Most legal medical marijuana -- more than 90% -- is stronger than what doctors recommend for chronic pain relief, a new study finds.

"We know that high-potency products should not have a place in the medical realm because of the high risk of developing cannabis-use disorders, which are related to exposure to high THC-content products," said lead author Dr. Alfonso Edgar Romero-Sa...

Asthma and allergy drug montelukast -- sold as a generic and under the brand name Singulair -- will get a "boxed warning" over potential ties to neuropsychiatric effects, the U.S. Food and Drug Administration announced on Wednesday.

The drug has long carried a warning that it has been linked with an increased risk of "agitation, depression, sleeping problems, and suicidal thoughts and...

People who use marijuana either medicinally or recreationally should remember that pot can have potentially harmful interactions with medications they take regularly, a new report warns.

This is particularly true of older folks, who often are on many different drugs to manage a variety of chronic ailments, said lead researcher Tony Antoniou. He's an associate professor in the departme...

Many Americans battling autoimmune illnesses such as rheumatoid arthritis or psoriasis turn to a long-used drug, methotrexate, for relief.

But until now there's been little comprehensive research on side effects tied to the drug.

A new study funded by the U.S. National Institutes of Health may fill that gap. It finds that patients who take methotrexate do have a slight-to-mo...

Patients taking a common diuretic to help lower blood pressure may be better off with a similarly effective but safer one, a new study suggests.

Current guidelines recommend the drug chlorthalidone (Thalitone) as the first-line diuretic. But it can have serious side effects that can be avoided with another diuretic, hydrochlorothiazide (Hydrodiuril), researchers say.

"Diur...

Viagra can salvage a man's sex life, but in rare cases it may temporarily steal his sight.

The case report details 17 Turkish males who wound up in the hospital after taking sil...

Dry mouth can be a troubling side effect of radiation therapy, but acupuncture may ease its symptoms, a new study suggests.

Of 339 patients getting radiation for head and neck cancer in the United States and China, those who had acupuncture had fewer symptoms of dry mouth (xerostomia) than those who didn't have acupuncture.

Patients who had fake acupuncture (placebo) had a...

Many older Americans take a variety of prescription drugs, yet new research suggests that combining various medications is not always wise.

Taking lots of different drugs for different conditions is called "polypharmacy," and a team of researchers set out to find how doctors take this into account in their prescribing. To address this, providers discuss "deprescribing" -- working with...

A commonly prescribed muscle relaxant known as baclofen can leave older kidney patients so disoriented that they land in the hospital, a new study warns.

The widely used bladder drug Elmiron may cause eye damage, a new study claims.

A report released last year suggested that the drug -- known as pentosan polysulfate sodium and used by hundreds of thousands of people for decades -- may be toxic to the retina, the light-sensing tissue at the back of the eye.

That led researchers to examine a database of 4.3 million patients at ...

Ten years after radiation treatment for head and neck cancer, some patients may develop problems speaking and swallowing, a new study finds.

These problems are related to radiation damage to the cranial nerves, the researchers explained. The condition is called radiation-induced cranial neuropathy.

"We had always thought that radiation did not damage cranial nerves because t...

In the largest investigation of its kind, researchers conclude that subjecting prostate cancer patients to radiation therapy immediately after surgery doesn't give them an advantage in staying cancer-free.

The finding stems from a review of four studies that together tracked outcomes for more than 3,500 prostate cancer patients from multiple countries.

If the findings help c...

More Americans use marijuana to help them cope with an illness than just to get high, a new study finds.

Nearly 46% of those who use pot say they do so because of a medical condition, compared with 22% who say they use marijuana for recreation.

Serious falls aren't the sole domain of seniors: New research shows they are a significant risk among middle-aged adults.

Men may soon have help making that decision.

Researchers from the United Kingdom report that they've created a urine test that can predict the aggressiveness of a pr...

Treating men with low-risk prostate cancer with just one high dose of radiation may be safe and effective, British researchers report.

Therapy for prostate cancer typically involves low-dose radiation given over several days or weeks. Conversely, high-dose radiation is given once through a set of tiny tubes inserted directly into the tumor.

"For low-risk patients, a single ...

One out of every three U.S. cancer patients uses alternative or complementary therapies, but many keep that info from their doctors, a new study finds.

For years, doctors have debated the safety of the acne drug most commonly known as Accutane, but new research suggests the medication does not boost depression risk among its users.

As many as 7 out of 10 people with type 2 diabetes can achieve long-term disease remission by having weight-loss surgery called gastric bypass, according to a new Danish study.

The surgery isn't necessarily a cure for type 2 diabetes. Some people who go into remission and appear to no longer have the disease can relapse and start having symptoms again. In this study, 27 percent of peop...

People who take prescription opioid painkillers are at increased risk for pneumonia, especially those with HIV, a new study suggests.

The findings support concerns that prescription opioids can weaken the immune system. Doctors who prescribe opioids need to reduce patients' risk of pneumonia through vaccination and by encouraging them to stop smoking, the researchers said.

F...

If you have type 2 diabetes and you're taking canagliflozin to help control your blood sugar, a new study has some good news for you: The drug doesn't appear to raise the risk of bone fractures.

And the modest pain relief sometimes came...

Tamoxifen is considered a vital weapon in the fight against breast cancer, but many women who have to take the drug struggle with its significant side effects.

On top of that, the lower dose -- ...

A marijuana-derived drug that helps control epileptic seizures appears to become less effective over time in some patients, a new Israeli study reports.

School is in full swing, and with it comes a plethora of colds passed back and forth among kids.

But parents who want to alleviate a sick child's misery would do best to avoid over-the-counter cough and cold remedies.

The fat accumulation -- called paradoxical adipose hyperplasia -- then needs invasive liposuction to ...

Doctors and pain specialists have been turning to anticonvulsive drugs for treatment of lower back pain more often over the past decade.

A newer type of cancer treatment may offer the chance of longer survival, but the drugs could also trigger new side effects, such as vision problems.

Testing for small changes in the flow of lymph fluids after breast cancer surgery can spot the start of a painful swelling known as lymphedema before it becomes hard to treat, a new study suggests.

Many breast cancer patients say they've heard scary stories about radiation therapy, but their actual experience is usually better, new research finds.

The study of more than 300 women who underwent breast radiation found that almost half had heard "frightening" stories going into treatment. But only 2 percent ultimately agreed that the stories were true.
