Turn “it did not work” into a useful follow-up note

Start with the exact prescription

A useful message begins with the medication name, formulation and directions on the label. Say whether you followed those directions and whether any part was uncertain. If a pharmacy changed the package or the wording looks different from the website, mention that too. The clinician needs to know which product you actually received, not just which brand's advertisement brought you there.

Do not use the follow-up note to design a new dose. Both sildenafil and tadalafil patient information direct people to take the medicine as prescribed and tell the clinician if it is not working well or causes side effects. That conversation can lead to reassessment; it is not an invitation to double a dose, combine products or borrow someone else's prescription. [Sildenafil] [Tadalafil]

Describe the outcome without assigning a cause

Was it difficult to get an erection, maintain it, or both? Was the experience different from before treatment? Did discomfort, anxiety, a side effect or an unclear instruction get in the way? Brief factual notes are more useful than deciding that a medicine is universally weak or that you have a particular underlying condition.

You can also report changes in other medicines or health conditions since the original assessment. ED can have several contributing causes, and the diagnostic process may include more than a prescription discussion. Ask whether the new information changes the need for an examination, tests or a referral. [NIDDK]

Separate routine follow-up from urgent care

A subscription message queue is not an emergency service. An erection lasting longer than four hours needs urgent medical attention. Sudden hearing or vision loss requires immediate medical attention and no further ED medication until medical advice. Call emergency services for chest pain, severe breathing difficulty or fainting. Tell the treating team which medicines you have taken.

Read the full medication information supplied with your own prescription and ask the pharmacist to explain its emergency instructions. This guide lists important examples rather than every possible reaction. If symptoms feel serious, seek medical help instead of waiting for the next scheduled review.

Finish with one clear request

For a routine message, try: “Could you review whether this is the right treatment for me and explain the next step?” Ask who will respond, how follow-up is arranged and whether it costs extra. Keep a copy of the reply with your prescription details so the plan is easy to find later.

If tablets are unsuitable or have not helped, there may be other approaches to discuss. NIDDK describes counseling, devices, injections and selected surgical options, depending on the situation. Our guide to treatment beyond tablets introduces those conversations without suggesting that one next step fits everyone. [NIDDK treatment]
