Household Medication & Medical Information Guide

A practical reference guide covering common over-the-counter medications, first aid supplies, medication list templates, storage guidelines, and safety information for Lake Havasu City households and seasonal residents.

Educational Reference Only: This guide is for general informational and educational purposes. It is not a substitute for professional medical advice, diagnosis, or treatment. Always read medication labels completely and consult your physician or pharmacist before starting, stopping, or changing any medication. In a medical emergency, call 911 immediately.

About This Guide

This guide is designed to help Lake Havasu City residents and seasonal visitors maintain a well-stocked, organized household medicine cabinet and first aid kit. It covers the most commonly used over-the-counter medications, their uses, and important safety notes.

This is a reference resource — not a prescription guide. Always consult your physician or pharmacist for personalized medication advice, especially if you take prescription medications or have chronic health conditions.

Your Personal Medication List

Every adult should maintain a current, written medication list. This is one of the most important things you can do for your healthcare safety — especially when traveling, visiting a new provider, or in an emergency situation. Your medication list should include the following information for each medication:

  • Medication name (brand and generic)
  • Dosage (e.g., 10 mg, 500 mg)
  • How often you take it (e.g., once daily, twice daily, as needed)
  • What it is prescribed for (e.g., blood pressure, diabetes, pain)
  • Prescribing physician name and phone number
  • Pharmacy name and phone number
  • Date prescription was last filled
  • Any known allergies or adverse reactions

Tip: Keep a printed copy in your wallet, a photo on your phone, and a copy posted on your refrigerator (emergency responders are trained to check there). Share a copy with your emergency contact person.

Pain Relief & Fever Reducers

These are among the most commonly used over-the-counter medications. Having both acetaminophen and an NSAID on hand covers most common pain and fever situations.

Acetaminophen (Tylenol)

Generic: Acetaminophen

Use: Pain relief, fever reduction

Do not exceed 3,000–4,000 mg/day. Avoid if you drink alcohol regularly or have liver conditions. Safe for most adults including those who cannot take NSAIDs.

Ibuprofen (Advil, Motrin)

Generic: Ibuprofen

Use: Pain, fever, inflammation

Take with food. Avoid if you have kidney disease, stomach ulcers, or are on blood thinners. Not recommended for those over 65 without physician guidance.

Naproxen Sodium (Aleve)

Generic: Naproxen sodium

Use: Longer-lasting pain and inflammation relief

Longer-acting than ibuprofen. Same cautions as ibuprofen. One tablet typically lasts 8–12 hours.

Aspirin (Bayer, generic)

Generic: Aspirin

Use: Pain, fever, anti-inflammatory; low-dose for heart health

Many adults take low-dose (81 mg) aspirin daily for cardiovascular health — only do so under physician guidance. Do not give to children or teenagers.

Allergy, Cold & Sinus

Arizona's desert environment, dust, and seasonal plant blooms can trigger allergies even in people who have never had them before. These medications address common allergy and cold symptoms.

Loratadine (Claritin)

Generic: Loratadine

Use: Non-drowsy allergy relief — sneezing, runny nose, itchy eyes

Non-sedating. Safe for most adults. Once daily dosing. Good choice for daytime allergy management.

Cetirizine (Zyrtec)

Generic: Cetirizine

Use: Allergy relief — may cause mild drowsiness in some people

Slightly more effective than loratadine for some people. May cause mild drowsiness. Once daily.

Diphenhydramine (Benadryl)

Generic: Diphenhydramine

Use: Allergy relief, sleep aid, mild sedation

Causes significant drowsiness. Not recommended for older adults as a regular sleep aid — associated with increased fall risk and cognitive effects. Use with caution.

Pseudoephedrine (Sudafed)

Generic: Pseudoephedrine

Use: Nasal and sinus congestion

Kept behind the pharmacy counter — requires ID to purchase. Avoid if you have high blood pressure, heart disease, or take MAOIs.

Phenylephrine (Sudafed PE)

Generic: Phenylephrine

Use: Nasal congestion (less effective than pseudoephedrine)

Available on shelves without ID. Less effective than pseudoephedrine for most people. Same cardiovascular cautions apply.

Saline Nasal Spray

Generic: Sodium chloride nasal spray

Use: Nasal moisturizing, congestion relief, allergy symptom management

No drug interactions. Safe for daily use. Particularly helpful in Arizona's dry desert climate. Helps flush allergens from nasal passages.

Digestive Health

Digestive issues are common when traveling or changing routines. These medications address the most frequent digestive complaints.

Antacids (Tums, Rolaids)

Generic: Calcium carbonate / magnesium hydroxide

Use: Heartburn, acid indigestion, upset stomach

Fast-acting. Calcium-based antacids also provide a calcium supplement. Do not use as a primary treatment for frequent or severe heartburn without physician evaluation.

Omeprazole (Prilosec OTC)

Generic: Omeprazole

Use: Frequent heartburn (2+ days/week)

Proton pump inhibitor. Takes 1–4 days for full effect. Not for immediate relief. Long-term use should be discussed with a physician.

Famotidine (Pepcid)

Generic: Famotidine

Use: Heartburn, acid reduction

H2 blocker. Faster acting than omeprazole. Can be taken before meals to prevent heartburn.

Bismuth Subsalicylate (Pepto-Bismol)

Generic: Bismuth subsalicylate

Contains salicylate — avoid if allergic to aspirin. Can temporarily turn stool and tongue dark/black (harmless). Do not give to children with viral illnesses.

Loperamide (Imodium)

Generic: Loperamide

Use: Diarrhea

Do not use if you have bloody diarrhea or high fever. Seek medical attention if diarrhea persists more than 2 days.

Gentle stool softener. Takes 1–3 days to work. Good option when straining should be avoided (after surgery, cardiac events).

Polyethylene Glycol (MiraLax)

Generic: Polyethylene glycol 3350

Use: Constipation

Osmotic laxative. Mixes into any beverage. Gentle and effective. Takes 1–3 days. Safe for most adults.

Skin, Wound Care & Topical

Arizona's sun, heat, and outdoor environment make skin care and wound care essentials for any household — especially for active snowbirds.

Hydrocortisone Cream 1%

Generic: Hydrocortisone

Use: Itching, rashes, insect bites, mild skin inflammation

Do not use on face, groin, or underarms without physician guidance. Do not use on infected skin. Short-term use only.

Triple Antibiotic Ointment (Neosporin)

Generic: Neomycin / polymyxin B / bacitracin

Use: Minor cuts, scrapes, burns — infection prevention

Apply thin layer to clean wound and cover with bandage. Some people develop allergic reactions to neomycin — if redness worsens, discontinue use.

Bacitracin Ointment

Generic: Bacitracin

Use: Minor wound care — alternative for those sensitive to neomycin

Good alternative to triple antibiotic for those with neomycin sensitivity.

Sunscreen SPF 30+

Generic: Various active ingredients

Use for the full recommended duration (usually 2–4 weeks) even if symptoms improve earlier.

Calamine Lotion

Generic: Calamine

Use: Itching from insect bites, poison ivy, chickenpox

Shake well before use. Apply to affected area and allow to dry. Safe for most adults and children.

Eye & Ear Care

Arizona's dry, dusty environment frequently causes eye irritation. These over-the-counter products address common eye and ear issues.

Artificial Tears (Systane, Refresh)

Generic: Carboxymethylcellulose or polyethylene glycol

Use: Dry eyes, eye irritation, dust and allergen flushing

Preservative-free formulas are gentler for frequent use (4+ times daily). Arizona's dry climate makes these a daily essential for many residents.

Antihistamine Eye Drops (Zaditor OTC)

Generic: Ketotifen

Use: Itchy eyes from allergies

Twice-daily dosing. Do not use while wearing contact lenses — wait 10 minutes after application before inserting lenses.

Ear Drops for Swimmer's Ear Prevention

Generic: Isopropyl alcohol / glycerin

Use: Prevention of swimmer's ear after water exposure

Apply a few drops after swimming or water exposure. Do not use if you have ear tubes or a perforated eardrum.

Carbamide Peroxide Ear Drops (Debrox)

Generic: Carbamide peroxide

Use: Earwax softening and removal

Do not use if you have ear pain, drainage, or a perforated eardrum. Consult a physician if symptoms persist.

Sleep & Mild Stress Support

Travel, schedule changes, and new environments can disrupt sleep. These are commonly used over-the-counter options — discuss with your physician before regular use.

Melatonin

Generic: Melatonin

Use: Sleep onset support, jet lag adjustment

Start with the lowest effective dose (0.5–1 mg). Higher doses (5–10 mg) are not necessarily more effective. Short-term use for schedule adjustment is generally well-tolerated.

Diphenhydramine Sleep Aids (ZzzQuil, Unisom)

Generic: Diphenhydramine

Use: Occasional sleeplessness

Not recommended for regular use in older adults — associated with increased fall risk, confusion, and next-day grogginess. Discuss chronic sleep issues with your physician.

Doxylamine (Unisom SleepTabs)

Generic: Doxylamine succinate

Use: Occasional sleeplessness

Same cautions as diphenhydramine. Avoid in older adults for regular use.

First Aid Supplies

A well-stocked first aid kit is essential for any household. These supplies handle minor injuries and emergencies until professional care is available.

Adhesive Bandages (Band-Aids)

Generic: Various sizes

Use: Minor cuts, scrapes, blisters

Stock a variety of sizes. Waterproof versions are useful for active individuals.

Sterile Gauze Pads & Rolls

Generic: Sterile gauze

Use: Wound dressing, bleeding control

Essential for larger wounds. Keep both 2x2 and 4x4 inch pads on hand.

Medical Adhesive Tape

Generic: Paper or cloth medical tape

Use: Securing dressings and bandages

Paper tape is gentler on sensitive skin.

Elastic Bandage (ACE Wrap)

Generic: Elastic compression bandage

Use: Sprains, strains, compression support

Do not wrap too tightly — check for numbness, tingling, or color changes below the wrap.

Digital Thermometer

Generic: Digital thermometer

Use: Temperature measurement

Oral, axillary, or tympanic (ear) thermometers are all acceptable. Normal adult temperature is approximately 97–99°F (36.1–37.2°C).

Blood Pressure Monitor

Generic: Automatic BP cuff

Use: Home blood pressure monitoring

Particularly important for those with hypertension or cardiovascular conditions. Measure at the same time each day for consistent readings.

Pulse Oximeter

Generic: Fingertip pulse oximeter

Use: Oxygen saturation and pulse rate monitoring

Normal SpO2 is 95–100%. Below 90% warrants medical attention. Useful for monitoring respiratory conditions.

Tweezers

Generic: Stainless steel tweezers

Use: Splinter and foreign body removal

Clean with alcohol before and after use.

Scissors (medical grade)

Generic: Bandage scissors

Use: Cutting bandages and tape

Blunt-tip bandage scissors are safer for cutting near skin.

Instant Cold Packs

Generic: Chemical cold pack

Use: Acute injury swelling, sprains, bruising

Apply wrapped in a cloth — never directly on skin. Use for 15–20 minutes at a time.

Isopropyl Alcohol 70%

Generic: Isopropyl alcohol

Use: Wound cleaning, surface disinfection

70% concentration is more effective as a disinfectant than 90%+ concentrations.

Hydrogen Peroxide 3%

Generic: Hydrogen peroxide

Use: Wound cleaning (use sparingly)

Current wound care guidelines suggest limited use — it can damage healing tissue. Saline or clean water is often preferred for wound irrigation.

Medication Storage Guidelines

Proper storage is critical for medication effectiveness and safety — especially in Arizona's extreme heat.

Store most medications at room temperature (59–77°F / 15–25°C)

Arizona's heat can degrade medications stored in vehicles or non-air-conditioned spaces.

Never store medications in the bathroom medicine cabinet

Humidity and temperature fluctuations in bathrooms can degrade medications faster.

Keep medications in original labeled containers

Labels contain critical dosing, expiration, and prescriber information.

Check expiration dates before traveling

Expired medications may be less effective or potentially harmful.

Refrigerate medications that require it

Insulin, certain eye drops, and some liquid medications require refrigeration. Check labels.

Keep medications out of direct sunlight

UV exposure can degrade many medications, particularly liquids and creams.

Bring a 30-day supply plus a 2-week buffer

Insurance may allow early refills for travel. Ask your pharmacist about travel overrides.

Drug Interactions & Polypharmacy

Many older adults take 5 or more prescription medications — a situation called polypharmacy. Adding over-the-counter medications to this mix can create drug interactions that range from mild to serious.

  • Always tell your pharmacist about ALL medications you take, including OTC drugs, vitamins, and supplements.
  • Ask your pharmacist to perform a medication review — this is a free service at most pharmacies.
  • Be especially cautious with blood thinners (warfarin, aspirin, Eliquis) — many OTC drugs interact with them.
  • NSAIDs (ibuprofen, naproxen) can interact with blood pressure medications and increase kidney risk.
  • Some supplements (fish oil, vitamin E, ginkgo) have blood-thinning effects.
  • Grapefruit juice interacts with many common medications — ask your pharmacist if yours is affected.
