1. Introduction: Stay Healthy and Safe While Trekking in Nepal

Dear Valued Trekking Guests,

Welcome to Nepal! Nepal Voyage Treks is committed to providing you with a safe, enjoyable and memorable trekking experience in the beautiful Himalayas. Whether you are planning to trek to Everest Base Camp, Annapurna Base Camp, the Annapurna Circuit, Manaslu, Langtang, the Nar Phu Valley or other remote mountain destinations, good preparation is essential for your health and safety.

Trekking in Nepal can involve long walking days, steep trails, cold temperatures, remote villages and high elevations. At altitude, the body must adjust to lower oxygen availability. Some trekkers may experience headaches, nausea, dizziness, fatigue, loss of appetite or difficulty sleeping. Other possible problems include dehydration, blisters, muscle injuries, diarrhoea, respiratory infections and cold-related illnesses.

For these reasons, we recommend that every trekker prepares a personal medical kit, informs the company about important medical conditions before departure, obtains suitable travel insurance and follows the instructions of the trekking guide. Our team should also carry an appropriate group first-aid kit and have a clear emergency evacuation plan.

Important: First aid can help manage minor problems and stabilize an injured or ill trekker, but it cannot replace professional medical care. Medicines should be used according to a qualified healthcare professional's advice, and emergency symptoms must never be ignored.

2. First-Aid Medicines and Supplies Nepal Voyage Treks Should Consider Carrying

Nepal Voyage Treks should prepare a well-organized group first-aid kit before every departure. The kit should be adapted to the number of clients, trekking duration, route remoteness, season, maximum altitude and the guide's first-aid training. Medicines must be legally obtained, properly labelled, unexpired and stored according to their instructions.

Pain and fever relief: Paracetamol (acetaminophen) may be included for headaches, muscle aches and fever when appropriate. Ibuprofen may help with certain types of pain and inflammation, but it is not suitable for everyone, particularly people with kidney disease, stomach ulcers, dehydration or certain other medical conditions. The guide should not distribute medicines without checking allergies, contraindications and the manufacturer's instructions.

Allergy relief: An antihistamine such as cetirizine or loratadine may be useful for mild allergic symptoms, including itching, sneezing and some skin reactions. Severe allergic reactions involving breathing difficulty, throat or tongue swelling, collapse or faintness are medical emergencies. An antihistamine is not a substitute for emergency treatment with epinephrine when indicated.

Digestive problems: Oral rehydration salts (ORS) are essential for replacing fluids and electrolytes lost through diarrhoea or vomiting. The kit may also include a thermometer and suitable oral rehydration supplies. Loperamide may sometimes be appropriate for adults with uncomplicated diarrhoea, but it should not be used alone when diarrhoea is accompanied by blood in the stool or high fever. Persistent vomiting, severe abdominal pain, bloody diarrhoea or signs of dehydration require medical assessment. Antibiotics should be used only under appropriate medical guidance.

Cuts, wounds and blisters: Carry sterile gauze pads, adhesive dressings, assorted plasters, blister dressings, medical tape, sterile saline or an appropriate wound-cleaning solution, antiseptic wipes, disposable gloves, small scissors, tweezers and a conforming bandage. Hydrocolloid blister dressings and protective padding can help reduce friction. Wounds should be cleaned promptly, covered with a suitable dressing and monitored for signs of infection.

Sprains and muscle injuries: Include an elastic compression bandage, triangular bandage, medical tape, cold pack and a suitable support bandage. A trekking guide should know how to assess an injury, protect the affected area and arrange assistance when a trekker cannot walk safely. Suspected fractures, severe swelling, deformity, loss of sensation or inability to bear weight require professional assessment.

Respiratory and general medical supplies: A digital thermometer, pulse oximeter, headlamp, emergency blanket, resuscitation face shield, hand sanitiser and a first-aid manual can be useful. A pulse oximeter may help monitor oxygen saturation when interpreted alongside symptoms, altitude and clinical assessment; it cannot independently rule out altitude sickness.

Other useful supplies: Sunscreen, lip balm with SPF, saline eye drops when appropriate, oral hygiene supplies and any additional items required for the group's specific medical needs. A rescue stretcher or other evacuation equipment should be arranged according to the route and the company's emergency plan rather than assumed to be part of every small first-aid kit.

Nepal Voyage Treks should inspect the kit before every departure, replace used or expired items and keep a written inventory. The lead guide should know where the kit is stored and understand how to use its contents safely.

3. Personal Medicines Every Trekking Client Should Bring

We strongly recommend that each client brings their own regular medicines from their home country in sufficient quantities for the entire trip, plus a reasonable extra supply in case of delays. Keep medicines in their original packaging, carry prescriptions where appropriate and pack essential medicines in hand luggage.

Clients who take regular medicines for conditions such as asthma, diabetes, heart disease or other long-term conditions should discuss their trekking plans with their healthcare professional before travelling. They should bring their prescribed medicines, relevant instructions and necessary monitoring supplies. Do not stop or change regular medication without medical advice.

A personal trekking medical kit may include paracetamol or another personally approved pain reliever, oral rehydration salts, blister plasters, adhesive dressings, antiseptic wipes, a digital thermometer, sunscreen, lip balm, hand sanitiser and any personal allergy treatments. Clients who are prone to motion sickness may ask their healthcare professional or pharmacist about a suitable medicine before the journey.

If a client has a history of severe allergies, they should carry their prescribed emergency medication, such as an epinephrine auto-injector, and ensure that their guide knows how to help in an emergency. Clients with asthma should carry their prescribed reliever inhaler and any other required asthma medication.

Clients should not share prescription medicines with other trekkers. Before using any new medicine, they should check the instructions, allergies, possible side effects and interactions with their regular treatments.

4. High-Altitude Sickness: What Every Trekker Must Know

Acute mountain sickness (AMS) can occur when someone ascends to high altitude before their body has adequately acclimatized. It commonly develops after ascent to elevations around 2,500 metres or higher, although individual risk varies. Symptoms can include headache, nausea, dizziness, unusual tiredness and loss of appetite.

The most important prevention measures are a gradual ascent, an appropriate acclimatization schedule and avoiding further ascent when symptoms of altitude sickness develop. Once above approximately 3,000 metres, a commonly recommended approach is to increase sleeping altitude by no more than about 300–500 metres per day, with an additional acclimatization day for every 1,000 metres of sleeping-altitude gain. These are general planning guidelines, not guarantees of safety; the itinerary must be adjusted for the individual and route.

Diamox (acetazolamide) is a medicine that can help prevent acute mountain sickness in appropriate travellers and is sometimes prescribed for treatment. Clients should consult a qualified healthcare professional before the trek to determine whether it is suitable, discuss allergies and other medical conditions, and receive personalized instructions. Nepal Voyage Treks should not prescribe acetazolamide or set a client's dose without appropriate medical authorization.

Dexamethasone is sometimes used by trained medical professionals for selected cases of altitude illness. It is not a substitute for descent and should not be treated as routine self-medication. Its use should follow a clinician's instructions and an established emergency protocol.

Nifedipine may be used by medical professionals in selected cases of high-altitude pulmonary oedema (HAPE), particularly under specific circumstances. It is not a routine medicine for every trekker and must not delay oxygen, descent or emergency evacuation.

No medicine makes it safe to ascend rapidly beyond a person's acclimatization capacity. Nepal Voyage Treks should plan realistic itineraries, monitor clients for symptoms and ensure that guides understand when to stop ascent and arrange descent.

5. Recognizing Dangerous Altitude Illness

High-altitude illness can become life-threatening. The two major emergencies are high-altitude cerebral oedema (HACE), which affects the brain, and high-altitude pulmonary oedema (HAPE), which affects the lungs.

Warning signs of HACE include confusion, unusual behaviour, difficulty walking in a straight line, loss of coordination, extreme drowsiness or reduced consciousness. A severe or worsening headache accompanied by neurological symptoms is especially concerning.

Warning signs of HAPE include breathlessness at rest, a significant decline in exercise ability, worsening cough, chest tightness, rapid breathing or a blue or grey colour around the lips. These symptoms require urgent medical attention.

If severe altitude illness is suspected, stop ascent immediately and arrange urgent descent to a lower altitude, with assistance from trained personnel. Give supplemental oxygen if available and the team is trained to administer it. Use emergency medication only according to the established protocol and qualified medical guidance. Arrange emergency evacuation as necessary.

Do not leave an affected trekker alone, and do not wait for symptoms to improve at the same altitude when HACE or HAPE is suspected. If the person is confused, unconscious or severely breathless, treat the situation as an emergency.

6. Oxygen, Pulse Oximeters and Emergency Equipment in the Mountains

For remote and high-altitude routes, Nepal Voyage Treks should assess the need for portable oxygen, a pulse oximeter, an appropriate emergency communication device and access to evacuation support. These arrangements should depend on the itinerary, altitude, group size, available rescue services and the guide's training.

Supplemental oxygen can be lifesaving in serious altitude illness when administered appropriately, but it must not replace descent or evacuation. A pulse oximeter reading can vary with altitude, cold fingers, movement, circulation and device quality. A normal or relatively reassuring reading does not rule out serious altitude illness when symptoms are present.

On remote routes, mobile phone coverage may be unreliable. A satellite communication device or another reliable emergency communication system should be considered where appropriate. Before departure, the guide should know the emergency contacts, nearest available medical facilities, evacuation options and the procedure for contacting the client's travel insurer.

7. First Aid for Common Trekking Problems

Blisters: Stop when friction or a hot spot begins. Dry the foot, protect the affected area with an appropriate blister dressing and adjust footwear or socks. Do not deliberately remove the skin covering an intact blister. Seek help if there are signs of infection or the trekker cannot walk safely.

Dehydration: Encourage regular fluid intake and use oral rehydration salts when appropriate for fluid loss. Watch for dizziness, unusual weakness, very dark urine, reduced urination or confusion. Severe dehydration requires urgent medical attention.

Cuts and minor wounds: Put on gloves if available, apply direct pressure to bleeding and clean the wound when bleeding is controlled. Cover it with a suitable sterile dressing. Heavy bleeding that does not stop, a deep wound or an embedded object requires urgent medical care.

Sprains and falls: Protect the injured area, avoid unnecessary weight-bearing, and arrange an assessment. Do not force a trekker to continue walking through severe pain. A suspected fracture or serious injury may require immobilization and evacuation.

Hypothermia and cold exposure: Watch for uncontrollable shivering, clumsiness, slurred speech, confusion or unusual sleepiness. Move the person out of the cold and wind, remove wet clothing when feasible, insulate the person and arrange urgent assistance. Handle a severely hypothermic person gently and do not rub their limbs or apply intense direct heat.

Sunburn and snow blindness prevention: Apply broad-spectrum sunscreen with SPF 30 or higher, reapply as directed, use SPF lip protection, wear UV-protective sunglasses and use a hat. Snow glare and ultraviolet exposure can be intense at high altitude.

8. Hygiene, Food Safety and Prevention of Illness

Wash or sanitise hands before eating and after using toilets. Drink properly treated water from a trusted source and avoid untreated water unless it has been made safe using an appropriate method. Eat food that has been properly cooked and stored, and follow your guide's advice about local food and drinking water.

Avoid sharing water bottles, personal medication or hygiene items. Keep minor cuts clean and covered. If a client develops fever, persistent diarrhoea, repeated vomiting or significant respiratory symptoms, inform the guide promptly and seek medical advice when necessary.

Clients should also carry suitable clothing layers, waterproof protection, warm gloves, a hat, sturdy footwear and a sleeping system appropriate for the expected conditions. Proper clothing and pacing help reduce exposure-related problems.

9. Travel Insurance and Emergency Evacuation

Before arriving in Nepal, every trekker should confirm that their travel insurance covers trekking at the maximum planned altitude and includes emergency helicopter evacuation, medical treatment and repatriation where required. Some policies exclude high-altitude trekking or impose specific limits and conditions.

Clients should carry their insurer's emergency telephone number, policy details, passport information and emergency contacts in an accessible and secure format. The trekking guide should know the procedure for requesting assistance and should not assume that a helicopter evacuation will be immediately available in bad weather or remote terrain.

If an emergency occurs, Nepal Voyage Treks will follow the trip's established emergency procedures, communicate with the appropriate rescue or medical services and help coordinate the next steps. Clients should understand that rescue arrangements depend on weather, location, communications, availability and the terms of their insurance policy.

10. Final Health and Safety Checklist

Before starting the trek, please ensure that you have:

• Consulted your healthcare professional about fitness for the planned altitude and itinerary.

• Brought enough regular prescription medication and your personal first-aid supplies.

Acclimatization tips: A checklist for travelers

• Ascend gradually.
• Avoid going directly from low altitude (1,200 m or <4,000 ft) to 2,750 m (>9,000 ft) sleeping altitude in one day.
• Once above 3,000 m (9,850 ft), move sleeping altitude by no more than 500 m (1,600 ft) per day and plan an extra day of acclimatization for every additional 1,000 m (3,300 ft) of sleeping altitude gain.
• Consider using acetazolamide to speed acclimatization if abrupt ascent is unavoidable.
• Avoid alcohol for the first 48 hours at high altitude.
• If a regular caffeine user, continue using to avoid a withdrawal headache that could be confused with an altitude headache.
• Participate in only mild exercise for the first 48 hours at altitude.
• A high-altitude exposure (>2,750 m; >9,000 ft) for ≥2 nights, within 14 days before the trip, is useful but closer to the trip departure is better.
