TADAGA 40 MG (Tadalafil)

Tadaga 40 is a high strength tablet containing 40 mg of tadalafil.

Tadalafil belongs to the PDE-5 inhibitor drug class.

Listings name three different makers for this brand.

Those are RSM Multilink, RSM Enterprises and Samok Overseas.

Confirm the legal manufacturer from the physical carton.

The same molecule is sold under the brand name Cialis.

The Tadaga range also lists 5, 10, 20, 60 and 80 mg.

Only the Tadaga 5 mg, 10 and 20 mg strengths match approved doses.

Do not confuse Tadaga with Tadagra, a separate brand.

It is marketed to help men achieve and maintain a firm erection.

It works only when you are sexually aroused.

It does not increase sexual desire or libido.

It does not protect against HIV or other sexually transmitted infections.

It is not a contraceptive and does not prevent pregnancy.

The Tadaga 40 mg strength is twice the approved ED maximum.

A 40 mg daily dose is approved only for lung artery hypertension.

Use this strength only under direct medical supervision.

Sexual stimulation triggers the release of nitric oxide in penile tissue.

Nitric oxide raises levels of a messenger called cyclic GMP (cGMP).

Cyclic GMP relaxes the smooth muscle inside the corpus cavernosum.

Relaxed muscle allows more blood to flow into the penis.

Increased blood flow produces and maintains a firm erection.

An enzyme called PDE-5 normally breaks down cGMP.

Tadalafil selectively blocks the PDE-5 enzyme.

Blocking PDE-5 keeps cGMP levels higher for longer.

Blood vessels stay relaxed and erection quality improves.

Without sexual stimulation, tadalafil produces no erection.

Onset of effect is usually around 30 minutes.

Elimination half-life is approximately 17.5 hours.

Clinical effect can last up to 36 hours.

The liver enzyme CYP3A4 is the main metabolism pathway.

Excretion occurs mainly through faeces and partly through urine.

Blood levels rise broadly in proportion to the dose taken.

A 40 mg dose therefore gives roughly twice the 20 mg exposure.

PDE-5 enzyme blockade is already near maximal at approved doses.

Extra blood levels mainly add side effects, not erection quality.

No efficacy trial has tested 40 mg on demand for erectile dysfunction.

In lung hypertension trials, 40 mg daily was no better than 20 mg on walk distance.

A stronger dose does not mean a stronger or longer erection.

Every dose shown is from the approved tadalafil prescribing information.

The 40 mg lung hypertension row is a different disease entirely.

That regimen is daily therapy, not a tablet taken before sex.

Kidney, liver and interaction limits range from 5 mg to 10 mg.

This single tablet is four to eight times those limits.

A patient in any of those groups must not take this strength.

Never raise your own dose because a lower dose felt weak.

Poor response usually means the cause needs investigation instead.

This product is taken as needed, so missed doses rarely apply.

Never take two tablets to make up for one.

Never exceed one tablet in 24 hours.

Do not combine it with any other tadalafil product.

Contact a doctor or poison centre immediately after a suspected overdose.

Supportive care is the treatment; dialysis does not remove tadalafil.

Confirm with your doctor that this strength is right for you.

Ask whether a lower approved strength would suit you better.

Swallow the tablet whole with a glass of water.

Do not crush, split or chew the tablet.

Take the dose about 30 to 60 minutes before sexual activity.

You may take it with or without food.

Wait for sexual stimulation, as the dose alone will not work.

Allow at least 24 hours between two doses.

Do not combine it with any other ED medicine.

Tell your doctor if erections remain poor after several attempts.

A heavy, fatty meal may slightly delay the feeling of onset.

Effects can persist for up to 36 hours after one dose.

Side effects may also persist across that whole period.

Keep alcohol intake low to avoid dizziness and low blood pressure.

Rise slowly from sitting or lying for the first few hours.

Avoid driving until you know how the dose affects you.

Stop sexual activity and seek help if chest pain occurs.

Take any nitrate medicine, regularly or occasionally.

Use nitroglycerin, isosorbide mononitrate or isosorbide dinitrate.

Use recreational nitrites known as “poppers” (amyl or butyl nitrite).

Take riociguat or another soluble guanylate cyclase stimulator.

Are allergic to tadalafil or any ingredient in the product.

Had a serious hypersensitivity reaction to tadalafil before.

Had a heart attack within the last 90 days.

Had a stroke within the last six months.

Have unstable angina or angina during sexual intercourse.

Have uncontrolled high or very low blood pressure.

Have severe heart failure or uncontrolled irregular heartbeat.

Were told that sexual activity is unsafe for your heart.

Have lost vision before due to non-arteritic ischaemic optic neuropathy.

Have severe liver disease or severe kidney disease.

Are a woman, a child or a teenager below 18 years.

Any heart disease, chest pain, valve problem or past bypass surgery.

High blood pressure or low blood pressure.

Kidney disease or a history of dialysis.

Liver disease, hepatitis or cirrhosis.

Diabetes, especially if it is poorly controlled.

Stomach ulcers or any bleeding disorder.

Sickle cell anaemia, leukaemia or multiple myeloma.

Any penile deformity, such as Peyronie’s disease or curvature.

A previous erection lasting more than four hours.

Retinitis pigmentosa or any inherited eye disease.

Sudden vision loss or hearing loss in the past.

Benign prostatic hyperplasia or ongoing prostate treatment.

Any existing treatment for pulmonary arterial hypertension.

Poor response to standard 20 mg tadalafil doses.

Any antifungal or HIV medicine you take.

All prescription, herbal and over-the-counter products you use.

Food does not meaningfully change tadalafil absorption.

Avoid grapefruit and grapefruit juice while using this medicine.

Grapefruit can raise tadalafil blood levels further.

That risk matters more at a 40 mg strength.

Limit alcohol, as it worsens dizziness and lowers blood pressure.

Five or more alcohol units raise the risk of fainting.

Very fatty meals may delay the onset of the effect.

Avoid pomelo juice and Seville orange products as a precaution.

A lighter meal before the dose is preferable.

They are the closest published data to a 40 mg tadalafil dose.

Headache affected 15% of placebo patients and 42% on 40 mg.

No trial has measured 40 mg taken on demand for erectile dysfunction.
