A small percentage of the people who use antihistamines develop heart rhythm?

Antihistamines are medications used to treat allergies. They work by blocking the action of histamine, a chemical that is released by the body in response to an allergen. Histamine causes symptoms such as sneezing, runny nose, and itchy eyes.

Antihistamines are generally safe and well-tolerated. However, some people may experience side effects, such as drowsiness, dizziness, and dry mouth. In rare cases, antihistamines can cause heart rhythm problems.

The risk of developing heart rhythm problems from antihistamines is higher in people who have certain medical conditions, such as:

- Heart disease

- Diabetes

- Hypertension

- Kidney disease

The risk of developing heart rhythm problems is also higher in people who:

- Are over the age of 65

- Are taking other medications that can cause heart rhythm problems

- Have a family history of heart rhythm problems

If you are concerned about the risk of heart rhythm problems from antihistamines, talk to your doctor. They can help you decide whether or not antihistamines are right for you.

Here are some tips for reducing the risk of developing heart rhythm problems from antihistamines:

- Start with a low dose of antihistamine and gradually increase the dose as needed.

- Take antihistamines with food or milk to reduce the risk of stomach upset.

- Avoid taking other medications that can cause heart rhythm problems.

- If you have any concerns about the side effects of antihistamines, talk to your doctor.
