Get up slowly from a lying or sitting position. Get plenty of rest and try to relax as being anxious can make it worse. Try taking this medicine at bedtime to reduce the symptoms. Drinking plenty of water and ginger tea may also help. Avoid alcohol, caffeine and smoking as it will make you feel worse. Avoid driving or using tools or machinery until you feel better.

How to use Allegra Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Allegra 120mg Tablet is to be taken empty stomach.
