Minoxidil, best known under the brand name Rogaine, is one of the few hair-loss treatments you can buy without a prescription. It comes in two main strengths, 2% and 5%. Choosing the right one depends mostly on who you are and how you’ll use it.

The short answer

• Rogaine 5% is designed for men with hereditary hair loss at the crown (top) of the head.
• Rogaine 2% is the strength approved for women, and men can use it too.

How minoxidil works

Minoxidil is thought to widen blood vessels around the hair follicles and lengthen the hair’s growth phase. Over time, shrunken follicles can produce thicker, longer hairs. It works best for hereditary thinning (male- or female-pattern hair loss), not for sudden, patchy or unexplained hair loss.

2% vs 5% compared

• Strength: 5% contains more than twice the minoxidil. In studies in men, 5% regrew more hair, and faster, than 2%.
• Who it’s for: 5% solution is labelled for men. Women should use 2% solution (or a 5% foam labelled for women) unless a doctor advises otherwise, because higher strengths are more likely to cause unwanted facial hair.
• Side effects: both can cause scalp itching, dryness or flaking. These are a little more common with 5%.
• How to use: both solutions are applied as 1 mL twice a day to a dry scalp.

How long until you see results?

Be patient. Most people need 2 to 4 months of twice-daily use to notice a difference, and full results can take up to a year. Many people see extra shedding in the first few weeks. That’s normal, and usually a sign that older hairs are making way for new growth. If you see no improvement after 4 months, stop and talk to a doctor.

Minoxidil only works while you use it. If you stop, the regrown hair usually falls out within a few months.

Tips for the best results

• Apply to a dry scalp, directly onto the thinning area, not just the hair.
• Use it every day, twice a day. Missing doses slows results.
• Let it dry fully before styling or going to bed.
• Don’t use more than 1 mL per dose. More product won’t work faster.
• Wash your hands after applying.

Who shouldn’t use minoxidil

• Anyone under 18
• People whose hair loss is sudden, patchy, or linked to childbirth, illness or medication
• Anyone with a red, irritated, infected or sunburned scalp
• People with heart disease should ask a doctor first
• Pregnant or breastfeeding women

Stop using it and see a doctor if you get chest pain, a fast heartbeat, dizziness, or sudden weight gain or swelling of your hands or feet.

Pet warning: minoxidil is very toxic to cats. Keep the bottle out of reach, and don’t let pets lick treated skin or hair.

Motion sickness happens when your eyes, inner ear and body send your brain conflicting signals about movement. Reading in a car, for example, tells your eyes you’re still while your inner ear feels every bump. The result can be nausea, dizziness, cold sweats and vomiting. It’s common in cars, boats, planes, trains and even VR headsets, and children aged 2 to 12 are especially prone to it.

Prevention tips that work

• Pick the steadiest seat. Front seat in a car, over the wing on a plane, the middle of a boat near the waterline, or a forward-facing seat on a train.
• Look at the horizon. Fixing your eyes on a stable, distant point helps your eyes and inner ear agree.
• Avoid screens and reading while moving.
• Get fresh air. Open a window or point an air vent at your face.
• Eat light. Have a small, bland meal before travelling. Avoid heavy, greasy or spicy food and alcohol.
• Stay hydrated with small sips of water.
• Take breaks on long car journeys.

Medicines for motion sickness

Over-the-counter antihistamines like dimenhydrinate (Dramamine) are the most common treatment. They work best when taken before symptoms start:

• Take the first dose 30 to 60 minutes before you set off.
• Adults and children 12+: 1 to 2 tablets (50 to 100 mg) every 4 to 6 hours, no more than 8 tablets in 24 hours.
• Children 6 to 11: ½ to 1 tablet every 6 to 8 hours, no more than 3 tablets in 24 hours.

Dramamine causes drowsiness. Don’t take it if you’re the one driving, and avoid alcohol while using it. Ask a doctor first if you have glaucoma, breathing problems, or trouble urinating due to an enlarged prostate.

If you already feel sick

• Stop reading or using your phone, and close your eyes or look at the horizon.
• Recline your seat and keep your head still.
• Sip cold water or nibble a plain cracker.
• If possible, stop and get out for a few minutes of fresh air.

When to see a doctor

See a doctor if you have dizziness or vertigo when you’re not travelling, symptoms that continue for long after the journey ends, or if you’re pregnant and need motion sickness treatment.

Athlete’s foot (tinea pedis) is a fungal skin infection that usually starts between the toes. It’s very common, it spreads easily in warm, damp places like changing rooms and pool areas, and you don’t have to be an athlete to get it. The good news: it usually clears up with an over-the-counter antifungal cream.

Symptoms

• Itching, stinging or burning between the toes or on the soles
• Red, scaly, peeling or cracked skin
• Skin that looks white and soggy between the toes
• Small blisters, in some cases

How to treat it

Antifungal creams kill the fungus causing the infection. Butenafine (the ingredient in Mentax) is one of the fastest-acting options:

• Between the toes: apply twice a day for 1 week, or once a day for 4 weeks.
• Bottom or sides of the foot: apply twice a day for 4 weeks.

Wash and dry your feet thoroughly before each application. Keep using the cream for the full course, even if your skin looks better sooner, or the infection is likely to come back.

How to stop it coming back

• Dry your feet carefully after washing, especially between the toes.
• Wear breathable cotton or moisture-wicking socks and change them every day.
• Alternate shoes so each pair dries out fully between wears.
• Wear sandals or flip-flops in shared showers, gyms and pool areas.
• Don’t share towels, socks or shoes.
• Wash socks and towels at 60°C (140°F) to kill the fungus.

Related fungal infections

The same fungus can cause jock itch (in the groin) and ringworm (a red, ring-shaped rash on the body). Butenafine cream treats both, applied once a day for 2 weeks. To avoid spreading athlete’s foot to the groin, put your socks on before your underwear.

When to see a doctor

• No improvement after 2 weeks of treatment, or it’s not gone after the full course
• The infection has spread to your toenails (thick, yellow or crumbly nails need different treatment)
• The skin is very red, swollen, hot, painful or leaking pus, which may be a bacterial infection
• You have diabetes or a weakened immune system. Foot infections need extra care.

When hay fever or hives strike, most people reach for one of three over-the-counter antihistamines: Zyrtec, Claritin or Allegra. All three are “second-generation” antihistamines, which means they cause much less drowsiness than older ones like Benadryl, and one dose lasts 24 hours. But they aren’t identical. Here’s how they compare.

The quick comparison

• Zyrtec (cetirizine 10 mg): often works fastest, usually within an hour. It’s the most likely of the three to cause drowsiness, though most people feel fine.
• Claritin (loratadine 10 mg): the least likely to cause drowsiness. It may take a little longer to kick in, typically 1 to 3 hours.
• Allegra (fexofenadine 180 mg): also very unlikely to cause drowsiness, and works within about an hour. Take it with water only. Fruit juices like grapefruit, orange and apple can stop it being absorbed properly.

What they all treat

All three relieve the same symptoms of hay fever and other upper respiratory allergies:

• Sneezing
• Runny nose
• Itchy, watery eyes
• Itchy nose or throat

All three also relieve itching from hives.

Which one should you choose?

• You need to stay sharp (driving, studying, operating machinery): Claritin or Allegra are the safest bets for avoiding drowsiness.
• You want the fastest relief: Zyrtec or Allegra.
• One didn’t work well for you: it’s worth trying another. People respond differently, and switching often helps.
• You drink a lot of fruit juice in the morning: Zyrtec or Claritin may be easier than Allegra.

Tips for getting the most out of allergy tablets

• Take it before symptoms peak. If you know pollen season is coming, start a daily tablet a few days before. Antihistamines work best at preventing symptoms.
• Take one at the same time each day during allergy season.
• Don’t double up. Never take two of these antihistamines together, or more than one dose in 24 hours.
• Cut your exposure. Keep windows closed on high-pollen days, shower and change clothes after being outdoors, and wash bedding weekly in hot water.

When to see a doctor

• Your symptoms don’t improve after a few days of treatment
• You have wheezing, shortness of breath or chest tightness, which may be asthma
• You have liver or kidney disease, or you’re pregnant or breastfeeding
• You’re 65 or older (for Zyrtec), or buying for a child under 6

Get emergency help if hives come with swelling of the lips, tongue or throat, trouble breathing, or dizziness.

Ozempic and Mounjaro are two of the most talked-about medicines of recent years. Both are once-weekly injections first approved to treat type 2 diabetes, and both can also lead to weight loss. They are not the same medicine, though, and neither is right for everyone. This guide explains how they work, how they differ, their side effects, and how to use them safely.

What is Ozempic?

Ozempic is the brand name for semaglutide, made by Novo Nordisk. It belongs to a group of medicines called GLP-1 receptor agonists. GLP-1 is a hormone your gut releases after you eat. Semaglutide copies its effects: it helps your pancreas release insulin when blood sugar is high, lowers the amount of sugar your liver releases, slows how fast your stomach empties, and reduces appetite.

Ozempic is approved in the US for adults with type 2 diabetes to improve blood sugar control, and to lower the risk of heart attack and stroke in adults with type 2 diabetes and heart disease. A higher-dose version of semaglutide is sold under a different brand name (Wegovy) specifically for weight management.

What is Mounjaro?

Mounjaro is the brand name for tirzepatide, made by Eli Lilly. It works on two hormone receptors instead of one: GLP-1 and GIP. This “dual” action is the main difference between the two medicines. Mounjaro is approved for adults with type 2 diabetes. Tirzepatide for weight management is sold under a different brand name (Zepbound).

Ozempic vs Mounjaro at a glance

• Active ingredient: Ozempic contains semaglutide. Mounjaro contains tirzepatide.
• How it works: Ozempic acts on GLP-1 receptors. Mounjaro acts on both GIP and GLP-1 receptors.
• How it’s taken: Both are injected under the skin once a week, in the stomach, thigh or upper arm.
• Dosing: Both start at a low dose that is raised step by step over several weeks. This helps the body get used to the medicine and reduces stomach side effects.
• Weight loss: In head-to-head research, tirzepatide has generally led to more weight loss than semaglutide, but results vary a lot from person to person.

Common side effects

Most side effects of both medicines affect the stomach and gut, and they are most common when starting or increasing the dose:

• Nausea and vomiting
• Diarrhoea or constipation
• Stomach pain, bloating or indigestion
• Reduced appetite
• Tiredness

Eating smaller meals, stopping when you feel full, avoiding greasy food and drinking enough fluids can help. Vomiting and diarrhoea can cause dehydration, which in turn can harm the kidneys, so tell your doctor if these don’t settle.

Serious side effects to know about

• Thyroid tumours: Both medicines carry a boxed warning because they caused thyroid C-cell tumours in rodents. It isn’t known whether this happens in people. They should not be used by anyone with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). See a doctor if you notice a lump in your neck, trouble swallowing, or a hoarse voice that doesn’t go away.
• Pancreatitis: Severe stomach pain that may spread to the back, with or without vomiting, needs urgent medical attention.
• Gallbladder problems: Including gallstones, especially with rapid weight loss.
• Low blood sugar: The risk is higher if you also take insulin or a sulfonylurea (such as glipizide or glimepiride).
• Eye changes: People with diabetic retinopathy should have their eyes monitored.
• Serious allergic reactions: Swelling of the face, lips or throat, or trouble breathing, needs emergency care.

Who should not use them?

• People with a personal or family history of MTC or MEN 2
• Anyone who has had a serious allergic reaction to semaglutide or tirzepatide
• People who are pregnant or planning a pregnancy, unless a doctor advises otherwise. Weight loss is not recommended during pregnancy.
• People with type 1 diabetes. These medicines are not a substitute for insulin.

If you have a history of pancreatitis, kidney problems, gallbladder disease, severe stomach problems (such as gastroparesis) or diabetic eye disease, your doctor needs to know before you start.

Important medicine interactions

Because both medicines slow stomach emptying, they can change how other tablets are absorbed. Mounjaro can make birth control pills less effective. Women taking the pill are usually advised to use a non-oral or backup method for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase. Always give your doctor and pharmacist a full list of what you take.

Beware of fake Ozempic and Mounjaro

High demand has led to a large number of counterfeit and unapproved versions being sold online. Fake pens may contain the wrong dose, the wrong ingredient, or be contaminated, and people have needed hospital treatment after using them. Regulators, including the US FDA, have warned the public about counterfeit semaglutide and tirzepatide.

To protect yourself:

• Only use these medicines with a valid prescription from a licensed doctor.
• Get them from a licensed pharmacy that asks for your prescription. A seller that doesn’t ask for one is a warning sign.
• Check the packaging, label, lot number and expiry date, and compare them with the manufacturer’s information.
• Be cautious of prices that seem far too low, and of products described as “generic” Ozempic or Mounjaro.

Are they right for you?

Ozempic and Mounjaro can be very effective for the right person, but they are prescription medicines that need proper medical supervision. A doctor can check whether one of them suits you, choose the right dose, monitor your progress, and watch for side effects. They work best alongside healthy eating and regular physical activity.

Key takeaways

• Ozempic (semaglutide) works on one hormone receptor. Mounjaro (tirzepatide) works on two.
• Both are weekly injections approved for type 2 diabetes. Related brands of the same ingredients are approved for weight management.
• Stomach side effects are common, especially at the start. Serious side effects are rare but important to know.
• Only use them with a prescription, from a licensed pharmacy.
