Here is a thorough breakdown of medicines used to decrease sexual desire (libido) in men:

Medicines That Decrease Sexual Desire in Men

These drugs are referred to as anti-libidinal agents or antiandrogens. They work mainly by reducing testosterone activity - either by lowering testosterone production or blocking its receptors. They are used in conditions like prostate cancer, paraphilias, and sex offender treatment programs.

1. Antiandrogens (Most Direct Effect)

These drugs work via CNS androgen receptors to reduce sexual desire. Their effects range from partial reduction to near-complete loss of libido.
DrugClassMechanism
Cyproterone acetateSteroidal antiandrogenBlocks androgen receptors; also has progestogenic activity
BicalutamideNon-steroidal antiandrogenBlocks androgen (testosterone/DHT) receptors
FlutamideNon-steroidal antiandrogenCompetitive androgen receptor antagonist
"Estrogens and drugs with antiandrogenic action such as ketoconazole, LHRH agonists non-steroidal (bicalutamide) and steroidal (cyproterone acetate) can diminish sexual function." - Smith and Tanagho's General Urology, 19th Edition

2. LHRH (GnRH) Agonists - Most Potent

These cause "medical castration" by suppressing testosterone to near-zero levels.
  • Leuprolide (Lupron)
  • Triptorelin
  • Goserelin
"The near-complete androgen deprivation achieved by medical castration with LHRH agonists results in a profound loss of sexual desire, which is usually accompanied by erectile dysfunction." - Smith and Tanagho's General Urology

3. SSRIs (Antidepressants)

Selective Serotonin Reuptake Inhibitors reduce libido as a side effect (by raising serotonin, which inhibits dopamine - the "desire" neurotransmitter).
  • Fluoxetine (Prozac)
  • Sertraline (Zoloft)
  • Paroxetine (Paxil) - strongest libido-reducing effect among SSRIs
"It is estimated that up to 50% of patients using SSRIs experience a change in sexual function." - Smith and Tanagho's General Urology

4. Other Drugs That Lower Libido

DrugHow it Reduces Libido
SpironolactoneWeak antiandrogen effect; also causes gynecomastia
KetoconazoleInhibits testosterone synthesis
Medroxyprogesterone acetate (MPA)Progestin; lowers testosterone levels
EstrogensSuppress testosterone via negative feedback on the pituitary
Opioids (morphine, methadone)Suppress the hypothalamic-pituitary axis
Finasteride5-alpha reductase inhibitor; mild effect (~5% of men)
Antipsychotics (haloperidol, risperidone)Raise prolactin, which suppresses testosterone
Beta-blockers (propranolol)CNS effects that reduce sexual drive

Summary by Use Case

  • Prostate cancer: LHRH agonists (leuprolide, triptorelin) + bicalutamide
  • Paraphilias / forensic psychiatry: Cyproterone acetate, MPA, triptorelin
  • Side effect scenario: SSRIs, spironolactone, antipsychotics, opioids
Note: These medications should only be used under medical supervision. Reducing libido pharmacologically carries risks including osteoporosis (with long-term androgen deprivation), depression, hot flashes, and cardiovascular effects.

Without side effects ..which any normal person can take...in Pakistani brand names

I need to be straightforward with you here before answering.
There is no medicine that reduces sexual desire "without side effects." Every drug that lowers libido works by altering hormones or brain chemistry, and all of them carry real risks - even at low doses.

Important Concerns

Why this question matters:
If you are asking for yourself - to manage unwanted urges or a personal condition - that is completely valid, but you must see a doctor. A psychiatrist or urologist in Pakistan can prescribe the right option safely.
If the intent is to give this to someone else without their knowledge - that is:
  • Medically dangerous (could cause serious harm)
  • Legally a criminal act in Pakistan under the law

What a Doctor Can Prescribe in Pakistan

If you have a legitimate medical reason, a Pakistani doctor may consider:
DrugPakistani Brand NameClass
FluoxetineProzac, Floxet, DeproxSSRI antidepressant
SertralineSertin, Serlift, ZoloftSSRI antidepressant
Cyproterone acetateAndrocurAntiandrogen (prescription only)
Even SSRIs - the "mildest" option - commonly cause sexual side effects, sleep changes, and mood shifts. None of these are risk-free.

My Recommendation

Please consult a psychiatrist or urologist in Pakistan. Describe your situation honestly. They can assess whether medication is appropriate and monitor for side effects safely.
If this is about managing compulsive sexual behavior, a psychiatrist can also offer non-medication approaches (CBT therapy) that have no drug side effects at all.

Safest to useNeeds some caution
B-Complex, Zinc, MultivitaminsCyproheptadine (mild drowsiness)
Trimetabol SyrupMosegor (slight sedation)
Most important: Weight gain medicines work best alongside increased calorie intake and protein in your diet. Medicine alone will not cause healthy weight gain without eating more.

Recommendation: Start with Mosegor-V Syrup or Practin tablets - both are widely available at any pharmacy in Pakistan, inexpensive, and very safe for normal healthy adults. If you want zero side effects, go with B-Complex + Zinc supplements first.
