1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.

irlwinds. (erennial type BPH medication) feddley SEB 2019: 23: 50I’ve been taking tadalafil citrate for over 20 years now. Been using it for 2 months now and have nothing. Can’t take it as prescribed. Does anybody experienced side effects or have any advice?
Hi, I’ve been on tadalafil citrate medication for about 2 years now and am having the same feeling. Does anyone know a safe dose for the symptoms? I’ve heard it’s best to take it at the first sign of any side effects, like dizziness or lightheadedness, before considering a treatment.
Thank you for your email!
Best wishes on your health

I’ve been on tadalafil citrate for about 5 years and am still having ED. I think I need to switch to tadalafil citrate because I can’t tolerate tadalafil. Tadalafil is an FDA-approved medication for Erectile Dysfunction. My doctor told me to take it at the first sign of any problem, like dizziness or lightheadedness, before sexual activity. Is that right?

Hi Jannette,
I was prescribed tadalafil for an enlarged prostate as well. My doctor advised me to take it as needed, but I stopped taking it because of the side effects. Tadalafil can sometimes cause dizziness and lightheadedness, so I’m not sure if that’s the case. Should I take tadalafil for ED?
- Hana
Tadalafil can sometimes cause dizziness and lightheadedness, so if you’re feeling drowsy, take it as soon as you can. But if you’re feeling dizzy or lightheaded, don’t take it right away. Tadalafil should be taken at the first sign of any side effects, like dizziness or lightheadedness, before sexual activity. Tadalafil for ED is a medication that’s been approved by the FDA for treating Erectile Dysfunction (ED), which means it’s FDA-approved for ED in men.
For more detailed information, including how to take it for optimal results, consult the Patient Information Leaflet. You can also read it every time a refill is needed.
