Many critics of god vine have pointed out these side effects as a reason to avoid using the herb but for those taking methotrexate these possible side effects might not sound so bad. According to rheumatology.org,

The most common side effects of methotrexate include nausea or vomiting and abnormalities in liver function tests…About 1-3% of patients develop mouth sores (called stomatitis), rash, diarrhea, and abnormalities in blood counts. Methotrexate may cause cirrhosis (scarring) of the liver, but this side effect is rare and most likely to occur in patients who already have liver problems or are taking other drugs that are toxic to the liver. Lung problems (persistent cough or unexplained shortness of breath) can occur when taking methotrexate. These side effects are more common in people with poor lung function. Persistent cough or shortness of breath should be reported to your doctor. Slow hair loss is seen in some patients, but hair grows back when the person stops taking this medication. Methotrexate can increase the sensitivity of the skin to sunlight, so limiting sun exposure and the use of sunscreen is advised.
