Hi, Tonact TG20 is a medication used to lower cholesterol and triglyceride levels in the blood. It contains two active ingredients, atorvastatin, and fenofibrate. Both these drugs work by reducing the production of cholesterol and triglycerides in the liver. Like any medication, Tonact TG20 can have potential side effects. Common side effects include headache, muscle pain, joint pain, nausea, vomiting, diarrhea, and abdominal pain. These side effects are usually mild and go away on their own as your body gets used to the medication. However, there are some rare but serious side effects associated with Tonact TG20, such as liver damage and muscle breakdown. Symptoms of liver damage include yellowing of the skin and eyes, dark urine, and abdominal pain. Muscle breakdown can cause severe muscle pain, weakness, and dark urine. If you experience any of these symptoms, you should immediately stop taking the medication and consult a doctor. Regarding the concern about Tonact TG20 affecting sexual desire, there have been reports of such side effects with atorvastatin, one of the active ingredients in Tonact TG20. However, these side effects are very rare, and most people do not experience any sexual problems while taking this medication. In summary, Tonact TG20 is generally safe and effective in lowering cholesterol and triglyceride levels. However, as with any medication, it may cause some side effects, which you should discuss with your doctor. Take care. Hope I have answered your question. Let me know if I can assist you further.
