Hello, Your husband was on Levaquin for a long period of nine months for injured leg. Presently, he is having nausea and vomiting, sharp pain across his right side. He has lost appetite and is not taking food properly. He may be suffering from side effects of Levaquin that he has taken for a long periods. People with liver problems should avoid taking Levaquin as it can trigger symptoms of nausea and vomiting. Other symptoms may be constipation, diarrhea, dyspepsia, abdominal pain, flatulence, headache, insomnia, joint pain, leg pain, exhaustion, etc. You are suggested to get him clinically examined by a GP, get liver function tests, urinalysis, CBC, blood works and imaging tests to detect increased liver enzymes, hepatomegaly or biliary obstruction, etc. He will be treated accordingly. Help him stay away from addictions if any. The other side effects of Levaquin are tendonitis, peripheral neuropathy, polyneuropathy, dyspnea, light headedness, difficulty sleeping, agitation, confusion, muscle weakness in people with myasthenia gravis, etc. You are suggested to give boiled, well cooked food to your husband in small amount multiple times a day for a couple of months. Avoid giving him fried food, oily food, red meat, trans fat, full fat dairy products, refined flour, etc. He can take berries, fruits veggies that are well cooked. Give him food that is good for the liver. He can take liver tonic as a supplement. He can take lean meat and small fish. Take care. Hope I have answered your question.
