I did a quick look-up on Fosamax. I didn't see liver problems mentioned (maybe someone else here can find some additional info for you). I'll paste here what I did find on Fosamax:
The following came from Medscape:

Next came from Mayo Clinic:
Alendronate (a-LEN-dro-nate) is used to prevent or treat osteoporosis (thinning of the bone) in women after menopause and to treat osteoporosis in men. It may also be used to treat Paget's disease of bone and osteoporosis (thinning of the bone) caused by glucocorticoid treatment.
Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For alendronate, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to alendronate. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Make certain your health care professional knows if you are on any special diet, such as a low-sodium or low-sugar diet. Your doctor may recommend that you eat a balanced diet with an adequate amount of calcium and vitamin D (found in milk or other dairy products).
Alendronate has not been studied in pregnant women. However, studies in animals have shown that alendronate causes birth defects and other pregnancy problems. Before taking this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking alendronate, it is especially important that your health care professional know if you are taking the following:
Aspirin or products that contain aspirin Use with alendronate may cause or make esophagus, intestine, or stomach problems worse
Other Medical Problems
The presence of other medical problems may affect the use of alendronate. Make sure you tell your doctor if you have any other medical problems, especially:
Digestion problems (Taking alendronate may be harmful to the esophagus, intestine, or stomach)
Esophagus problems or
Intestine problems or
Stomach problems Alendronate may make these conditions worse
Kidney problems The effects of alendronate may be increased
Proper Use Of This Medicine
Take alendronate with a full glass (6 to 8 ounces) of plain water on an empty stomach . It should be taken in the morning at least 30 minutes before any food, beverage, or other medicines. Food and beverages, such as mineral water, coffee, tea, or juice, will decrease the amount of alendronate absorbed by the body. Waiting longer than 30 minutes will allow more of the drug to be absorbed. Medicines such as antacids or calcium or vitamin supplements will also decrease the absorption of alendronate.
Do not lie down for 30 minutes after taking alendronate . This will help alendronate reach your stomach faster. It will also help prevent irritation to your esophagus.
Your doctor may recommend that you eat a balanced diet with an adequate amount of calcium and vitamin D (found in milk or other dairy products). However, do not take any food, beverages, or calcium or vitamin supplements within 30 minutes or longer of taking alendronate. To do so may keep this medicine from working properly.
