Medications: practical guides on drugs, doses and side effects

You want straight answers about medicines — what works, what doesn't, and what to watch for. This page collects clear, practical articles on common drug questions: how to switch inhalers, safe alternatives when a drug stops working, and tips to protect your heart. No jargon, just usable info you can take to your doctor or pharmacist.

If you're switching inhalers, start with our Symbicort to Advair guide. It explains how doctors convert doses, what side effects might change, and how to handle prior authorization with insurers. Tip: don’t stop one inhaler and start another on your own. Talk to your prescriber about dose equivalence and keep rescue inhalers handy during the switch.

Looking for alternatives because a medicine isn't helping? Our piece on Verapamil alternatives breaks down seven options used in 2025 for conditions like high blood pressure, arrhythmias, and cluster headaches. It lists who might benefit from each substitute and which side effects to expect, so you can ask targeted questions during your visit.

For viral infections, the Valtrex alternatives article shows other antiviral choices and when doctors might pick them. If Valtrex causes side effects or interaction worries, there are proven options that may fit your health needs. The article highlights how some meds are better for frequent outbreaks, while others suit single episodes.

What to check before changing meds

Always check interactions with other drugs you take, recent lab results, and existing conditions like kidney or liver disease. Some drugs need dose changes based on kidney function; others require periodic blood tests. Bring a current medication list to appointments — it speeds up safe, practical decisions.

Insurance and cost matter. Our pages show realistic steps for getting prior authorization and alternatives that can be cheaper or covered more easily. Ask your clinic about samples, generic options, and patient assistance programs if cost is a barrier.

How to use these articles

Start with the topic that matches your problem, read the practical tips, then make a list of questions for your clinician. Use the dosing and side-effect notes to spot red flags that need prompt medical attention. If an article suggests monitoring (like liver tests with fenofibrate), book the labs and mark follow-up dates on your calendar.

We update guides as new evidence appears, so check back if your situation changes. If you want help finding the right article quickly, use the search bar or filter by condition. And remember: these guides help you talk with your healthcare team — they don’t replace professional advice tailored to your history.

The Connection Between Cholesterol Levels and Stroke Risk

In my recent research, I've come to understand there's a significant link between cholesterol levels and stroke risk. High levels of LDL or 'bad' cholesterol can lead to a build-up in the arteries, reducing blood flow to the brain and potentially causing a stroke. On the contrary, HDL or 'good' cholesterol can help remove LDL from the bloodstream, reducing the risk. Therefore, maintaining a healthy balance of cholesterol is key in stroke prevention. I believe it's crucial to keep an eye on our cholesterol levels and make necessary lifestyle changes if needed.
