Make sure to read the small print in drug commercials
The "small print" in prescription drug commercials isn't actually hidden—it's usually spoken quickly or displayed briefly during what's called the major statement of risks. The scariest parts are often rare, but they're included because the risks can be serious.
Some of the most alarming warnings commonly heard include:
- Death:
Some medications carry warnings about an increased risk of death in
certain patients. For example, some antipsychotics have a boxed warning
about increased mortality in elderly patients with dementia-related
psychosis.
- Suicidal
thoughts and behavior: Many antidepressants, seizure
medications, and other drugs warn about an increased risk of suicidal
thinking, especially in children, adolescents, and young adults.
- Life-threatening
infections: Drugs that suppress the
immune system (such as those for rheumatoid arthritis, psoriasis or
inflammatory bowel disease) may increase the risk of tuberculosis, fungal
infections, and other serious infections.
- Cancer:
Some immune-modulating drugs carry warnings about an increased risk of
certain cancers, such as lymphoma or skin cancer.
- Heart
attack, stroke, and blood clots: Some
hormone therapies, migraine medications, and other drugs warn of increased
cardiovascular risks in certain populations.
- Liver
failure: Certain medications can cause severe
liver damage, sometimes requiring a transplant.
- Severe
allergic reactions: Commercials often mention
anaphylaxis, which can be fatal if not treated immediately.
- Stevens-Johnson
syndrome and toxic epidermal necrolysis:
These are rare but potentially fatal skin reactions that cause widespread
blistering and skin loss.
- Birth
defects: Some medications should never be
taken during pregnancy because they can cause serious fetal harm.
Why do they sound so frightening?
The U.S. Food and Drug Administration
requires that prescription drug advertisements present a balanced view of
benefits and risks. Even if a serious side effect occurs in only a tiny
percentage of patients, it may still need to be disclosed because the consequences
are severe.
It's also important to remember that:
- Many
of the listed side effects are very rare.
- The
warnings often apply only to people with specific medical conditions or
who take certain other medications.
- The
potential benefits of the drug may outweigh the risks for the patients
it's intended to treat.
What should you pay attention to?
Rather than focusing on the long list of rare events, listen for:
- Who
should not take the drug.
- The
most common side effects.
- Symptoms
that require immediate medical attention.
- Drug
interactions and monitoring requirements.
The most dramatic-sounding warning in a commercial isn't necessarily the one most likely to affect you. Your healthcare provider can help interpret how those risks apply to your individual health, age, and medical history.
