EREC® Tablets: A Comprehensive Guide to Erectile Dysfunction Medication

EREC® Tablets, containing Sildenafil 100 mg, offer relief for individuals suffering from erectile dysfunction (ED). This comprehensive guide aims to provide valuable insights into EREC®, including its composition, indications, dosage, precautions, contraindications, side effects, and storage recommendations.

Composition and Properties


  • Each tablet contains Sildenafil 100mg.


  • Sildenafil acts as a phosphodiesterase inhibitor, competitively inhibiting phosphodiesterase enzyme type 5. This inhibition increases levels of cGMP, a second messenger of nitric oxide, promoting vasodilation in the penis. This mechanism relaxes corpus cavernosal smooth muscles, facilitating increased blood flow and erection.


EREC® Tablets are primarily indicated for erectile dysfunction, providing effective relief for individuals experiencing difficulties in achieving or maintaining erections.

Dosage Recommendations

  • Adult Dosage: A half tablet (50 mg Sildenafil) should be taken orally before sexual activity, between half to four hours prior.
  • Dosage Range: Daily dosages range from 25mg to 100mg, with a maximum frequency of once daily.
  • Special Considerations: Patients with hepatic impairment, severe renal failure, or over 65 years old should start with a 25 mg dose to minimize the risk of adverse effects.


  • Nitrate Use: EREC® Tablets are contraindicated in patients using organic nitrates due to potential hypotensive effects.
  • Cardiovascular Risks: Individuals with preexisting cardiovascular diseases or retinal nerve atrophy should avoid EREC® use.
  • Priapism: Prolonged erection exceeding four hours or painful erections should prompt immediate medical attention.

Side Effects

  • Body: Side effects may include facial edema, headache, photosensitivity reactions, and allergic reactions.
  • Cardiovascular: Reports of angina, syncope, hypotension, and myocardial infarction have been noted.
  • Musculoskeletal: Rare occurrences of musculoskeletal pain, arthritis, and tendon rupture have been reported.
  • Nervous System: Neurological side effects such as tremors, vertigo, depression, and insomnia may occur.
  • Special Senses: Visual disturbances, conjunctivitis, and eye pain have been reported.

Drug Interactions

  • Sildenafil may interact with medications such as Cimetidine, erythromycin, ketoconazole, and ritonavir, affecting serum levels.
  • Rifampicin decreases sildenafil serum levels.


  • Caution is advised in patients with recent myocardial infarction, stroke, or life-threatening arrhythmias.
  • Patients with resting hypotension or hypertension, cardiac failure, or coronary artery disease require careful monitoring.
  • Anatomical penile deformities, sickle cell anemia, multiple myeloma, leukemia, or retinitis pigmentosa warrant precautionary measures.

Storage and Packaging

  • EREC® Tablets should be stored below 30°C, away from direct sunlight, and out of reach of children.
