Questions to Ask Your Pharmacist

Generic Medications Are Equally EffectiveGeneric medications contain the same active ingredient at the same dose as brand-name equivalents and undergo rigorous testing to demonstrate equivalent effectiveness — cost differences don't reflect quality or efficacy differences.
Can I take my medication at a different time than prescribed if it's more convenient?
For many medications, some flexibility is fine, but for others (especially those requiring consistent blood levels like levothyroxine, or timed around meals), sticking closely to instructions matters — ask your pharmacist about your specific medication.
What should I do with leftover or expired medications?
Return unused or expired medications to your pharmacy for safe disposal — don't flush them down the toilet or put them in household rubbish, as this can harm the environment.
