Your dizziness, weakness, and sleep issues could indeed be related to low blood pressure or side effects from medications like Libotryp and Zepis, which can cause drowsiness. Additionally, Rozavel (rosuvastatin) can sometimes cause muscle pain, while your B12 and Vitamin D levels might still be stabilizing. Since you are already taking multiple B12 supplements (Neurobion and Nervup OD), your symptoms may not simply be a need for more injections. Please consult your doctor to check your blood pressure, review your current medication doses, and ensure you are not duplicating vitamin supplements.

This tingling is likely a temporary nerve irritation. Alcohol can temporarily affect nerve function, especially if there is an underlying sensitivity or vitamin B deficiency, which your Neurobion Forte (vitamin B complex) helps manage. While mild immune responses after a COVID-19 vaccine can occasionally cause temporary nerve sensations, your history suggests your nerves may just be temporarily sensitive. For now, please stay well-hydrated, avoid alcohol, and continue your Neurobion Forte as directed. Gentle stretching can also help. If the tingling worsens, spreads, or is accompanied by weakness or numbness, please consult your doctor for a personalized evaluation.

Medications like Jotter 100 (gabapentin) can take two to four weeks to show their full effect, so ten days is often too early to feel significant relief. Regarding Neurobion Forte, it contains B-complex vitamins, which overlap significantly with your Supradyn multivitamin. Taking both is generally not recommended as it can lead to an unnecessary double-dose of these vitamins. I suggest holding off on Neurobion Forte and speaking with your doctor, who can safely adjust your gabapentin dose or streamline your vitamins to better manage your symptoms.

Nervaline Max and Neurobion are not therapeutically equivalent, as they contain different active ingredients and dosages. Neurobion is a supplement containing specific B vitamins (B1, B6, and B12) to support nerve health. Nervaline Max typically has a different formula, which often includes additional ingredients like alpha-lipoic acid or different vitamin strengths depending on the specific product. Since formulations can vary, I highly recommend sharing both packages with your doctor or pharmacist.

Your daytime sleepiness and constipation may indeed be related to your medications. First, Cetirizine, an antihistamine, is a well-known cause of drowsiness. Second, taking calcium (Shelcal) or antacids (Digene) close to your thyroid medication, Thyronorm (levothyroxine), can severely block its absorption. This can lower your thyroid hormone levels, leading to fatigue and constipation. To help, always take your Thyronorm on an empty stomach in the morning, and wait at least four hours before taking any calcium, multivitamins, or antacids. Please consult your doctor to check your thyroid levels and safely review your daily medication schedule.

These symptoms are often linked; nasal congestion can block the Eustachian tube that connects your nose and ear, causing pressure and ringing. Neurobion Forte contains B vitamins, which support nerve health but will not relieve nasal congestion. To help soothe your symptoms, you might try generic saline nasal sprays or warm steam inhalation to clear your nasal passages. I highly recommend consulting an ear, nose, and throat specialist for a proper evaluation of your ears and sinuses.
