Tadalafil (oral route)
It is essential that you inform all of your healthcare providers about your use of tadalafil. In cases where you require emergency medical assistance due to a cardiac issue, it is crucial that your attending physician is aware of the most recent time you ingested tadalafil. Having this information readily available can make a significant difference in your treatment and safety during emergencies.
For patients prescribed tadalafil to treat pulmonary arterial hypertension, regular follow-ups with your healthcare provider are imperative. These check-ups allow your doctor to monitor your response to the medication, ensuring its effectiveness and determining whether you should persist with the treatment. Depending on your situation, your physician may recommend blood and urine testing to identify any potential side effects or complications arising from the medication.
If you are using tadalafil specifically for pulmonary arterial hypertension, it is critically important that you do not also take Cialis® or any other PDE5 inhibitors, such as sildenafil (found in Revatio® or Viagra®) or vardenafil (Levitra®). This caution is due to the fact that Cialis® contains tadalafil as well. Combining these medications can significantly increase the risk of adverse side effects and complications.
In the event that you experience an erection lasting longer than 4 hours or a painful erection that persists for more than 6 hours, it is vital to contact your healthcare provider without delay. Such occurrences may necessitate immediate medical intervention to avert severe and potentially irreversible damage to the penile tissue.
This medication does not offer protection against sexually transmitted infections (STIs), including HIV and AIDS. It is important to use appropriate protective measures when engaging in sexual activities and to consult your healthcare provider if you have any inquiries or concerns regarding sexual health and safety.
You must be transparent with your physician about any existing or previous heart conditions. Tadalafil has the potential to cause serious complications for individuals with underlying cardiac issues.
Do not use tadalafil concurrently with riociguat (Adempas®) or any nitrate medications that are typically prescribed to alleviate angina (chest pain). Nitrate medications include nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitrostat®, Nitro-Dur®, Transderm Nitro®, Nitrol® Ointment, and Nitrolingual® Spray. Moreover, certain illegal substances, often referred to as "poppers"—such as amyl nitrate, butyl nitrate, or nitrite—also belong to the nitrate category. Should you need to use a nitrate medicine, ensure that at least 48 hours have passed since your last dose of tadalafil before administering it.
Limit your alcohol consumption while taking tadalafil; excessive intake (such as five or more glasses of wine or five or more shots of whiskey) can increase the likelihood of experiencing headaches, dizziness, a rapid heart rate, or decreased blood pressure. Moderation is key to reducing these risks and maintaining your overall well-being during treatment.
If you notice a sudden loss of vision in one or both eyes, it is crucial to seek medical attention immediately. Such symptoms could indicate a serious condition that requires prompt evaluation and care.
Additionally, you should notify your doctor right away if you experience a sudden decline in hearing or hearing loss, especially if accompanied by dizziness and ringing in the ears. These could be signs of a severe reaction to the medication that necessitates immediate investigation.
Avoid taking any other medications, including both prescription and nonprescription (over-the-counter [OTC]) drugs, as well as herbal or vitamin supplements unless you have consulted with your healthcare provider. This dialogue is important to prevent potential interactions and to ensure your treatment plan is safe and effective.
