Pharmacists answer medication questions every day. Here are some of the most commonly asked questions—and the reasons behind them.
1. Should I Take My Medication With Food?
Some medications work best with food, while others should be taken on an empty stomach. Always follow the directions on the prescription label.
Why do some medications need to be taken with food?
One reason is to help reduce stomach irritation and side effects. Certain medications can cause nausea, upset stomach, or even stomach ulcers when taken on an empty stomach. Having food in the stomach acts as a protective buffer and may improve tolerability.
Why do some medications need to be taken on an empty stomach?
For some medications, such as levothyroxine, food can interfere with absorption and prevent your body from receiving the intended dose. Taking these medications on an empty stomach allows them to be absorbed more efficiently, helping them work as effectively as possible.
If you're unsure whether your medication should be taken with food, ask your pharmacist for guidance.
2. What Should I Do If I Miss a Dose?
Do not automatically double your next dose. Depending on the medication, different instructions may apply. In some cases, taking two doses too close together may increase the risk of side effects or even be dangerous. If you miss a dose and are uncertain about what to do, contact your pharmacist or healthcare provider for individualized advice.
3. Can I Cut My Tablets in Half?
Some tablets may be safely split, while others should never be cut, crushed, or chewed.
In general, tablets that have a score line in the middle are often designed to be split in half. However, this is not always the case.
Why can't certain pills be split or crushed?
The way a medication is manufactured plays an important role in how it works. Some tablets have special coatings or extended-release mechanisms that control how quickly the medication is released and absorbed in the digestive tract.
Breaking or crushing these medications can alter their intended absorption, causing the medication to work too quickly, too slowly, or less effectively than intended. In other words, the tablet's structure has been scientifically designed to deliver the medication in the safest and most effective way possible.
Before splitting any medication, ask your pharmacist whether it is safe to do so.
4. Is It Safe to Take Vitamins With My Prescriptions?
Certain vitamins, minerals, and supplements may interact with prescription medications.
Why are drug interactions important?
The goal of medication therapy is to achieve the right amount of medication in your body. Some supplements may increase the effects of a medication, leading to higher drug levels and potentially more side effects. Others may decrease absorption or reduce the effectiveness of a medication.
Taking medications at their appropriate doses is essential for maintaining well-being and achieving the health goals established by your physician.
This is why it is important to inform your healthcare providers about everything you take—including prescription medications, over-the-counter products, vitamins, and herbal supplements.
5. Can I Drink Alcohol While Taking My Medication?
Alcohol may interact with many medications and increase side effects.
Why can alcohol affect medications?
One of the main organs responsible for metabolizing alcohol is the liver. The liver also plays an important role in breaking down many medications.
Because alcohol and medications often share similar metabolic pathways, drinking alcohol may affect how certain medications are processed. As a result, medication levels in the body may become higher or lower than intended, potentially affecting both safety and effectiveness.
In addition, alcohol itself may increase side effects such as drowsiness, dizziness, impaired coordination, stomach irritation, and liver toxicity.
