Yes, a person with diabetes can generally use Climax Spray, as diabetes itself is not a contraindication to this medicine. Climax Spray contains lidocaine, a local anaesthetic that temporarily reduces penile sensitivity and may help delay ejaculation. However, people with diabetes should use it carefully and follow the instructions on the product label or their doctor's advice. If you have diabetic nerve damage, reduced genital sensation, or other sexual health concerns, it is advisable to consult your doctor before using the spray.
