Symptoms of a Cottonmouth Snake Bite

Cottonmouth snake bite symptoms fall into two categories – localized and systemic symptoms. (Another snake that packs a potent bite is the black mamba.)

Localized Symptoms

#1 Pain and Swelling 

The pain and swelling at the bite site can be intense and may start within minutes of the bite. The affected area may also become discolored and swollen, with the skin wearing a bluish or purplish hue. 

This is due to the venom’s ability to break down the walls of blood vessels, causing them to leak into surrounding tissues. 

#2 Bruising and Discoloration of the Skin

Sometimes, the bite site may also develop blisters and necrotic tissue. The degree of swelling and discoloration resulting from a cottonmouth snake bite can vary depending on factors such as the amount of venom injected, the location of the bite, and the individual’s reaction to the poison.

It is important to note that not all bites from a cottonmouth snake will result in the same symptoms.

Systemic Symptoms

#1 Nausea and Vomiting

In addition to localized symptoms, cottonmouth snake venom can cause nausea and vomiting, posing a severe risk if the victim inhales their vomit.

#2 Difficulty Breathing

In some cases, the venom can cause respiratory distress, leading to breathing difficulties or even respiratory failure.

#3 Rapid Heartbeat

The venom can cause an increase in heart rate, which can be especially dangerous for those with pre-existing heart conditions.

#1 First Aid

Stay Calm and Seek Immediate Medical Attention

If a cottonmouth snake bites you, it is crucial to remain calm and seek immediate medical attention to avoid complications or potentially life-threatening situations. Do not try to capture or kill the snake, this will put you at the risk of falling victim to another bite.

Clean and Cover the Bite Wound

After seeking medical attention, cleaning the bite wound with soap and water and covering it with a sterile bandage can help prevent infection and promote healing.

Keep the Affected Limb Immobilized

Keeping the affected limb at or below heart level can help prevent the venom from spreading and is essential after a cottonmouth snake bite.

#2 Medical Treatment

Administration of Antivenom

 Antivenom is a type of medication that can neutralize the effects of the venom. Receiving antivenom as soon as possible after being bitten by a cottonmouth snake is crucial and can significantly increase the chances of a successful recovery.

Pain Management

Administration of pain medications may help manage pain and discomfort.

Wound Care

The bite wound may require debridement or surgical intervention, depending on the severity of the bite.

Observation and Monitoring

Individuals bitten by a cottonmouth snake will typically be admitted to the hospital for observation and monitoring to ensure that their condition remains stable and that any necessary treatments are administered promptly.

During this time, medical professionals will monitor the victim’s vital signs and symptoms and provide any necessary medical treatment, such as antivenom administration or pain management. 

The duration of hospitalization after a cottonmouth snake bite is not fixed. It varies based on several factors:

  • the severity of the bite
  • the individual’s response to treatment
  • other relevant factors

Some patients may need a more extended stay than others due to the quantity of venom injected, the location of the bite, and the efficacy of the antivenom and other interventions administered.


Following a cottonmouth snake bite, physical therapy and rehabilitation may be required to assist the victim in recovering their mobility and strength. Depending on the severity of the bite, the individual may experience limited mobility, weakness, or muscle atrophy. 

Physical therapy for a cottonmouth snake bite may involve a range of exercises to improve the victim’s range of motion and strength and balance training. Rehabilitation can take several weeks or even months, depending on the individual’s progress and the extent of their injuries. 

Individuals must work closely with their healthcare providers to develop a comprehensive rehabilitation plan and follow through with all recommended treatments and exercises.

Experiencing a cottonmouth snake bite can be a traumatic event that may lead to anxiety and fear. Seeking psychological support when necessary is crucial in helping victims deal with the emotional aftermath of the experience.

To manage anxiety and fear after experiencing a cottonmouth snake bite, it can be helpful to consult a mental health professional or counselor who can provide coping strategies and emotional support.

Chronic Pain and Disability

In some cases, the victim of a cottonmouth snake bite may experience ongoing pain and disability. This can be due to nerve damage, tissue damage, or other complications arising from the bite.
