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.
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.
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:
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.
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)

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.

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

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: PseudoephedrineUse: 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: PhenylephrineUse: 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 sprayUse: 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 issues are common when traveling or changing routines. These medications address the most frequent digestive complaints.
Antacids (Tums, Rolaids)

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 glycolUse: 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.

70% concentration is more effective as a disinfectant than 90%+ concentrations.
Hydrogen Peroxide 3%
Generic: Hydrogen peroxideUse: 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.
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.
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.
