Alatrofloxacin and trovafloxacin may cause liver problems, including liver failure, at any time during treatment in a small number of people who are treated with these medicines. Check with your doctor immediately if you notice that your urine has become dark or your skin or eyes are yellow in color or if you experience loss of appetite, nausea or vomiting, severe abdominal pain, or unusual tiredness or weakness. These may be possible signs or symptoms of a liver problem.
If you are taking aluminum- or magnesium-containing antacids, citric acid buffered with sodium citrate (e.g., Bicitra), iron supplements or vitamins, intravenous morphine, or sucralfate, do not take them at the same time that you take trovafloxacin tablets. It is best to take these medicines at least 2 hours before or 2 hours after taking trovafloxacin. These medicines may keep trovafloxacin tablets from working properly.
Some people who take alatrofloxacin or trovafloxacin may become more sensitive to sunlight than they are normally. Exposure to sunlight, even for brief periods of time, may cause severe sunburn or skin rash, redness, itching, or discoloration. When you begin taking this medicine:
- Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.
- Apply a sun block product that has a skin protection factor (SPF) of at least 15. Some patients may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your health care professional.
- Do not use a sunlamp or tanning bed or booth.
If you have a severe reaction from the sun, check with your doctor.
Alatrofloxacin or trovafloxacin may cause some people to become dizzy, lightheaded, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert. If these reactions are especially bothersome, check with your doctor.
