What is Allegra?

You have sneezing, runny nose, and itchy, watery eyes. This can only mean one thing: When these allergies strike, you may consider using an over-the-counter OTC medication to ease your symptoms. Allegra and Zyrtec are two commonly used allergy drugs. Both are available in prescription forms, as well, but this article only covers the OTC versions. The main active ingredient in Allegra is fexofenadine. The main active ingredient in Zyrtec is cetirizine. Both of these drugs are antihistamines.

Antihistamines work by blocking a substance called histamine in your body. Histamine is known for causing allergic symptoms. Blocking it helps prevent symptoms of seasonal allergies or hay fever. Allegra and Zyrtec are available over-the-counter in many forms. The table below details the forms and the approved age ranges. For specific dosage information on either drug, read the product package carefully or talk to your doctor. Remember to read the product label carefully.

Many OTC cold and allergy drugs contain the same active ingredients, so taking them together with Allegra or Zyrtec could lead to an overdose of these ingredients. Also, take Allegra or Zyrtec around the same time each day. This can ensure that you have just enough medication in your system to prevent allergies while also reducing the risk of side effects. Allegra and Zyrtec may cause mild side effects that may go away as your body gets used to the drug.

Most of these do not call for medical attention. But tell your doctor if any side effects are especially bothersome or do not go away. If you have serious side effects, call your doctor. Either one can affect the way the other medications work in your body. These interactions can increase or decrease the effect of the other medications or of Allegra or Zyrtec.

These antacids contain aluminum and magnesium, which can prevent your body from absorbing enough Allegra. This can make Allegra less effective. By taking your antacid at a different time from when you take Allegra, you can reduce this interaction. Allegra and Zyrtec may also not be safe for people with certain health issues. For example, you should talk to your doctor about how safe it is to use Allegra or Zyrtec if you have kidney disease.

If you have liver disease, you should also talk to your doctor before using Zyrtec. You should not take Allegra with fruit juice. Fruit juices such as grapefruit juice, orange juice, and apple juice can decrease the amount of Allegra that your body absorbs. This can make the drug less effective.

Do not take with fruit juices such as apple, grapefruit, or orange since they may decrease the absorption of this drug. As suggested by Shehnaza et al , various sites of the molecule are thought to be responsible for this interaction, including the piperidine nitrogen, the carboxylic acid -COOH group, and both hydroxyl -OH groups.
