Telfast (fexofenadine) has not been linked to instances of clinically apparent acute liver injury. It is considered to have minimal adverse effects on the liver because only about 5% of the dosage is metabolized by the liver, with most of it being excreted unchanged.
Fexofenadine use is not generally associated with liver enzyme elevations but terfenadine, a second generation antihistamine that is metabolized in part to fexofenadine, was the attributed cause of several reported cases of clinically apparent liver injury.
The nonsedating antihistamines, however, are often used for an extended period and several forms have been linked to rare instances of clinically apparent acute liver injury which has generally been mild and self-limiting; the antihistamines most commonly linked to liver injury have been cyproheptadine, cetirizine and ...
Here are 10 medications that in some instances can hurt the liver, plus ways to help protect it from damage.
If you're using oral antihistamines very often, you might have wondered if it's OK to keep relying on antihistamines to control symptoms of allergies. The good news is there's no research evidence to suggest regular, long-term use of modern antihistamines is a problem.
Fexofenadine (Allegra)
It's one of the least sedating second-generation antihistamines, making it a safe option for long-term use if you take it as your doctor prescribes.
Take Telfast for up to 5 days, if necessary. If symptoms persist after 5 days, consult your Doctor or Pharmacist. Take Telfast with a glass of water to make it easier to swallow. Telfast may be taken with or without food.
For liver repair and support, focus on hydration with water, green tea, and coffee, plus juices from blueberries, cranberries, grapefruit, or beetroot, all rich in antioxidants that fight damage and inflammation, but avoid alcohol and sugary drinks that stress the liver.
Some of the most common symptoms of drug induced liver injury are:
Chemicals that are especially toxic for the liver include:
Itching in liver disease can vary from mild to exhausting. If your itching is caused by a liver problem, there won't be a skin rash or an insect bite. But constant scratching can damage the skin. The more severe the disease, the worse the itching gets.
We found that higher blood levels of histamine are associated with circulatory dysfunction and the development of acute-on-chronic liver failure and death in patients with cirrhosis.
If liver damage is the cause of elevated liver enzymes, you may have symptoms such as:
Although most people will not experience any, some of the side effects that may occur with Telfast® are:
Telfast 180 mg tablets contain fexofenadine, a powerful antihistamine that helps relieve severe allergy symptoms such as sneezing, itching, watery eyes, runny nose, and nasal congestion. It is non-drowsy and provides long-lasting relief, making it ideal for those with persistent allergies.
Early signs your liver is struggling often include persistent fatigue, unexplained weight loss, loss of appetite, nausea, abdominal pain/bloating (especially upper right), and itchy skin, with changes in urine/stool color and easy bruising also being key indicators, though sometimes symptoms are absent in early stages. Pay attention to changes like dark urine, pale stools, or jaundice (yellow skin/eyes), as these signal the liver isn't filtering toxins or processing bilirubin properly.
Acetaminophen or Tylenol® is the best known medication that can damage the liver. This medication is widely available without prescription and is present in many of the cold and flu remedies as well as in prescribed pain medications.
The three worst things for your liver are excessive alcohol, a diet high in added sugars, unhealthy fats, and salt (processed/fast foods), and overuse of certain medications (like acetaminophen/paracetamol), all leading to fat buildup (fatty liver), inflammation, and potential severe damage like cirrhosis, though lifestyle changes can often reverse early stages.
The fastest way to repair your liver involves immediate lifestyle changes: stop alcohol/smoking, adopt a healthy diet (whole foods, less sugar/fat/processed items), manage weight/exercise, and avoid liver-harming medications, all while consulting a doctor for personalized guidance, as severe damage needs medical intervention for reversal.
When symptoms do occur, they may first include fatigue; weakness and weight loss; nausea; bruising or bleeding easily; swelling in your legs, feet or ankles; itchy skin; redness on the palms of your hands; and spider-like blood vessels on your skin.
Drink enough water
Staying hydrated is crucial for your physical health, and your liver health is no exception. Drinking enough water helps your liver flush out toxins and function properly. It can also: Support nutrient absorption.
If you're using oral antihistamines very often, you might have wondered if it's OK to keep relying on antihistamines to control symptoms of allergies. The good news is there's no research evidence to suggest regular, long-term use of modern antihistamines is a problem.
But when people stop taking antihistamines, they experience a withdrawal reaction. This occurs because the body has become dependent on the medication and will experience withdrawal symptoms when it's no longer present.
What is the difference between Telfast® 120 and Telfast® 180? Telfast® 120mg is indicated for the relief of symptoms of seasonal allergic rhinitis in adults and children over 12 years of age. Telfast® 180mg is indicated for the relief of itching that occurs with hives in adults and children over 12 years of age.
Tolerance is not a problem. Rarely, they can cause acute self-limited liver injury. One study has reported a more serious long-term effect, a 3.5-fold increase in the risk of gliomas, a common type of brain tumor in patients with long-term antihistamine use for allergic conditions.
