What is Befar 0.4% Eye Drops?

Befar 0.4% Eye Drops is a prescription product containing alprostadil 0.4% in each tube. Alprostadil is a prostaglandin medicine used in men’s health to help improve erectile function when blood flow support is needed. Befar 0.4% Eye Drops is intended for use only as directed by a healthcare professional, and this higher-strength formulation is not for self-selection. It is supplied as a strip/box of 10 tubes from GSK, UK.

How it works: Alprostadil works by helping widen blood vessels and increase blood flow in the penis, which can support an erection when sexual stimulation is present. In this eye-drop-labeled product line, the same active ingredient is delivered in the exact 0.4% tube strength prescribed by your clinician.

Why choose Befar 0.4% Eye Drops?

Befar 0.4% Eye Drops is a higher-strength alprostadil presentation, so it is generally suited to patients whose doctor has decided they need a stronger option rather than a lower-strength product. Because there are no sibling strengths or forms listed for this brand, the 0.4% eye drop should be viewed as the specific formulation available in this product line and used only under medical guidance.

Uses of Befar 0.4% Eye Drops

  • Erectile dysfunction treatment
  • Men’s health prescription support
  • Improving penile blood flow
  • Use only when prescribed by a doctor

How to take Befar 0.4% Eye Drops

  • Use Befar 0.4% Eye Drops exactly as your prescriber tells you; do not change the tube amount or frequency on your own.
  • Follow the package instructions for the eye-drop tube format and never use it more often than prescribed.
  • Use only the full dose your doctor selected; this 0.4% strength is not meant to be split or adjusted casually.
  • Do not take extra doses if the effect is not strong enough unless your doctor specifically instructs you to do so.
  • If you are unsure how to handle or administer the tube, ask a pharmacist or prescriber before using it.

Befar 0.4% Eye Drops dosage

Befar 0.4% Eye Drops provides alprostadil at 0.4% per tube, which is a higher-strength presentation than a lower-dose starting option would be. The exact amount used, how often it may be taken, and the maximum number of doses per day must be set by the doctor based on your response and safety; do not exceed the prescribed schedule.

Do not change your dose or stop the medicine without speaking to your doctor.

Precautions and warnings
