Dosage: Simple, Safe Rules for Taking Medication Correctly

Getting the dose right matters more than you think. A small timing change, a wrong measuring tool, or doubling up can turn a helpful drug into a problem. This page gives short, useful advice you can use today and points you to detailed posts on specific drugs like prasugrel, Dilantin, and venlafaxine.

Everyday rules for dosing

Follow the label and your prescriber. That sounds obvious, but people swap times, split pills, or skip the fine print. Read the label for dose amount, how often, route (oral, nasal, injection), and special instructions like "take with food." If the label and your doctor disagree, call the prescriber or pharmacist before changing anything.

Measure liquids with the right tool. Kitchen spoons vary—use the syringe or dosing cup that comes with the medicine. For infants and small kids, a syringe is best for accuracy. If you buy an oral syringe separately, get one marked in milliliters (mL).

Don’t double up after a missed dose unless told to. Many meds have specific rules for missed doses. Some say take it as soon as you remember; others say skip and wait. Doubling can cause harm, especially with blood thinners, heart meds, or strong pain relievers.

Be careful splitting pills. Not all tablets are scored or safe to split. Extended-release or coated pills should never be cut—doing so can release the drug too fast. Use a pill cutter for clean splits when appropriate.

When dosing needs extra care

Adjustments happen. Older adults, people with kidney or liver issues, and children often need lower doses. If you have reduced kidney or liver function, your doctor may change timing or amount. Don’t try to guess—ask for testing and guidance.

Watch for interactions. Some drugs change how others work. For example, certain antidepressants and antiplatelet drugs require dose checks and timing changes. Tell your provider about every prescription, over-the-counter drug, and supplement you take.

Store meds properly. Heat, light, and humidity can change a drug’s strength. Keep pills in the original container unless your provider or pharmacist suggests otherwise. Some meds require refrigeration—check the label or the product page on our site for storage tips.

Keep a simple log. If you take several medicines, a one-page daily checklist reduces mistakes. Note dose, time, and any side effects. Bring the log to appointments so your prescriber sees what actually happened.
