Description
Vidalista 40 is a tadalafil 40 mg tablet. Tadalafil is part of a medicine group known as phosphodiesterase type 5, or PDE5, inhibitors. Medicines in this class affect blood vessel relaxation and are used in specific clinical situations, most commonly erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension depending on the product and prescribed regimen. Health Canada product information for tadalafil explains that it works only with sexual stimulation when used for erectile dysfunction and does not increase sexual desire. Because this strength is higher than the usual on-demand tadalafil dose used for erectile dysfunction in Canadian product information, it should not be used without professional guidance.About This Medicine
Tadalafil is used when a healthcare professional determines that a PDE5 inhibitor is appropriate. For erectile dysfunction, it helps support the natural erectile response by improving blood flow to the penis after sexual stimulation. Tadalafil may help relax muscles in the prostate and bladder for urinary problems associated with benign prostatic hyperplasia. Tadalafil is also used in some products to treat pulmonary arterial hypertension (PAH; high blood pressure in the arteries that go to the lungs). No information was given on the product-specific DIN, Canadian approval status and manufacturer of Vidalista 40. Check these details on the product label, at your pharmacy or in Health Canada’s Drug Product Database.How Tadalafil Works in the Body
Tadalafil blocks the PDE5 enzyme. This increases the effect of cyclic GMP, a natural chemical involved in relaxing smooth muscle and widening certain blood vessels. In erectile dysfunction, this supports improved blood flow to penile tissue when sexual stimulation occurs. In pulmonary arterial hypertension, tadalafil may help relax blood vessels in the lungs and reduce strain on the heart, depending on the prescribed product and diagnosis.Medical Uses
Tadalafil may be used for:- Erectile dysfunction: Helps improve the ability to get or maintain an erection when sexual stimulation is present.
- Benign prostatic hyperplasia: May reduce urinary symptoms linked with prostate enlargement.
- Pulmonary arterial hypertension: Some tadalafil products are prescribed for PAH under specialist supervision. The recommended tadalafil dose for the Canadian ADCIRCA product monograph is 40 mg once daily, but that does not mean every tadalafil 40 mg product is interchangeable.
Who Should Not Use This Medicine
Do not use this medicine if you have:- An allergy to tadalafil or any tablet ingredient.
- Current use of nitrates, such as nitroglycerin, isosorbide mononitrate, or isosorbide dinitrate.
- Use of recreational “poppers” containing amyl nitrite.
- Use of riociguat for pulmonary hypertension.
- A previous episode of NAION, a serious eye condition linked with sudden vision loss.
- Been told that sexual activity is unsafe because of heart disease.
How This Medicine Is Usually Taken
Vidalista 40 is taken by mouth as a tablet. The exact dose and timing must be decided by a prescriber. Canadian tadalafil information for erectile dysfunction describes on-demand dosing with 10 mg or 20 mg tablets, not more than once daily, while lower daily doses may be used for once-a-day treatment.Important dosage guidance
- Do not split, repeat, or increase the dose unless a healthcare professional advises it.
- If a dose is missed, ask a pharmacist or prescriber what to do based on why tadalafil was prescribed.

Is Vidalista 40 used for erectile dysfunction?
Tadalafil may be used for erectile dysfunction when a healthcare professional considers it appropriate. The 40 mg strength should be handled carefully because Canadian tadalafil information for erectile dysfunction commonly describes lower on-demand or daily dosing. Do not assume Vidalista 40 is suitable for ED without medical advice.
Can I take Vidalista 40 every day?
Daily use depends on the condition being treated, the exact product, and the prescribed dose. Some tadalafil products are used once daily at lower doses for ED or BPH, while PAH regimens may differ. Ask a prescriber or pharmacist before using tadalafil daily, especially at 40 mg.
What should I do if I miss a dose?
The right step depends on why tadalafil was prescribed. If it was prescribed for scheduled daily use, ask your pharmacist what to do. Do not take two doses together to make up for a missed tablet unless a healthcare professional specifically tells you to do so.
Can tadalafil be taken with alcohol?
Alcohol may increase dizziness, flushing, or low blood pressure effects. It may also make erectile dysfunction worse in some people. If you drink alcohol, keep intake modest and ask a pharmacist whether alcohol is safe for your health profile and other medicines.
Which medicines should not be combined with Vidalista 40?
Do not combine tadalafil with nitrates or riociguat. Use caution with alpha-blockers, blood pressure medicines, some antifungals, certain antibiotics, HIV protease inhibitors, and other PDE5 inhibitors. A pharmacist should check your medication list before tadalafil is used.
What side effects need urgent medical attention?
Seek urgent help for chest pain, fainting, sudden vision loss, sudden hearing changes, allergic reaction symptoms, or an erection lasting more than 4 hours. These effects are not common, but they can be serious and should not be ignored.
Is Vidalista 40 listed with a Canadian DIN?
The DIN was not provided in the product details. A DIN should be verified on the package or through a pharmacist. Health Canada’s Drug Product Database can be used to search authorized drug products and related product monograph information.
