Opexa (Bilastine)

Bilastine works by selectively blocking peripheral histamine H1 receptors. This prevents histamine released during allergic reactions from binding to its receptors, thereby reducing vasodilation, increased permeability, and nerve stimulation that cause typical allergy symptoms.

The prescribed dose of Opexa is determined by a qualified healthcare professional. In most adult patients, a single 20 mg tablet taken once daily is common, but the exact regimen should follow the prescriber’s instructions and local labeling.

Bilastine is classified as pregnancy category B in many regions, indicating no proven risk in animal studies, but human data are limited. It should only be used during pregnancy or lactation if the potential benefit justifies the potential risk, after consulting a physician.

To place an order, submit an enquiry on the Opexa product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Bilastine offers a non‑sedating profile compared with first‑generation antihistamines and has a rapid onset of action. Unlike some second‑generation agents, it shows minimal metabolism via CYP enzymes, reducing the likelihood of drug‑drug interactions.

Store Opexa tablets at room temperature, below 25 °C, in the original blister pack or container. Protect them from moisture, excessive heat and direct sunlight to maintain potency throughout the shelf life.

Opexa is taken orally with a glass of water. It can be taken with or without food, but consistency with meals may help reduce occasional gastrointestinal discomfort.

Serious adverse events, although rare, include anaphylaxis, angioedema, severe skin reactions such as Stevens‑Johnson syndrome, and cardiac arrhythmias. Patients should seek immediate medical attention if they experience swelling of the face or throat, rash, or irregular heartbeats.

Opexa is contraindicated in individuals with known hypersensitivity to bilastine or any tablet excipients. Caution is advised for patients with severe renal impairment, and it should be avoided in those taking strong CYP3A4 inhibitors unless directed by a physician.
