Halltada (Tadalafil)

Halltada is prescribed for conditions that benefit from enhanced nitric‑oxide signaling and smooth‑muscle relaxation.

• Erectile dysfunction in adult males, improving ability to achieve and maintain an erection sufficient for sexual activity.
• Pulmonary arterial hypertension (off‑label), where increased cyclic GMP may help lower pulmonary vascular resistance.
• Benign prostatic hyperplasia symptoms (off‑label), potentially reducing urinary urgency and frequency.
• Use as part of combination therapy for refractory erectile dysfunction when monotherapy is insufficient.
• Clinical studies have evaluated tadalafil for improving exercise capacity in patients with pulmonary hypertension.

The safety profile of Halltada reflects the pharmacologic actions of tadalafil and includes both frequently reported and rare adverse events.

Common

• Headache: mild to moderate head pain that often resolves without treatment.
• Flushing: warmth and reddening of the face or neck.
• Indigestion (dyspepsia): upper‑abdominal discomfort or heartburn.
• Nasal congestion: blocked or runny nose.

Serious

• Priapism: prolonged erection lasting more than four hours that requires medical attention.
• Sudden loss of vision: abrupt visual impairment, possibly related to non‑arteritic anterior ischemic optic neuropathy.
• Sudden loss of hearing: rapid decrease or loss of hearing, sometimes accompanied by ringing.

Healthcare providers should assess individual risk factors before initiating Halltada to reduce the likelihood of complications.

• Unstable cardiovascular disease, such as recent myocardial infarction, unstable angina, or uncontrolled heart failure.
• Concomitant use of nitrate medications, which can cause severe hypotension.
• Severe hepatic or renal impairment, which may alter drug clearance.
• Existing hypotension or uncontrolled hypertension.
• Known hypersensitivity to tadalafil or any excipients in the formulation.
• Patients with inherited retinal disorders, such as retinitis pigmentosa.

Halltada can interact with several medicines, and some combinations should be avoided or used with caution.

Avoid

• Nitrate drugs (e.g., nitroglycerin, isosorbide dinitrate) because of the risk of profound blood‑pressure lowering.
• Guanylate cyclase stimulators such as riociguat, which may increase the risk of hypotension.

Use with caution

• Alpha‑blockers, which can also lower blood pressure.
• Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) that may raise tadalafil plasma levels.
• Strong CYP3A4 inducers (e.g., rifampin, carbamazepine) that may reduce tadalafil effectiveness.
