Does Tadalafil Expire? Shelf Life & Storage Guide
Tadalafil belongs to a class of medicine called phosphodiesterase type-5 (PDE5) inhibitors. Its trade name Cialis® is widely known, and it has since gained popularity in the treatment of impotence.
We often get asked by our patients taking tadalafil about the shelf life of this drug and if it would still be safe to take after the expiration date. Understanding whether tadalafil expires — and how long it remains effective — is essential to both medication safety and treatment outcomes.
As with all prescription medications, tadalafil comes with expiration dates and storage guidelines. These guidelines are designed to ensure that the drug remains safe and effective for its intended use.
In this guide we explain whether tadalafil expires, what you can expect if you take expired tadalafil, how long tadalafil lasts and the best ways to store it properly.

Does Tadalafil Expire?
Yes, tadalafil does expire. Like most medications, it has an expiration date defined by pharmaceutical companies and enforced by health agencies.
Drugs marketed in the United States are required by U.S. Food and Drug Administration (FDA) law to show identifiable expiration dates on their packaging. These dates inform you how long the manufacturer will guarantee that the drug is safe, stable and works as intended — assuming it has been stored properly.
However, Tadalafil has a unique feature of long duration. Once ingested, the time this drug stays active in your system (for an intended dose and use) can be anywhere from six hours to over 36 hours. But that doesn’t mean the cure is permanent.
Once tadalafil passes its expiration date, the chemical structure may begin to break down, which can reduce its potency and increase the chance that you will experience unwanted side effects.
Can You Use Expired Tadalafil?
Taking expired tadalafil is usually not recommended.
There are a number of good reasons why the FDA has recommended against taking expired medications. Medications can also chemically change over time, which might affect composition and stability.
Here are some risks that come with taking expired tadalafil:
- Changes in chemical structure
- Reduced medication strength
- Increased chance of bacterial contamination
- Higher risk of adverse reactions
- Unpredictable treatment results
If legitimate tadalafil fiend into synthetic, the medication can stop to work as arranged. In some cases, a breakdown product of a drug is different from that in its original formulation, which raises the potential for adverse effects.
For safety reasons, healthcare providers recommend throwing away tadalafil once it has expired.
When Does Tadalafil Expire?
Stored correctly, tadalafil typically retains its potency for three years after the date of manufacture.
This shelf life is determined through stability testing conducted by the companies that make the drugs. These tests assess the drug’s potency retention and chemical stability over time.
However, there are a number of factors that may influence how long tadalafil lasts for, including:
- Storage temperature
- Humidity levels
- Exposure to light
- Air exposure
- Packaging condition
The expiration date printed on a medicine packet is the last day that a manufacturer can confirm the safety and efficacy of a medication.
This time point represents the period after which the chemical composition and/or safety and/or efficacy of tadalafil may begin to degrade (i.e., no longer be safe or efficacious).
Is it Safe to Take Tadalafil After the Expiration Date?
Some concerns may arise when using expired tadalafil, especially regarding efficacy and safety.
Reduced Effectiveness
The main risk of ingesting expired tadalafil is reduced potency. The chemical structure of a medicine may gradually break down over time.
This can lead to:
- Decreased therapeutic effect
- Unpredictable results
- Ineffective treatment for erectile dysfunction
As the drug may no longer work, it also may not provide the appropriate treatment outcomes.
Chemical Degradation
The other is chemical changes that can occur post-expiration. Medications can be chemically transformed over time into the unexpected.
These changes may include:
- Breakdown of active ingredients
- Changes in chemical composition
- Formation of unstable substances
These changes can render the drug less effective, and they may increase health risks.
Increased Risk of Side Effects
Taking expired tadalafil may also increase the risk of side effects. Some natural expiration symptoms as a result of either medication:
- Muscle aches or back pain
- Nausea or stomach discomfort
- Headaches
- Vision disturbances
- Tingling or itching sensations
Rarely, when medicine is degraded, it may be contaminated with bacteria as well, causing other health-related issues as well.
“Anyone who’s experiencing unusual symptoms after taking expired medication should stop using the product and seek medical attention.”
How to Store Tadalafil Properly
Proper tadalafil storage is also critical to ensure that this medication remains effective throughout its entire expiration date.
Recommended storage practices include:
- Do not remove the medication from its original package
- Storage: Ambient, 68°F to 77°F (20–25°C)
- Store it in a cool, dry place
- Do not use it from moisture or sunlight
- Keep the container securely closed
Common storage venues include bedroom drawers, nightstands or kitchen cabinets located away from heat sources.
Bathrooms, generally speaking, are just not great storage places: Humidity and temperature shifts can cause medicines to break down more quickly.

Tadalafil used to treat erectile dysfunction is a relatively stable molecule.
Heat and Humidity
Such factors, including heat or humidity, can also cause medications to break down faster. Do not store tadalafil near stoves, heaters or in bathrooms (such conditions can shorten its shelf life).
Light Exposure
Sunlight can change the chemical structure of that medicine. Tadalafil should be stored in the original container to keep it protected from light.
Air Exposure
Oxygen can also accelerate the decomposition of medicine. After each use, keep the container tightly closed to limit air exposure that can affect the stability of the drug.
How to Dispose of Expired Cialis
Here are some ways to dispose of expired tadalafil:
When Tadalafil has passed its expiration date it must not be kept and used in the future, instead it must be thrown away.
If available, the F.D.A. says you should make use of drug take-back programs. These programs allow for safe collection and disposal of medications.
- If no take-back program is available, the F.D.A. recommends:
- Remove the medication from its real ingredients container.
- Add it to an unappealing substance such as dirt, coffee grounds or cat litter.
- Pour the mixture into an airtight bag or vessel.
- Throw the sealed container in your household trash.
- Before disposing of packaging, scratch out all personal information on prescription labels.
- Please do not flush down the toilet a medication unless the label advises it.
Final Thoughts
All medicines expire including tadalafil (Cialis®). If appropriately preserved it is usually effective for as long of three years from the production date.
You should not take expired tadalafil because the medicine may no longer be effective or cause adverse effects. Environmental factors including heat, humidity, light and exposure to air can also affect the drug’s stability.
Always check expiration dates, store medications properly and dispose of expired tadalafil correctly! A healthcare provider can describe the safest way to go about getting another supply if an expired prescription has popped up.
