Allergic reactions to Erectile Dysfunction (ED): signs and what to do
Allergic reactions to medication range from mild rash to life-threatening anaphylaxis. Erectile Dysfunction (ED) (Erectile Dysfunction (ED)) is generally well-tolerated at 20mg, 100mg, 10mcg, 20mcg, 40mcg, but any active ingredient including Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil or its excipients can trigger an allergic response in a sensitised individual. Knowing what to watch for and how to act is part of safe use.
Recognising an allergic reaction
Mild reactions present as itching, localised rash, or mild flushing within hours of dosing. Moderate reactions add hives, swelling of lips or face, more extensive rash, or wheezing. Severe reactions — anaphylaxis — include rapid swelling of throat, difficulty breathing, drop in blood pressure, dizziness or collapse. Severe reactions are a medical emergency.
What to do
For mild reactions, stop Erectile Dysfunction (ED) and contact the prescriber for guidance — antihistamines may help symptomatically. For moderate reactions, stop the medication and seek same-day medical assessment. For any sign of anaphylaxis, call emergency services immediately. According to the prescribing information for Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil, a confirmed allergy contraindicates further use of Erectile Dysfunction (ED) at any 20mg, 100mg, 10mcg, 20mcg, 40mcg dose.
