Stop taking the medication immediately.

Seek urgent medical attention if you experience difficulty breathing, swelling of the face or throat, or a severe rash. These could be signs of a serious allergic reaction.

For mild reactions, consult a healthcare provider. They may recommend antihistamines or corticosteroids to manage symptoms.

Avoid self-medicating and do not take doxycycline or related antibiotics again without consulting your doctor.

Inform your healthcare provider about this reaction to document the allergy and discuss alternative treatments.
