Medications vs. Heat and Sun Exposure

When the weather in San Carlos (and elsewhere) warms up, it’s important to remember that some medications make you more sensitive to heat and sun than you would normally be. Increased sensitivity to heat can mean anything from a reduced ability to sweat to an increase in the amount of fluid you lose through your urine. The dehydration and overheating that can result may lead to cramps, exhaustion, and even heat stroke. Increased sensitivity to sunlight can result in rapid and severe sunburns (especially lately, when the UV index has been extreme!)

The list of medications to watch for is too long to publish but be aware that antibiotics can cause photosensitivity which can result in bad sunburns or skin conditions. Some antihistamines have been known to reduce the ability to sweat, resulting in overheating.

In addition to antibiotics and antihistamines, some painkillers; many psychiatric medications (including antipsychotics and antidepressants); blood pressure medications; cholesterol lowering agents and even some over-the-counter vitamins or supplements can affect your ability to withstand heat and sun exposure. It’s important to learn what heat or sun related side effects your medications might have. Your best resources are your physician or pharmacist, but there are also good online resources such as:

What can you do to avoid a problem? Here are some sensible measures you can take, even if you aren’t at increased risk due to medications:

  • Stay hydrated with non-alcoholic and non-caffeinated drinks throughout the day.
  • When you’re outdoors use sunscreen, reapplying often, and cover up with sun-protective clothing and a wide-brimmed hat.
  • If possible, stay in the shade or avoid being outdoors in the early afternoon, when the sun’s rays are at their peak. Staying in air-conditioned areas is recommended.
  • Do your outdoor activities in the morning or evening when the weather is cooler.
  • Learn the signs of heat illness which include headache; racing pulse; rapid breathing or feeling light-headed, nauseated, or weak. If these symptoms occur, you may need emergency assistance, so contact your local physician or Rescate as soon as possible. In the meantime, move to a cool location, take a cool shower, bath or sponge bath and drink plenty of fluids.

Remember Rescate can’t be reached at 911. In an emergency dial 226-0911 or, from a US or Canadian cell, 011 52 (622) 226-0911.

Preparing for a Summer Hike

As we all know the weather in San Carlos from June through September can be brutally hot and humid. However, it is still a beautiful place that should be experienced and enjoyed; just a little more cautiously during the summer months when the sun and heat can pose health risks when combined with vigorous exercise.

If you’re planning to climb Tetakawi or to hike Nacapule Canyon or other trails, Rescate offers some tips to ensure you head out well prepared to be safe and to enjoy your day:

  • Try to restrict your hikes to morning or late afternoon hours to avoid the heat of the day.
  • Before you leave on your hike, slather on some sunscreen (SPF 30 or higher) and carry it with you to reapply during the hike. Remember to cover all exposed skin and to protect your lips as well.
  • Wear clothing that covers as much skin as possible. Be sure it’s made of a material that breathes, such as 100% cotton. Better yet, wear Ultraviolet Protection Factor (UPF) clothing. Remember your sunglasses, a wide-brimmed hat to protect your face, ears and neck, and solid footwear to protect your feet and ankles.
  • Carry more water than you think you need and turn back when it’s half gone. Keep extra water in your vehicle to rehydrate after your hike.
  • Add electrolytes to your water or carry prepared sports drinks as well as water. The extra vitamins and minerals will help prevent leg cramps and reduce fatigue.
  • Carry and consume high protein snacks such as nuts or protein bars.
  • Take rest breaks, preferably in the shade, when possible.
  • Remember to bring your fully charged cell phone. Besides being a communication device it’s your camera, GPS, compass and flashlight.
  • During the hike watch where you put your feet to avoid hazards such as loose rocks or roots. This will also help you avoid “live” threats such as snakes, scorpions and spiders.
  • Carry a first aid kit so you have supplies for any injury. It should include bandages, gauze, antibacterial ointment, cotton swabs, tissues, alcohol wipes, and hand sanitizer.

Enjoy your hike and stay safe!

Treating Stingray Stings

Stingrays are common in the San Carlos area, and are often buried in the sand at the shore. They are not aggressive and stings usually occur when a swimmer or diver accidentally steps on one. To avoid this, always shuffle your feet when walking in the sea to warn them you’re in the area.

Stingray injuries almost always need to be checked by a health care worker but first aid measures should be started at the scene. Care of the injured person begins with a safe removal of the victim from the water.

If the stingray injury is in the abdomen, chest or head, call a Rescate ambulance immediately at 226-0911, or from a US or Canadian cell phone it may be necessary to dial 011 52 (622) 226-0911. Remember that Rescate cannot be reached by dialing 911!

If the injury is to a foot, leg, hand or arm, administer the following first aid and come to the Rescate infirmary as soon as possible.

  • Lay the person down and flush the wound with sea water or fresh water if available.
  • You may attempt to remove the stinger with tweezers to decrease toxin exposure if it will not cause further harm. Be careful not to injure yourself with the stinger.
  • Apply pressure with a clean towel or clothing to stop the bleeding.
  • Wash the wound with soap and fresh water.
  • For pain relief, soak the wound in water as hot as the injured person can tolerate (preferably about 110° F or 43.3° C) for up to 90 minutes.

If the patient develops severe symptoms such as difficulty breathing; swelling or tightness in the throat; itching; nausea; rapid pulse; dizziness or loss of consciousness call Rescate immediately.

Safe Disposal of Medications

Safe disposal of medications is not a subject most of us spend much time thinking about, but it’s important. Medications that are still active can be eaten by children who mistakenly think it’s candy, resulting in accidental poisoning. They are also sought after by “thrill seekers” or addicts who obtain and combine prescription meds in an effort to get high. Expired medications that are no longer effective can be equally dangerous if someone who really needs them takes them and they don’t have the desired or required effect.

In San Carlos, where many people spend only part of the year, it can be tempting to store medications from one year to the next. Rescate suggests that you periodically go through your medications, both over-the-counter and prescription, and dispose of expired or unneeded items.

For environmental reasons, flushing medications down the sink or toilet is rarely recommended. There are several safe methods of disposal:


  1. There are permanent (usually in pharmacies) and periodic take back and mail back programs in the States. The DEA website is a great source of detailed information. In Canada all pharmacies will take back unwanted medications at any time. Unfortunately this method of disposal requires you taking medications “up north” since Mexico does not have a similar program.
  2. If you want to dispose of medications here in Mexico you can remove the meds from their containers and mix them with an unpleasant material such as cat litter, dog droppings or coffee grounds. Place this mixture in a sealed plastic bag and dispose of it with your household waste. It is not necessary or advisable to crush or grind the meds up first.
  3. There are a few prescription medicines that contain controlled substances (including opiates, tranquilizers and some pain medications) that are very harmful if taken accidentally. As a result, these medications can be disposed of by flushing them down the sink or toilet when they are no longer needed and take-back options are not readily available. According to the FDA, while this is not advised for most medications, in these cases the risks to a child, adult or animal outweigh the environmental impact. Canadian authorities disagree, out of concern for marine life, and strongly recommend all medications be returned to pharmacies for incineration.

Once your medications are safely disposed of remember to remove or black out all personal information, including the bar code, on the prescription label before throwing out your empty pill bottle or other packaging.
