Medicine overview

Tadalis-SX 20 mg is an oral tablet containing tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. The product is manufactured by Ajanta Pharma Ltd. Tadalafil is used to treat erectile dysfunction (ED), where a man has difficulty getting or maintaining an erection suitable for sexual activity. It supports the natural erectile response by increasing blood flow to the penis during sexual stimulation. The 20 mg strength is used as an as-needed tadalafil strength rather than the standard once-daily ED regimen.

What it is used for

Tadalis-SX 20 mg is used for erectile dysfunction in adult men. Tadalafil can help a man achieve and maintain an erection when sexual stimulation occurs. Tadalafil as an active ingredient also has approved uses for benign prostatic hyperplasia in certain formulations and dosing regimens, but those indications should not automatically be applied to this specific 20 mg branded product.

How it works

Tadalafil blocks phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP). During sexual stimulation, nitric oxide increases cGMP in erectile tissue. By slowing its breakdown, tadalafil promotes smooth-muscle relaxation and increased blood flow into the penis. This can improve the ability to develop and maintain an erection. Tadalafil does not produce an erection without sexual stimulation.

How it is taken

Tadalis-SX 20 mg is taken by mouth. For tadalafil used as needed for erectile dysfunction, it is taken before anticipated sexual activity and should not be taken more than once per day. Tadalafil may be taken with or without food. The 20 mg strength is not the usual once-daily ED dose; approved once-daily tadalafil regimens use lower strengths. Follow the prescriber's directions and do not combine tadalafil with other PDE5 inhibitors or erectile-dysfunction treatments unless specifically instructed.

Important warnings

Do not use tadalafil with nitrates such as nitroglycerin or isosorbide medicines because the combination can cause a dangerous fall in blood pressure. It is also contraindicated with guanylate cyclase stimulators such as riociguat. Medical assessment is important when cardiovascular disease makes sexual activity inadvisable. Tadalafil can further lower blood pressure when combined with alpha-blockers, antihypertensive medicines, or substantial alcohol intake. Strong CYP3A4 inhibitors, including ritonavir, ketoconazole, and itraconazole, can substantially increase tadalafil exposure. Kidney or liver impairment may require different dosing. Do not combine it with another PDE5 inhibitor. Seek emergency medical attention for an erection lasting more than 4 hours. Stop tadalafil and obtain prompt medical care for sudden vision loss or a sudden decrease or loss of hearing.

Side effects and monitoring

Common effects of tadalafil include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. Less common but potentially serious effects include prolonged erection (priapism), severe hypersensitivity reactions, marked low blood pressure, sudden hearing loss, and sudden vision loss associated with reported cases of non-arteritic anterior ischemic optic neuropathy (NAION). An erection lasting more than 4 hours requires emergency treatment. Sudden loss of vision or hearing requires prompt medical attention. Routine laboratory monitoring is not generally specified for tadalafil used for ED, although clinical assessment may be needed based on cardiovascular, kidney, liver, or other health conditions.

Pregnancy

Tadalis-SX for erectile dysfunction is not indicated for use in females. Human pregnancy data for tadalafil are insufficient to establish a drug-associated risk.

Breastfeeding

Tadalis-SX for erectile dysfunction is not indicated for use in females. There is no established information on tadalafil or its metabolites in human milk, its effects on a breastfed child, or its effects on milk production.

Food, drink and interactions

Avoid substantial alcohol consumption when taking tadalafil. Both alcohol and tadalafil can widen blood vessels, and consuming substantial amounts of alcohol with tadalafil can increase the risk of dizziness, headache, increased heart rate, and a fall in standing blood pressure.

Food and drink

Tadalafil may be taken with or without food. Food does not require a specific timing adjustment under approved tadalafil administration guidance. Substantial alcohol consumption should be avoided because it can increase blood-pressure-lowering effects.

Storage

Store tadalafil tablets at 20°C to 25°C (68°F to 77°F), with permitted excursions between 15°C and 30°C (59°F to 86°F), where specified by the applicable product labeling.

Frequently asked questions

How long before sex should tadalafil be taken?

Tadalafil used as needed is taken before anticipated sexual activity. An erection still requires sexual stimulation, and tadalafil has been shown to improve erectile function for up to 36 hours after a dose.

Does Tadalis-SX 20 mg work better if I take it on an empty stomach?

Tadalafil may be taken with or without food. Unlike some other PDE5 inhibitors, its approved administration instructions do not require an empty stomach.

Is 20 mg tadalafil meant to be taken every day?

The 20 mg strength is not the standard once-daily ED regimen. Approved once-daily tadalafil treatment for ED uses 2.5 mg or 5 mg, while 20 mg may be used as an as-needed dose when clinically appropriate.

Can I take another 20 mg tablet the next day?

Tadalafil used as needed should not be taken more than once per day. Follow the prescribed dosing instructions rather than taking extra doses because the previous dose did not produce the expected result.

What should I do if an erection lasts too long after tadalafil?

Seek emergency medical attention if an erection lasts more than 4 hours. Prolonged erection, or priapism, can damage penile tissue if treatment is delayed.

Can I drink alcohol with Tadalis-SX?

Avoid substantial alcohol consumption. Larger amounts of alcohol combined with tadalafil can increase dizziness, headache and the risk of a significant fall in blood pressure.

Can I take Tadalis-SX with nitroglycerin for chest pain?

No. Tadalafil must not be combined with nitrates such as nitroglycerin because blood pressure can fall to unsafe levels. Tell emergency healthcare professionals when tadalafil was last taken if you develop chest pain.

Does Cheap Generic Med ship Tadalis-SX internationally?

Cheap Generic Med serves multiple international destinations, including the United States, United Kingdom, Canada, Australia, Singapore, New Zealand, Japan and South Africa. Shipping availability does not establish that personal import is permitted; prescription and import requirements depend on the destination and individual circumstances.
