Taking a pill, using an inhaler, or measuring a liquid sounds straightforward. But small mistakes — wrong timing, mixing with alcohol, or skipping directions — can cut effectiveness or cause harm. This page gives short, practical rules you can use right away so your meds work like they should.
First, read the label and the leaflet. The label tells dose, timing, and any food instructions. The leaflet often lists side effects and interactions. If the directions differ from what your doctor said, ask the prescriber or pharmacist. Don’t guess.
Know the exact dose. Measure liquids with the syringe or cup that comes with the medicine — kitchen spoons are inaccurate. For tablets, only split pills if the tablet is scored and your doctor says it’s okay. Crushing or splitting some drugs changes how they’re absorbed.
Timing matters. Some drugs work best on an empty stomach (take 1 hour before or 2 hours after a meal). Others need food to prevent nausea or to be absorbed properly. For example, many antibiotics and some heart meds have clear rules — follow them. For chronic meds that control blood pressure, sugar, or mood, take them at the same time every day to keep steady levels in your body.
Inhalers and nebulizers: shake inhalers, breathe out fully, seal lips, press and inhale slowly, then hold your breath for 5–10 seconds. For nebulizers, sit upright and breathe slowly until the cup is empty. If you use a steroid inhaler, rinse your mouth afterward to lower the risk of thrush.
Topical patches and creams: apply to clean, dry skin and rotate sites for patches. Write the time and date on a patch before applying. For eye or ear drops, tilt your head back and keep the dropper clean — don’t touch your eye.
Missed doses: short-acting meds — take missed dose as soon as you remember unless it’s almost time for the next one. Don’t double up. For long-acting or blood-thinning drugs, get specific advice from your provider before altering doses.
Watch for interactions. Tell your doctor about all prescription drugs, over-the-counter meds, herbal supplements, and alcohol use. Some antidepressants, antifungals like Diflucan, or blood pressure drugs can change how other medicines act. If you start a new symptom, review recent medication changes first.
Storage and disposal matter. Keep meds in original containers, away from heat and moisture unless the label says otherwise. Some drugs need refrigeration. Dispose of expired or unused medicines safely — many pharmacies have take-back programs.
Finally, ask questions. If side effects bother you, if a pill tastes odd, or if you’re unsure how to take a new prescription, call your pharmacist or doctor. Small questions now prevent bigger problems later.
Use these simple steps to get the most from your treatment and stay safe while taking medicine.
