Vardenafil (oral route)
It is vital that you inform all healthcare providers involved in your care that you are taking vardenafil. If you find yourself in a situation requiring emergency medical assistance due to a heart-related issue, it becomes crucial for your medical team to be aware of the timing of your last dose of vardenafil. This information can be critical in managing your care safely and effectively.
Moreover, do not use this medication in conjunction with any nitrate-containing medicines prescribed for conditions such as angina or high blood pressure. Examples of such nitrates include nitroglycerin, isosorbide, and various formulations like Imdur®, Nitro-Bid®, Nitro-Dur®, Nitrol® ointment, Nitrolingual® spray, Nitrostat®, as well as transdermal patches. Additionally, be aware that some illicit substances referred to as "poppers" may also contain nitrates, including amyl nitrate and butyl nitrate. It is imperative to avoid using vardenafil if you are concurrently prescribed riociguat (Adempas®), as the interactions can be potentially harmful.
If you encounter an erection lasting more than 4 hours or experience pain during an erection, seek immediate medical attention. This condition, known as priapism, necessitates prompt intervention to avert serious and possibly irreversible damage to the penis, which could affect both physical health and overall quality of life.
Be vigilant for any sudden loss of vision in one or both eyes; if this occurs, reach out to your healthcare provider immediately. Vision changes can be an indication of serious underlying conditions that require timely assessment and intervention.
Additionally, if you begin to experience a sudden decrease in hearing or any hearing loss accompanied by symptoms like dizziness or tinnitus (ringing in the ears), you should consult your doctor without delay. These symptoms can be indicative of rare but serious side effects associated with this medication.
If you are currently managing hypertension with other prescribed medications, understand that vardenafil has the potential to lower your blood pressure significantly. Be alert for signs like blurred vision, confusion, dizziness, faintness, or light-headedness, especially when transitioning from a lying or sitting position to standing. Symptoms such as excessive sweating or an unusual sense of fatigue or weakness should also prompt you to contact your healthcare provider immediately.
Moreover, it's crucial to remember that this medication does not provide any protection against sexually transmitted infections (STIs), including HIV and AIDS. Always engage in safe practices and do not hesitate to discuss any concerns regarding STIs with your healthcare provider.
Lastly, you should refrain from taking any other medications without first consulting your doctor, including both prescription and nonprescription (over-the-counter) drugs, as well as herbal supplements or vitamins. Ensuring that your healthcare provider is aware of all substances you are taking can help in avoiding dangerous interactions.
