Aurogra and Phenelzine (Nardil): MAOI Safety Checks

Phenelzine (sold as Nardil and in generic form) is an older type of antidepressant called a monoamine oxidase inhibitor (MAOI). It’s usually reserved for depression that hasn’t responded to other treatments, or for “atypical” depression and certain anxiety conditions. It works well for many people, but it comes with more rules than almost any other medicine in common use: food restrictions, a long list of drug interactions and blood pressure effects in both directions.

Aurogra is an Indian-made brand of sildenafil citrate, most often sold as Aurogra 100, used to treat erectile dysfunction. Men taking phenelzine commonly experience sexual side effects, so the question “Can I use Aurogra?” comes up often.

The direct interaction between sildenafil and phenelzine is not a contraindication. Interaction references classify MAOI–sildenafil combinations as moderate, mainly because both can lower blood pressure. But with an MAOI, the bigger dangers often sit around the edges: what else is in the ED product, what else you’re taking, and how to tell a harmless side effect from an MAOI emergency. This guide breaks the pharmacist’s checks into three layers.

At a Glance

Direct interaction: Moderate. Additive lowering of blood pressure, especially on standing.
Bigger hidden risk: “Herbal” or counterfeit ED products that contain stimulants, which can trigger a dangerous blood pressure spike with an MAOI.
Key check: Any decongestant, cough medicine, stimulant or other antidepressant on your list.
Dose: A cautious start (often 25 mg) is a reasonable question to ask, given phenelzine’s own blood pressure effects.
Never: combine sildenafil with nitrates or riociguat.

Layer 1: The Direct Interaction (Blood Pressure Going Down)

How phenelzine affects blood pressure

It surprises many people that a drug famous for causing dangerous high blood pressure (with certain foods) more commonly causes low blood pressure day to day. Orthostatic hypotension (a drop in blood pressure when standing) is one of phenelzine’s most frequent side effects. The UK product information advises close monitoring for postural hypotension and notes that hypotensive effects can occur in people with high, normal or low blood pressure (phenelzine SmPC). It also states that phenelzine may potentiate the effects of antihypertensive medicines (Nardil SmPC).

How sildenafil adds to it

Sildenafil relaxes blood vessels and causes a mild, temporary fall in blood pressure. On its own, that’s usually not noticeable. On top of phenelzine’s postural effect, it can make dizziness, light-headedness or fainting more likely, especially when you stand up after sex or get up at night.

Interaction databases describe the sildenafil–MAOI pairing as having additive hypotensive effects and advise caution and monitoring for low blood pressure, particularly in the first weeks of treatment (MecDDI sildenafil–MAOI entry; Drugs.com MAOI with sildenafil). Drugs.com lists sildenafil among the medicines that interact with phenelzine (phenelzine interactions index).

What the pharmacist checks in Layer 1

Do you get dizzy when you stand? If yes, you already have little blood pressure reserve.
How long have you been on phenelzine, and has the dose changed recently? Postural hypotension is often worse during dose increases.
What other blood pressure–lowering medicines do you take? Alpha-blockers like tamsulosin, diuretics and antihypertensives add up.
What dose of sildenafil is planned? Aurogra 100 mg is the maximum dose. A lower starting dose, such as 25 mg, is a sensible question to raise with your prescriber.

For practical ways to manage dizziness, see our guide on Aurogra with orthostatic hypotension.

Layer 2: The Hidden Risks (Blood Pressure Going Up)

This is where an MAOI changes the conversation. Phenelzine stops the body breaking down certain chemicals that raise blood pressure. When something adds more of those chemicals, blood pressure can shoot dangerously high, a hypertensive crisis. Sildenafil itself doesn’t do this. But several things that travel alongside ED treatment can.

Danger 1: “Herbal” or “natural” sex pills

Products marketed as natural sexual enhancers sometimes contain stimulants or substances such as yohimbine, which can raise blood pressure and heart rate. Others have been found to contain hidden PDE5 inhibitors. With an MAOI, a stimulant-containing product is a genuine risk. The phenelzine product information warns against sympathomimetic and related compounds because MAOIs can potentiate them (Nardil SmPC). Our article on natural Viagra substitutes explains why “natural” doesn’t mean safe.

Danger 2: Counterfeit Aurogra

Aurogra is widely sold online, and counterfeit ED tablets have been found to contain wrong doses, different drugs and contaminants. For most people, that’s a quality problem. For someone on an MAOI, an unknown ingredient could be a safety problem. Buy only through a prescription and a registered pharmacy. See how to spot fake ED medicines.

Danger 3: Cold and flu remedies

Decongestants such as pseudoephedrine and phenylephrine, and the cough suppressant dextromethorphan, are among the most important things to avoid with phenelzine. They’re common in over-the-counter cold remedies. They don’t interact with sildenafil directly, but a pharmacist reviewing your ED medicine should check for them because they’re a bigger MAOI risk than sildenafil itself.

Danger 4: Other antidepressants and “mood” products

Phenelzine must not be combined with SSRIs, SNRIs, tricyclics, bupropion, buspirone, triptans and several other drugs, and switching between them needs a washout period. St John’s wort and some supplements are also problematic. If you’ve seen information about Aurogra and bupropion, note that bupropion itself is not allowed with phenelzine.

Danger 5: Tyramine-rich food and drink

Aged cheeses, cured meats, fermented soy, some tap beers and other tyramine-rich foods can trigger a hypertensive crisis with phenelzine. A romantic meal with aged cheese and draught beer isn’t a sildenafil interaction, but it’s a real MAOI risk on the same evening.

Layer 3: Your Underlying Health

Both medicines carry their own cautions about heart and blood vessel health:

Phenelzine should not be used in people with cerebrovascular disease or congestive heart failure, according to UK product information, and caution is advised in cardiovascular disease.
Sildenafil shouldn’t be used where sexual activity is inadvisable (such as unstable angina or severe heart failure), after a recent heart attack or stroke (per some labels), with very low blood pressure, or with nitrates or riociguat.
Liver disease is a contraindication for phenelzine and calls for a lower sildenafil starting dose.
Surgery and dental procedures: phenelzine is usually stopped before elective surgery because of anaesthetic interactions. Mention both medicines to any surgeon or dentist.

If you have heart disease and take phenelzine, your prescriber should review whether sildenafil is suitable at all. See the safest drugs for ED for how doctors weigh these risks.

Why Phenelzine Is Still Prescribed

With all these rules, you might wonder why anyone takes phenelzine. The answer is that it can work when other antidepressants haven’t. MAOIs have a long track record in treatment-resistant depression, depression with “atypical” features such as oversleeping and heavy fatigue, and some anxiety disorders. For people who’ve tried several other medicines without success, phenelzine can be life-changing.

That context matters for ED. Stopping phenelzine to make sex easier could risk a relapse of serious depression. The goal is to find an ED approach that fits safely around a treatment that’s working.

Planning a Date Night on Phenelzine

A relaxed evening is part of good intimacy. Here’s how to keep it MAOI-friendly:

Usually safer choices	Avoid or check with your prescriber
Fresh meat, poultry and fish, cooked and eaten fresh	Aged, cured, smoked or fermented meats (salami, pepperoni)
Fresh cheeses such as cottage cheese, ricotta and cream cheese	Aged cheeses (mature cheddar, blue cheese, parmesan)
Fresh vegetables and fruit	Fermented soy products (soy sauce, miso, tofu that’s fermented), sauerkraut, kimchi
Non-alcoholic drinks	Draught (tap) beer and unpasteurised beers; alcohol in general increases dizziness
Freshly prepared sauces	Yeast extracts (Marmite, Vegemite), broad bean pods

Your prescriber or dietitian will have given you a personalised list; follow that if it differs. Eating out needs extra care, since dishes can contain hidden aged cheese, cured meat or soy sauce. If you’re unsure about a dish, choose something simpler.

Headache: Harmless Side Effect or Emergency?

Here’s a practical problem unique to this combination. Headache is one of sildenafil’s most common side effects. A severe headache is also the classic first sign of an MAOI hypertensive crisis. You need to be able to tell them apart.

Feature	Typical sildenafil headache	Possible MAOI hypertensive crisis
Onset	Gradual, within an hour or so of the dose	Often sudden and severe, may follow a food, drink or other medicine
Feel	Dull, mild to moderate, often with flushing	Intense, throbbing, often at the back of the head
Other symptoms	Flushing, stuffy nose, mild indigestion	Stiff or sore neck, palpitations, sweating, nausea or vomiting, chest pain, light sensitivity, dilated pupils
Blood pressure	Normal or slightly lower	Markedly raised
What to do	Rest, fluids; tell your pharmacist if bothersome	Seek emergency help immediately

If you’re unsure, treat it as an emergency. If you have a home blood pressure monitor, a very high reading confirms the need for urgent care. Tell emergency staff that you take phenelzine and have taken sildenafil, with timings.

Why Phenelzine Users Often Need ED Help

Sexual side effects are common with phenelzine, including reduced desire, erection difficulties, delayed ejaculation and difficulty reaching orgasm. Depression itself also lowers desire and affects erections. So when a man on phenelzine notices sexual problems, it can be hard to tell whether the cause is the illness, the medicine or something physical.

Before adding Aurogra, ask your prescriber:

Did the sexual problems start or worsen after phenelzine was started or increased?
Is the main problem erections, desire or orgasm? Sildenafil helps erections, not desire or orgasm.
Are there physical causes to check, such as blood pressure, diabetes, hormones or heart health?
Could a dose adjustment help without risking a relapse of depression?

Never stop or reduce phenelzine on your own. Stopping abruptly can cause withdrawal symptoms, and depression can return.

The Pharmacist’s Review, Summarised

Bringing the three layers together, a thorough pharmacist review covers:

Phenelzine dose, duration and any recent changes
Postural dizziness and current blood pressure
Other blood pressure–lowering medicines, especially alpha-blockers
Nitrates or riociguat (contraindicated with sildenafil)
Strong CYP3A4 inhibitors that raise sildenafil levels
Over-the-counter cold remedies, cough syrups and stimulants
Herbal supplements, “natural” sex boosters and St John’s wort
Other antidepressants and recent switches (washout periods)
Heart, liver and cerebrovascular health
Source and authenticity of the Aurogra
Planned sildenafil dose (asking about 25 mg as a start)
Counselling on headache warning signs and dizziness

Practical Tips for Using Sildenafil Safely on Phenelzine

If your prescriber agrees that sildenafil is appropriate:

Start low. Ask about 25 mg rather than a full 100 mg Aurogra tablet.
Stand slowly. Sit on the edge of the bed for a minute before getting up afterwards.
Stay hydrated, unless you’re on a fluid restriction.
Keep your MAOI diet, especially on evenings you plan to use sildenafil. Avoid aged cheese, cured meats and draught beer.
Avoid alcohol, which worsens dizziness and may contain tyramine (especially tap beer).
Check every new medicine, including cold and flu remedies, with your pharmacist.
Keep a blood pressure monitor at home if your prescriber recommends it.
Carry an MAOI alert card listing phenelzine and the medicines you shouldn’t take.

Over-the-Counter Products to Check Before Using Them With Phenelzine

When men buy ED products, they sometimes pick up other items at the same time. This table lists common over-the-counter categories that matter with phenelzine. Always check with a pharmacist before using any of them.

Product type	Examples of ingredients	Concern with phenelzine
Decongestants	Pseudoephedrine, phenylephrine, ephedrine	Risk of hypertensive crisis
Cough suppressants	Dextromethorphan	Serious reactions, including serotonin toxicity
“Natural” sex boosters	Yohimbine, undeclared stimulants or PDE5 inhibitors	Blood pressure spikes or unpredictable effects
Weight-loss and energy products	Stimulants, caffeine-heavy formulas	Raised blood pressure and heart rate
Herbal mood products	St John’s wort, tryptophan-containing supplements	Serotonergic interactions
Some pain medicines	Tramadol, pethidine (prescription)	Serious interactions
Hay fever and allergy combinations	Antihistamine plus decongestant	Decongestant component is the risk

Switching Antidepressants: Washout Periods Explained

If your psychiatrist decides to switch you from phenelzine to another antidepressant, or vice versa, a gap is needed between the two. UK product information gives examples: phenelzine shouldn’t be given within 14 days of other MAOIs and certain drugs, about five weeks should pass after stopping fluoxetine, and around two weeks after paroxetine. Conversely, many serotonergic antidepressants shouldn’t be started until at least 10 days to two weeks after stopping phenelzine.

Why this matters for ED: during a switch, men are sometimes left with sexual side effects from one drug while waiting for the next. It’s tempting to add an ED product at this stage. Sildenafil itself isn’t affected by these washout rules, but it’s a good time for a pharmacist to double-check your full list, including any supplements you may have started to cope.

A Simple MAOI Alert Card

Carrying a card in your wallet or a note in your phone’s medical ID can prevent dangerous mistakes in emergencies. A useful card includes:

“I take phenelzine (an MAOI), [dose] daily.”
“Avoid: decongestants, dextromethorphan, pethidine, tramadol, other antidepressants, stimulants and adrenaline in local anaesthetics.”
“I sometimes take sildenafil for ED. Last dose: ____.”
Your prescriber’s name and your pharmacy’s phone number.

A Short Guide for Partners

Partners can play a helpful role in keeping this combination safe:

Know that a sudden, severe headache with neck stiffness or palpitations is an emergency, not a normal side effect.
Help plan meals that follow the MAOI diet on evenings when sildenafil may be used.
Encourage slow standing after sex and on night-time bathroom trips.
Avoid buying “natural” enhancement products as gifts or surprises.
Be part of conversations with the prescriber if he’s comfortable with that.

Signs Your Phenelzine Plan May Need a Review

Sometimes the problem isn’t sildenafil but the balance of your phenelzine treatment. Tell your prescriber if you notice:

Frequent dizziness or fainting on standing, even without sildenafil
Swollen ankles or unexplained weight gain
Persistent insomnia or daytime sleepiness
Muscle twitching or unusual restlessness
Sexual side effects that are affecting your relationship or mood
Any sudden severe headaches, even if they settled

These may lead to a dose adjustment, a change in timing, or extra monitoring. Making sure phenelzine is well tolerated often makes adding an ED treatment safer, too. And if ED is your main concern, saying so clearly helps your prescriber weigh up the options.

Alternatives to Discuss

Other PDE5 inhibitors: tadalafil, vardenafil and avanafil share the same blood pressure–lowering effect. Tadalafil’s longer action means any dizziness may last longer. See sildenafil vs tadalafil.
Vacuum erection devices: no drug interactions.
Alprostadil: works locally; discuss suitability.
Psychological approaches: sex therapy and counselling can help, particularly where depression and anxiety are involved. See how to beat psychological ED.
Antidepressant review: in some cases, a psychiatrist may consider whether a different treatment approach could reduce sexual side effects, with appropriate washout periods.

One Pharmacy, One Record

For anyone on an MAOI, using a single pharmacy for every prescription and over-the-counter purchase is one of the simplest safety steps available. It means every new item, including an ED medicine, is checked against your phenelzine automatically. If you also use an online service, tell your regular pharmacist what you’ve been prescribed so your record stays complete.

Frequently Asked Questions

Is it safe to take Aurogra with phenelzine?

The combination isn’t contraindicated, but it needs caution because both can lower blood pressure. A prescriber should review your blood pressure, heart health and full medication list first.

Can sildenafil cause a hypertensive crisis with an MAOI?

Sildenafil itself isn’t known to trigger hypertensive crises. The risk comes from other things: stimulant-containing “natural” products, decongestants, certain cough medicines, other antidepressants and tyramine-rich foods.

What dose of Aurogra should I take on phenelzine?

That’s for your prescriber to decide. Given phenelzine’s blood pressure effects, asking about a 25 mg starting dose is reasonable. A 100 mg tablet is the maximum, not a starting point.

I got a headache after taking Aurogra. Should I worry?

Mild headache with flushing is a common sildenafil side effect. A sudden, severe headache with neck stiffness, palpitations, sweating or vomiting could signal a hypertensive crisis and needs emergency care.

Can I take a cold remedy while using phenelzine and Aurogra?

Many cold remedies contain decongestants or dextromethorphan, which are dangerous with phenelzine. Always ask a pharmacist before taking any over-the-counter medicine.

Does phenelzine cause erectile dysfunction?

Sexual side effects, including erection problems and delayed orgasm, are common with phenelzine. Discuss them with your prescriber rather than stopping the medicine.

What about other MAOIs like tranylcypromine or isocarboxazid?

The same principles apply: additive blood pressure lowering with sildenafil, and the same hidden risks from stimulants, decongestants and other antidepressants.

The Bottom Line

Sildenafil and phenelzine have a moderate, manageable direct interaction: both lower blood pressure, so dizziness and fainting are the main concerns. The bigger dangers lie around the combination, in counterfeit or “herbal” ED products, cold remedies, other antidepressants and tyramine-rich food, any of which can trigger an MAOI crisis. A thorough pharmacist check covers all three layers, and a good plan includes a cautious dose, a reliable source, careful standing and a clear understanding of which headaches are harmless and which are an emergency. Ask the questions, keep one pharmacy, and never treat a sudden severe headache as just another side effect.
