Tadalafil (oral route)
It is important that you tell all of your doctors that you take tadalafil. This information is crucial, as it helps them manage your overall health care effectively. If you ever find yourself in a situation where you need emergency medical assistance for a heart-related issue, your doctor will need to know precisely when you last took tadalafil in order to provide the best possible care and avoid any potential complications.
In the case that you will be using this medication for pulmonary arterial hypertension, it is very important that your healthcare provider monitors your progress at regular intervals. Regular check-ups will allow your doctor to assess the medication's effectiveness and determine whether it is appropriate for you to continue your treatment. This ongoing evaluation may include blood and urine tests to identify any unwanted side effects that may arise from the medication.
Furthermore, if you are taking tadalafil specifically for pulmonary arterial hypertension, you must avoid the use of Cialis® or other phosphodiesterase type 5 (PDE5) inhibitors, including sildenafil (known by brand names such as Revatio® or Viagra®) and vardenafil (commonly referred to as Levitra®). It is important to note that Cialis® also contains tadalafil, and taking too much tadalafil or combining it with these other medications can significantly increase the risk of adverse effects.
If you experience a prolonged erection lasting longer than 4 hours or a painful erection lasting more than 6 hours, you should seek immediate medical assistance. Ignoring this condition may require urgent medical intervention to prevent severe and permanent damage to the penile tissue.
This medication does not provide any protection against sexually transmitted infections (STIs), including HIV or AIDS. It is advisable to utilize protective measures during sexual intercourse, and you should consult your doctor should you have any questions or concerns regarding this issue.
In addition, it is essential to inform your healthcare provider about any current or previous heart conditions. Tadalafil has the potential to induce serious side effects in individuals with a history of heart problems, thus warranting careful consideration and monitoring.
Please refrain from using this medication in conjunction with riociguat (Adempas®) or any nitrate medications, which are often prescribed for angina (chest pain). Examples of nitrate medications include nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitrostat®, Nitro-Dur®, Transderm Nitro®, Nitrol® Ointment, and Nitrolingual® Spray. Additionally, certain illicit substances known as “poppers” (like amyl nitrate, butyl nitrate, or nitrite) also contain nitrates. If a nitrate medication is necessary, ensure that at least 48 hours have passed since your last dose of tadalafil before taking it.
It is also advisable to limit alcohol consumption while using tadalafil; excessive intake (for example, 5 or more glasses of wine or 5 or more shots of whiskey) can lead to increased likelihood of experiencing headaches or dizziness, elevated heart rate, or a decrease in blood pressure.
If you suddenly lose vision in one or both eyes, you must contact your doctor without delay. This could be a serious condition that requires immediate attention.
Should you notice a sudden decrease in hearing or complete loss of hearing, often accompanied by dizziness and ringing in the ears, seeking medical advice right away is crucial. Time is of the essence in such situations to manage potential complications.
Finally, do not take any other medications without first discussing them with your healthcare provider. This includes any prescription or over-the-counter (OTC) medications as well as herbal or nutritional supplements, which could interact with tadalafil and compromise your health.
