Severe Skin Rash or Hives
Hives or severe skin rashes are allergic reactions that can manifest in various sizes and shapes, often as itchy, inflamed red bumps, or large patches of skin flakiness or peeling.
Anaphylaxis
Anaphylaxis is a serious allergic reaction. The symptoms can include a rapid heartbeat, low blood pressure, difficulty breathing, dizziness or unconsciousness, and intense nausea or vomiting.
Swelling of the Face, Lips, or Tongue
These are signs of a potential severe allergic reaction. The swelling can significantly interfere with breathing and require immediate medical attention.
Stomach Cramping or Diarrhea
This can be a symptom of an allergic reaction to tetracycline antibiotics and can range from mild discomfort up to severe cramping and diarrhoea.
Difficulty Swallowing or Breathing
These symptoms may indicate that the allergic reaction is affecting the respiratory system, which can potentially be life-threatening if not promptly treated.
Severe Headache or Blurry Vision
These symptoms might be associated with intracranial hypertension, a condition that can occur in some patients taking tetracyclines. It requires immediate medical attention.
