Frequently Asked Questions

Generic medications contain the same active ingredient, strength, dosage form, and route of administration as their brand-name counterparts. The FDA requires generics to be bioequivalent, meaning they work the same way in your body. Generics are typically much less expensive because manufacturers don't have to repeat the original clinical trials.

Taking a medication with food means swallowing it during or right after a meal. This is usually recommended to reduce stomach upset or to help your body absorb the medication more effectively. If you're unsure, a small snack like crackers or a glass of milk is usually sufficient — you don't need a full meal.

Not all pills can be safely cut or crushed. Extended-release, enteric-coated, or capsule medications should never be altered unless your pharmacist or doctor specifically says it's safe. Crushing these can release the full dose at once, which may be dangerous. Always ask your pharmacist before modifying any medication.

If you miss a dose, take it as soon as you remember — unless it's almost time for your next scheduled dose. In that case, skip the missed dose and continue your regular schedule. Never double up to make up for a missed dose. For critical medications like blood thinners or antibiotics, contact your doctor or pharmacist for specific guidance.

Check the expiration date printed on the bottle, box, or blister pack. Expired medications may lose potency or, in rare cases, become harmful. Do not use medications past their expiration date. Dispose of them safely using a drug take-back program or by following FDA disposal guidelines.

A drug interaction occurs when one medication affects how another medication works in your body. Interactions can make a drug less effective, increase its side effects, or sometimes cause dangerous reactions. Interactions can also happen between medications and certain foods, beverages (like grapefruit juice or alcohol), or supplements.

Not always. Common OTC medications like ibuprofen, aspirin, antacids, and antihistamines can interact with prescription drugs. Always tell your doctor and pharmacist about every medication, vitamin, and supplement you take — including OTC products. Use MedTrack's Interaction Checker to screen for potential conflicts.

Alcohol can interact with many medications, including pain relievers, antibiotics, antidepressants, sleep aids, and blood thinners. These interactions can range from mild (drowsiness) to serious (liver damage, dangerous drops in blood pressure). Always read your medication guide and ask your pharmacist if alcohol is safe with your specific medications.

Side effects vary widely by medication, but common ones include nausea, dizziness, headache, dry mouth, fatigue, and changes in appetite. Serious side effects — such as difficulty breathing, chest pain, severe rash, or swelling of the face — require immediate medical attention. Always read the medication guide that comes with your prescription.

You can transfer most prescriptions by calling or visiting your new pharmacy and providing your current pharmacy's name and phone number. The new pharmacy will contact your current pharmacy to transfer the prescription. Note that controlled substances (Schedule II) generally cannot be transferred — you'll need a new prescription from your doctor.

Most pharmacies allow refills when you have about a 7-day supply remaining (roughly 75–80% through your supply). For controlled substances, refill windows are stricter and vary by state law. Your insurance plan may also have its own refill timing rules. Check with your pharmacy for their specific policy.

A prior authorization (PA) is a requirement from your insurance company that your doctor must get approval before they'll cover a specific medication. Your doctor submits clinical information to justify why you need that particular drug. The process can take a few days to a few weeks. Ask your doctor's office to start the PA as early as possible.

Many insurance plans allow 90-day supplies for maintenance medications (drugs you take long-term for chronic conditions). This is often cheaper per dose and more convenient. Ask your doctor to write a 90-day prescription and check with your pharmacy or mail-order service about availability.

Most medications should be stored at room temperature (59–77°F / 15–25°C), away from heat, light, and moisture. Despite the name, the bathroom medicine cabinet is actually a poor choice due to humidity. A bedroom dresser drawer or a kitchen cabinet away from the stove and sink are better options. Some medications require refrigeration — check your label.

The safest option is a DEA-authorized drug take-back location — many pharmacies and police stations offer this service. If no take-back is available, most medications can be mixed with an undesirable substance (like coffee grounds or dirt), sealed in a bag, and placed in household trash. A few medications have specific FDA flush instructions due to their high abuse potential.

Yes. Extreme temperatures can degrade medications, making them less effective or even harmful. Avoid leaving medications in a hot car, near a sunny window, or in a freezing garage. Insulin, certain eye drops, and some liquid antibiotics are especially sensitive to temperature changes. Always follow the storage instructions on your medication label.
