Allergy Medication & Treatments

Allergies can be frustrating and even life threatening, but taking preventative measures to minimise exposure and risk, as well as knowing what to do if you do have an allergic reaction, can help you deal with them. Our online service offers Telfast hay fever tablets (fexofenadine hydrochloride) and if you suffer from allergies you know how annoying they can be. If over the counter hay fever tablets aren’t helping, then you may be able to get prescription strength tablets through our service.

Frequently asked questions

What does this treatment do?

These treatments help relieve symptoms of seasonal or environmental allergies, such as sneezing, runny or itchy nose, watery eyes, and itchy skin. They work by blocking the effects of histamine, the chemical responsible for triggering allergy symptoms, providing relief and improving daily comfort.

How do I use it for the best results?

Use the treatment as directed on the packaging or by your prescriber. Regular use at the recommended dose helps reduce allergy symptoms throughout the day. Combining treatment with simple preventive measures—such as avoiding known triggers, keeping windows closed during high pollen periods, and using protective clothing outdoors—can enhance relief.

What should I know while using these treatments?

Allergy treatments are generally safe and well-tolerated when used as directed. Some antihistamines can cause mild drowsiness, but there are less drowsy or non-drowsy options available for those who need to stay alert during the day. Always follow dosage instructions and do not exceed the recommended amount. If symptoms persist, worsen, or you experience unusual reactions, seek guidance from a healthcare professional.

How will I know if it’s working?

You should notice a reduction in sneezing, itching, runny nose, and watery eyes within a few hours for fast-acting treatments, and over a few days for longer-acting options. Continued use as directed helps maintain relief throughout allergy season or during exposure to triggers.

How do I start allergy treatment with IQ Doctor?

Starting is simple, quick, and safe: complete the online questionnaire and place your order. A qualified prescriber will review your answers, and once approved, your treatment is dispatched for next-day delivery (from the time your prescription is approved).
