What to do if you miss a dose

Almost everyone forgets a dose sometimes. What to do depends on the medicine and how long it's been — so the safest first step is often to check the label or ask your pharmacist. Here's general guidance.

General rule of thumb

• If you remember soon after the missed time, you can often take it then.
• If it's almost time for the next dose, it's usually best to skip the missed one and continue as normal.
• Do not double up to "catch up" unless your pharmacist or the label says it's okay — doubling can cause side effects or harm.

When timing matters most

Some medicines are more sensitive to missed or late doses, including:

• Parkinson's medicines (like levodopa), where timing affects how you move.
• Blood thinners and heart-rhythm medicines.
• Insulin and diabetes medicines.
• Certain HIV, transplant, and seizure medicines that need steady levels.
• Antibiotics, where finishing the full course matters.

Prevent missed doses

• Use a pill organizer or blister pack.
• Set phone alarms or reminders for each dose.
• Tie doses to daily routines (meals, brushing teeth).
• Refill before you run out.
