Conclusion
If you are gaining weight and suspect that your current
medications may be the cause, it is important that you
do not stop taking the drug or switch to a lower dosage
without first speaking to your doctor. Stopping or changing
your medication may result in a potentially serious health
condition going untreated, which may put your health at
risk.
In most cases, there are other medications available that
your doctor can switch you to that offer the same beneficial
effect but will not cause excess weight gain. If the drug
cannot be switched, then your doctor can provide you
with advice on diet changes that might help and will likely
encourage you to increase your aerobic exercise to offset
any weight changes.
