What cream or spray to buy for insect/sea lice bites in Nha Trang?

Many travelers get unclear bite marks (possibly from sea lice/plankton) — the marks last a long time and it's often unclear what caused them.

Applying the ointment frequently reduces itching, though the marks themselves take a while to heal.

You can ask at local pharmacies for sprays and ointments specifically for insect bites — they're sold over the counter without a prescription.

For allergic reactions to bites, Fucicort ointment works well and relieves itching almost instantly; Fenistil gel is another good option.

Avoid scratching bite marks — it only worsens the irritation. Fresh lime juice can help ease the burning right after a bite.
