Metformin: how it works, side effects and tips for taking it

By the Medsmingle Team · Updated 13 November 2026

This is a prescription medicine. Only take it if it has been prescribed for you, and follow your doctor’s and pharmacist’s instructions.

Metformin is a commonly prescribed medicine for type 2 diabetes. Treatment choice depends on individual health needs; metformin has been used for decades and doesn’t usually cause low blood sugar or weight gain on its own.

How it works

Metformin lowers the amount of sugar your liver releases into the blood and helps your body respond better to insulin.

Common side effects

  • Nausea, upset stomach, diarrhea or gas, mostly in the first few weeks
  • A metallic taste
  • Reduced appetite

Tips to reduce stomach side effects

  • Take it with meals
  • Your doctor will usually start with a low dose and increase it slowly
  • Ask about the extended-release (XR) form, which is often easier on the stomach

Vitamin B12

Long-term use can lower vitamin B12 levels. Ask your doctor about a B12 test, especially if you have tingling, numbness or tiredness.

Lactic acidosis: rare but serious

Very rarely, metformin can cause a build-up of lactic acid, mainly in people with serious kidney, liver or heart problems or heavy alcohol use. Get urgent help for unusual muscle pain, trouble breathing, severe tiredness, stomach pain with vomiting, or feeling cold and dizzy.

Important to know

  • Your doctor will check your kidney function regularly
  • Metformin may need to be paused for some contrast scans, procedures or acute illnesses. Ask your clinician what to do if you develop severe vomiting, diarrhea or dehydration; do not make routine changes on your own.
  • Avoid heavy drinking
  • Tell your doctor about all other medicines

Frequently asked questions

Does metformin cause weight loss?

Some people lose a small amount of weight, but it isn’t a weight-loss medicine.

Can I stop metformin if my sugar is normal?

Don’t stop without talking to your doctor; normal readings may be because the medicine is working.

How to prevent UTIs: habits that help and what the evidence says

By the Medsmingle Team · Updated 13 November 2026

Urinary tract infections (UTIs) are very common, especially in women: about half of women will have at least one. If you get them often, a few habits can lower your risk, but a UTI itself usually needs antibiotics from a doctor.

Symptoms of a UTI

  • Burning or pain when you pee
  • Needing to pee often or urgently, passing only small amounts
  • Cloudy, bloody or strong-smelling urine
  • Pain or pressure in the lower belly

Habits that help prevent UTIs

  • Drink enough water. Adequate fluids may help. Ask for an individual fluid target if you have heart or kidney disease or a fluid restriction.
  • Pee after sex if convenient, but this does not guarantee prevention.
  • Wipe front to back after using the toilet.
  • Don’t hold it in for long periods.
  • Avoid irritating products such as douches, scented sprays and spermicides.
  • After menopause, ask your doctor about vaginal estrogen, which can reduce repeat UTIs.

Do supplements help?

  • Cranberry products: may modestly reduce repeat UTIs in some women; they don’t treat an active infection.
  • D-mannose: early studies were promising, but a large 2024 trial found no benefit over placebo.
  • Herbal products: do not rely on them to prevent or treat an infection.

See a doctor if you have UTI symptoms

A clinician assesses symptoms and may use urine tests; treatment depends on your circumstances. Get urgent care if you have fever, chills, back or side pain, nausea or vomiting, or blood in your urine, as these can be signs of a kidney infection. Also see a doctor promptly if you’re pregnant, male, or a child has UTI symptoms.

If you have 2 or more UTIs in 6 months, ask your doctor about further tests and prevention options.

Frequently asked questions

Can a UTI go away on its own?

Mild UTIs sometimes clear without antibiotics, but untreated infections can spread to the kidneys. It’s safest to see a doctor.

Does cranberry juice cure a UTI?

No. It may help prevent repeat infections for some women but won’t treat an infection that has started.

Why do I keep getting UTIs?

Common reasons include sex, some contraceptives, menopause and not drinking enough. A doctor can check for other causes.

Sore muscles after a workout: what helps and how long it lasts

By the Medsmingle Team · Updated 13 November 2026

Muscle soreness that starts 12 to 24 hours after exercise and peaks around 1 to 3 days later is called delayed onset muscle soreness (DOMS). It’s common after a new or harder workout and is a normal part of your muscles adapting. It usually fades within 5 days.

What helps

  • Keep moving gently: walking, cycling or swimming at an easy pace eases stiffness better than complete rest.
  • Warmth: a warm bath or heat pack relaxes tight muscles.
  • Massage or foam rolling: can reduce soreness and help you feel better.
  • Sleep and protein: muscles repair overnight; include protein at meals.
  • Stay hydrated.

Rubs, balms and gels

  • Menthol or camphor balms, create a cooling or warming feeling that can distract from aches.
  • Diclofenac gel (Voltaren) is an anti-inflammatory pain reliever used for certain types of joint pain. It is not a routine recovery aid after a workout; check its approved uses and warnings with a pharmacist.

Apply to unbroken skin only, wash your hands afterwards, and don’t use with a heating pad, which can cause burns.

Pain relievers

Acetaminophen or ibuprofen can ease soreness for a day or two. Use the lowest dose that works and follow the label. Avoid ibuprofen if you have stomach ulcers, kidney disease or take blood thinners.

Prevention

  • Increase intensity, weight or distance gradually, according to your fitness and recovery
  • Warm up for 5 to 10 minutes first
  • Repeat the same activity regularly; soreness lessens as your body adapts

Soreness or injury?

Typical soreness is a dull ache in muscles you have exercised. Its pattern alone cannot rule out an injury. See a doctor if you have:

  • Sharp or sudden pain during exercise, a pop, or swelling and bruising
  • Pain that’s still severe after 5 to 7 days
  • Very dark (tea- or cola-colored) urine, extreme muscle pain or weakness after an intense workout: get urgent care, as this can be rhabdomyolysis, which can damage the kidneys

Frequently asked questions

Should I exercise with sore muscles?

Light activity is fine and often helps. Give the sore muscle group a break from hard training for a day or two.

Is soreness a sign of a good workout?

Not necessarily. It mainly means you did something new or harder. You can build fitness without being sore.

Do ice baths help?

They may reduce soreness slightly, but warm baths and gentle movement feel better for many people.

Giloy (guduchi): benefits, evidence and the liver safety warning

By the Medsmingle Team · Updated 13 November 2026

Giloy, also called guduchi or Tinospora cordifolia, is a climbing plant that Ayurveda calls “amrita”, the root of immortality. It became especially popular as an immunity herb during the COVID-19 pandemic. It has interesting early research, but also a safety signal that’s important to know about.

Traditional uses

  • Supporting immunity and recovery from fever
  • Digestion
  • Blood sugar balance
  • Joint comfort

What the evidence shows

  • Immunity: lab and animal studies show effects on immune cells, but good-quality human trials are lacking.
  • Blood sugar: some small studies suggest it may lower blood sugar, which matters if you take diabetes medicine.
  • Fever and infections: no reliable evidence that it treats or prevents infections like dengue or COVID-19.

The liver warning

Since 2020, doctors in India have reported cases of liver injury, including autoimmune-like hepatitis, in people taking giloy, often for several weeks or months. Many had an underlying autoimmune tendency or took other supplements too. Most recovered after stopping, but some cases were serious. LiverTox documents multiple reports, including severe injury.

Stop taking giloy and see a doctor if you notice yellow skin or eyes, dark urine, pale stools, itching or unusual tiredness.

Who should avoid it or check with a doctor first

  • People with liver disease or an autoimmune condition (such as rheumatoid arthritis, lupus or type 1 diabetes)
  • Anyone taking diabetes medicine, immunosuppressants or other herbal supplements
  • Pregnant or breastfeeding women and children
  • People having surgery in the next 2 weeks (because of blood sugar effects)

Before considering giloy

No brand or label dose guarantees safety. Discuss the liver-injury reports with a qualified healthcare professional before using it. Do not use it to prevent or treat infections or to replace prescribed medicines.

Frequently asked questions

Is giloy safe to take daily?

Safety cannot be assumed from the label or a short course. Liver injury has been reported, including serious cases. Discuss alternatives with your clinician.

Does giloy boost immunity?

It’s traditionally used for immunity, but there’s not yet good evidence in people that it prevents infections.

Can people with diabetes take giloy?

Only with a doctor’s advice, because it may lower blood sugar further when combined with diabetes medicine.

Gokshura (Tribulus terrestris): benefits, evidence and side effects

By the Medsmingle Team · Updated 13 November 2026

Gokshura, known in the West as Tribulus terrestris or puncture vine, is a plant used in Ayurveda for men’s vitality and urinary health. It’s also sold in sports supplements with claims about testosterone. Here’s what the evidence says.

Traditional uses

  • Men’s vitality and libido
  • Urinary and kidney health
  • General strength and energy

What studies show

  • Testosterone and muscle: most human studies found no meaningful increase in testosterone or muscle strength in healthy men.
  • Libido: a few small trials suggest it may improve sexual desire in some men and women, but the studies are small and short.
  • Urinary health: evidence in people is very limited.

Small studies do not establish a dependable treatment benefit. Gokshura should not replace assessment or prescribed treatment for persistent sexual or urinary symptoms.

How it’s taken

Gokshura is available as tablets such as Himalaya Gokshura. Preparations and concentrations differ. There is no established dose proven to treat ED or raise testosterone; ask a clinician before using a supplement.

Side effects

  • Upset stomach, nausea or cramps are the most common
  • Rare reports of kidney and liver problems with high doses or long-term use
  • Possible lowering of blood sugar and blood pressure

Who should avoid it or check with a doctor first

  • Pregnant or breastfeeding women
  • People with kidney or liver disease, or a history of kidney stones
  • Anyone taking diabetes, blood pressure, heart (such as digoxin) or lithium medicines
  • People with hormone-sensitive conditions, including prostate cancer
  • Competitive athletes: check supplements for banned substances

See a doctor if

You have low energy, low libido or erection problems that last. These can be signs of conditions such as diabetes, heart disease, low testosterone or depression, which need proper diagnosis.

Frequently asked questions

Does gokshura increase testosterone?

Most human studies say no, at least not in healthy men.

How long does gokshura take to work?

Studies on libido usually lasted 4 to 12 weeks. These trials do not establish a reliable time to benefit or prove long-term safety.

Can women take gokshura?

Some small studies included women, but it isn’t advised during pregnancy or breastfeeding. Check with a doctor first.
