Insect Bites, Tick Bites, and Allergic Reactions in Croatia: When to See a Doctor
Quick answer
Most insect bites and stings cause only mild redness, itching, or swelling. However, worsening swelling, signs of infection, or significant allergic symptoms may need medical attention. At CissaMed in Novalja, our team can assess insect bites, stings, tick bites, and non-life-threatening allergic reactions. If you develop difficulty breathing, swelling of the tongue or throat, fainting, or other signs of a severe allergic reaction, call 112 immediately.

Mosquitoes, wasps, bees, ticks, and other insects are a normal part of spending time outdoors during summer in Croatia.
Most bites and stings are uncomfortable rather than dangerous. Sometimes, however, swelling becomes much larger than expected, the skin becomes infected, or an allergic reaction develops.
Knowing which symptoms can usually be monitored and which require medical attention can help you decide what to do next.
What is a typical local reaction?
A mild local reaction may include:
- redness
- itching
- mild swelling
- tenderness
- pain or a burning sensation around the affected area
These symptoms often improve gradually.
Try to avoid scratching itchy bites because damaged skin can make it easier for bacteria to enter and cause an infection.
A cold compress may help reduce local discomfort and swelling.
When is swelling more concerning?
Some people develop a larger local reaction after an insect bite or sting.
The swelling may continue to increase over several hours and extend beyond the immediate area of the bite.
A large local reaction does not automatically mean that someone is experiencing a severe allergic reaction. However, it is a good idea to seek medical advice if the swelling is significant, continues to increase, becomes very painful, or simply concerns you.
At CissaMed, our doctor can examine the affected area and assess whether treatment is necessary.
How can you recognise possible infection?
Increasing warmth, redness, tenderness, pus, swollen glands, or flu-like symptoms can suggest that the skin has become infected.
What about tick bites?
Ticks require slightly different attention from mosquito bites or insect stings.
If you find a tick attached to your skin, it should be removed carefully and as soon as possible.
If you are unsure how to remove it properly, part of the tick remains in the skin, or you are concerned about the bite, you can visit CissaMed for an assessment.
After a tick bite, continue to observe the area and your general health.
Seek medical advice if you later develop concerning symptoms such as a spreading rash, unexplained fever, unusual fatigue, or other symptoms that make you feel unwell.
What are the warning signs of anaphylaxis?
A severe allergic reaction, known as anaphylaxis, can develop rapidly and can be life-threatening. Warning signs may include:
- sudden swelling of the lips, tongue, mouth, or throat
- difficulty breathing
- wheezing or noisy breathing
- difficulty swallowing
- severe dizziness
- fainting or loss of consciousness
- confusion
- a rapidly worsening general condition
Suspected anaphylaxis is an emergency. If you or someone with you develops these symptoms, do not wait to visit an outpatient clinic. Call 112 immediately.
If the person has a prescribed adrenaline auto-injector, use it according to their emergency treatment plan while emergency medical help is being arranged.
