A new study raises questions about whether they're truly equivalent to the brand-name versions.

You've no doubt seen them in the grocery store — typically drab-looking packages on the bottom shelf containing lower-priced generic versions of popular brand-name products. Some shoppers look at them with skepticism: Are they really as good? Or does cheaper just mean lower quality?

Many people have the same questions about generic prescription medications, says Dr. Niteesh K. Choudhry, professor of medicine at Harvard Medical School and executive director of the Center for Healthcare Delivery Sciences at Brigham and Women's Hospital. Are generic drugs really the same quality, or is it better to spend more for the name-brand version?

When your doctor prescribes a new medication, you may expect to start feeling the effects right away. But some drugs can take time to make a difference. "It depends on how quickly your body absorbs the medication, how your body distributes it, and how your body breaks down or metabolizes it," says Laura Carr, a pharmacist at Harvard-affiliated Massachusetts General Hospital.

Giving it time

Some medications start working on the first day. These include drugs that treat high blood pressure, like the beta blocker metoprolol (Toprol, Lopressor), which slows down the heart and reduces the force of its contractions; or H2 blockers such as famotidine (Pepcid) and ranitidine (Zantac), which treat heartburn by blocking the stomach's acid-secreting cells from making acid.

Most older adults take some kind of over-the-counter dietary supplement. But are these products right for everyone?

Over-the-counter dietary supplements are big business — more than 90,000 products generate about $30 billion every year in the United States. Older adults make up a big part of these sales, too. A survey of almost 3,500 adults ages 60 and older published Oct. 1, 2017, in The Journal of Nutrition found that 70% use a daily supplement (either a multivitamin or individual vitamin or mineral), 54% take one or two supplements, and 29% take four or more.

But are these pills good medicine, or a waste of money?

Here are the best ways to stop painful cramps — and prevent them from returning.

A muscle cramp always feels like a surprise. The involuntary contraction strikes without warning, whether it's a charley horse in the middle of night or a back spasm as you reach for an everyday object. But don't let that cramp throw you for a loop. "When it suddenly strikes, don't exercise or tighten the muscle. Just gently stretch it to your tolerance. That helps to relax the muscle and relieve the uncontrolled contraction," says Madhuri Kale, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.

What causes cramps?

Exercising without properly warming up the muscles can lead to cramps. Cramps also occur when a muscle is not able to relax properly (such as from a deficiency of magnesium or potassium in your diet) or when it becomes irritated by a buildup of lactic acid (which can happen if you don't rest your muscle after it has exercised a lot). Dehydration can worsen both of these problems. Kale says older adults often don't drink enough water at night because they want to avoid having to go the bathroom, and they end up dehydrated.

Back pain is one of the top reasons that people begin to lose mobility in middle age. Pain can keep people from engaging in physical activity, making it more difficult for them to maintain a healthy weight and keep up their strength, stamina, and balance as they age. So treating and managing back pain that results from injuries or health problems is crucial for staying on the path of a healthy and active life.

Considering that most people spend roughly a third of their lives lying in bed, choosing the right mattress is essential for managing low back pain. It can make the difference in whether you can sleep at night and function the next day.

Of your five senses, which one are you most afraid of losing? If you're like most people, your answer is your ability to see. Because  our eyesight is so precious, it's no wonder that myths abound about your eye health, what can damage our eyes — , and what can protect them. Here, we debunk five common myths — and tell you how to truly keep your eyes healthy.

Myth: Doing eye exercises will delay the need for glasses.
Fact: Eye exercises will not improve or preserve vision, help your eye health, or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.

Q. I have heard a lot about how apple cider vinegar can help improve one's health. Is there anything to this?

A. As with so many dietary fads, apple cider vinegar has seen its share of health claims with little medical evidence to support them. The studies exploring its health benefits have focused on reductions in blood sugar levels and weight loss, but these have been small, short-term trials or animal studies.
