Trental 400 Tablet is used to treat pain in the legs due to insufficient blood flow (intermittent claudication). It also reduces cramping, numbness, or weakness in the legs on walking in such patients. It works by decreasing the viscosity (thickness) of blood, allowing it to pass more easily through the blood vessels, especially in the small blood vessels of the hands and feet. It can also increase the distance you can walk without pain since it improves your legs blood circulation. It is recommended in patients whose pain has not improved even after lifestyle changes like quitting smoking and doing regular exercise. In some cases, it may cause side effects such as nausea, vomiting, diarrhoea, headache, lightheadedness, sleep problems, intrahepatic cholestasis (removal of bile from the liver is blocked), abdomen pain, constipation, and urine discolouration.

About Trental 400 Tablet

Trental 400 Tablet is a prescription medication used to improve blood circulation in patients with chronic blood vessel problems. It is primarily prescribed to treat intermittent claudication, which is muscle pain, cramping, or tiredness in the legs that happens during walking. By helping blood flow more easily through narrowed vessels, it helps reduce these uncomfortable symptoms and improves your mobility.

For this medication to work effectively, you need to take it consistently and exactly as your doctor prescribes, which is typically three times a day. It is highly recommended to take your tablets with meals to prevent stomach upset or nausea. Combining this treatment with daily lifestyle adjustments, such as a structured walking program and eating a heart-healthy diet, can greatly improve your results.

While taking Trental 400 Tablet , you may experience some common, mild side effects like a mild upset stomach, gas, or occasional dizziness. However, if you experience rare but serious symptoms like chest pain, an irregular heartbeat, or unusual bleeding, you must contact your healthcare provider immediately.

Talk to your doctor before starting Trental 400 Tablet if you have a history of kidney disease, liver damage, or heart problems. Do not take this medicine if you have recently had severe bleeding in your brain or retina, as it can increase the risk of severe blood loss.

This medication can interact with other substances; for example, smoking can decrease its effectiveness by further narrowing your blood vessels, while alcohol may increase your risk of dizziness. Additionally, if you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, you should discuss the risks and benefits with your doctor or pharmacist before starting treatment.
