Malegra DXT Plus contains two active ingredients: Sildenafil (for erectile dysfunction) Dapoxetine (for premature *****) Because it combines both, it can interact with several types of medicines and substances. Some interactions can be serious. 1. Nitrate medicines (VERY DANGEROUS) Avoid completely with sildenafil. Examples: nitroglycerin, isosorbide dinitrate/mononitrate Risk: severe drop in blood pressure, fainting, heart attack 2. Alpha-blockers (blood pressure / prostate drugs) Examples: tamsulosin, doxazosin, prazosin Risk: low blood pressure, dizziness, fainting 3. Other blood pressure medicines Can enhance BP-lowering effects Risk: dizziness or fainting, especially when standing up 4. Other erectile dysfunction drugs (PDE5 inhibitors) Example: tadalafil, vardenafil, avanafil Risk: overdose effects, severe side effects (headache, hypotension, priapism) 5. Antidepressants (important due to dapoxetine) Especially serotonergic drugs: SSRIs: fluoxetine, sertraline, paroxetine SNRIs: venlafaxine, duloxetine Tramadol, linezolid, triptans Risk: serotonin syndrome (agitation, sweating, fast heartbeat, confusion) 6. Strong CYP3A4 inhibitors (affect sildenafil + dapoxetine levels) Examples: ketoconazole, itraconazole, ritonavir, clarithromycin Risk: increased drug levels → stronger side effects 7. Alcohol (common but important) Risk: dizziness, fainting, low blood pressure, reduced ***** performance 8. Recreational drugs (“poppers” / amyl nitrite) Extremely dangerous with sildenafil Risk: life-threatening hypotension 9. Other serotonergic substances (supplements too) St. John’s Wort, some herbal antidepressant products Risk: serotonin-related side effects When to be especially careful Avoid this medicine or consult a doctor if you have: Heart disease, recent heart attack or stroke Low blood pressure or uncontrolled hypertension Liver or kidney disease Current antidepressant treatment If you want, tell me what other medicines you’re taking, and I can check the interaction more specifically.
