Megalis (Tadalafil) Buyer and Patient Handbook in Singapore
What is Megalis?
Megalis is a 20 mg oral tablet belonging to the phosphodiesterase-5 inhibitor class, used to treat Erectile Dysfunction (ED). It improves blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. Megalis is approved by both the FDA and the Health Sciences Authority (HSA) of Singapore and is supplied as a single-strength pill.
Who Should Use Megalis?
- Men diagnosed with erectile dysfunction
- Adults aged 18 years and older
- Individuals seeking an on-demand solution (taken before sexual activity)
- Patients whose health status permits safe use of PDE-5 inhibitors
How Does It Work?
Megalis blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic GMP-a messenger that relaxes smooth muscle in the penile tissue. By preserving cyclic GMP, blood vessels dilate and more blood reaches the penis during sexual arousal, facilitating an erection.
Safety note: Megalis has no known abuse potential, but it should not be combined with nitrate medication because of a serious blood-pressure drop risk.
Why Choose Megalis?
- Cost-effective: As a generic formulation, Megalis offers the same clinical benefit as brand-name tadalafil at a lower price.
- Predictable onset: Takes effect within 30-60 minutes and can last up to 36 hours, providing flexibility for spontaneous intimacy.
- Off-label uses such as Pulmonary Arterial Hypertension are possible, but you must discuss them with a healthcare professional.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 20 mg taken orally, preferably 30 minutes to 2 hours before planned sexual activity. Do not exceed one dose per day.
How to Take
- Swallow the tablet whole with a full glass of water.
- It can be taken with or without food; a heavy-fatty meal may delay onset.
Missed Dose
If you forget to take Megalis before sexual activity, do not take a later dose to make up for it. Wait until the next opportunity and resume the usual schedule.
Overdose
In case of suspected overdose (e.g., taking more than 20 mg), seek immediate medical attention. Symptoms may include dizziness, low blood pressure, or a prolonged erection lasting over 4 hours.
Special Populations
| Group | Recommendation |
|---|---|
| Elderly (≥65 y) | Start with 10 mg if renal or hepatic function is reduced; otherwise 20 mg is acceptable. |
| Renal impairment | Use a lower dose (10 mg) if creatinine clearance < 30 mL/min. |
| Hepatic impairment | Reduce to 10 mg for moderate disease; avoid if severe. |
| Children | Not approved; use is contraindicated. |
Lifestyle & Diet
- Alcohol: Moderate consumption (≤2 drinks) is unlikely to affect efficacy, but excess alcohol may reduce erection quality.
- Grapefruit: Avoid large amounts as grapefruit juice can increase tadalafil levels, raising the risk of side effects.
- Exercise: Normal physical activity does not interfere with Megalis, but avoid vigorous exercise immediately after dosing if you feel dizzy.
Precautions and Warnings
- Do not use if you are currently taking nitrate medication (e.g., nitroglycerin).
- Avoid if you have severe cardiovascular disease, uncontrolled Hypertension, or a history of priapism.
- Inform your healthcare provider about any heart conditions, recent stroke, or eye disorders (e.g., non-arteritic anterior ischemic optic neuropathy).
Drug Interactions
| Drug Class | Interaction Risk | Recommended Action |
|---|---|---|
| Nitrates (e.g., nitroglycerin) | Severe hypotension | Contra-indicated |
| Alpha-blockers (e.g., tamsulosin) | Possible blood-pressure drop | Start with 5 mg, monitor |
| Cytochrome P450 3A4 inhibitors (e.g., ketoconazole) | Increased tadalafil levels | Reduce dose to 10 mg |

Frequently Asked Questions
How quickly does Megalis start working?
Megalis typically begins to work within 30 to 60 minutes after ingestion, but maximum effect may take up to 2 hours.
Can I take Megalis with food?
Yes. A high-fat meal may delay onset, so for fastest results take it on an empty stomach or with a light meal.
What should I do if I experience a painful erection lasting more than 4 hours?
Treat it as a medical emergency. Seek immediate care at the nearest emergency department; prompt treatment reduces the risk of permanent damage.
Is it safe to drink alcohol while using Megalis?
Moderate alcohol intake generally does not interfere, but excessive drinking can lower erection quality and increase side-effects.
Can I use Megalis if I have high blood pressure?
If your blood pressure is well-controlled and you are not on nitrate medication, Megalis is usually safe. Discuss your condition with a healthcare professional first.
Will Megalis improve my libido?
Megalis does not increase sexual desire; it only helps achieve an erection when sexual stimulation occurs.
How often can I take Megalis?
Do not exceed one dose per day. Daily dosing is possible at lower strengths (e.g., 5 mg) under medical guidance, but the 20 mg tablet is intended for on-demand use.
Is Megalis suitable for men over 70 years old?
Older men may benefit, but a lower starting dose (10 mg) is recommended, especially if kidney or liver function is reduced.
Can I purchase Megalis over the counter in Singapore?
Megalis is a prescription-only medicine under HSA regulations; you need a valid prescription to obtain it from a licensed pharmacy.
What if I miss a dose and still want to have intercourse later that day?
Do not take an additional tablet. Wait until the next day to resume the usual dosing schedule.

Reviews
First time trying 20mg. Took it around 6 PM. Holy hell, the back ache started around midnight. It feels like I ran a marathon, specifically in my lower lumbar. It works, no question there, but the body pain tradeoff is rough. Seriously considering splitting the 20mg into two 10mg doses next time. Any vets out there agree? Staying well-hydrated is key, drank maybe 3 liters of water just to try and flush the pain.
Been on this off and on for almost a year now. The trick is to take it right after a large meal, like dinner, even though the instructions say fasting is okay. Absorbs slower, which seems to reduce the intensity of the "blue vision" by maybe 50%. The congestion is still a major factor though; feels like a permanent head cold for 36 hours. I always keep a nasal spray handy. This one is reliable, but definitely not discrete if you worry about the flushed face look.
The absolute worst side effect for me is the acid reflux. It hits hard, even if I take it hours before bed. I found taking it alongside a powerful antacid, like a prescription PPI, helps dull the burn significantly. I usually split the 20mg pill into quarters and only take 5mg every other day, just to maintain a baseline level in my system. Works better for spontaneity and way less pain. High dose is overkill unless you really need the weekend coverage.
Newbie alert. Took the full 20mg dose, thinking more is better. Mistake. The efficacy was great, truly long-lasting, almost 40 hours. But the headache arrived on day two, a pounding sinus pressure right behind the eyes that Motrin couldn't touch. It felt like a bad hangover without the fun night before. Next attempt, I'm definitely sticking to 10mg. Is it normal to have mild heartburn too? Worried about long-term use with the intensity of these immediate effects.
I use the 20mg only for special occasions. It works, but it interferes with my sleep so badly. I get maybe four hours of deep sleep, then I'm wired. To counter this, I try to take it first thing in the morning, around 8 AM, even though I don't need the effect until that evening. This "front-loading" hack ensures the chemical peak wears off enough by 11 PM that I can actually fall asleep without the buzzing feeling. Still worth it, but requires planning.
Five years on this stuff. My only complaint now is the sheer dry mouth. I wake up feeling like I've been chewing cotton wool all night. The hack I learned: drink a glass of milk before bed, not water. Water just makes you pee, milk seems to coat the mouth better. Also, avoid extremely hot showers when it's active; the blood pressure change makes me feel dizzy sometimes. Don't stress about the pink face, nobody in the region notices anyway.
Weird complex results. It works flawlessly for physical effects, making weekend trips stress-free. However, it seems to give me short-term memory fog. I struggle to recall specific details from conversations I had the day after taking it. It’s subtle, but noticeable, professionally frustrating. I tried reducing the dose to 15mg (I cut the pill) and the memory fog lessened, but the physical effect was also weaker. Torn on this one, success comes with a brain tax.
I love how long it lasts, but the muscle ache is completely unpredictable. Sometimes it's a mild stiffness, sometimes it's severe cramping in my thighs and shoulders. I discovered that taking a high-dose Magnesium supplement (Glycinate form) about two hours before the Tadalafil completely eliminates the cramping spasms. Life saver. If you skip the mag, expect to be walking funny the next day. It's an essential stack for anyone using 20mg frequently.
