How often do you take claritin?

Allergic reactions can be unbearable, especially when they are seasonal. One of the most popular solutions to this problem is Claritin, an antihistamine that has been in the market for years. But the question is, how often should you take Claritin? In this article, we will delve deeper into the topic and give you all the information you need to know.

The basics of Claritin

Before we get into the dosage and frequency of Claritin, let’s first understand what it is and how it works. Claritin contains loratadine, an antihistamine that works by blocking the histamine, a chemical released by your immune system that causes allergy symptoms such as sneezing, itching, and a runny nose.

Is Claritin ideal for everyone?

While Claritin can be an excellent solution for seasonal allergies, it is not for everyone. It is essential to consult a doctor before taking Claritin if you are pregnant, nursing, have liver or kidney disease, or are taking other medications.

The Dosage of Claritin

The recommended dosage of Claritin differs depending on several factors such as age, health, and the form of Claritin you are taking. The most common form of Claritin is in tablets, while others come in capsules and syrup.

For Adults and Children twelve years and older:

  • 10mg of Claritin tablet once per day
  • 10ml (two teaspoons) of the syrup once per day
  • One capsule of Claritin once per day

For Children between two to eleven years old:

  • 5mg of Claritin syrup once per day
  • 5ml (one teaspoon) of the syrup once per day
  • The tablet form is not recommended for children below the age of six.

Taking Claritin with food

Claritin can be taken with or without food. However, it is advisable to take it with water and food to prevent an upset stomach. Also, avoid taking Claritin with grapefruit juice as it can alter its effectiveness.

When is the best time to take Claritin?

The time you can take Claritin varies based on how your body responds to it. Some people prefer taking it in the morning to start their day off allergy-free, while others find taking it at night helps them sleep better. However, the essential thing to understand when taking Claritin is that you need to take it consistently to feel the full effects. Remember, Claritin can take up to two weeks to be fully effective.

What are the common side effects of Claritin?

Like all medications, Claritin can cause side effects. Some of the common side effects of Claritin include:

Nervous system: headaches, drowsiness, dizziness, fatigue, and insomnia.

Gastrointestinal system: Dry mouth, nausea, and stomach pain.

It is essential to contact your doctor if you experience severe side effects after taking Claritin.


Claritin can be an incredible solution for seasonal allergies if taken in the correct dosage and frequency. Remember to talk to your doctor to determine if Claritin is right for you, and don’t forget to take it consistently to feel the full effects. By doing so, you can feel confident that your allergy symptoms will be under control.
