The following chart should only be used as a guide to help identify potential drug-related side effects. Some of these side effects have been reported in medical literature, others are purely anecdotal. Obviously, not everyone taking a drug will experience that drug's side effects.
Most side effects show up in only a modest percentage of the people using a drug.
Many people experience no obvious side effects, while others may experience several from the same drug. The manufacturers label, which is included with most prescriptions, typically lists how often different side effects have been seen in people participating in clinical trials. It's important to recognize that no drug should be evaluated solely based on the number or type of side effects listed. Some drugs may have a high number of minor side effects, or side effects which impact on a large percentage of users, while others may have few or infrequent, but much more serious side effects. There is seldom any way to predict what side effects will occur for an individual.
