If you're searching for answers about low testosterone (Low T) and erectile dysfunction (ED), you've come to the right place.

Hi-Doctor connects you with qualified medical professionals who can assess your case. The online consultation is just €25, and if treatment is deemed appropriate, you receive a valid EU prescription (REMPE) within 24 hours, accepted at any pharmacy across the EU.

Who qualifies for Low T or ED medication

Our EU-licensed doctors carefully evaluate each patient's medical history to determine if treatment for low testosterone or erectile dysfunction is appropriate. They look for specific criteria, including blood test results indicating low testosterone levels (typically below 300 ng/dL), and symptoms such as reduced libido, fatigue, decreased muscle mass, and difficulty achieving or maintaining erections. The doctor will also assess for contraindications, such as certain cardiovascular conditions, prostate issues, or other health concerns that might make specific treatments unsuitable. Your comprehensive online questionnaire helps the doctor understand your health profile and make a safe, informed decision.

What the medication actually does (and doesn't do)

Medications for low testosterone, primarily Testosterone Replacement Therapy (TRT), aim to restore your testosterone levels to a healthy range. This can significantly improve symptoms like low libido, ED, fatigue, and mood disturbances. TRT works by supplementing the body's natural testosterone production. For ED specifically, medications like sildenafil and tadalafil increase blood flow to the penis, facilitating an erection when sexually stimulated. It's important to understand that these medications don't create spontaneous erections; they require sexual arousal to be effective. Results vary per individual, and consistent use as prescribed is key. These treatments address symptoms but do not cure the underlying causes of low testosterone or ED in all cases.

Side effects and when to stop

Like all medications, treatments for low testosterone and ED can have side effects. For TRT, common side effects can include skin reactions (acne), fluid retention, and changes in red blood cell count. Less common but serious risks include sleep apnea or prostate enlargement. ED medications like sildenafil or tadalafil can cause headaches, flushed skin, indigestion, or nasal congestion. In rare cases, more serious side effects like sudden vision loss or hearing loss can occur. It's crucial to follow your doctor's instructions precisely and report any unusual or severe side effects immediately. If you experience chest pain, a prolonged erection (priapism), or severe allergic reactions, seek emergency medical attention. Your Hi-Doctor will provide detailed information on potential side effects and guide you on when to discontinue treatment.
