Bastab Tablets: Selective Histamine Antagonist for Allergies and Urticaria

Welcome to our new medical article about Bastab Tablets. In this article, we will provide a comprehensive overview of this medication used to treat allergies and urticaria. We will cover its ingredients, uses, precautions, and side effects.

Ingredients of Bastab Tablets

Bastab Tablets contain the active ingredient Ebastine at a concentration of 20 mg. Ebastine is a selective H1 histamine receptor antagonist, which is responsible for storing histamine in the body. It is important to note that Ebastine does not affect the central nervous system and does not possess anti-cholinergic effects.

Uses of Bastab Tablets

Bastab Tablets are prescribed for several conditions, including:

1. Seasonal or Perennial Allergic Rhinitis

Bastab Tablets are used to treat both seasonal and perennial allergic rhinitis, whether or not it is accompanied by allergic conjunctivitis. The typical dosage ranges from 10 to 20 mg once daily, depending on the severity of the condition.

2. Chronic Urticaria

Bastab Tablets can also be used to treat chronic urticaria, a condition characterized by skin itching. The dosage in this case also depends on the severity of the disease and ranges from 10 to 20 mg daily.


Despite the benefits of Bastab Tablets, there are some contraindications to their use, including:

  • Do not use in case of severe hypersensitivity to Ebastine or any of the drug’s components.
  • Do not use in case of severe liver dysfunction.

Use in Children

The effectiveness and safety of Ebastine in tablet form have not been verified for children under 12 years old. Therefore, it is strongly advised to consult a doctor before using it for children.


As with other antihistamines, there are certain warnings to consider when using Ebastine in specific conditions:

  • Heart rhythm disorders such as long QT syndrome.
  • Use of medications that lead to QT interval prolongation or inhibit the cytochrome CYP3A4 enzyme system, such as azole antifungals and macrolide antibiotics.
  • Low blood potassium levels.

If there is any uncertainty about the suitability of using Bastab Tablets, it is always recommended to consult a doctor.

Pregnancy and Breastfeeding

The safety of using Bastab Tablets during pregnancy or breastfeeding has not been studied. Therefore, it is strongly advised not to use it during these periods without consulting a specialized doctor.

Side Effects

Clinical studies have shown that some patients may experience certain side effects while taking Bastab Tablets. These side effects may include:

  • Headache.
  • Dry throat.
  • Drowsiness.

It is worth noting that these side effects have appeared at rates similar to the placebo (ineffective drug).

Drug Interactions

There are certain medications that should be avoided when taking Bastab Tablets, as they can lead to undesirable drug interactions. These medications include:

  • Ketoconazole.
  • Erythromycin.

Both of these are known to prolong the QT interval. To avoid these interactions, it is essential to inform your doctor of the medications you are taking.

Special Storage Precautions

To maintain the effectiveness and safety of Bastab Tablets, special storage precautions should be followed, including:

  • Store at temperatures below 30 degrees Celsius.
  • Keep out of the reach of children.
