Scope and a sweeping overview of the material plus quick facts
This page summarises information about sublingual formulations of tadalafil, commonly referred to as "Cialis Sublingual". These products are intended to dissolve under the tongue and are used to aid erections in men with erectile dysfunction. Tadalafil works by inhibiting phosphodiesterase type 5 (PDE5), which can increase blood flow to the penis during sexual stimulation.

- Indication: problems with erections (ED)
- Common sublingual strength on some markets: tablets with a dose of 20 mg; dosing should be tailored to the individual
Note: In the UK many sublingual tadalafil preparations are not licensed by the Medicines and Healthcare products Regulatory Agency (MHRA). For licensed options and safer choices, see Buying in Britain and its status of legal compliance.
What it is for and how it functions
Tadalafil is prescribed to improve the ability to get and keep an erection sufficient for sexual activity. It does not raise libido and requires sexual arousal to be effective. Compare the twod with some other PDE5 inhibitors, tadalafil has a longer duration of action; some people find sublingual administration gives a faster perceived start.
For potential adverse reactions, see Latent effects. If you need contraindication information, go to Warning notices and preventive measures.
How to take pills safely Cialis Sublingual
Below are general directions commonly recommended for on-demand sublingual tadalafil. Always follow the instructions from a prescriber or the product leaflet.
- Timing: Many people take one tablet about 15 to 30 minutes before sexual activity.
- Administration: Place the tablet under the tongue and allow it to dissolve fully; avoid swallowing immediately or consuming very hot drinks while it dissolves.
- Food: Sublingual absorption may be less affected by meals than swallowed tablets, but very heavy meals can still delay effect.
- Starting dose: Although some sublingual products are supplied as twenty-milligram tablets, clinicians may advise a lower effective dose. Discuss options such as smaller tablets or licensed multiple options with your healthcare professional.
- Within any 24 hour period, take no more than one dose.
If you prefer a daily low dose, licensed oral tadalafil tablets are available as 2.5 mg or 5 mg once-daily options. See Options and evaluative comparisons for additional modalities of treatment.
Missed dosing parameters and guidance

Guidelines for storage capacity can limit how much you can keep on hand.

- You have a history of certain eye problems, for example non-arteritic anterior ischemic optic neuropathy (NAION) or inherited retinal disease.
Key dynamics to consider:
- Powerful CYP3A4 inhibitors such as ketoconazole, itraconazole or some HIV protease inhibitors can raise tadalafil levels.

- Do not take other ED medicines together with tadalafil.
Tadalafil is not intended for women or anyone under 18. Older adults may be more prone to secondary consequences. For serious warning signs see Serious risk indicators and when to contact a professional.
